Profinet communication between UR20 and Beckhoff IPC

Hello everyone,
the PROFINET connection between my UR20 and the Beckhoff TwinCAT PLC is established, but I still cannot get the cyclic data exchange to work. So the link comes up, but no values are transferred, or not the ones I expect.

The robot and PLC are already networked and the device configuration is set up, but I’m stuck on the process data mapping.

Does anyone have a tip on what I should check on the TwinCAT side or on the UR side to get the I/O data exchange working?

Have you checked the permissions on the UR, in the hamburger menu?
