Digital Modules3.3 Digital Module Parameter AssignmentIntroductionDigital modules can have different characteristics. You can set the characteristicsof dome modules by means of parameter assignment.The information contained in this section refers only to the programmable digitalmodules:• Digital input module SM 321; DI 16 x DC 24 V with process and diagnosisalarm, synchronous; (6ES7321-7BH01-0AB0)• Digital input module SM 322; DO 8 x VDC 24/0.5 A with diagnostic interrupt(6ES7322-8BF00-0AB0)• Digital output module SM 322; DO 8 x 120/230 VAC /2A ISOL(6ES7322-5FF00-0AB0)• Relay output module SM 322; DO 8 x Rel. 230 VAC /5A(6ES7322-5HF00-0AB0)• Digital Input/Output Module SM 327; DI 8/DX 8 x VDC 24/0.5 A(6ES7327-1BH00-0AB0)Tools for parameter assignmentYou assign parameters to digital modules in STEP 7. You must perform parameterassignment in STOP mode of the CPU.When you have set all the parameters, download the parameters from theprogramming device to the CPU. On a transition from STOP to RUN mode, theCPU then transfers the parameters to the individual digital modules.Static and dynamic parametersThe parameters are divided into static and dynamic parameters.Set the static parameters in STOP mode of the CPU, as described above.You can also change the dynamic parameters in the running user program in an S7logic control using SFC. Note, however, that after a change from RUN STOP,STOP RUN of the CPU, the parameters set in STEP 7 apply again. You will finda description of the parameter assignment of modules in the user program inAppendix A.Parameter Settable with CPU Operating StateStatic PG (STEP 7 HW CONFIG) STOPDynamic PG (STEP 7 HW CONFIG) STOPSFC 55 in the user program RUNProgrammable Logic Controllers S7-300 Module DataA5E00105505-033-11

Digital ModulesParameters of the digital modulesThe settable parameters are listed in the special section on the module.3.4 Diagnostics of the Digital ModulesIntroductionThe information contained in this section refers only to the digital modules withdiagnostics capability. For the S7-300, these modules are as follows:• Digital input module SM 321; DI 16 x DC 24 V with hardware and diagnosticinterrupts, clocked; (6ES7321-7BH01-0AB0)• Digital Output Module SM 322; DO 16 x 24/48 VUC(6ES7322-5GH00-0AB0)• Digital Output Module SM 322; DO 8 x DC 24 V/0.5 A with diagnostic interrupt(6ES7322-8BF00-0AB0)• Digital output module SM 322; DO 8 x 120/230 VAC /2A ISOL(6ES7322-5FF00-0AB0)• Relay output module SM 322; DO 8 x Rel. 230 VAC /5A(6ES7322-5HF00-0AB0)Programmable and non-programmable diagnostic messagesIn diagnostics, we make a distinction between programmable andnon-programmable diagnostic messages.You obtain programmable diagnostic messages only if you have enableddiagnostics by parameter assignment. You perform parameter assignment in the“Diagnostics” parameter field in STEP 7.Non-programmable diagnostic messages are always made available by the digitalmodule irrespective of diagnostics being enabled.Actions following diagnostic message in STEP 7Each diagnostic message leads to the following actions:• The diagnostic message is entered in the diagnosis of the digital module andforwarded to the CPU.• The SF LED on the digital module lights.• If you have programmed “Enable Diagnostic Interrupt” in STEP 7, a diagnosticinterrupt is triggered and OB 82 is called.3-12Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Digital ModulesReading out diagnostic messagesYou can read out detailed diagnostic messages by means of SFCs in the userprogram (refer to the Appendix “Diagnostic Data of Signal Modules”).You can view the cause of the error in STEP 7, in the module diagnosis (refer toonline Help for STEP 7).Diagnostic message by means of SF LEDThe digital modules with diagnostics capability indicate errors for you by means oftheir SF LED (group error LED). The SF LED lights as soon as a diagnosticmessage is triggered by the digital module. It goes out when all errors have beenrectified.The group fault (SF) LED also lights up in case of external errors (short circuit ofsensor supply), independent of the operating status of the CPU (if power is on).Diagnostic messages interrupt processing by the digital modulesYou will find the diagnostic messages with their possible causes and remedialaction, together with a description of possible interrupts in the specific section onthe module.3.5 Digital Input Module SM 321; DI 32 x VDC 24;(6ES7321-1BL00-0AA0)Order number: “Standard module”6ES7321-1BL00-0AA0Order number: SIPLUS S7-300 Module6AG1321-1BL00-2AA0CharacteristicsThe digital input module SM 321; DI 32 x 24 VDC has the following salientfeatures:• 32 inputs, isolated in groups of 16• 24 VDC rated input voltage• Suitable for switches and two / three / four-wire BEROs (proximity switches).Programmable Logic Controllers S7-300 Module DataA5E00105505-033-13

Digital Modules3.9.1 SynchronicityCharacteristicsReproducible (i.e. same length) reaction times are achieved for the SIMATIC withan equidistant DP bus cycle and synchronization of the following free runningsingle cycles:• Free running of the user program. The length of the cycle time can vary due toacyclic program branches.• Free running, variable DP cycle at the PROFIBUS subnetwork• Free running cycle at the DP slave back plane bus.• Free running cycle during signal processing and conversion in the electronicmodules of the DP slave.In the case of equidistance the DP cycle runs in phase and with the same length.The procedure levels of a CPU (OB 61 to OB 64) and the synchronous peripheralare synchronized in this cycle. The E/A data are therefore transferred at definedand consistent time intervals (clock synchronicity).Requirements• The DP-Master and DP-Slave must support the synchronicity.

Digital ModulesNoteA prerequisite for detecting the errors indicated by programmable diagnosticmessages is that you have assigned parameters to the digital module accordinglyin STEP 7.Behavior upon failure of the supply voltageA failure of the supply voltage of the SM 321; DI 16 x 24 DC is always indicated bythe SF LED on the module. Furthermore, this information is made available on themodule.The input value is initially held for 20 to 40 ms before the 0 signal is transferred tothe CPU. Supply voltage dips < 20 ms do not modify the process value (refer toTable 3-11).Triggering of the diagnostic interrupt depends on the parameter assignment (seeSection 3.9.4).Failure of the supply voltage with redundant encoder incoming supplyNoteIf an external redundant source is applied simultaneously to the sensor supply(Vs), a failure in the internal sensor supply causes a failure of the internal and/orexternal sensor supply and/or a blown fuse to be indicated instead of a regularsensor supply failure.Short-circuit of sensor supply VsIrrespective of the parameter assignment, the corresponding Vs LED goes out if ashort-circuit of the encoder supply Vs occurs.3-30Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Digital Modules3.9.4 Interrupts of the SM 321; DI 16 x 24 VDCIntroductionThis section describes the SM 321; DI 16 x 24 VDC with regard to its interruptbehavior. The following interrupts exist:• Diagnostic interrupt• Hardware interruptThe OBs and SFCs mentioned below can be found in the online Help for STEP 7,where they are described in greater detail.Enabling interruptsThe interrupts are not preset – in other words, they are inhibited withoutappropriate parameter assignment. Assign parameters to the Interrupt Enable inSTEP 7 (refer to Section 3.9.2).Diagnostic interruptIf you have enabled diagnostic interrupts, then active error events (initialoccurrence of the error) and departing error events (message aftertroubleshooting) are reported by means of an interrupt.The CPU interrupts the execution of the user program and processes thediagnostic interrupt block (OB 82).In the user program, you can call SFC 51 or SFC 59 in OB 82 to obtain moredetailed diagnostic information from the module.The diagnostic information is consistent until such time as OB 82 is exited. WhenOB 82 is exited, the diagnostic interrupt is acknowledged on the module.Hardware interruptThe SM 321; DI 16 x 24 VDC can trigger a hardware interrupt for every channelgroup with a rising or falling edge, or both, of a signal status change.Perform parameter assignment one channel group at a time. It can be modified atany time (in RUN mode using the user program).Pending hardware interrupts trigger hardware interrupt processing in the CPU(OB 40). The CPU interrupts the execution of the user program or of the priorityclasses with low priority.You can set in the user program of the hardware interrupt OB (OB 40) how theprogrammable logic controller has to react to an edge change. When the hardwareinterrupt OB is exited, the hardware interrupt is acknowledged on the module.The module can buffer one interrupt per channel. If no higher priority run-timelevels are waiting to be processed, the buffered interrupts (of all modules) areserviced one after the other by the CPU according to the order in which theyoccurred.3-32Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Digital ModulesHardware interrupt lostIn an interrupt has been buffered for a channel and another interrupt occurs on thatchannel before it has been processed by the CPU, a diagnostic interrupt “hardwareinterrupt lost” is triggered.More interrupts on this channel are not acquired until processing of the interruptbuffered on this channel has been executed.Interrupt-triggering channelsThe channel triggered by the hardware interrupt is entered in the start informationof the OB 40 in the OB40_POINT_ADDR variable.

Use STEP 7 to assign parameters for enablinginterrupts.Diagnostic InterruptIf you have enabled diagnostic interrupts, then incoming active error events (initialoccurrence of the error) and departing error events (message aftertroubleshooting) are reported by means of interrupts.The CPU interrupts execution of the user program and processes the diagnosticinterrupt block (OB 82).In the user program, you can call SFC 51 or SFC 59 in OB 82 to obtain moredetailed diagnostic information from the module.The diagnostic information is consistent until such time as OB 82 is exited. WhenOB 82 is exited, the diagnostic interrupt is acknowledged on the module.Programmable Logic Controllers S7-300 Module DataA5E00105505-033-105

Analog Modules4.3 Analog Value RepresentationIntroductionThis section describes the analog values for all the measuring ranges and outputranges which you can use with the analog modules.Converting Analog ValuesThe CPU processes the analog values in binary form only.Analog input modules convert the analog process signal into digital form.Analog output modules convert the digital output value into an analog signal.Analog value representation with 16-bit resolutionThe digitized analog value is the same for both input and output values having thesame nominal range. The analog values are represented as a fixed-point numberin two’s complement. The resulting assignment is as follows:Bits 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0Value of bits 2 15 2 14 2 13 2 12 2 11 2 10 2 9 2 8 2 7 2 6 2 5 2 4 2 3 2 2 2 1 2 0SignThe sign of the analog value is always contained in bit number 15:• “0” • “1” Resolution less than 16 bitsIf the resolution of an analog module has fewer than 16 bits, the analog value isstored left-justified on the module. The lower-order bit positions not used arepadded with zeros (”0”).Programmable Logic Controllers S7-300 Module DataA5E00105505-034-9

Analog ModulesExampleIn the following example you can see how the positions not padded with “0” arewritten for low resolution.Table 4-6Example: Bit pattern of a 16-bit and a 13-bit analog valueResolutionAnalog valueBits 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 016-bit analog value 0 1 0 0 0 1 1 0 0 1 1 1 0 0 1 113-bit analog value 0 1 0 0 0 1 1 0 0 1 1 1 0 0 0 04.3.1 Analog Value Representation for Analog Input ChannelsIntroductionThe tables in this chapter contain the measured value representations for thevarious measuring ranges of the analog input modules. The values in the tablesapply to all modules with the corresponding measuring ranges.Notes for readers of the tablesTables 4-8 to 4-9 contain the binary representation of the measured values.Since the binary representation of the measured values is always the same,starting at 4-10 these tables only contain the measured values and the units.4-10Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesMeasured-value resolutionThe resolution of the analog values may differ, depending on the analog moduleand its parameterization. With resolutions < 15 bits, the bits indicated by “x” are setto “0”.Note: This resolution does not apply to temperature values.

