RobotMonitor/MOVI-C^® CONTROLLER communication breaks off repeatedly (timeout)

The RobotMonitor might time out if it is used on devices with poor performance, such as an old engineering PC or a mobile panel whose focus is on robustness rather than performance. This means that while the RobotMonitor has access to the robot, the robot performs an emergency stop and the brakes of the robot axes are applied.

Remedy

To be able to use the RobotMonitor also on devices with low performance, the timeout time can be increased. The INPUT variable tTimeOut of the HMI module can be used to specify the time after which a timeout is detected and the robot is stopped. The default value for the timeout time is 1.5 s. A timeout time of 4 s has proven to be practicable on the devices described.

The timeout time can be assigned in the User_PRG.Init action:

HMI_SoftwareNode.tTimeOut := T#4S;

If the communication is not stable even after having increased the timeout time, contact SEW‑EURODRIVE Service.
