OPC UA Server not accessing IRC5 controller tags

When I use the OPC UA Server with a virtual controller, I have no issues accessing data tags within the IRC5 controller.  When I connect to an actual robot, I'm unable to access the IRC5 data nodes.  I see "MonitoredItem.MonitoredItem - Connect error: BadNodeIDUnknown "Error creating monitored item on the server.  BadNodeIdUnknown"  Please let me know if you have any suggestions.  Thank you.

  • I have exactly the same problem (but with a virtual controller). Could you solve the problem?
