Station communicationThe IED supports a range of communicationprotocols including IEC 61850, IEC 60870-5-103,Modbus® and DNP3. Operational information andcontrols are available through these protocols.However, some communication functionality, forexample, horizontal communication between theIEDs, is only enabled by the IEC 61850communication protocol.The IEC 61850 communication implementationsupports all monitoring and control functions.Additionally, parameter settings, disturbancerecordings and fault records can be accessedusing the IEC 61850 protocol. Disturbancerecordings are available to any Ethernet-basedapplication in the standard COMTRADE fileformat. The IED supports simultaneous eventreporting to five different clients on the stationbus.The IED can send binary signals to other IEDs (socalled horizontal communication) using the IEC61850-8-1 GOOSE (Generic Object OrientedSubstation Event) profile. Binary GOOSEmessaging can, for example, be employed forprotection and interlocking-based protectionschemes. The IED meets the GOOSEperformance requirements for trippingapplications in distribution substations, as definedby the IEC 61850 standard. Further, the IEDsupports the sending and receiving of analogvalues using GOOSE messaging. Analog GOOSEmessaging enables fast transfer of analogmeasurement values over the station bus, thusfacilitating for example sharing of RTD inputvalues, such as surrounding temperature values,to other IED applications.For a self-healing Ethernet solution the IED offersan optional fibre-optic communication moduleproviding two optical and one galvanic Ethernetnetwork interfaces. Alternatively, the IED featuresan optional galvanic communication module withtwo galvanic and one optical Ethernet networkinterfaces or three galvanic interfaces. The thirdEthernet interface provides connectivity of anyother Ethernet devices to an IEC 61850 stationbus inside of a switchgear bay.The self-healing Ethernet ring solution enables acost efficient communication ring controlled by aTransformer Protection and Control 1MRS756891 FRET615Product version: 4.022 ABB
