To change the watchdog timeout value, go to the Project Brower and right click on the MAST, FAST or AUX directory and choose <Properties>. The following box appears:
The Watch Dog timeout value must be greater than the period value (specified time in which the master task must be executed).
System Bit %S11 indicates watchdog overflow. This bit is set to 1 when the task execution time becomes greater than the maximum execution time (watchdog timout value).
