Hello,

I have a question:

Do the node addresses in the OPC UA connection change when we rebuild the hardware? What conditions change node addresses?

Thank you.

Hello eceu

 in the NodeID you should find Namespace,Identifiert Type (Datatype) and Identifiert (symbolic name of tag in S7program)

so I would say if you change the symbolic address of a tag then also the Node ID should change
