Adding some clarity here for the Inductive folks. Redundant Schneider OPC servers currently use the ServiceLevel tag value. Ignition's OPC server does the exact same thing so that clients know which server to treat as the master (New in 8.1.10).
Without this feature, Igntion as an OPC client can end up connected to a Schneider OPC server with a lower ServiceLevel tag. If this happens Ignition will not be able to write to the server
