AC800M OPC server , Controller status showing Down (Not Communicating)
Hi
Redundant AS , CS , MMU , IM server's with 2 Operator station and single EWS.
AS we have redundant Connectivity server configuration . It was running fine , and suddenly all Operator station shows red cross (No data) . When I check OPC communication with controllers, it was all RED (not communicating) .
From CS , i ping all controllers and network was fine .But in OPC , it's not browing any controller's (via Available Controllers) .
Also , OPC service was restarted , it was set on auto load configuration , but still no communication.
Can you please guide me to right path to start troubleshooting .
Thanks in advance.

OK, so what did you change ? Or what Changed ?
Check your event logs and RNRP logs for ANYTHING that happened at the same time. eg, network card failed, server booted, one network connection lost etc.
Ensure that RNRP is correctly configured on the Control Network and that the RNRP status window can see all controllers on both networks.
Check the OPC Server error logs in C:\ABB Industrial IT Data\OPC Server for AC800M\Log Files.
If the controllers are still showing Red X on the OPC Server control panel then you can try disconnect / reconnecting to a controller to see if Reloading the config files from Control Builder helps. If this does not resolve the problem then I would not recommend trying another controller.
