Hi,

I am currently trying to set up communication between a Codesys PLC (RaspberryPi) and a Universal Robot UR5e via Profinet.

The integration of the robot works without any problems. The problem currently is the use of the registers to transfer values from the PLC to the robot.
As soon as the "O2T" registers (O2T : PLC output to Robot input) are activated, I get the error message shown in the figure and the communication breaks down again and again. If the "O2T" registers 8-10 are deactivated, the connection works without problems.
Since the error message refers to the Profinet configuration on the robot, I checked the settings. Also there an error message is displayed if one or more of the O2T registers are enabled in the PLC:

"Could not enable I/O device module to control registers. Registers may be controlled by another device."

Does anyone have a tip on what I need to configure so that the O2T registers can be used?

Thanks in advance!
