Ignition OPC and Siemens PLC tags

Hi,

I have succesfully installed the Ignition OPC Server UA and I can read data from a Siemens PLC (CPU315).
I have one question, how can I create tags in the OPC Server that are accessible /visible from any client? Because now I have to use the absolute address from the PLC to access the data. In the Designer I can create tags, but don’t show up in a external OPC client (like Simple OPC Client from Siemens). Does anyone know how to create such tags or what I’m doing wrong?

The Ignition OPC-UA Server has no support for custom tags, but you can always use the absolute address in other clients of course.

Hi,
Thanks for your reply.
So In other words, I can not define ‘symbolic’ tags in the server and use them in other OPC clients?

Yes, thats right. Symbolic tags are not supported with the Siemens Driver.
