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.
