Command
RWD
Description
The Reset Watchdog command restores the controller to an operating condition from a latched Watchdog Has Tripped shutdown condition. If the conditions that caused the watchdog to trip are not remedied before Reset Watchdog is used then Reset Watchdog will escape. The Initialize procedure in the standard.inc library calls Reset Watchdog when the program first starts. There should only be a need to use this command if the EStop signal can be tripped during machine operation.
Escapes
If the conditions that caused the watchdog to trip are not remedied, ResetWatchdog will generate a Watchdog Failed To Reset Escape Code.
Examples
This command list shows that the watchdog has been tripped by an EStop condition. An attempt to reset the watchdog fails because the EStop has not been satisfied. After restoring the EStop circuit the reset watchdog command succeeds.
