Protection relay REF630 lost communication with IEC61850 OPC Server
I'm an Automation Engineer. Our plant have some protection relay Ref630 at the substation connect to 800xA System via IEC61850 OPC Server. Recently, there's a failure REF630 with the screen and we have to replace by the new one. We did upload all the parameter by tool PCM600 ABB and downloaded to new device. The relay working well but the're an issue that we couldn't get communication between new device to OPC Server like before. Did I need any extra tool for fix this problem
Hi you can do the following checks,
1.First check whether you are able to ping the relay from IEC61850 connectivity sever.
2. In the relay check if the technical key is set as before. If there is mismatch in technical key between relay and the scd file uploaded in IEC61850 opc server then it will not communicate.
3. It could also be possible that the PCM600 backup restored is not having one or more datasets present in the scd file uploaded in the IEC61850 opc server. Any mismatch in the datasets will not communicate.
