16. Station communicationOverviewEach IED is provided with a communication interface,enabling it to connect to one or many substation levelsystems or equipment, either on the Substation Automation(SA) bus or Substation Monitoring (SM) bus.Following communication protocols are available:• IEC 61850-8-1 communication protocol• LON communication protocol• SPA or IEC 60870-5-103 communication protocol• DNP3.0 communication protocolTheoretically, several protocols can be combined in the sameIED.IEC 61850-8-1 communication protocolThe IED is equipped with single or double optical Ethernetrear ports (order dependent) for IEC 61850-8-1 station buscommunication. The IEC 61850-8-1 communication is alsopossible from the optical Ethernet front port. IEC 61850-8-1protocol allows intelligent electrical devices (IEDs) fromdifferent vendors to exchange information and simplifiessystem engineering. Peer-to-peer communication accordingto GOOSE is part of the standard. Disturbance files uploadingis provided.Serial communication, LONExisting stations with ABB station bus LON can be extendedwith use of the optical LON interface. This allows full SAfunctionality including peer-to-peer messaging andcooperation between existing ABB IED's and the new IED670.SPA communication protocolA single glass or plastic port is provided for the ABB SPAprotocol. This allows extensions of simple substationautomation systems but the main use is for SubstationMonitoring Systems SMS.IEC 60870-5-103 communication protocolA single glass or plastic port is provided for theIEC60870-5-103 standard. This allows design of simplesubstation automation systems including equipment fromdifferent vendors. Disturbance files uploading is provided.DNP3.0 communication protocolAn electrical RS485 and an optical Ethernet port is availablefor the DNP3.0 communication. DNP3.0 Level 2communication with unsolicited events, time synchronizingand disturbance reporting is provided for communication toRTUs, Gateways or HMI systems.Multiple command and transmitWhen 670 IED's are used in Substation Automation systemswith LON, SPA or IEC60870-5-103 communication protocolsthe Event and Multiple Command function blocks are used asthe communication interface for vertical communication tostation HMI and gateway and as interface for horizontal peer-to-peer communication (over LON only).IEC 62439-3 Parallel Redundant ProtocolRedundant station bus communication according to IEC62439-3 Edition 1 and IEC 62439-3 Edition 2 are available asoptions in 670 series IEDs. IEC 62439-3 parallel redundantprotocol is an optional quantity and the selection is made atordering. Redundant station bus communication according toIEC 62439-3 uses both port AB and port CD on the OEMmodule.Select IEC 62439-3 Edition 1 protocol atthe time of ordering when an existingredundant station bus DuoDriver installationis extended.Select IEC 62439-3 Edition 2 protocol atthe time of ordering for new installationswith redundant station bus.IEC 62439-3 Edition 1 is NOT compatiblewith IEC 62439-3 Edition 2.17. Remote communicationAnalog and binary signal transfer to remote endThree analog and eight binary signals can be exchangedbetween two IEDs. This functionality is mainly used for theline differential protection. However it can be used in otherproducts as well. An IED can communicate with up to 4remote IEDs.Binary signal transfer to remote end, 192 signalsIf the communication channel is used for transfer of binarysignals only, up to 192 binary signals can be exchangedbetween two IEDs. For example, this functionality can beused to send information such as status of primaryswitchgear apparatus or intertripping signals to the remoteIED. An IED can communicate with up to 4 remote IEDs.Line data communication module, short and medium rangeLDCMThe line data communication module (LDCM) is used forcommunication between the IEDs situated at distances <110km or from the IED to optical to electrical converter with G.703 or G.703E1 interface located on a distances <3 kmaway. The LDCM module sends and receives data, to andfrom another LDCM module. The IEEE/ANSI C37.94 standardformat is used.Galvanic interface G.703 resp G.703E1The external galvanic data communication converter G.703/G.703E1 makes an optical-to-galvanic conversion forconnection to a multiplexer. These units are designed for 64kbit/s resp 2Mbit/s operation. The converter is delivered with19” rack mounting accessories.Bay control REC670 1MRK511232-BEN EPre-configuredProduct version: 1.2ABB 19
