HI

I have had a project running for a few weeks and twice it has shut the program down due to this exception.

exception[ProcessorLoadWatchdog] occurred in: App=[all], Task[all]

I have to reboot (power cycle) the system to clear the exception. or remotely restart the application.

Any ideas?

Cheers

👍

Which plc is this - seems that the performance of this device is not enough.
You could check the plcload in the plcshell by 'plcload'

  Its Running on a Weintek CMT HMI.
  the program is not huge, just controlling a few pumps.
  plc is at 1%

Same here. plcload in my case is about 7% while running.
Watchdog ENIPScannerIOTask was about 200ms. Max cycle around 6ms, normal cycle time 4ms.

Probably just increase the watchdog to 2000ms? or so...

The Weintek HMI Runs a dual core CPU.. one for the HMI and one "real time OS" for Running Codesys.
