I have an integer array coming in via OPC UA I can see the value of the tag at this point, but I'm trying to make a reference tag that points to the integer array so that I don't have to do a huge amount of rebinding/script rewriting when the project goes live. My reference tag (part of a UDT) says uncertain when I point it to my OPC tag.

Does anyone know why my reference tag is not bringing the data in from the OPC tag?

Solved my own problem. I had my reference tag configured for clamping on 1 to 5 to control the possible values and it turns out that it didn't like that. After removing clamping the data is coming in fine.
