IEC61850 alarms from OPC Server retriggered when redundant server is restarted/shutted down
I'm working on a project where we have IEC61850 communication from some Siemens and Schneider relays to our two IEC61850 OPC Server (CET600), and from there to 800xA. The communication itself works fine.
The problem arrives, when one of our redundant servers are restarted or shutted down. When we do this, the active alarms are retriggered, hence needs to be acknowledged again. Furthermore some old alarms with old timestamps shows up in the alarm list (in 800xA) in the RTN state. The case is the same for both the values comming from Siemens and Schneider relays.
Have some of you experienced this before, or know how to solve this problem?
Thanks for the answers in advance.
