2. Watchdog (WDT)
The effect of Watchdog is shown in the picture below.
Using method: First carry out setup. The mode is reset mode; counting unit can be
minute or second; timeout can be any figure within 1-255. After the setup is finished, press
“Start” button on the left, and Watchdog starts counting down. “Current time” shows the
current time for counting-down. Counting-down in reset mode means the PC reboots at 0.
During counting-down, “Feed Watchdog” button can be pressed to restart counting-down
from the set timeout time. Press “Stop” button to stop Watchdog. Exiting the program
when Watchdog is counting down will also stop Watchdog. If “Automatically feed
watchdog” option is selected, when the counted time is less than 3 seconds, Watchdog will
be automatically fed.
Function: Monitors whether the system can be normally operated, and carry out reset for
abnormality. When abnormality occurs to the system, Watchdog cannot be fed
automatically. After counting-down is finished, the system will restart, and recover from
system error.
