This error occurs when an attempt is made to reset the watchdog safety system and it fails to reset. The safety system requires a signal be present
on the Estop input to permit motion and this signal is not present. If the system has an EStop switch confirm that the EStop button is not pushed. If the
system is not using an EStop circuit then the EStop input must be satisifed with a loopback.
If Reset Watchdog is being used without a Try Recover the problem will not be handled by the application.
If there is an EStop button being used with the EStop input use a try recover block to catch the error and indicate to the operator the need to release the estop.
