What are the conditions for Ignition`s OPC client to switch to Failover OPC UA server: OPC Server Fault Only? and does it support OPC UA Server Redundancy Standard i.e, Does the ignition verify the Service Level system variable to determine the state of the OPC server?
Thanks
It checks the connection state every 5 seconds and if the number of times it checked and found it wasn't connected exceeds the configured failover threshold it switches to the other server.
No, neither Ignition's OPC UA client nor server know anything about OPC UA redundancy.