Analog Modules4.3.2 Analog Value Representation for Analog Output ChannelsIntroductionThe tables in this chapter contain the analog value representation for outputchannels of the analog output modules. The values in the tables apply to allmodules with the corresponding output ranges.Notes for readers of the tablesTables 4-32 to 4-33 contain the binary representation of the output values.Since the binary representation of the output values is always the same, starting at4-34 these tables only contain the output ranges and the units.Output ranges for the SM 334; AI 4/AO 28/8 bitsThe analog input/output module SM 334; AI 4/AO 2 x 8/8 bits has output rangesfrom 0 to 10 V and from 0 to 20 mA. Unlike the other analog modules, the SM 334has a lower resolution, however. Please not that the SM 334; AI 4/AO 2 x 8/8 bitswith product status 1 does not have overranges.Binary representation of the output rangesThe output ranges shown in Tables 4-32 to 4-33 are defined in two’s complementrepresentation:4-24Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.4 Setting the Measuring Method and Measuring Ranges ofAnalog Input ChannelsTwo proceduresThere are two procedures for setting the measuring method and the measuringranges of the analog input channels of the analog modules:• With measuring range module and STEP 7• By means of wiring the analog input channel and STEP 7Which of these two methods is used for the individual analog modules depends onthe module and is described in detail in the specific module sections.The procedure for setting the measuring method and measuring range of themodule in STEP 7 is described in Section 4.7.The following section describes how you set the measuring method and themeasuring range by means of measuring range modules.Setting the Measuring Method and the Measuring Ranges with Measuring RangeModulesIf the analog modules haves measuring range modules, they are supplied with themeasuring range modules plugged in.If necessary, the measuring range modules must be replugged to change themeasuring method and the measuring range.NoteMake sure that the measuring range modules are on the side of the analog inputmodule.Before installing the analog input module, therefore, check whether the measuringrange modules have to be set to another measuring method and anothermeasuring range.Possible settings for the measuring range modulesThe measuring range modules can be set to the following positions: “A”, “B”, “C” and“D”.Which measuring range module positions you must select for the individualmeasuring methods and measuring ranges is described in detail in the specificmodule section.The settings for the various types of measurement and measuring ranges are alsoprinted on the analog module.4-28Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesBehavior on failure of the supply voltageFailure of the supply voltage of the analog modules is always indicated by the SFLED on the module. Furthermore, this information is made available on the module(entry in diagnostic buffer).Triggering of the diagnostic interrupt depends on the parameter assignment (seeSection 4.7).4.5.2 Effect of Range of Values of the Analog ValuesEffect of errors on analog modules with diagnostics capabilityAny errors that occur can lead to a diagnostics entry and a diagnostic interrupt withanalog modules with diagnostics capability and corresponding parameterassignment. You will find the errors that might be involved in Section 4.16.Effect of range of values on the analog input moduleThe behavior of the analog modules depends on where the input values lie withinthe range of values.Table 4-39 Behavior of the Analog Input Modules as a Function of the Position of theAnalog Value within the Range of ValuesMeasuredValue InRated rangeOverrange/underrangeInput Value SF LED Diagnostics InterruptMeasuredvalueMeasuredvalue– – –– – –Overflow 7FFF H Flashes 1) Entered 1) Diagnosticinterrupt 1)Underflow 8000 H Flashes 1) Entered 1) Diagnosticinterrupt 1)Beyond theprogrammedlimitMeasuredvalue– – Hardwareinterrupt 1)1) Only for modules with diagnostics capability and depending on parameter assignment4-32Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.5.3 Effect of Operational Limit and Basic Error LimitOperational limitThe operational limit is the measuring error or output error of the analog moduleover the entire temperature range authorized for the module, referred to the ratedrange of the module.Basic error limitThe basic error limit is the operational limit at 25 °C, referred to the rated range ofthe module.NoteThe percentage details of operational and basic error limits in the technicalspecifications of the module always refer to the highest possible input and outputvalue in the rated range of the module.Example of determination of the output error of a moduleAn analog output module SM 332; AO 4 x 12 bits is being used for voltage output.The output range from “0 to 10 V” is being used. The module is operating at anambient temperature of 30 °C. Thus the operational limit applies. The technicalspecifications of the module state:• Operational limit for voltage output: 0.5 %An output error, therefore, of 0.05 V (0.5% of 10 V) over the whole rated rangeof the module must be expected.This means that with an actual voltage of, say, 1 V, a value in the range from 0.95V to 1.05 V is output by the module. The relative error is 5 % in this case.The figure below shows for the example how the relative error becomesincreasingly less the more the output value approximates to the end of the ratedrange of 10 V.0.05 V( 5 %)0.05 V( 0.625 %)0.05 V( 0.5 %*)Output Value–1 V 0 V 1 V8 V 10 V* Operational limitFigure 4-3 Example of the Relative Error of an Analog Output Module4-34Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.6 Conversion, Cycle, Setting and Response Time of AnalogModulesConversion time of analog input channelsThe conversion time consists of a basic conversion time and additional processingtimes of the module for:• Resistance test• Wire-break monitoringThe basic conversion time depends directly on the conversion method of theanalog input channel (integrating method, instantaneous value conversion).In the case of integrating conversion methods, the integration time has a directinfluence on the conversion time. The integration time depends on the interferencefrequency suppression that you set in STEP 7 (refer to Section 4.7.1).For the basic conversion times and additional processing times of the differentanalog modules refer to the technical specifications of the module concerned,starting at Section 4.18.Scan time of analog input channelsAnalog-to-digital conversion and the transfer of the digitized measured values tothe memory and/or to the bus backplane are performed sequentially – in otherwords, the analog input channels are converted one after the other. The scan time– in other words, the time elapsing until an analog input value is again converted, isthe sum of the conversion times of all activated analog input channels of theanalog input module.The following figure illustrates the components of the scan time for an n-channelanalog module.Conversion time,channel 1Conversion time,channel 2Scan timeConversion time,channel nFigure 4-4Scan time of an analog input or output moduleProgrammable Logic Controllers S7-300 Module DataA5E00105505-034-35

Analog ModulesConversion and scan times for analog input channels in channel groupsWhen the analog input channels are grouped in channel groups, you must take intoaccount the conversion time channel group by channel group.ExampleTwo analog input channels of the analog input module SM 331; AI 212 bits arecombined to form a channel group. You must therefore grade the scan time insteps of 2.Setting smoothing of analog valuesYou can set the smoothing of the analog values in STEP 7 for some analog inputmodules.Using smoothingSmoothing of analog values ensures a stable analog signal for further processing.It makes sense to smooth the analog values with slow variations of measuredvalues – for example, with temperature measurements.Smoothing principleThe measured values are smoothed by digital filtering. Smoothing is accomplishedby the module calculating average values from a defined number of converted(digitized) analog values.The user assigns parameters to smoothing at not more than four levels (none, low,average, high). The level determines the number of analog signals used foraveraging.The higher the smoothing level chosen, the more stable is the smoothed analogvalue and the longer it takes until the smoothed analog signal is applied after astep response (refer to the following example).4-36Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesExampleThe following figure shows the number of module cycles for a step response afterwhich the smoothed analog value is approximately 100% applied, as a function ofthe smoothing that has been set. The figure applies to every change of signal atthe analog input.Signal variationin percent100Step response for any analog input signal6350Smoothing:Figure 4-5050 100 150 200low:Module cyclesaverage:high:Example of the Influence of Smoothing on the Step ResponseAdditional information on smoothingRefer to the specific section on the analog input module (from Section 4.22) todetermine whether smoothing can be set for the specific module and for anyspecial features that have to be taken into account.Conversion time of the analog output channelsThe conversion time of the analog output channels comprises the transfer of thedigitized output values from the internal memory and the digital-to-analogconversion.Scan time of analog output channelsThe analog output channels are converted sequentially – in other words, theanalog output channels are converted one after the other.The scan time – in other words, the time elapsing until an analog output value isagain converted, is the sum of the conversion times of all activated analog outputchannels (refer to 4-4).Programmable Logic Controllers S7-300 Module DataA5E00105505-034-37

Analog ModulesTipYou should disable any analog channels that are not being used to reduce the scantime in STEP 7.Overview of the settling time and response time of the analog output modulest At Zt Et 1 t 2t 3t A = Response timet Z = Scan time corresponds to n conversion time (n = activated channels)t E = Settling timet 1 = New digitized output value is presentt 2 = Output value transferred and convertedt 3 = Specified output value reachedFigure 4-6Settling and Response times of the Analog Output ChannelsSettling timeThe settling time (t 2 to t 3 ) – in other words, the time elapsing from application theconverted value until the specified value is reached at the analog output – isload-dependent. A distinction is made between resistive, capacitive and inductiveloads.For the settling times of the different analog output modules as a function of loadrefer to the technical specifications of the module concerned, starting at Section4.28.Response timeThe response time (t 1 to t 3 ) – in other words, the time elapsing from application ofthe digital output values in the internal memory until the specified value is reachedat the analog output – in a worst case scenario is the sum of the scan time and thesettling time.You have a worst case situation, if, shortly prior to the transfer of a new outputvalue, the analog channel has been converted and is not converted again until allother channels are converted (scan time).4-38Programmable Logic Controllers S7-300 Module DataA5E00105505-03

You can set the characteristicsof the modules by means of parameter assignment.Tools for parameter assignmentYou assign parameters to analog modules with STEP 7. You must performparameter assignment in STOP mode of the CPU.When you have set all the parameters, download the parameters from theprogramming device to the CPU. On a transition from STOP to RUN mode, theCPU then transfers the parameters to the individual analog modules.In addition, if necessary you must place the measuring range modules of themodule in the necessary position (refer to Section 4.4).Static and dynamic parametersThe parameters are divided into static and dynamic parameters.Set the static parameters in STOP mode of the CPU, as described above.You can similarly modify the dynamic parameters in the current user program bymeans of SFCs. Note, however, that after a change from RUN STOP, STOP RUN of the CPU, the parameters set in STEP 7 apply again. You will find adescription of the parameter assignment of modules in the user program inAppendix A.Parameter Settable with CPU OperatingStateStatic PG (STEP 7 HW CONFIG) STOPDynamic PG (STEP 7 HW CONFIG) STOPSFC 55 in the user programRUNProgrammable Logic Controllers S7-300 Module DataA5E00105505-034-39

Analog Modules4.8 Connecting Sensors to Analog InputsIntroductionYou can connect different sensors to the analog input modules depending on themeasuring method; voltage and current sensors, and resistors.This section contains general information that is generally applicable to all theconnection options for sensors described in the sections that follow.Cables for analog signalsTo reduce electrical interference, you should use twisted-pair shielded cables forthe analog signals. The shield of the analog signal cables should be grounded atboth cable ends.If there are potential differences between the cable ends, an equipotential bondingcurrent can flow over the shield, which leads to an interference of the analogsignals. In such a case, you should ground the shield at one end of the cable only.Isolated analog input modulesIn the case of isolated analog input modules, there is no electrical connectionbetween the reference point of the measuring circuit M ANA and the M terminal ofthe CPU.You must use isolated analog input modules if a potential difference U ISO canoccur between the reference point of the measuring circuit M ANA and theM terminal of the CPU. An equipotential bonding conductor between the M ANAterminal and the M terminal of the CPU ensures that U ISO does not exceed thepermitted value.Non-isolated analog input modulesIn the case of the non-isolated analog input modules, you must establish aconnection between the reference point of the measuring circuit M ANA and the Mterminal of the CPU or IM 153. To do so, connect the M ANA terminal with the Mterminal of the CPU or IM 153. A potential difference between M ANA and the Mterminal of the CPU or IM 153 can result in corruption of the analog signal.Limited potential difference UCMOnly a limited potential difference U CM (common mode voltage) may occurbetween the measuring lines M– of the input channels and the reference point ofthe measuring circuit M ANA . In order to prevent the permissible value from beingexceeded, you must take different actions, described below, depending on thepotential connection of the sensors.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-45

It is important that the connected constantcurrent cables are directly connected to the resistance thermometer/resistor.Measurements with four-conductor or three-conductor connections supply a moreprecise measuring result due to compensation than measurements with atwo-conductor connection.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-53

