Folks, is there a way to do symbolic addressing of nodes in the S7-1500 Server Interface? (same question for S7-1200).

If I enable the Standard Server Interface in the S7-1500 OPC server, I can browse the entire PLC with OPC client and the node ID comes up as "xxx"."xxx" syntax when I browse with a client.

If I create a Server Interface, any tag I add in to it only seems to come up as a node ID in the client.
I did try to use the same syntax in the index 3 namespace, but it doesn't seem to like it.

Reason being is I am trying to add an OPC connection from a client in my SCADA however I would rather not allow full R/W access to the PLC as only a few tags need to be used in the scada.

I could still use the node IDs, but there is risk that if I change the structure in the server interface that the node IDs shift, then the scada connection is no longer correct.

You are correct, I was configuring via Tia portal.

This is spot on what I was looking for, thank you!
