	error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.
	watchdogID out has the same value as watchdogID in.
	watchdog status is the current status of the watchdog timer. The watchdog status output can return the following values: disabled Indicates that the watchdog object is disabled. expired Indicates that the watchdog object has expired. running Indicates that the watchdog object is running normally.
	error out contains error information. This output provides standard error out functionality.

Watchdog Whack Details

If the countdown of the watchdog timer has not yet started, this VI starts the countdown. If the watchdog object is running or disabled, this VI restarts the countdown of the watchdog timer. If the watchdog object is expired, this VI restarts the countdown of the watchdog timer only if you set reset watchdog after expire? to TRUE.

Example

Refer to the Watchdog Reset - RT Engine VI in the labview\examples\Real-Time\RT Watchdog (PXI).llb for an example of using the Watchdog Whack VI.