Analog Modules4.12 Connecting ThermocouplesDesign of thermocouplesA thermocouple consists of a pair of sensors and the necessary installation andconnecting parts. The thermocouple consists of two wires of dissimilar metals ormetal alloys soldered or welded together at the ends.There are different types of thermocouple, depending on the composition of thematerial used – for example, K, J, N thermocouples. The measuring principle of allthermocouples is the same, irrespective of their type.Measuring junctionThermocouple with positive or negative limbsConnecting pointCompensating leadsReference junctionLeads° CPoint at which thermo-e. m. f. is measuredFigure 4-22Design of ThermocouplesPrinciple of Operation of ThermocouplesIf the measuring point is subjected to a temperature different from that of the freeends of the thermocouple (point of connection), a voltage, the thermo emf, occursat the free ends. The magnitude of the thermo-e.m.f. generated depends on thedifference between the temperature at the measuring junction and the temperatureat the free ends, as well as on the material combination used for the thermocouple.Since a thermocouple always measures a temperature difference, the free endsmust be kept at a known temperature at a reference junction in order to determinethe temperature of the measuring junction.The thermocouples can be extended from their point of connection to the referencejunction by means of compensating wires. These compensating wires consist ofthe same material as the thermocouple wires. The supply leads are copper wire.Note: Make sure these wires are connected with the correct polarity, otherwisethere will be considerable measuring errors.4-58Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesCompensation of the reference junction temperatureYou can compensate for the effects of temperature fluctuations at the referencejunction by means of compensating leads.There are several options for you to choose from for acquiring the referencejunction temperature in order to obtain an absolute temperature value from thedifference in temperature between the reference junction and measuring point.You can use internal or external compensation, depending on where you want thereference junction to be.Table 4-44 Options for Compensation of the Reference Junction TemperatureNo compensationOptionInternal compensation(refer to Figure 4-23 for connection)External compensation with compensatingbox in the leads of an individualthermocouple (refer to Figures 4-24 and4-25 for its connection)Only for SM 331; AI 8 x TC:External compensation with resistancethermometer for acquisition of the referencejunction temperature(refer to Figure 4-26 and 4-27forconnection)ExplanationIf you want to acquire only the difference in temperaturebetween the measuring point and the reference junction.If you employ internal compensation, the internaltemperature (thermocouple internal comparison) of themodule is used for comparison purposes.You have already acquired and compensated thereference junction temperature (thermocouple externalcomparison) using a compensating box, which you havelooped into an individual thermocouple.No further processing is necessary owing to the module.You can acquire the reference temperature by means of aresistance thermometer (platinum or nickel) and have itcalculated by the module for any thermocouple.Theory of operation of internal compensationWith internal compensation, you can establish the reference point across theterminals of the analog input modules. In this case, you must run thecompensating lines right up to the analog module. The internal temperature sensoracquires the temperature of the module and supplies a compensation voltage.Note that internal compensation is not as accurate as external compensation.Theory of operation of external compensation with compensating boxIf you employ external compensation, the temperature of the reference junction ofthe thermocouples is taken into account via a compensating box, for example.The compensating box contains a bridge circuit calibrated for a definite referencejunction temperature. The reference junction is formed by the connections for theends of the thermocouple’s compensating leads.If the actual temperature deviates from the compensating temperature, thetemperature-sensitive bridge resistance changes. This results in a positive ornegative compensating voltage, which is added to the thermo-e.m.f.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-59

The cablesQ V and S+ and M and S–, respectively, are to be twisted together. This reduces theinterference. Ground the screen of the analog cables at both ends of the cables.If there are potential differences between the cable ends, an equipotential bondingcurrent, which can flow over the shield, can cause interference of the analogsignals. In such a case, you should ground the shield at one end of the cable only.Isolated Analog Output ModulesWith the isolated analog output modules there is no electrical connection betweenthe reference point of the measuring circuit M ANA and the M terminal of the CPU.You must use isolated analog output modules if a potential difference U ISO canoccur between the reference point of the measuring circuit M ANA and theM terminal of the CPU. By means of a equipotential bonding conductor betweenthe M ANA terminal and the M terminal of the CPU, make sure that U ISO does notexceed the permitted value.Non-Isolated Analog Output ModulesWith the non-isolated analog output modules, you must establish a connectionbetween the reference point of the measuring circuit M ANA and the M terminal ofthe CPU. Therefore, connect the M ANA terminal with the M terminal of the CPU. Apotential difference between M ANA and the M terminal of the CPU can lead to acorruption of the analog signal.4-66Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesConnecting Loads to a Voltage Output of an Isolated Module over aFour-Conductor ConnectionA high accuracy at the load can be achieved through the four-conductorconnection. You must therefore connect the sensor leads (S– and S+) directly tothe load. The voltage is thus measured and corrected directly at the load.Interferences or a voltage drop can result in a potential difference between thesensor lead S– and the reference circuit of the analog circuit M ANA . This potentialdifference must not exceed the permissible value.

You perform parameter assignment in the“Diagnostics” parameter field in STEP 7 (refer to Section 4.7).Non-programmable diagnostic messages are always made available by the analogmodule irrespective of diagnostics being enabled.Actions following diagnostic message in STEP 7Each diagnostic message leads to the following actions:• The diagnostic message is entered in the diagnosis of the analog module andforwarded to the CPU.• The error LED on the analog module lights.• If you have programmed “Enable Diagnostic Interrupt” with STEP 7, adiagnostic interrupt is triggered and OB 82 is called (refer to Section 4.17).Programmable Logic Controllers S7-300 Module DataA5E00105505-034-71

Analog ModulesReading out diagnostic messagesYou can read out detailed diagnostic messages by means of SFCs in the userprogram (refer to the Appendix “Diagnostic Data of Signal Modules”).You can view the cause of the error in STEP 7, in the module diagnosis (refer toonline Help for STEP 7).Diagnostic message in the measured value of analog input modulesEvery analog input module supplies the measured value 7FFF H irrespective of theparameter assignment when an error is detected. This measured value meanseither Overflow, Malfunction or a channel is disabled.Diagnostic message by means of SF LEDEvery analog module indicates errors for you by means of your SF LED (grouperror LED). The SF LED lights as soon as a diagnostic message is triggered by theanalog module. It goes out when all errors have been rectified.Diagnostic messages of the analog input modulesThe table below gives an overview of the diagnostic messages for the analog inputmodules.Table 4-46 Diagnostic Messages of the Analog Input ModulesDiagnostics Message LED DiagnosticsEffective forParameters canbe assignedExternal auxiliary supply missing SF Module NoConfiguring/parameter assignmenterrorSFChannelCommon-mode error SF Channel YesWire-break SF Channel YesUnderflow SF Channel YesOverflow SF Channel YesYes4-72Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.17 Interrupts of the Analog ModulesIntroductionIn this Section, the interrupt behavior of the analog modules is described. Thefollowing interrupts exist:• Diagnostic interrupt• Hardware interruptNote that not all analog modules have interrupt capability or they are only capableof a subset of the interrupts described here Refer to the technical specifications ofthe modules, starting at Section 4.18, to determine which analog modules haveinterrupt capability.The OBs and SFCs mentioned below can be found in the online Help for STEP 7,where they are described in greater detail.Enabling interruptsThe interrupts are not preset – in other words, they are inhibited withoutappropriate parameter assignment. Assign parameters to the Interrupt Enable inSTEP 7 (refer to Section 4.7).Diagnostic interruptIf you have enabled diagnostic interrupts, then active error events (initialoccurrence of the error) and departing error events (message aftertroubleshooting) are reported by means of an interrupt.The CPU interrupts the execution of the user program and processes thediagnostic interrupt block (OB 82).In the user program, you can call SFC 51 or SFC 59 in OB 82 to obtain moredetailed diagnostic information from the module.The diagnostic information is consistent until such time as OB 82 is exited. WhenOB 82 is exited, the diagnostic interrupt is acknowledged on the module.Hardware interrupt with trigger “Upper or lower limit exceeded”Define a working range by setting parameters for an upper and lower limit value. Ifthe process signal (for example, the temperature) leaves this working range, themodule triggers a hardware interrupt, provided the interrupt is enabled.The CPU interrupts execution of the user program and processes the hardwareinterrupt block (OB 40).In the user program of OB 40, you can set how the programmable logic controlleris required to react to a limit value being surpassed or not being reached.When OB 40 is exited, the hardware interrupt is acknowledged on the module.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-75

Analog ModulesNoteNote that a hardware interrupt is not triggered if you have set the upper limit abovethe overrange or the lower limit below the underrange.Structure of the start information tag OB40_POINT_ADDR of OB 40The limit values exceeded by the different channels are entered in the startinformation of OB 40 in the tag OB40_POINT_ADDR.

The module processes the channels oneafter the other. After all the measured values have been converted, the module ofthe CPU reports by means of an interrupt that there are new measured values onall channels.You can use the interrupt to load the currently converted analog values.4-76Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesWiring of the module for measuring currentCurrent measurements are made by paralleling a channel’s voltage input terminalswith its respective current sense resistor. This is accomplished by jumpering thechannels input terminals to the adjacent terminals on the field connector.Example: To configure channel 0 for current mode, you must jumper terminal 22 to2 and terminal 23 to 3.The channel being configured for current measurements must be paired with thesense resistor connected to the channel’s adjacent terminals in order to achievethe specified accuracy.Technical specifications of the SM 331; AI 8 x 16 bitsDimensions and WeightAnalog value generationDimensions W x H x D(in millimeters)WeightSupports clocked operation40 x 125 x 117Approx. 272 gData for Specific ModuleNumber of inputs 8NoLength of cable• Shielded max. 200 mVoltages, Currents, PotentialsIsolation• Between channels andbackplane busPermitted potential difference• Between the inputs(ECM)• Between M ANA andM internal (U ISO )Insulation tested withYes50 VDC, 35 VAC75 VDC / 60 VAC500 VDCCurrent consumption• From the backplane bus max. 130 mAPower dissipation of themoduletypically 0.6 WMeasuring principleIntegration time/conversiontime/ resolution (per channel)• Parameters can beassigned• Integration time inmilliseconds• Basic conversion timeper channel groupwhen more than onechannel group isactive• Channel conversiontime per channelgroup if only channelgroup 0 or 1 isenabledChannel integration time(1/f1)in ms• Resolution includingsign• Suppression ofinterference voltage forinterference frequency f1in HertzBasic execution time of themodule, in ms (all channelsenabled)IntegratingYes10 16.7 20 10035 55 65 30510 16.7 20 10010 16.7 20 10015 bits + sign100 60 50 10140 220 260 1220Programmable Logic Controllers S7-300 Module DataA5E00105505-034-79

Analog ModulesChannel groupsThe channels of the SM 331; AI 8 x 16 bits are arranged in four groups of two. Youcan only ever assign parameters to one channel group.The table below shows which channels are parameterized as a channel group ineach case. You will need the channel group number to set the parameters in theuser program with an SFC.Table 4-51 Assignment of Channels of the SM 331; AI 8 x 16 bits to Channel GroupsChannels ...Channel 0Channel 1Channel 2Channel 3Channel 4Channel 5Channel 6Channel 7... form one Channel Group eachChannel group 0Channel group 1Channel group 2Channel group 3High Speed Update ModeIn the high speed update mode, updates for the two channels in the group occurthree times faster than with multiple channel groups enabled.Example: If channels 0 and 1 are enabled with 2.5 ms filtering, data updates forboth channels will be available to the PLC every 10 msec. (For other filter settings,the filter setting equals the update rate.)The high speed update mode is only available when both channels are enabled onchannel group 0 or 1, in other words, the “measuring method” parameter is set.However, only channel group 0 or only channel 1 (in other words, not bothtogether) must be enabled.Special characteristic of channel groups for hardware interruptsYou can set hardware interrupts in STEP 7 for the channel groups 0 and 1. Note,however, that a hardware interrupt is set only for the first channel in the channelgroup in each case – in other words, for channel 0 or channel 2DiagnosticsYou will find the diagnostic messages that are grouped under the “group diagnosis”parameter in Table 4-46, on page 4-72.4-82Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.18.2 Measuring Methods and Measuring Ranges of the SM 331;AI 8 x 16 bitsMeasuring MethodsYou can set the following measuring methods for the input channels:• Voltage measurement• Current measurementYou perform the setting with the “measuring method” parameter in STEP 7.Unused ChannelsSet the “measuring method” parameter for unused channels to “disabled”. In thisway you shorten the scan time of the module.Since configured inputs can remain unused because of the channel groupgeneration, you must take note of the following special characteristics of theseinputs to enable the diagnostic functions on the used channels.• Measuring range 1 to 5 V: Connect the unused input in parallel with a usedinput of the same channel group.• Current measurement 4 to 20 mA: Connect the unused input in series with aninput of the same channel group. Ensure that a current sense resistor isconnected for each active and unused channel.• Other ranges: Short the positive to the negative input of the channel.Measuring rangesThe measuring ranges are set with the “measuring range” parameter in STEP 7.Table 4-52 Measuring Ranges of the SM 331; AI 8 x 16 bitsMethod Selected Measuring Range DescriptionU: Voltage ±5 V1 to 5 V±10 V4DMU: Current (4-wiretransmitter)from 0 to 20 mA±20 mAfrom 4 to 20 mAYou will find the digitized analog values inSection 4.3.1 in the voltage measuringrangeYou will find the digitized analog values inSection 4.3.1 in the current measuringrangeProgrammable Logic Controllers S7-300 Module DataA5E00105505-034-83

