I have set up a primary and failover backup of Ignition based OPC-UA computers. The question is: how do we know if we have failed over to the backup computer, and can it be set up so a plant operator can reset the pair back to the primary system through a SCADA screen?
Great, but the orignial request was to get a status to know when the OPC connection is using FailOver or not and also a way to return to the primary connection when available !
