Requirements: | Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer |
Indicates whether the watchdog timer has expired and the board is now in the watchdog state in which outputs cannot be written.
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. |
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. |
|||||||
expired is a boolean scalar that is true if the watchdog has expired and false otherwise. |
|||||||
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 Is Expired VI may be used to determine if the watchdog has expired without reloading the watchdog. The HIL Watchdog Reload VI reloads the watchdog and also outputs whether the watchdog has expired, so it is generally more useful.
All input/output pairs of this function have direct feedthrough behaviour.
There are currently no examples
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. | |
HIL Watchdog Clear | Clears the watchdog state of a HIL board. |