Analog ModulesDefault SettingsThe default settings of the module are “voltage” for the measuring method “ and 10 V” for the measuring range. You can use this combination of measuringmethod and measuring range without parameterizing the SM 331; AI 8 x 16 bits inSTEP 7.Measuring errors with common-mode voltagesThe SM 331; AI 8 x 16 bits can make measurements in the presence of AC or DCcommon mode voltage.For AC common mode voltages at multiples of the filter frequency setting, thesuppression of interference is accomplished by the integration period of the A/Dconverter and by the common mode suppression of the input amplifiers. For ACcommon mode voltages < 35 V RMS , the suppression ratio of > 100 dB results innegligible measurement error.For DC common mode voltages, only the interference suppression of the inputamplifier stage is available to minimize the effect of the common mode voltage.Therefore, some accuracy degradation occurs in proportion to the common modevoltage. The worst case error occurs with 50 VDC between one channel and theother seven channels. The calculated worst case error is 0.7 % at 0 to 60 °C, andmeasured error is typically ≤ 0.1% at 25 °C.Special characteristic of parameter assignment to upper and lower limit valuesThe parameterizable limit values (triggers for hardware interrupt) differ for theSM 331; AI 8 x 16 bits from the range of values contained in Table 4-50.The reason for this is that numerical methods in the module software for evaluatingthe process variables prevent values up to 32511 from being reported in somecases. The process input value at which a hardware interrupt for an underflow oroverflow occurs depends on the calibration factors for an individual channel andcan vary between the lower limits shown in the table below and the value 32511(7EFF H ).4-84Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.19.2 8-channel modeDescription of the module cycleIn 8-channel mode, the isolated analog input module SM 331; AI 8 x 16 bitsswitches between the two channels in each group. As the module contains fouranalog/digital converters (ADC), all four of the ADCs simultaneously convert forchannels 0, 2, 4 and 6. Once the even-numbered channels have been converted,all the ADCs simultaneously convert for the odd-numbered channels 1, 3, 5 and 7(see Figure 4-35).Start analog conversion(simultaneous)K0 K2 K4 K6Scan timeStart analog conversion(simultaneous)K1 K3 K5 K7Figure 4-358-channel mode cycle4-92Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesScan time of the moduleIn the 8-channel mode of the SM 331; AI 8 x 16 bits, the channel conversion timedepends on the selected interference frequency. When you set an interferencefrequency of 50 Hz, the channel conversion time including communication time is76 ms. When you set an interference frequency of 60 Hz, the channel conversiontime is 65 ms. When you set an interference frequency of 400 Hz, the channelconversion time is reduced to 16 ms. When you set an interference frequency of50, 60 and 400 Hz, the channel conversion time is 88 ms. The module must thenbe switched over to the other channel of the group by means of opto-MOS relays.Opto-MOS relays need 7 ms to switch and settle. Table 4-56 shows the scan timesof the module at certain interference frequencies.Table 4-56 Scan times in 8-channel modeInterference frequency(Hz)Channel scan time(ms)Module scan time(All channels)50 83 16660 72 144400 23 46400/60/50 95 1904.19.3 4-channel modeDescription of the module cycleIn 4-channel mode, the SM 331; AI 8 x 16 bits does not switch over between thechannels of the individual groups.

Analog ModulesScan time of the moduleIn 4-channel mode, the channel conversion time including communication time ofthe SM 331; AI 8 x 16 bits is 10 ms. As the module does not switch over betweenthe channels in a group, the channel scan time and the modulescan time are the same: 10 ms.4.19.4 Measuring Methods and Measuring Ranges of the SM 331;AI 8 x16 bitsMeasuring MethodsYou can set the following measuring methods for the input channels:• Voltage measurement• Current measurement (4-wire transmitter)You perform the setting with the “measuring method” parameter in STEP 7.Unused ChannelsSet the “measuring method” parameter for unused channels to “disabled”. In thisway you shorten the scan time of the module.Since configured inputs can remain unused because of the channel groupgeneration, you must take note of the following special characteristics of theseinputs to enable the diagnostic functions on the used channels.• Measuring range 1 to 5 V: Connect the unused input in parallel with a usedinput of the same channel group.• Current measurement, 4 to 20 mA: Connect the unused input in series withan input of the same channel group. Ensure that a current sense resistor isconnected for each active and unused channel.• Other ranges: Short the positive to the negative input of the channel.4-94Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesWire–break checkThe wire-break check is a module software function that is available for all thevoltage ranges and the current range of 4 to 20 mA.• With the ± 5 V, 1 to 5 V or ± 10 V measuring ranges and an enabled wire-breakcheck, the isolated analog input module enters a wire-break in the diagnosiswhen the process value achieves a positive full-scale deflection (32768). If youenabled the diagnostic interrupt during configuration, the analog input modulealso triggers a diagnostic interrupt.If the diagnostic interrupt has not been enabled, the illuminated SF display isthe only indication that there is a wire-break. You must then analyze thediagnosis bytes in the user program.• With a measuring range of 4 to 20 mA and an enabled wire-break check, theisolated analog input module enters wire-break in the diagnosis when theprocess value falls below 3.6 mA. If you enabled the diagnostic interrupt duringconfiguration, the analog input module also triggers a diagnostic interrupt.If the diagnostic interrupt has not been enabled, the illuminated SF display isthe only indication that there is a wire-break. You must then assess thediagnosis bytes in the user program.• If the wire-break check is not enabled, the isolated analog input module triggersa diagnostic interrupt if the limit value for underflow is not reached.Measuring rangesYou perform setting of the measuring ranges with the “measuring range” parameterin STEP 7.Table 4-57 Measuring ranges of the SM 331; AI 8 x 16 bitsVoltageMethod Selected Output Range DescriptionCurrent (4-wire transmitter) 5 VFrom 1 to 5 V 10 VFrom 0 to 20 mAFrom 4 to 20 mA 20 mAYou will find the digitalanalog values fromSection 4.3.1 in the voltageand current output rangesProgrammable Logic Controllers S7-300 Module DataA5E00105505-034-95

Analog ModulesShort circuit to M or LIf you short an input channel to M or L, the module does not suffer any damage.The channel continues to issue valid data; neither is a diagnosis reported.Overflow, underflow and hardware interrupt limitsThe diagnosis operating limits for overflow and underflow for some of themeasuring ranges differ from those given in section 4.3.1 of the manual. In somecases, numerical methods in the module software for evaluating the processvariables prevent values up to 32511 being signaled.Hardware interrupt limits must not be set to values greater than the smallestpossible limit value of the overflow or underflow operating limits for theend-of-scan-cycle interrupt in section 4.3.1.End-of-scan-cycle interruptBy enabling the end-of-scan-cycle interrupt, you can synchronize a process withthe conversion cycle of the module. The interrupt occurs when the conversion of allthe enabled channels is complete.Table 4-58 Content of the 4 bytes with additional information from OB40 during a hardwareinterrupt or an end-of-scan-cycle interruptContent of the 4 bytes withadditional information2 7 2 6 2 5 2 4 2 3 2 2 2 1 2 0 ByteSpecialanalogmarkers2 bits per channel to identify the rangeUpper limit exceededin channelLower limit exceededin channelEnd-of-scan-cycleevent7 6 5 4 3 2 1 0 07 6 5 4 3 2 1 0 1Unassigned bit 3X24-96Programmable Logic Controllers S7-300 Module DataA5E00105505-03

The length of the cycle time can vary due toacyclic program branching.• Free running, variable DP cycle at the PROFIBUS subnetwork• Free running cycle at the DP slave backplane bus.• Free running cycle during the signal processing and conversion in the electronicmodules of the DP slave.In the case of equidistance the DP cycle runs in phase and with the same length.In this cycle the processing levels of a CPU (OB 61 to OB 64) and thesynchronous peripheral are synchronized. The I/O data are therefore transferred atdefined and consistent time intervals (clock synchronicity).4-100Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesRequirements• The DP-Master and DP-Slave must support the synchronicity. They requireSTEP 7 from Version 5.2.Module filtering mode: SynchronicityIn synchronous operation the following conditions apply:Standard ModeFilter and processing time T WE between reading the current valueand loading it into the transfer buffer(the specified value for T WE applies, independent of the activation ofthe diagnosis)including an input delay time ofT DPminDiagnostic interruptmax. 625 s10 s3.5 msmax. 4 x T DPFast Mode (only possible with 6ES7331-7HF01-0AB0)Filter and processing time T WE between reading in the current valueand allocation in the transfer buffer(diagnosis not selectable)including an input delay time ofT DPminmax. 625 s10 s1 msNoteBy using “Fast Mode” the cycle of the DP system can be accelerated. However,this is at the expense of the diagnosis: The diagnosis is switched off in thisoperating mode.Together with the calculation and transfer times required on the IM 153, thespecified value for T WE results in the minimum settable value of HW Config of875 s for T i .The specified value for T DPmin is dependent on the extent of extension of the DPslave/IM 153: If there are a number of different plugged in modules, the slowestmodule determines the time T DPmin .NoteIn “Synchronous” mode, independent of the parameterization made in STEP 7, themodule always sets itself to “Integration time: no /parasitic frequency”. The“hardware interrupt” functionality is not possible in “Synchronous” mode.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-101

Analog ModulesCalculation of the filter and processing timeIndependent of the number parameterized channels, the same time conditions arealways valid.

Then channels 6...0 are converted sequentially at intervals of 52 s inthe same way. After a further internal processing time the result becomes availableto all converted channels at the backplane bus for collection by the CPU.Further informationFurther information on synchronicity can be found in the Online help of STEP 7, inthe manualLocal peripheral system ET 200M and in the manual Synchronicity.4-102Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesSpecial characteristic of channel groups with resistance measurementIf you use the resistance measurement method, there is only one channel perchannel group. The “2nd” channel of each group is used for current injection (I C ).The measured value is obtained by accessing the “1st” channel of the group. The“2nd” channel of the group has the default carry value “7FFF H ”.Special characteristic of channel groups for hardware interruptsYou can set hardware interrupts in STEP 7 for the channel groups 0 and 1. Note,however, that a hardware interrupt is set only for the first channel in the channelgroup in each case – in other words, for channel 0 or channel 2DiagnosticsYou will find the diagnostic messages that are grouped under the “group diagnosis”parameter in Table 4-46, on page 4-72.4.22.2 Measuring Methods and Measuring Ranges of the SM 331;AI 8 x 12 bitsMeasuring MethodsYou can set the following measuring methods for the input channels:• Voltage measurement• Current measurement• Resistance test• Temperature measurementYou perform the setting by means of the measuring range modules on the moduleand with the “measuring method” parameter in STEP 7.Unused ChannelsYou must short-circuit unused channels and connect them to M ANA . In this way,you obtain an optimum interference immunity for the analog input module. Set the“measuring method” parameter for unused channels to “disabled”. In this way youshorten the scan time of the module.If you do not use the COMP input, you must short-circuit it also.4-122Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesSpecial characteristics of unused channels for some measuring rangesSince configured inputs can remain unused because of the channel groupgeneration, you must take note of the following special characteristics of theseinputs to enable the diagnostic functions on the used channels.• Measuring range 1 to 5 V: Connect the unused input in parallel with a usedinput of the same channel group.• Current measurement, 2-wire transmitter:There are two ways to use the channels:a) Leave the unused input open and do not enable diagnostics for thischannel group. Otherwise, if diagnostics are enabled, the analog moduletriggers a single diagnostic interrupt and the SF LED of the analog modulecomes on.b) Connect the unused input with a resistance of 1.5 to 3.3 k. You may thenenable diagnostics for this channel group.• Current measurement 4 to 20 mA, 4-wire transmitter: Connect the unusedinput in series with an input of the same channel group.Special characteristic when all channels are disabledIf you disable all input channels of the module and enable diagnostics whenparameterizing the analog input module SM 331; AI 8 12 bits, the module doesnot indicate that the “external auxiliary voltage” is missing.Measuring rangesYou perform the setting of the measuring ranges by means of the measuring rangemodules on the module and with the “measuring method” parameter in STEP 7.Table 4-67 Measuring Ranges of the SM 331; AI 8 x 12 bitsMethod SelectedMeasuring Range(Type of Sensor)U: Voltage 80 mV 250 mV 500 mV 1000 mVTC-I:thermocouple(internal compensation)(thermovoltagemeasurement)TC-E: Thermocouple(external compensation)(thermovoltagemeasurement) 2.5 V 5 V1 to 5 V 10 VType N [NiCrSi-NiSi]Type E [NiCr-CuNi]Type J [Fe-CuNi]Type K [NiCr-Ni]Type L [Fe-CuNi]Measuring RangeModule SettingABADescriptionYou will find the digitizedanalog values in Section4.3.1 in the voltagemeasuring rangeYou will find the digitizedanalog values in Section4.3.1 in 80 mV the voltagemeasuring rangeProgrammable Logic Controllers S7-300 Module DataA5E00105505-034-123

