4.3.4.8 Watchdog
When the application is executed, it will display watchdog information in the WATCH-
DOG INFORMATION group box. It displays max timeout, min timeout, and timeout
steps in milliseconds. For example, a 1~255 seconds watchdog will has 255000 max
timeout, 1000 min timeout, and 1000 timeout steps. You can test the functionality of
the watchdog as follows:
Set the timeout value 3000 (3 sec.) in the SET TIMEOUT field and set the delay
value 2000 (2 sec.) in the SET DELAY field, then click the START button. The
Timeout Countdown field will countdown the watchdog timer and display 5000
(5 sec.).
Before the timer counts down to zero, you can reset the timer by clicking the
REFRESH button. After you click this button, the Timeout Countdown field will
display the value of the SET TIMEOUT field.
If you want to stop the watchdog timer, you just click the STOP button.
