S7-300 send data to PC with Ignition/OPC-UA

hi Kevin, thanks for your support.

the problem is exactly there : what is the nodeID format accepted by the Siemens Driver module that can be passed to S7 protocol ?

I’ve attached a capture of what I see with both the Ignition server and the Simatic opc ua server.
could you give me a hint on this right nodeId thing please?
thanks again
Eric
