I have a project running on one machine that I am trying to move to another.

Made a backup of the gateway, restored successfully. OPC server is running and connected. SQL database is running and connected.

All of my OPC tags have the green overlay with quality unknown. This also occurs if I attempt to drag a tag over from the OPC server.

Suggestions?

Andy
