Section 10 Establishing connection and verifying theIEC 61850 communication10.1 Overview SEMOD172103-4 v8The rear optical Ethernet ports are used for:• process bus (IEC/UCA 61850-9-2LE) communication• IEEE C37.118/1344 communication• substation bus (IEC 61850-8-1) communication10.2 Setting the station communication SEMOD172108-3 v12To enable IEC 61850 communication the corresponding ports must be activated.The rear access points can be used for IEC 61850-8-1 and IEC/UCA 61850-9-2LEcommunication. IEC 61850-8-1 redundant communication requires the use of twoEthernet ports, when it is activated for Ethernet port the next immediate port isselected as the second Ethernet port and will become hidden.To enable IEC 61850 station communication:In this example access points 1, 2 and 3 are used.1. Activate IEC 61850-8-1 (substation bus) communication.Navigate to: Main menu/Configuration/Communication/Stationcommunication/IEC61850–8–1/IEC61850–8–1:12. Enable operation for Access Point 1 and 3 in the Ethernet configuration tool(ECT) in PCM600.3. Enable redundant communication for Acess point 1 using ECT.4. Enable IEC/UCA 61850-9-2LE (process bus) communication for Accesspoint 3 by connecting it to a Merging unit in the Merging units tab in ECT.There are no settings needed for the IEC/UCA 61850-9-2LE communication in thelocal HMI branch Station communication. Make sure that the optical fibres areconnected correctly. Communication is enabled whenever the merging unit startssending data.1MRK 502 073-UEN A Section 10Establishing connection and verifying the IEC 61850 communicationGenerator protection REG670 2.2 IEC and Injection equipment REX060, REX061, REX062 99Commissioning manual
