PC Watchdog Timer Management Function
Section 3-11
Note
The Board’s PC watchdog timer function is disabled when the Board starts
operation. It is also disabled by the SCAN_Reset() function.
When using the PC watchdog timer function, execute the SCAN_Enable
PCWDTTimer() to enable the PC watchdog timer and refresh the timer value.
If the timer isn’t refreshed, the function will determine that the application has
stopped and will stop remote I/O communications if the set time has elapsed
since the last refresh.
