Parent Polymorphic VI: | HIL Read |
Requirements: | Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer |
Reads from an digital input channel of a HIL board.
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. |
digital channel is a channel number indicating the digital input channel to be read. The quantity read will appear at the digital state output. |
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. |
|||||||
digital state is the state read from the specified digital channel. |
|||||||
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.
|
This VI only reads one digital input. When reading from mixed signal types, it is more efficient to use the
All input/output pairs of this function have direct feedthrough behaviour.