Analog ModulesSpecial characteristics of the wire-break check for the 4 to 20 mA measuringrangeWith a parameterized measuring range of 4 to 20 mA and enabled wire-breakcheck, the analog input module enters wire-break in the diagnosis when a currentfalls below 3.6 mA.If you have enabled diagnostics interrupt during configuration, the moduleadditionally triggers a diagnostic interrupt.If no diagnostic interrupt has been enabled, the illuminated SF LED is the onlyindication of the wire-break and you must evaluate the diagnostic bytes in the userprogram.With a parameterized measuring range of 4 to 20 mA and disabled wire-breakcheck and enabled diagnostic interrupt, the module triggers a diagnostic interruptwhen the underflow is reached.4.23 Analog Input Module SM 331; AI 8 x RTD(6ES7331-7PF00-0AB0)Order number6ES7331-7PF00-0AB0CharacteristicsThe analog input module SM 331; AI 8 x RTD has the following characteristicfeatures:• 8 differential inputs for RTD resistance temperature detector in 4 channelgroups• Optional setting of the resistance thermometer type per channel group• Rapid measured value updating for up to 4 channels• Measured-value resolution 15 bits + sign (independent of integration time)• Programmable diagnostics• Programmable diagnostic interrupt• 8 channels with limit monitoring• Programmable hardware interrupt when limit has been exceeded• Programmable end-of-scan-cycle interrupt• Isolated against the backplane bus interfaceProgrammable Logic Controllers S7-300 Module DataA5E00105505-034-125

Analog ModulesChannel groupsThe channels of the SM 331; AI 8 x RTD are arranged in four groups of two. Youcan only ever assign parameters to one channel group.The table below shows which channels are parameterized as a channel group ineach case. You will need the channel group number to set the parameters in theuser program with an SFC.Table 4-69 Assignment of Channels of the SM 331; AI 8 x RTD to Channel GroupsChannels ...Channel 0Channel 1Channel 2Channel 3Channel 4Channel 5Channel 6Channel 7... form one Channel Group eachChannel group 0Channel group 1Channel group 2Channel group 3Special characteristic of channel groups for hardware interrupts upon limitviolationYou can set the upper and lower limits for each channel with hardware interrupts inSTEP 7.Module filtering modeThe SM 331; AI 8RTD operates in one of the following modes:• “Hardware filter, 8 channels”• “Software filter, 8 channels”• “Hardware filter, 4 channels”The operating mode affects the scan time of the module.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-131

Analog Modules”Hardware filter 8 channels” modeIn “Hardware filter 8 channels” mode, the analog input module SM331; AI 8 x RTDswitches over between the two channels in each group. As the module containsfour analog/digital converters (ADC), all four of the ADCs convert simultaneouslyfor channels 0, 2, 4 and 6. Once the even-numbered channels have beenconverted all the ADCs simultaneously convert for the odd-numbered channels 1,3, 5 and 7 (see Figure 4-42).Start analog conversion(simultaneous)K0 K2 K4 K6Scan timeStart analog conversion(simultaneous)K1 K3 K5 K7Figure 4-42Hardware filter 8 channels scan timeScan time of the moduleIn 8-channel hardware filter mode, the channel conversion time including thecommunication time of the analog input module SM 331; AI 8 x RTD is 85 ms. Themodule must then be switched over to the other channel in the group by means ofopto-MOS relays. Opto-MOS relays need 12 ms to switch and settle. Eachchannel needs a time of 97 ms, so that the scan time is exactly 194 ms.Scan time = (t K + t U ) x 2Scan time = (85 ms + 12 ms) x 2Scan time = 194 mst K :t U :channel conversion time for one channeltime for switching to the other channel in the channel group4-132Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules”Software filter 8 channels” modeIn “Software filter 8 channels” mode, the analog/digital conversion occurs in exactlythe same way as in “hardware filter 8 channels” mode. That is to say, as themodule contains four analog/digital converters (ADC), all four of the ADCs convertsimultaneously for channels 0, 2, 4 and 6. Once the even-numbered channels areconverted, all the ADCs convert simultaneously for the odd-numbered channels 1,3, 5 and 7 (see Figure 4-43).Start analog conversion(simultaneous)K0 K2 K4 K6Scan timeStart analog conversion(simultaneous)K1 K3 K5 K7Figure 4-43Software filter 8 channels scan timeScan time of the moduleThe channel conversion time depends, however, on the programmed interferencefrequency suppression. When you set an interference frequency of 50 Hz, thechannel conversion time including communication time is 30 ms. When you set aninterference frequency of 60 Hz, the channel conversion time is 25 ms. When youset an interference frequency of 400 Hz, the channel conversion time is reduced to8 ms. As with 8-channel hardware filter mode, the module must be switched overby means of opto MOS relays with a time of 12 ms for switching to the otherchannel of the group. This relationship is shown in the table that follows.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-133

Analog ModulesProlongation of the scan time with a wire-break checkThe wire-break check is a software function of the module that is available in alloperating modes.In the 8-channel hardware and software filter operating modes, the scan timeof the module is doubled, irrespective of the number of channels for whichwire-break has been enabled.In the 4-channel hardware filter operating mode, the module interruptsprocessing of the input data 170 ms and performs a wire-break check. In otherwords, each wire-break check prolongs the scan time of the module by 170 ms.Smoothing of the measured valuesYou fill find information that is generally applicable to the smoothing of analogvalues in Section 4.6.Special characteristic with short-circuit to M or LIf you short an input channel to M or L, the module does not suffer any damage.The channel continues to issue valid data; neither is a diagnosis reported.DiagnosticsYou will find the diagnostic messages that are grouped under the “group diagnosis”parameter in Table 4-46, on page 4-72.4.23.2 Measuring Methods and Measuring Ranges of theSM 331; AI 8 x RTDMeasuring MethodsYou can set the following measuring methods for the input channels:• RTD 4-conductor measurement• RTD 3-conductor measurement• Resistor 4-conductor measurement• Resistor 3-conductor measurementYou perform the setting with the “measuring method” parameter in STEP 7.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-135

Analog ModulesUnused ChannelsSet the “measuring method” parameter for unused channels to “disabled”. In thisway you shorten the scan time of the module.You must terminate an unused channel of an enabled channel group with anominal resistance in order to avoid diagnostic errors for the unused channel (referto the block diagram, Figure 4-41, for the connection).In the “4-Channel Hardware Filter” operating mode, termination is not necessaryprovided that you have disabled the unused channel groups. Channels 1, 3, 5 and7 are not monitored in this mode.Measuring rangesYou perform setting of the measuring ranges with the “measuring range” parameterin STEP 7.Table 4-71 Measuring ranges of the SM331; AI 8 x RTDMethod Selected Measuring Range DescriptionResistors:(Three-conductor/four-conductor terminal)Resistance RTD(Three-conductor/four-conductor terminal)150 300 600 Pt 100 climatePt 200 climatePt 500 climatePt 1000 climateNi 100 climateNi 120 climateNi 200 climateNi 500 climateNi 1000 climateCu 10 climatePt 100 standardPt 200 standardPt 500 standardPt 1000 standardNi 100 standardNi 120 standardNi 200 standardNi 500 standardNi 1000 standardCu 10 standardYou will find the digital analog values inSection 4.3.14-136Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesSpecial characteristic of parameter assignment to upper and lower limit valuesThe programmable limit values (triggers for hardware interrupt) differ for the AI 8RTD from the range of values shown in Table 4-68.The reason for this is that numerical methods in the module software for evaluatingthe process variables prevent values up to 32511 from being reported in somecases. The process input value at which a hardware interrupt for an underflow oroverflow occurs depends on the calibration factors for an individual channel andcan vary between the lower limits shown in the table below and 32511 (7EFF H ).Limit values should not be set at values higher than the minimum potential limitvalues shown in the table below.End-of-scan-cycle interruptBy enabling the end-of-scan-cycle interrupt, you can synchronize a process withthe conversion cycle of the module. The interrupt occurs when the conversion of allthe enabled channels is complete.Table 4-72 Content of the 4 bytes with additional information from OB40 during a hardwareinterrupt or an end-of-scan-cycle interruptContent of the 4 bytes withadditional information2 7 2 6 2 5 2 4 2 3 2 2 2 1 2 0 ByteSpecialanalogmarkers2 bits per channel to identify the rangeUpper limit exceeded inchannelLower limit exceeded inchannel7 6 5 4 3 2 1 0 07 6 5 4 3 2 1 0 1End-of-scan-cycle event X 2Unassigned bit 3Programmable Logic Controllers S7-300 Module DataA5E00105505-034-137

In otherwords, each wire-break check prolongs the scan time of the module by 93 ms.Smoothing of the measured valuesYou fill find information that is generally applicable to the smoothing of analogvalues in Section 4.6.Special characteristic with short-circuit to M or LIf you short an input channel to M or L, the module does not suffer any damage.The channel continues to issue valid data; neither is a diagnosis reported.DiagnosticsYou will find the diagnostic messages that are grouped under the “group diagnosis”parameter in Table 4-46, on page 4-72.Programmable Logic Controllers S7-300 Module DataA5E00105505-034-149

Analog Modules4.24.2 Measuring Methods and Measuring Ranges of the SM 331;AI 8 x TCMeasuring MethodsYou can set the following measuring methods for the input channels:• Thermocouple, linearization with reference temperature 0 °C• Thermocouple, linearization with reference temperature 50 °C• Thermocouples, linearization with internal comparison• Thermocouple, linearization with external comparisonYou perform the setting with the “measuring method” parameter in STEP 7.Unused ChannelsSet the “measuring method” parameter for unused channels to “disabled”. In thisway you shorten the scan time of the module.You must terminate an unused channel in an enabled channel group to avoiddiagnostic errors for the unused channel. To do this, short the Plus input and Minusinput of the channel.In the “4-Channel Hardware Filter” operating mode, termination is not necessaryprovided that you have disabled the unused channel groups. Channels 1, 3, 5 and7 are not monitored in this mode.Measuring rangesYou perform setting of the measuring ranges with the “measuring range” parameterin STEP 7.Table 4-76 Measuring Ranges of the SM331; AI 8 x TCMethod Selected Measuring Range DescriptionTC-L00C:(thermocouple, linear,reference temperature0 °C)TC-L50C:(thermocouple, linear,reference temperature50 °C)TC-IL:(thermocouple, linear,internal compensation)TC-EL:(thermocouple, linear,external compensation)Type BType CType EType JType KType LType NType RType SType TType UYou will find the digitized analog valuesin Section 4.3.1 in the temperature range4-150Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog ModulesSpecial characteristic of parameter assignment to upper and lower limit valuesThe programmable limit values (triggers for hardware interrupt) differ for theAI 8 x TC from the range of values shown in Table 4-73.The reason for this is that numerical methods in the module software for evaluatingthe process variables prevent values up to 32511 from being reported in somecases. The process input value at which a hardware interrupt for an underflow oroverflow occurs depends on the calibration factors for an individual channel andcan vary between the lower limits shown in the Table below and 32511 (7EFF H ).Limit values should not be set at values higher than the minimum potential limitvalues shown in the tables below.Table 4-77 Minimum Possible Upper and Lower Limit Values of SM 331; AI 8 x TC in °CThermocoupleMinimum PossibleUpper Limit ValueMinimum PossibleLower Limit Valuein °C Dec.

The “2nd” channel is used for current injection (I C ).The measured value is obtained by accessing the “1st” channel. The “2nd” channelhas the default carry value “7FFF H ”.Special characteristic of channel groups for hardware interruptsYou can set a hardware interrupt in STEP 7 for the channel group.

