If your Universal Robots robotics system loses communication with the controller, it could be due to interference with the communication. First, check the Ethernet cable between the Control Board and Motherboard, ensuring that no script or UR+ software is overloading the communication. Next, inspect the cable between the controller and the robot. Perform a complete rebooting sequence and consider updating the software.
