Read VI

Owning Palette: Digital Input/Output 1 Sample VIs

Requires: myRIO Toolkit, roboRIO Toolkit, or NI ELVIS RIO Control Toolkit

Reads the logic levels of one or more digital I/O channels.

	DIO Ref In specifies the reference to the digital I/O channels from which to read logic levels. Use the Open VI to open a reference to the digital I/O channels. Do not modify the DIO Ref In values.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	DIO Ref Out returns the reference to the digital I/O channels from which this VI reads logic levels.
	Values returns the logic levels that this VI reads from the digital I/O channels. Values returns TRUE if the logic level is a high voltage and returns FALSE if the logic level is a low voltage. The direction of a channel changes to input before this VI reads the logic level. The order of the elements in Values corresponds to the order in which the Open VI opens the digital I/O channels.
	error out contains error information. This output provides standard error out functionality.
