1.4 Watchdog
There are module watchdog and system watchdog in Wolf Series module.
Module watchdog is a hardware monitoring the operation status of module, when
working in a harsh/noisy environment and encountering interference, the module can
automatically reset and reboot by itself. The system watchdog is software monitoring
the operation status of system, its purpose is to provide immediate counter-measure
when erroneous network, communication or breakdown occur. Once time-out occurs,
the module will reset all outputs to SAFE mode to prevent any improper operations on
the controlled target.

system watchdog time-out will automatically start. Outputs mode is configurable on
certain modules. Please refer to Chapter 3 & Chapter4.