In this way,you obtain an optimum interference immunity for the analog input module. Set the“measuring method” parameter for unused channels to “disabled”. In this way youshorten the scan time of the module.If you do not use the COMP input, you must short-circuit it also.Special characteristics of unused channels for some measuring rangesSince configured inputs can remain unused because of the channel groupgeneration, you must take note of the following special characteristics of theseinputs to enable the diagnostic functions on the used channels.• Measuring range 1 to 5 V: Connect the unused input in parallel with a usedinput of the same channel group.• Current measurement, 2-wire transmitter:There are two ways to use the channels:a) Leave the unused input open and do not enable diagnostics for thischannel group. Otherwise, if diagnostics are enabled, the analog moduletriggers a single diagnostic interrupt and the SF LED of the analog modulecomes on.b) Connect the unused input with a resistance of 1.5 to 3.3 k You may thenenable diagnostics for this channel group.• Current measurement 4 to 20 mA, 4-wire transmitter: Connect the unusedinput in series with an input of the same channel group.Measuring rangesYou perform the setting of the measuring ranges by means of the measuring rangemodule on the module and with the “measuring method” parameter in STEP 7.4-160Programmable Logic Controllers S7-300 Module DataA5E00105505-03

The length of the cycle time can vary due toacyclic program branching.• Free running, variable DP cycle at the PROFIBUS subnetwork• Free running cycle at the DP-Slave back plane bus.• Free running cycle during the signal conditioning and conversion in theelectronic modules of the DP-Slave.In the case of equidistance the DP cycle runs in phase and with the same length.In this cycle the processing levels of a CPU (OB 61 to OB 64) and thesynchronous peripheral are synchronized. The I/O data are therefore transferred atdefined and consistent time intervals (clock synchronicity).Requirements• The DP-Master and DP-Slave must support the synchronicity. They requireSTEP 7 from Version 5.2.4-172Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Analog Modules4.30.1 Commissioning the SM 334; AI 4/AO 2 x 8/8 bitsThe analog/output module SM 334; AI 4/AO 2 x 8/8 bits is a non-isolated module.You cannot program the SM 334; AI 4/AO 2 x 8/8 bits.Important information on connecting the moduleNoteNote when connecting the SM 334 that:• the analog chassis ground M ANA (terminal 15 or 18) is connected to thechassis ground M of the CPU and/or the interface module (IM). Use a wirewith a minimum cross-section of 1 mm 2 for this.If there is no ground connection between M ANA and M, the module switchesoff. Inputs are read with 7FFF H ; outputs return a value of 0. If the module is runwithout a ground connection for some time, it may be destroyed.• the supply voltage for the CPU and/or the interface module (IM) must notbe connected with reversed polarity. Reverse polarity causes thedestruction of the module because M ANA is subjected to an unauthorized highpotential (+24 V).AddressingThe inputs and outputs of the module are addressed as of the initial moduleaddress.The address of a channel is obtained from the module start address and anaddress offset.Input AddressesThe following addresses apply to the inputs:ChannelAddress0 Initial module address1 Module start address + 2 bytes address offset2 Module start address + 4 bytes address offset3 Module start address + 6 bytes address offset4-192Programmable Logic Controllers S7-300 Module DataA5E00105505-03

In this way, you obtain an optimum noise immunity for the analog module.Unused output channels must be left open.Measuring rangesThe SM 334; AI 4/AO 2 x 8/8 bits has the measuring ranges 0 to 10 V and 0 to 20mA.Unlike the other analog modules, the SM 334 has a lower resolution and nonegative measuring ranges. Take this into account when you read measured valuetables 4-10 and 4-14 on pages 4-13 and 4-15.Output rangesThe SM 334; AI 4/AO 2 x 8/8 bits has the output ranges 0 to 10 V and 0 to 20 mA.Unlike the other analog modules, the SM 334 has a lower resolution the analogoutputs do not have underranges.

Analog ModulesNoteSimultaneous connection of a temperature sensor and a resistor to channels 0 and1 and 2 and 3 is not allowed.The reason common current source for both channels.Unused ChannelsSet the “measuring method” parameter for unused input channels to “disabled”. Inthis way you shorten the scan time of the module.You must short-circuit unused input channels and you should connect them toM ANA . In this way, you obtain an optimum interference immunity for the analoginput module.So that unused output channels of the SM 334; AI 4/AO 2 x 12 bits remainde-energized, you must set the “output type” parameter to “disabled” and leave theterminal open.Measuring rangesUse STEP 7 for programming the measuring ranges.Table 4-87 Measuring ranges of the SM 334;AI 4/AO 2 x 12 bitsMethod Selected Measuring Range DescriptionU: Voltage 0 to 10 V You will find the digitalanalog values in SectionR-4L: Resistance (four-conductor 10 k4.3.1connection)RTD-4L: Bulb resistorPt 100 climate(linear, four-conductor connection)(temperature measurement)Default settings of inputsThe default settings of the module are the “Bulb resistor (linear, four-conductorconnection)” measuring method and the “Pt 100 climate” measuring range.

Special Signal modules5.3 Dummy Module DM 370; (6ES7370-0AA01-0AA0)Order number6ES7370-0AA01-0AA0CharacteristicsThe dummy module DM 370 reserves a slot for a non-parameterized module. Theycan be used as placeholders for:• Interface modules (without reservation of address space)• Non-parameterized signal modules (with reservation of address space)• Modules which occupy 2 slots (with reservation of address space)When replacing the dummy module with another module from S7-300, themechanical assembly and the address assignment/address allocation of the entireassembly remain unchanged.Configuration with STEP 7You must only configure the dummy module DM 370 with STEP 7 if the module ofthe slot is to be reserved for a parameterized signal module. If the module isreserving the slot for an interface module, the configuration cannot be carried outwith STEP 7.Modules which occupy 2 slotsFor modules which occupy 2 slots, you must plug in 2 dummy modules. Only thedummy module in slot “x” reserves the address space (not the dummy module inslot “x + 1”; for details of the procedure, see table 5-2).A maximum of 8 modules may be plugged into a module carrier (SM/FM/CP). Ifyou, for example, reserve a slot for an 80 mm wide module with 2 dummymodules, you may still plug in 7 other modules (SM/FM/CP) because the dummymodule only occupies the address space for 1 module.Programmable Logic Controllers S7-300 Module DataA5E00105505-035-5

Special Signal modules5.4.1 Synchronous OperationNoteThe basics of synchronous operation are described in a separate manual.Hardware requirementsFor the synchronous operation of the SM 338, you require:• CPU which supports clocked operation• DP master which supports the equidistant bus cycle• Slave interface (IM 153-x) which supports synchronous operationCharacteristicsDepending on the system parameterization, the SM 338 works in eithernon-synchronous or synchronous mode.In synchronous operation, the data exchange between DP master and SM 338 issynchronous to the PROFIBUS DP cycle.In synchronous operation all 16 bytes of the checkback interface are consistent.If synchronicity is lost due to faults or failure or delay of Global Control (GC), theSM 338 goes back into synchronous operation in the next cycle without errorresponse.If synchronicity is lost, the checkback interface is not updated.5-8Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Thus, connect pin 2 of the SM 338 (M) with low impedance with theground of the CPU.• The encoder lines (pins 3 to 14) must be twisted pairs and shielded. Apply theshield to both sides.For the shield connection to the SM 338, use the shield connection element(order number 6ES7390-5AA00-0AA0).• If the output current (900 mA) of the encoder supply is exceeded, then youmust connect an external power supply.Programmable Logic Controllers S7-300 Module DataA5E00105505-035-9

Special Signal modules5.4.3 Functions of the SM 338; POS INPUT5.4.4 Encoder value acquisitionThe absolute value encoder transfers its encoder values in messages to theSM 338. The transfer of the message is initiated by the SM 338.• In non-synchronous operation, the encoder values are acquired while it is freerunning.• In synchronous operation the encoder values are acquired synchronized to thePROFIBUS DP cycle at each T i .Free running encoder value acquisitionThe SM 338 always initiates the transfer of a message after the end of theparameterized monoflop time.Asynchronous to these free running messages, the SM 338 processes theacquired encoder values during the cycle of its updating rate (see Technical Data).Thus, in the case of free running encoder value acquisition, encoder values ofdifferent ages result. The difference between the maximum and minimum age isthe jitter (see Technical Data).Synchronous encoder values acquisitionSynchronous encoder values acquisition is automatically set if, in the DP mastersystem, the equidistant bus cycle is activated and the DP Slave is synchronized tothe DP cycle.The SM 338 initiates the transfer of a message in each PROFIBUS DP cycleat the time T i .Synchronous to the PROFIBUS DP cycle, the SM 338 processes the transferredencoder values.5-10Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Special Signal modules5.4.5 Gray/Dual ConverterIn the Gray setting, the encoder values provided by the absolute value encoder ingray code is converted into Dual code. In the Dual setting, encoder valuesprovided by the absolute value encoder remain unchanged.NoteIf you have selected the Gray setting, the SM 338 always converts the entireencoder value (13, 21, 25 bits). As a result, preceding special bits affect theencoder values and following bits could be falsified under certain circumstances.5.4.6 Transferred Encoder Value and NormalizationThe transferred encoder value contains the encoder position of the absolute valueencoder. Depending on the encoder used, additional bits which are located beforeand after the encoder position are also transferred in addition to the encoderposition.So that the SM 338 can detect the encoder position, make the following settings:• Normalization, places (0..12), or• Normalization, units / revolutionNormalization, placesThe normalization determines the position of the encoder values in the checkbackinterface.• If “Places” = 1, 2....12, this indicates that the following non relevant bits in theencoder values are removed and the encoder value is right justified in theaddress range (see following example).• If “Places” = 0, this indicates that the following bits are retained and availablefor evaluation.This can be useful if you use an absolute value encoder which transfersinformation in the following bits (see manufacturer information) and you want toevaluate these (see also chapter 5.4.5).Parameter units / revolutionA maximum of 13 bits are available for the units/revolution.

Thefreeze function is coupled to the digital inputs DI 0 and DI 1 of the SM 338.The freeze is triggered by an edge change (rising edge) on DI 0 or DI 1. A frozenencoder value is identified by the bit 31 (output address) being set. With a digitalinput you can freeze one, two or three encoder values.You must switch on the freeze function, i.e. set the corresponding parameters inSTEP 7 .The encoder values are retained until the freeze function is ended and can thus beevaluated dependent on the event.5-12Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Special Signal modulesEnding the freeze functionThe freeze function must be ended at every encoder input. You acknowledge thefunction in the user program by setting the bit 0, 1 or 2 depending on the channelwith the STEP 7-Operation T PAB “xyz” (for a program example, see chapter5.4.9).After exiting, bit 31 of the corresponding encoder value is again deleted and theencoder values are again updated. A renewed freezing of the encoder values isagain possible as soon as you have deleted the acknowledgment bit in the outputaddress of the module.In synchronous operation the acknowledgment is processed at time T o . From thispoint in time a renewed freezing of the encoder values can take place via thedigital inputs.NoteThe freeze function is automatically acknowledged if you newly parameterize thecorresponding channel with different parameters (see 5.4.8 chapter).If the parameters remain identical, the freeze function remains unaffected.5.4.8 SM 338; POS-INPUT ParameterizationYou parameterize the SM 338; POS-INPUT with STEP 7. You must performparameter assignment in STOP mode of the CPU.As soon as you have set all the parameters, download the parameters from theprogramming device to the CPU. On a transition from STOP to RUN mode, theCPU then transfers the parameters to the SM 338.The parameters cannot be changed by the user program.Programmable Logic Controllers S7-300 Module DataA5E00105505-035-13

The parameterized monofloptime must be greater than the monoflop time of the absolute value encoder (see technical data of themanufacturer). The time 2 (1 / baud rate) is added to the value parameterized in HW config. At abaud rate of 125 kHz with a parameterized monoflop time of 16 s, an effective monoflop time of 32 sis actually achieved.3) The following restriction applies to the monoflop time of the absolute value encoder:(1 / baud rate) < Monoflop time of the absolute value encoder < 64 s + 2 (1 / baud rate)4) to the power of twoNotePlease note that in non synchronous operation the baud rate and the monofloptime affect the accuracy and actuality of the encoder values.In synchronous operation the baud rate and the monoflop time affect the accuracyof the freeze function.5-14Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Special Signal modules5.4.10 Diagnosis of the SM 338; POS-INPUTThe SM 338 makes diagnostic messages available, i.e., all diagnostic messagesare always provided by the SM 338 without your assistance.Actions following diagnostic message in STEP 7Each diagnostic message leads to the following actions:• The diagnostic message is entered in the diagnosis of the module andforwarded to the CPU.• The SF LED on the module lights.• If you have programmed “Enable Diagnostic Interrupt” in STEP 7 , a diagnosticinterrupt is triggered and OB 82 is called.Reading out diagnostic messagesYou can read out detailed diagnostic messages by means of SFCs in the userprogram (refer to the Appendix “Diagnostic Data of Signal Modules”).You can view the cause of the error in STEP 7, in the module diagnosis (refer toonline Help for STEP 7).Diagnostic message via SF LEDThe SM 338 indicate errors for you by means of their SF LED (group error LED).The SF LED lights as soon as a diagnostic message is triggered by the SM 338. Itgoes out when all errors have been rectified.The group fault (SF) LED also lights up in case of external errors (short circuit ofencoder supply), independent of the operating status of the CPU (if power is on).The SF LED lights up temporarily at startup during the self test of the SM 338.Programmable Logic Controllers S7-300 Module DataA5E00105505-035-17

