CL HIL Read (Mixed)

Parent Polymorphic VI: CL HIL Read

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

Description

Reads from analog, digital, encoder and/or other channels 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.

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

encoder channels is an array of channel numbers indicating the encoder input channels to be read. The values read will appear at the encoder counts output.

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

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

Outputs

	board out is a copy of the HIL Board instance passed to the board in input.
	analog voltages is the analog voltages (or currents) read from the specified analog channels.
	encoder counts is the encoder counts read from the specified encoder channels.
	digital states is the states read from the specified digital channels.
	other values is the values read from the specified other channels.

Details

If any of the channels arrays are empty then those channels are not read. This VI allows a combination of different types of channels to be read 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.
