My OPC server's items have the OPC server node name included in the itemID, for example: serverA.AB_1234.PV. I have redundant OPC servers and redundant interfaces (in failover) and would like the tags to refer to the correct OPC address including when the OPC servers fail over. Currently the workaround is to create two sets of tags, each pointing to one OPC server's itemIDs in their instrument tags and then merge the data with AF or a PE.
