Dear All,
we encounter problem on flex pendant cannot communicate with the controller. we suspects that there is a problem on the main computer device net card. The cable of the flex pendant is tested for continuity but proved
negative for short or cut line.
Upon checking the controller, axis computer LED is flashing in red
There is also error on the Machine's HMI that is connected to the controller that there is something wrong with the devicenet
As of now, the robot is down due to the problem.
can anyone please advise actions we need to do to isolate the problem and determine the root cause.
Or any action to provide solution for this problem.
Thanks.
