Hi, I am afraid that I can't help with TIA Portal, but if you have successfully set up an AXC F x152 controller as a Profinet device, then you will be able to read and write data to these system variables in the PLCnext Control device:

(the screen shot is from PLCnext Engineer).

You will need to create your own PLCnext Engineer project that (a) configures the Axioline I/O modules that are connected to the PLC, and (b) copies the process data between the Axioline I/O modules and the two PND_S1 arrays shown in the above screen shot.

If the aim is to simply treat the Axioline I/O as remote Profinet I/O for the Siemens PLC (without any other logic in the PLCnext Control device), then it would be simpler to use a Profinet Bus Coupler rather than a PLC as the interface to the Axioline I/O.

I hope this helps.

Yes, that's all that is needed. This will be a relatively simple PLCnext Engineer project, but if you need further help please let us know.
