OPC tags giving Error Configuration

Ignition
1

Hello all,

I have a UDT where I am trying to read a value. Value is in a user data type embedded in an add on instruction in Logix Designer. The UDT in Ignition (8.1.7) does not work, but when I create a single tag I can drill down to the values I need. The single tag version and the UDT instance have the same OpcItemPath.

UDT instance:

Do the Tag Diagnostics give you any more info, like maybe the OPC server you specified doesn’t exist?

You are missing the value of “OpcServer” in your UDT.

Thank you!
I was missing the OPC server in the UDT. :blush:
