CL HIL Write PWM (Scalar)

Parent Polymorphic VI: CL HIL Write

Requirements: Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer, Control Design and Simulation Module

Description

Writes to a PWM channel of a HIL board.

Required Inputs All required inputs must be wired. They always appear as terminals on the VI palette. They also appear in bold text in the context help window for the VI.

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.

Recommended Inputs or Dialog Box Options Recommended inputs need not to be wired. They may be selected to appear as terminals or dialog parameters, but show up as terminals by default. They appear in simple text in the context help window for the VI.

PWM channel is a channel number indicating the PWM output channel to be written. The value written is the quantity at the PWM duty cycle or frequency input.

PWM duty cycle or frequency is the duty cycle (as a fraction between 0 and 1) or frequency (in Hertz) to write to the specified PWM channel.

Outputs

board out is a copy of the HIL Board instance passed to the board in input.

Details

This VI only writes one PWM output. When writing from mixed signal types, it is more efficient to use the CL HIL Write Mixed than to include multiple VIs specific to each type of channel.

Feedthrough Behaviour

All input/output pairs of this function have direct feedthrough behaviour.
