A support ticket is open for this, perhaps someone else has experienced this and can assist. Version 7.9.13 On the production system a UDT has an OPC tag pointing to device “PLC\_NEW”. When a new gateway backup is restored this UDT changes such that the OPC tag points to device “PLC\_OLD”. The UDT was modified a couple years ago. The gateway backup was made on the production system but restored on a development system. This issue was discovered during a test of gateway redundancy, the UDT also reverted to the old definition sometime during either the fail over to the backup node or back to the primary node. ---
