Owning Palette: | HIL/Core/Watchdog |
Requirements: | Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer |
Starts the watchdog timer. If the watchdog timer is allowed to expire then it resets all the outputs of the data acquistion cards to the programmed expiration states.
board in is a reference to a HIL Board instance that represents the open HIL board. This input must be wired to a valid HIL Board signal, as generated by a HIL Initialize VI. |
timeout in seconds is the timeout interval for the watchdog timer in seconds. The watchdog timer will expire after the given number of seconds if it is not reloaded before then. If it expires, then all the outputs of the data acquistion card are reset to the programmed expiration states. |
error in describes error conditions occurring before the VI executes. If an error has already occurred, the VI returns the value of the error in cluster in error out.
|
board out is a copy of the HIL Board instance passed to the board in input. |
|||||||
error out contains error information. If the error in cluster indicated an error, the error out cluster contains the same information. Otherwise, error out describes the error status of this VI.
|
The HIL Watchdog Start VI starts the watchdog timer so that it begins counting. The watchdog VIs are a safety feature used to shut down hardware in the event of software failure.
All input/output pairs of this function have direct feedthrough behaviour.

HIL Watchdog Clear | Clears the watchdog state of a HIL board. | |
HIL Watchdog Reload | Reloads the watchdog timer. If the watchdog had already expired then it does not clear the expiration state. The watchdog must be cleared in order to begin writing to the outputs again. |
