Hello all,

Can someone please help me figuring out what is happening with this hardware configuration?

I am testing an MRP ring using several PROFINET devices. In the images below you can see that I have a Wago bus coupler interfacing with two other bus couplers using WI-FI (I have two Access points and two Clients). These units are not part of the MRP ring, they can be thought of as wires that allow RIO34(remote device) to be part of the ring. I could not find a way to let TIA portal know that I am using a Wi-Fi connection instead of a wired one.

The PLC is the master in the MRP domain.

I tried (1) drawing cables in the “Topology View” between RIO34 bus coupler and the other two bus couplers, and (2) leaving these connections open and indicating “Any partner” as partner port, but both configurations cause errors. On the second one I get an error every one minute approximately.

I am using TIA portal V15.

Please let me know if you require more details and thank you for helping me out with this!

All my I/Os have the same Real time settings. Please see attached image.

I had to choose 128 ms update time to get an I/O watchdog time greater than 200 ms (MRP reconfiguration time, or time required to configure a new communication path after the MRP ring is interrupted).
