Watchdog
The DataLab PC computers are equipped with hardware watchdog, which helps to in-
crease reliability in demanding applications. If the control program hangs (be it due to
critical error, infinite loop etc.), watchdog resets the computer and restores the initial
state.
It is necessary to activate the watchdog first. Then it checks for periodical signaling
from running application. If the application fails for some reason, watchdog resets the
computer. The period can be set with the step 0.1 s up to approx. 6,500 s. Application
deactivates the watchdog again upon its termination.
