Watchdog timer and emergency stop was created by csar4231
Hi, I would like to put the emergency stop command ( !EX) when watchdog timer is triggered. I have read that it is possible with a script,
Do you have an example?
Thanks

Hi,
I am afraid this is not possible via script. There is no interface to let you know whether the controller watchdog has expired.
I would suggest to make a keep-alive mechanism using the scripting. By sending the motor command, send also a counter value in VAR 1 and validate via script using a counter there as well.

I am also looking for a way to apply an emergency stop in reaction to the watchdog timer. So that if the controller begins a PID operation and stops receiving serial commands before finishing, the emergency stop is engaged. This is important for safety in the event of a program error or disconnected computer.
Is there any formula for this other than building another deadman switch system that cuts the power to the controller?

I'm likewise searching for a method for applying a crisis stop in response to the guard dog clock. So that assuming the regulator starts a PID activity and quits getting sequential orders prior to getting done, the crisis stop is locked in. This is significant for well-being in case of a programming mistake or disengaged PC.
Is there any recipe for this other than building another deadman change framework that slices the capacity to the regulator?
