6.3. CommunicationcharacteristicsCompact NS100 to 630053172siIn shortIntegration of the circuit breaker or theswitch-disconnector in a supervisonsystem requires either the communicatingauxiliaries or the SC150 interface.Compact devices fit perfectly in the SMSPowerlogic electrical installationmanagement system by communicatingusing Digipact protocols. An externalgateway offers communication via othernetworks including:b Profibusb Ethernet…There are two possibilities for the 100 to 630 A range:b communicating auxiliariesThey replace the standard auxiliaries and connect directly to the Digipact bus.Three equipment levels:v communicating auxiliary contacts, comprising:- OF (on/off), SD (trip indication) and SDE (fault-trip indication) contacts- electronic module- prefabricated wiring.v communicating auxiliary contacts and motor-mechanism module, comprising:- OF (on/off), SD (trip indication) and SDE (fault-trip indication) contacts- motor-mechanism module (220 V AC) (1)- electronic module- prefabricated wiring.v communicating carriage switches for the chassis, comprising:- CE / CD (connected/disconnected position) contacts- electronic module- wiring connector.b SC150 interfaceUsing the SC150 interface, it is possible to integrate a device equipped with noncommunicatingauxiliaries into a supervison system.The SC150 interface is used to connect:v the auxiliary contacts on the circuit breaker (OF, SD, SDE, SDV, CD, CE)v the remote-operation system (on, off, reset)v the communication output for the STR53UE and STR43ME electronic trip unitsequipped with the COM optionv an unassigned digital input.054481si054516siCompact NS equipped with communicating auxiliary contactsand motor-mechanism module.Withdrawable Compact NS on its chassis equipped withcommunicating auxiliary contacts.Compact withcommunicating SC150auxiliariesdevice identificationaddress b brating - -indication of status conditionsOF (on/off) b bSD (trip indication) b bSDE (fault-trip indication) b bCE/CD (connected/disconnected position) b bcontrolsON/OFF b bLED reset b b<strong>protection</strong> settingsReading of the <strong>protection</strong> settingsoperating and maintenance aidsMeasurements:currentsbFault readings:type of faultbIndications:operation counter b b(1) For voltages other than 220 V AC, use a standard motor-mechanism module (noncommunicating)together with an SC150 indication and control interface.bSC150 indication and control interface.71
CTCDCE6.3. CommunicationcharacteristicsMasterpact NT / NW056431siIn shortThe COM option is required forintegration of the circuit breaker or switchdisconnectorin a supervision system.Masterpact uses the Digipact or Modbuscommunications protocol for fullcompatibility with the SMS PowerLogicelectrical-installation managementsystems. An external gateway is availablefor communication on other networks:b Profibusb Ethernet…Digipact "device"communication module.For fixed devices, the COM option is made up of:b a "device" communication module, installed behind the Micrologic control unitand supplied with its set of sensors (OF, SDE ,PF and CH micro-contacts) andits kit for connection to XF and MX communicating voltage releases.For drawout devices, the COM option is made up of:b a "device" communication module, installed behind the Micrologic control unitand supplied with its set of sensors (OF, SDE, PF and CH micro-contacts) andits kit for connection to XF and MX communicating voltage releasesb a "chassis" communication module supplied separately with its set of sensors(CE, CD and CT contacts).Status indication by the COM option is independent of the device indicationcontacts. These contacts remain available for conventional uses.Digipact or Modbus "Device" communication moduleThis module is independent of the control unit. It receives and transmitsinformation on the communication network. An infra-red link transmits databetween the control unit and the communication module.Consumption: 30 mA, 24 V.Digipact or Modbus "chassis" communication moduleThis module is independent of the control unit. With Modbus "chassis"communication module, this module makes it possible to address the chassisand to maintain the address when the circuit breaker is in the disconnectedposition.Consumption: 30 mA, 24 V.XF and MX communicating voltage releasesThe XF and MX communicating voltage releases are equipped for connection tothe "device" communication module.The remote-tripping function (second MX or MN) are independent of thecommunication option. They are not equipped for connection to the "device"communication module.056401siDigipact "chassis"communication module.E88758Ecommunicationbus2CCM modbus+ ++OFSDEPFCHCDCCTMXXFCE45056431siModbus "device"communication module.13E45183siModbus "chassis"communication module.1 "Device" communication module : hard wire2 "Chassis" communication module : communication bus3 OF, SDE, PF and CH "device" sensors4 CE, CD and CT "chassis" sensors5 MX and XF release.Note:Eco COM is limited to the transmission of metering data and does not allow thecontrol of the circuit breaker.72
