3 PROFIBUS PAIFC 300For both replacements 1. and 2., there are 2 options how to deal with the GSDs. In order toprovide communication between "IFC300 with PROFIBUS MBP interface" and the PLC, you may -in principle – use the GSD of the "IFC090PA" ("KROHF401.GSD" or "YP01F401.GSD") and–alternatively - the GSD of the "IFC300 with PROFIBUS MBP interface" ("KR024501.GSD" or"YP024501.GSD").However, both sets of GSDs, when applied, do not provide the same level of functionality in thePLC. The available PROFIBUS functionality of the "IFC300 with PROFIBUS MBP interface" in thePLC as function of installed flow sensor and GSD used for integration into the PLC is as follows:Installed flow sensorIntegration into the PLC viaIFS…FLUX flow sensor(Option 1.)IFC090PA.GSDKROHF401.GSD"IFC090PA" profile 2 functionalityIFC300 with PROFIBUS MBPinterface GSDKR024501.GSDIf the GSDs of the "IFC090PA" ("KROHF401.GSD" or "YP01F401.GSD") are used…• The IFC090PA parameter set for the PLC control software will be maintained, i.e. there is noadaptation needed with reference to the replaced interface of the IFC300 with PROFIBUSMBP interface.• In this usage of the GSD the PA Profile 2.0 functionality is provided in the PLC for bothreplacements, i.e. it is not possible to reset the PA totalizer via the PLC.If the GSD of "IFC300 with PROFIBUS MBP interface” (KR024501.GSD orYP024501.GSD) is used…"IFC300 with PROFIBUS MBPinterface" functionality (some"IFC300 with PROFIBUS MBPinterface" self-test functions notavailable)OPTIFLUX flow sensor (Option 2.)

IFC 300APPLICATION PROFILE 44.1 Function blocksThe PROFIBUS MBP interface is based on the PROFIBUS PA Profile Version 3.0 and supports thefollowing blocks:• 1 physical block.This block contains the parameters defined in PA Profile 3.0.• 1 transducer block for electromagnetic flow devices.This block provides the parameters and functions defined in PA Profile 3.0.• 5 Analog Input (AI) function blocks.As default: Volume Flow / Mass Flow / Speed Flow / Coil Temperature / Conductivity.• 3 totalizer (TOT) function blocks.As default the first two totalizers will totalize volume and the third one will totalize mass.4.2 Data structure of function block output valuesThe data structure of function block outputs consists of 5 bytes: a 4 byte float value (Float Formataccording IEEE Standard 754 Short Real Number) followed by a 1 byte status value. If all 8function block outputs have been configured (see above), 40 bytes will be transmitted.4.2.1 Float valueExample of float formatByte n Byte n+1Bit7 Bit6 Bit7 Bit6VZ 2 7 2 6 2 5 2 4 2 3 2 2 2 1 2 0 2 -1 2 -2 2 -3 2 -4 2 -5 2 -6 2 -7ExponentMantissaByte n+2 Byte n+3Bit7Bit72 -8 2 -9 2 -10 2 -11 2 -12 2 -13 2 -14 2 -15 2 -16 2 -17 2 -18 2 -19 2 -20 2 -21 2 -22 2 -23MantissaMantissaExample (binary): 40 F0 00 00 (hex) = 0100 0000 1111 0000 0000 0000 0000 0000Formula:value = (-1) VZ * 2 (Exponent – 127) * (1 + Mantissa)value = (-1) 0 * 2 (129 – 127) * (1 + 2 -1 + 2 -2 + 2 -3 )value = 1 * 4 * (1 + 0.5 + 0.25 + 0.125)value = 7.502/2011 - 4001086601 - AD IFC 300 PROFIBUS R01 enwww.krohne.com25