Special Signal modules5.4.11 Interrupts of the SM 338; POS INPUTIntroductionIn this Section, the interrupt behavior of the SM 338; POS-INPUT is described.The SM 338 can trigger diagnostic interrupts.The OBs and SFCs mentioned below can be found in the online Help for STEP 7,where they are described in greater detail.Enabling interruptsThe interrupts are not preset – in other words, they are inhibited withoutappropriate parameter assignment. Assign parameters to the Interrupt Enable inSTEP 7 (refer to Section 5.4.8).Diagnostic interruptIf you have enabled diagnostic interrupts, then incoming active error events (initialoccurrence of the error) and departing error events (message aftertroubleshooting) are reported by means of interrupts.The CPU interrupts execution of the user program and processes the diagnosticinterrupt block (OB 82).In the user program, you can call SFC 51 or SFC 59 in OB 82 to obtain moredetailed diagnostic information from the module.The diagnostic information is consistent until such time as OB 82 is exited. WhenOB 82 is exited, the diagnostic interrupt is acknowledged on the module.5-20Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Guidelines for Handling ElectrostaticSensitive Devices (ESD)EIntroductionIn this appendix, we explain• what is meant by “electrostatic sensitive devices”• the precautions you must observe when handling and working with electrostaticsensitive devices.ContentsThis chapter contains the following sections on electrostatic sensitive devices:Section Contents PageE.1 What is ESD? E-2E.2 Electrostatic Charging of Persons E-3E.3 General Protective Measures Against Electrostatic DischargeDamageE-4Programmable Logic Controllers S7-300 Module DataA5E00105505-03E-1

E.1 What is ESD?DefinitionAll electronic modules are equipped with large-scale integrated ICs or components.Due to their design, these electronic elements are very sensitive to overvoltagesand thus to any electrostatic discharge.The abbreviation ESD has been introduced for these Electrostatic SensitiveDevices/Modules. The designation ESD is used internationally for electrostaticsensitive device.Electrostatic sensitive devices are labeled with the following symbol:!CautionElectrostatic sensitive devices are subject to voltages that are far below thevoltage values that can still be perceived by human beings. These voltages arepresent if you touch a component or the electrical connections of a module withoutpreviously being electrostatically discharged. In most cases, the damage causedby an overvoltage is not immediately noticeable and results in total damage onlyafter a prolonged period of operation.E-2Programmable Logic Controllers S7-300 Module DataA5E00105505-03

Guidelines for Handling Electrostatic Sensitive Devices (ESD)E.2 Electrostatic Charging of PersonsChargingEvery person with a non-conductive connection to the electrical potential of itssurroundings can be charged electrostatically.Figure E-1 shows you the maximum values for electrostatic voltages which canbuild up on a person coming into contact with the materials indicated in the figure.These values are in conformity with the specifications of IEC 801-2.Voltage in kV(kV)16151413121110987654321351020 30 40 50 60 70 80 90 100121 Synthetic material2 Wool3 Antistatic material,for example, woodor concreteRelative airhumidity in %Figure E-1Electrostatic Voltages which Can Build up on a PersonProgrammable Logic Controllers S7-300 Module DataA5E00105505-03E-3

E.3 General Protective Measures Against Electrostatic DischargeDamageEnsure sufficient groundingMake sure that the personnel, working surfaces and packaging are sufficientlygrounded when handling electrostatic sensitive devices. You thus avoidelectrostatic charging.Avoid direct contactYou should touch electrostatic sensitive devices only if it is unavoidable(for example, during maintenance work). Hold modules without touching the pins ofcomponents or printed conductors. In this way, the discharged energy cannotaffect the sensitive devices.If you have to carry out measurements on a module, you must discharge yourbody before you start the measurement by touching grounded metallic parts. Usegrounded measuring devices only.E-4Programmable Logic Controllers S7-300 Module DataA5E00105505-03

GlossaryAddressAn address denotes a specific operand or address area; examples of this are:input I 12.1; memory word MW 25; data block DB 3.Aggregate current→Sum of the currents of all output channels on a digital output module.Backplane bus →→ The backplane bus is a serial data bus that is used by the modules to communicatewith each other and to supply them with the voltage they require. Theinterconnection of the modules is established by the bus connector.Basic conversion timeTime for the actual encoding of a channel (integration time) plus the requiredtimes for the internal control; i. e. after this time a channel is completely processed.Basic error limitThe basic error limit is the operational limit at 25 °C, referred to the rated rangeof the analog module.Basic response timeTime which an analog input/output module requires for a cycle if all channels arereleased; it corresponds to the “number of all channels x basic conversion time”.BusA bus is a transmission medium that interconnects several nodes. Data transmissioncan be serial or parallel, and be performed over electric conductors or fiberopticcables.Bus segmentA bus segment is a self-contained section of a serial bus system. Bus segmentsare interconnected by means of →repeaters.Programmable Logic Controllers S7-300 Module DataA5E00105505-03Glossary-1

The compensating box is a compensation circuitfor compensating temperature fluctuations at the → Comparison point.Complete restartWhen a CPU starts up (say, when the mode selector switch is moved fromSTOP to RUN or when the mains supply is turned on), OB 100 (Restart) is processedbefore cyclic programming processing (OB 1).With a complete restart, the → Process input image is read in and the STEP 7user program is processed, starting with the first instruction in OB1.ConfigureSelect and put together different components on a programmable logic controllerand install the requisite software and adapt to the specific use (for example, byassigning parameters to the modules).CP→Communications processorCPUThe CPU (central processing unit) is a CPU module of the →programmablelogic controller that stores and runs the user program. It contains the operatingsystem, memory, processing unit and communication interface.Glossary-2Programmable Logic Controllers S7-300 Module DataA5E00105505-03

GlossaryDefault settingThe default setting is a sensible basic setting that is used whenever no othervalue is used.Destruction limitLimit of permitted input voltage / input current.If this limit is exceeded, the measuring accuracy may deteriorate. If the destructionlimit is exceeded by a vast amount, this may destroy the internal measuringcircuit.Diagnostic bufferThe diagnostic buffer is a buffered memory area in the CPU which stores thediagnostics events in the order in which they occurred.For troubleshooting, the user can read out the exact error cause in STEP 7(PLC –> Module State) from the diagnostic buffer.Diagnostic dataAll the diagnostics events that occurred are collected in the CPU and entered inthe → Diagnostic buffer. If there is an error OB, it is started.Diagnostic InterruptModules with diagnostics capability report system errors by means of diagnosticinterrupts to the → CPU. The operating system of the CPU calls OB 82 in thecourse of a diagnostic interrupt.DiagnosticsGeneric term for → System diagnostics, process error diagnosis and user-defineddiagnostics.Direct accessA direct access is the direct accessing of the CPU by means of the → Backplanebus to modules while avoiding the → Process image.Encoder absoluteAn encoder absolute determines the path traveled during position detection byreading a numerical value. In the case of encoders absolute with a serial interface(SSI), path information is transferred synchronously and serially accordingto the SSI protocol (synchronous serial interface).Programmable Logic Controllers S7-300 Module DataA5E00105505-03Glossary-3

TheFREEZE function is a control command for freezing current encoder values ofthe SM 338 to the instantaneous value.GroundThe conductive ground whose electric potential can be set equal to zero at everypoint.In the proximity of grounding electrodes, the ground can have a potential differingfrom zero. The term “reference ground” is frequently used to describe such circumstances.Ground, toTo ground means connect an electrically conductive part by means of a groundingsystem to the grounding electrode (one or more conductive parts having avery good contact to ground).Hardware interruptA hardware interrupt is triggered by interrupt-triggering modules as a result of acertain event in the process (overshooting or undershooting of a limit value; amodule has completed the cyclic conversion of its channels).The hardware interrupt is reported to the CPU. In accordance with the priority ofthis interrupt, the →Organization block assigned to it is scanned.Hold last value (LWH)The module retains the last value read out before STOP mode.Input delayParameter in STEP 7 for digital input modules. The input delay is used to suppressinjected interference. Interfering pulses from 0 ms to the set input delayare suppressed.The set input delay is subject to a tolerance, which can be taken from the technicalspecifications of the module. A high input delay suppresses long interferingpulses, whereas a low input delay suppresses short ones.The permissible input delay depends on the length of the cable between the encoderand the module. For example, a high input delay has to be set for long unshieldedsupply conductors to the encoder (longer than 100m).Glossary-4Programmable Logic Controllers S7-300 Module DataA5E00105505-03

This parameter is used by the user tospecify the prevailing line frequency on his system.InterruptThe SIMATIC S7 is familiar with 28 different run-time level, which govern runningof the user program. These run-time levels include interrupts such as hardwareinterrupts, among other things. When an interrupt occurs, the operating systemautomatically calls an assigned organization block in which the user can programthe reaction he wants (for example, in an FB).Interrupt, diagnostic→ Diagnostic InterruptInterrupt, end-of-scan-cycle interrupt→ Hardware interruptInterrupt, hardware→ Hardware interruptLinearity errorThe linearity error identifies the maximum deviation of the measured/output valuefrom the ideal linear relationship between the measuring/output signal and thedigital value. The data is a percentage and relates to the rated range of the analogmodule.Logic blockIn a SIMATIC S7 context, a logic block is a block that contains a part of theSTEP 7 user program. By contrast, a data block only contains data. There arethe following logic blocks: organization blocks (OBs), function blocks (FBs), functions(FCs), system function block (SFBs), system functions (SFCs).Programmable Logic Controllers S7-300 Module DataA5E00105505-03Glossary-5

STARTUP can be triggered by the → Mode switch or following power-onor by means of an operator input on the programming device. With theS7-300 and M7-300, a → Complete restart is performed.Status modeThe SIMATIC S7 programmable logic controllers are familiar with the following ofstatus modes: STOP, → STARTUP, RUN and STOP.Substitute valueSubstitute values are values that can be output to the process when signal outputmodules have failed or be used in the user program instead of a processvalue when signal input modules have failed.The substitute values can be assigned parameters by the user in STEP 7 (oldvalue retained, substitute value 0 or 1). They are values which the output(s) haveto output in the event of a CPU STOP.System diagnosticsSystem diagnostics is the detection, analysis and reporting of errors that occurwithin the programmable logic controller.

Reparameterization steps in RUN modeObserve the reparameterization steps described in the above manual.Note the peculiarities of certain modules described in the table.Example 1:To change a measuring range for modules, proceed as follows:1. Change the user program so that the channel to be reparameterized is nolonger evaluated, and download it to the CPU.2. Change the measuring range for the module in HWCONFIG, and download thechanged configuration to the CPU.3. Adapt the user program to the changed channel, and download it to the CPU.Example 2:When reparameterizing certain modules (see the table), you should ensure thatthere is no pending diagnostic event (e.g. a wire break message) before carryingout reparameterization, since otherwise it may happen in some cases that outgoingdiagnostic events are no longer reported. As a result, the SF LEDs on the CPU,IM, or module will continue to shine, for example, although the reparameterizedmodule is working correctly. If such a situation does arise, however, the modulemust be removed and then plugged in again.2Product Information on the ManualA5E00201782-03

Cycle length can vary, due toacyclical program branches.Asynchronous, variable DP cycle on the PROFIBUS subnetAsynchronous cycle on the DP slave backplane busAsynchronous cycle during signal conditioning and conversion in the electronicmodules of the DP slavesWith equidistance, the DP cycle operates in the same clock cycle, with the samelength. The execution levels of a CPU (OB61 to OB64) and the synchronous I/Oare synchronized with this clock cycle. Thus, I/O data are transferred in defined,constant time intervals (synchronous operation). The maximum “jitter” is 50 µs.RequirementsThe DP master and DP slave must support synchronous operation.

