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 second watchdog will have 255000

max timeout, 1000 min timeout, and 1000 timeout steps. You can test the functional-

ity 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, it can be reset by clicking the REFRESH

button. After clicking this button, the Timeout Countdown field will display the

value of the SET TIMEOUT field.

 If you want to stop the watchdog timer, just click the STOP button.
