16. CommunicationThe IED supports a range of communicationprotocols including IEC 61850, IEC60870-5-103, Modbus® and DNP3.Operational information and controls areavailable through these protocols.The IEC 61850 communicationimplementation supports all monitoring andcontrol functions. Additionally, parametersetting and disturbance file records can beaccessed using the IEC 61850 protocol.Disturbance files are available to any Ethernet-based application in the standardCOMTRADE format. Further, the IED cansend and receive binary signals from otherIEDs (so called horizontal communication)using the IEC61850-8-1 GOOSE profile. TheIED meets the GOOSE performancerequirements for tripping applications indistribution substations, as defined by theIEC 61850 standard. The IED cansimultaneously report events to five differentclients on the station bus.All communication connectors, except for thefront port connector, are placed on integratedoptional communication modules. The IEDcan be connected to Ethernet-basedcommunication systems via the RJ-45connector (100BASE-TX) or the fibre-optic LCconnector (100BASE-FX).Modbus implementation supports RTU, ASCIIand TCP modes. Besides standard Modbusfunctionality, the IED supports retrieval oftime-stamped events, changing the activesetting group and uploading of the latest faultrecords. If a Modbus TCP connection is used,five clients can be connected to the IEDsimultaneously. If required, both IEC 61850and serial Modbus protocols can be runsimultaneously.The IEC 60870-5-103 implementationsupports two parallel serial bus connectionsto two different masters. Besides basicstandard functionality, the IED supportschanging of the active setting group anduploading of disturbance files in IEC60870-5-103 format.DNP3 supports both serial and TCP modesfor connection to one master.When the IED uses the RS-485 bus for theserial communication, both two- and fourwire connections are supported. Terminationand pull-up/down resistors can be configuredwith jumpers on the communication card soexternal resistors are not needed.The IED supports the following timesynchronization methods with a time-stamping resolution of 1 ms:Ethernet based:• SNTP (Simple Network Time Protocol)With special time synchronization wiring:• IRIG-B (Inter-Range Instrumentation Group- Time Code Format B)In addition, the IED supports timesynchronization via the following serialcommunication protocols:• Modbus• DNP3• IEC 60870-5-103Transformer Protection and Control 1MRS756891 BRET615Product version: 2.0 Issued: 01.10.2009ABB 15
