Configure failover on OPC server state change

You can configure failover for cases where the OPC server leaves RUNNING state.

Navigate to the OPCInt > Failover > Server Level page, and check Failover if Server Leaves RUNNING State.

To configure a waiting period, set the Wait For RUNNING State field to the desired number of seconds. If the OPC server has not entered the RUNNING state before the specified period expires, PI Interface for OPC DA attempts to connect to the other server. If the other server has not entered the RUNNING state before the specified period expires, the interface retries the first server, alternating between the two until one is detected to be running again.
