HIL Write (Mixed)

Parent Polymorphic VI: HIL Write

Requirements: Quanser Rapid Control Prototyping Toolkit, LabVIEW 2020 or newer

Description

Writes to analog, digital, PWM and/or other channels of a HIL board.

Required Inputs All required inputs must be wired. They 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 Recommended inputs need not be wired. They appear as simple text in the context help window for the VI.

analog channels is an array of channel numbers indicating the analog input channels to be written. The voltages (or currents) written will appear at the analog voltages output.

PWM channels is an array of channel numbers indicating the PWM output channels to be written. The values written are those at the PWM duty cycles or frequencies input.

digital channels is an array of channel numbers indicating the digital input channels to be written. The quantities written will appear at the digital states output.

other channels is an array of channel numbers indicating the other input channels to be written. The values written will appear at the other values output.

analog voltages is the analog voltages (or currents) written to the specified analog channels.

digital states is the states written to the specified digital channels.

PWM duty cycles or frequencies is the duty cycles (as a fraction between 0 and 1) or frequencies (in Hertz) to write to the specified PWM channels..

other values is the values written to the specified other channels.

Outputs

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

Details

If any of the channels arrays are empty then those channels are not written. This VI allows a combination of different types of channels to be write at the same time. When mixed I/O operations are being performed, it is more efficient to use this VI than to include multiple VIs specific to each type of channel.

Feedthrough Behaviour

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

Examples

	RCP CL HIL Analog Loopback Example	This example is a simple analog loopback test, but it demonstrates a number of important features of RCP.
	RCP CL HIL Position Control Example	This example demonstrates how to use a PID controller to control Quanser's SRV02 experiment.
