<div class="markdown_content"><p>Hi,</p> <p>I am currently trying to set up communication between a Codesys PLC (RaspberryPi) and a Universal Robot UR5e via Profinet.</p> <p>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.<br/> 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.<br/> 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:</p> <p>"Could not enable I/O device module to control registers. Registers may be controlled by another device."</p> <p>Does anyone have a tip on what I need to configure so that the O2T registers can be used?</p> <p>Thanks in advance!</p></div>