Channel groupsThe channels of the SM 331; AI 8 x RTD are arranged in four groups of two. Youcan only ever assign parameters to one channel group.The table below shows which channels are parameterized as a channel group ineach case. You will need the channel group number to set the parameters in theuser program with an SFC.Table 2Assignment of Channels of the SM 331; AI 8 x RTD to Channel GroupsChannels ...Channel 0Channel 1Channel 2Channel 3Channel 4Channel 5Channel 6Channel 7... form one Channel Group eachChannel group 0Channel group 1Channel group 2Channel group 3Special characteristic of channel groups for hardware interrupts upon limitviolationYou can set the upper and lower limits for each channel with hardware interrupts inSTEP 7.Module filtering modeThe SM 331; AI 8RTD operates in one of the following modes: “Hardware filter, 8 channels” “Software filter, 8 channels” “Hardware filter, 4 channels”The operating mode affects the scan time of the module.Product Information S7-300 Analog Input Module SM 331; AI 8 x RTDA5E00400156-019

”Hardware filter 8 channels” modeIn “Hardware filter 8 channels” mode, the analog input module SM331; AI 8 x RTDswitches over between the two channels in each group. As the module containsfour analog/digital converters (ADC), all four of the ADCs convert simultaneouslyfor channels 0, 2, 4 and 6. Once the even-numbered channels have beenconverted all the ADCs simultaneously convert for the odd-numbered channels 1,3, 5 and 7 (see Figure 2).Start analog conversion(simultaneous)K0 K2 K4 K6Scan timeStart analog conversion(simultaneous)K1 K3 K5 K7Figure 2Hardware filter 8 channels scan timeScan time of the moduleIn 8-channel hardware filter mode, the channel conversion time including thecommunication time of the analog input module SM 331; AI 8 x RTD is 84 ms. Themodule must then be switched over to the other channel in the group by means ofopto-MOS relays. Opto-MOS relays need 16 ms to switch and settle. Eachchannel needs a time of 100 ms, so that the scan time is exactly 200 ms.Scan time = (t K + t U ) x 2Scan time = (84 ms + 16 ms) x 2Scan time = 200 mst K :t U :channel conversion time for one channeltime for switching to the other channel in the channel group10Product Information S7-300 Analog Input Module SM 331; AI 8 x RTDA5E00400156-01

”Software filter 8 channels” modeIn “Software filter 8 channels” mode, the analog/digital conversion occurs in exactlythe same way as in “hardware filter 8 channels” mode. That is to say, as themodule contains four analog/digital converters (ADC), all four of the ADCs convertsimultaneously for channels 0, 2, 4 and 6. Once the even-numbered channels areconverted, all the ADCs convert simultaneously for the odd-numbered channels 1,3, 5 and 7 (see Figure 3).Start analog conversion(simultaneous)K0 K2 K4 K6Scan timeStart analog conversion(simultaneous)K1 K3 K5 K7Figure 3Software filter 8 channels scan timeScan time of the moduleThe channel conversion time depends, however, on the programmed interferencefrequency suppression. When you set an interference frequency of 50 Hz, thechannel conversion time including communication time is 32 ms. When you set aninterference frequency of 60 Hz, the channel conversion time is 27 ms. When youset an interference frequency of 400 Hz, the channel conversion time is reduced to9 ms. As with 8-channel hardware filter mode, the module must be switched overby means of opto MOS relays with a time of 16 ms for switching to the otherchannel of the group. This relationship is shown in the table that follows.Product Information S7-300 Analog Input Module SM 331; AI 8 x RTDA5E00400156-0111

Asthe module does not switch over between the channels in a group, the channelscan time and the module scan time are the same: 10 ms.Channel conversion time = channel scan time = module scan time = 10 ms12Product Information S7-300 Analog Input Module SM 331; AI 8 x RTDA5E00400156-01

Prolongation of the scan time with a wire-break checkThe wire-break check is a hardware function of the module that is available in alloperating modes.In the 8-channel hardware and software filter operating modes, the scan timeof the module is unchanged, irrespective of the number of channels for whichwire-break has been enabled.In the 4-channel hardware filter operating mode, the module interruptsprocessing of the input data 100 ms and performs a wire-break check. In otherwords, each wire-break check prolongs the scan time of the module by 100 ms.Smoothing of the measured valuesYou fill find information that is generally applicable to the smoothing of analogvalues in Section 4.6 of the SIMATIC Programmable Logic Controller S7-300Module Data Reference Manual .Special characteristic with short-circuit to M or LIf you short an input channel to M or L, the module does not suffer any damage.The channel continues to issue valid data; neither is a diagnosis reported.DiagnosticsYou will find the diagnostic messages that are grouped under the “group diagnosis”parameter in Section 4.16 of the SIMATIC Programmable Logic Controller S7-300Module Data Reference Manual .Product Information S7-300 Analog Input Module SM 331; AI 8 x RTDA5E00400156-0113

Measuring Methods and Measuring Ranges of the SM 331; AI 8 x RTDMeasuring MethodsYou can set the following measuring methods for the input channels: RTD 4-conductor measurement RTD 3-conductor measurement Resistor 4-conductor measurement Resistor 3-conductor measurementYou perform the setting with the “measuring method” parameter in STEP 7.Unused ChannelsSet the “measuring method” parameter for unused channels to “disabled”. In thisway you shorten the scan time of the module.You must terminate an unused channel of an enabled channel group with anominal resistance in order to avoid diagnostic errors for the unused channel (referto the block diagram, Figure 1, for the connection).In the “4-Channel Hardware Filter” operating mode, termination is not necessaryprovided that you have disabled the unused channel groups. Channels 1, 3, 5 and7 are not monitored in this mode.Measuring rangesYou perform setting of the measuring ranges with the “measuring range” parameterin STEP 7.Table 4Measuring ranges of the SM331; AI 8 x RTDMethod SelectedDeactivatedResistance, four-conductorconnectionResistance, three-conductorconnectionDeactivated150 300 600 150 300 600 Measuring Range14Product Information S7-300 Analog Input Module SM 331; AI 8 x RTDA5E00400156-01

Scan time of the moduleIn the 8-channel software filter mode of analog input module SM331; AI 8 x TC, thechannel conversion time is guided by the interference frequency set. When you setan interference frequency of 50 Hz, the channel conversion time includingcommunication time is 76 ms. When you set an interference frequency of 60 Hz,the channel conversion time is 65 ms. When you set an interference frequency of400 Hz, the channel conversion time is reduced to 16 ms. As with 8-channelhardware filter mode, the module must be switched over by means of opto MOSrelays with a switchover time of 7 ms to the other channel of the group. Table 3shows the scan time of the module at a certain interference frequency.Table 3Scan Times in “Software Filter, 8 Channels” ModeProgrammedInterference FrequencySuppressionChannel Scan Time*Module Scan Time (AllChannels)50 Hz 83 ms 166 ms60 Hz 72 ms 144 ms400 Hz 23 ms 46 ms* Channel scan time = channel conversion time + 7 ms switching time to the other channelin the channel group“Hardware filter 4 channels” modeIn 4-channel hardware filter mode, the analog input module SM331; AI 8 x TC doesnot switch over between the channels of the individual groups.

Scan time of the moduleIn 4-channel hardware filter mode, the channel conversion time including thecommunication time of analog input module SM331; AI 8 x TC is 10 ms. As themodule does not switch over between the channels in a group, the channel scantime and the module scan time are the same: 10 ms.Channel conversion time = channel scan time = module scan time = 10 msProlongation of the scan time with a wire-break checkThe wire-break check is a software function of the module that is available in alloperating modes.In the 8-Channel Hardware and Software Filter operating mode prolongs thescan time of the module by 4 ms, irrespective of the number of channels for whichwire-break has been enabled.In the 4-Channel Hardware Filter operating mode, the module interruptsprocessing of the input data 170 ms and performs a wire-break check. In otherwords, each wire-break check prolongs the scan time of the module by 93 ms.Smoothing of the measured valuesYou fill find information that is generally applicable to the smoothing of analogvalues in Section 4.6 of the SIMATIC Programmable Logic Controllers S7 -300Module Data Manual.Special characteristic with short-circuit to M or LIf you short an input channel to M or L, the module does not suffer any damage.The channel continues to issue valid data; neither is a diagnosis reported.DiagnosticsYou will find the diagnostic messages that are grouped under the “group diagnosis”parameter in Table 4--46, on page 4--72 of the SIMATIC Programmable LogicControllers S7 -300 Module Data Manual.Product Information S7 -300 Analog Input Module SM 331; AI 8 x TCA5E00455107-0113

Connecting ThermocouplesDesign of thermocouplesA thermocouple consists of a pair of sensors and the necessary installation andconnecting parts. The thermocouple consists of two wires of dissimilar metals ormetal alloys soldered or welded together at the ends.There are different types of thermocouple, depending on the composition of thematerial used -- for example, K, J, N thermocouples. The measuring principle of allthermocouples is the same, irrespective of their type.Measuring junctionThermocouple with positive or negative limbsConnecting pointCompensating leadsReference junctionLeads° CPoint at which thermo-e. m. f. is measuredFigure 6Design of ThermocouplesPrinciple of Operation of ThermocouplesIf the measuring point is subjected to a temperature different from that of the freeends of the thermocouple (point of connection), a voltage, the thermo emf, occursat the free ends. The magnitude of the thermo-e.m.f. generated depends on thedifference between the temperature at the measuring junction and the temperatureat the free ends, as well as on the material combination used for the thermocouple.Since a thermocouple always measures a temperature difference, the free endsmust be kept at a known temperature at a reference junction in order to determinethe temperature of the measuring junction.The thermocouples can be extended from their point of connection to the referencejunction by means of compensating wires. These compensating wires consist ofthe same material as the thermocouple wires. The supply leads are copper wire.Note: Make sure these wires are connected with the correct polarity, otherwisethere will be considerable measuring errors.14Product Information S7 -300 Analog Input Module SM 331; AI 8 x TCA5E00455107-01

Compensation of the reference junction temperatureYou can compensate for the effects of temperature fluctuations at the referencejunction by means of compensating leads.There are several options for you to choose from for acquiring the referencejunction temperature in order to obtain an absolute temperature value from thedifference in temperature between the reference junction and measuring point.You can use internal or external compensation, depending on where you want thereference junction to be.Table 4Options for Compensation of the Reference Junction TemperatureNo compensationOptionInternal compensation(refer to Figure 7 for connection)External compensation with resistancethermometer for acquisition of the referencejunction temperature(refer to Figure 8 and LEERER MERKERforconnection)ExplanationIf you want to acquire only the difference in temperaturebetween the measuring point and the reference junction.If you employ internal compensation, the internaltemperature (thermocouple internal comparison) of themodule is used for comparison purposes.You can acquire the reference temperature by means of aresistance thermometer and have it calculated by themodule for any thermocouple.Theory of operation of internal compensationWith internal compensation, you can establish the reference point across theterminals of the analog input modules. In this case, you must run thecompensating lines right up to the analog module. The internal temperature sensoracquires the temperature of the module and supplies a compensation voltage.Note that internal compensation is not as accurate as external compensation.Product Information S7 -300 Analog Input Module SM 331; AI 8 x TCA5E00455107-0115

Measuring Methods and Measuring Ranges of the Analog Input ModuleSM 331; AI 8×TCMeasuring MethodsYou can set the following measuring methods for the input channels:S Thermocouple, linearization with reference temperature 0 °CS Thermocouple, linearization with reference temperature 50 °CS Thermocouples, linearization with internal comparisonS Thermocouple, linearization with external comparisonYou perform the setting with the “measuring method” parameter in STEP 7.Unused ChannelsSet the “measuring method” parameter for unused channels to “disabled”. In thisway you shorten the scan time of the module.You must terminate an unused channel in an enabled channel group to avoiddiagnostic errors for the unused channel. To do this, short the Plus input and Minusinput of the channel.In the “4-Channel Hardware Filter” operating mode, termination is not necessaryprovided that you have disabled the unused channel groups. Channels 1, 3, 5 and7 are not monitored in this mode.Measuring rangesYou perform setting of the measuring ranges with the “measuring range” parameterin STEP 7.Table 5Measuring Ranges of the SM331; AI 8 x TCMethod Selected Measuring Range DescriptionTC-L00C:(thermocouple, linear,reference temperature0 °C)TC-L50C:(thermocouple, linear,reference temperature50 °C)TC-IL:(thermocouple, linear,internal compensation)TC-EL:(thermocouple, linear,external compensation)Type BType CType EType JType KType LType NType RType SType TType UType Txk/xk(l)You will find the digitized analog valuesin Section 4.3.1 in the temperature rangeof the SIMATIC Programmable LogicControllers S7 -300 Module Data ManualProduct Information S7 -300 Analog Input Module SM 331; AI 8 x TCA5E00455107-0119
