Select Signals Express VI

Owning Palette: Signal Manipulation Express VIs

Requires: Base Development System

Accepts multiple signals as inputs and returns only the signals you select. You can specify which signals to include in the output and change the order of the input signals.

Parameter	Description
Select Signals	Contains the following options: Unselected signals—Lists all the input signals. The index number associated with each signal reflects the order of the input signals on the input wire. Selected signals—Lists the signals in the order in which you selected them. The original index number remains associated with the signal. If you wire the Selector Input input, the VI uses the signals that this input specifies instead. Select—Moves a signal from the Unselected signals list to the Selected signals list. Deselect—Moves a signal from the Selected signals list to the Unselected signals list. Sort—Sorts the signals in the Selected signals list in numerical order based on the index number.

Parameter

Description

Select Signals

Contains the following options:

Unselected signals—Lists all the input signals. The index number associated with each signal reflects the order of the input signals on the input wire.
Selected signals—Lists the signals in the order in which you selected them. The original index number remains associated with the signal. If you wire the Selector Input input, the VI uses the signals that this input specifies instead.
Select—Moves a signal from the Unselected signals list to the Selected signals list.
Deselect—Moves a signal from the Selected signals list to the Unselected signals list.
Sort—Sorts the signals in the Selected signals list in numerical order based on the index number.

Block Diagram Inputs

Parameter	Description
Signals	Contains the input signal or signals.
Selector Input	Selects which signals to include from the Signals input. This input can be a set of signals with the last point in each signal representing a true or false. When the last point in a signal represents true, the corresponding signal is included. This input also can be one signal, with each data point representing a true or false. Numeric values greater than or equal to 0.5 are true, and values less than 0.5 are false. If Selector Input is not wired, the VI uses the Selected signals specified in the configuration dialog box.
error in	Describes error conditions that occur before this node runs.

Parameter	Description
Signal Out	Returns the output signal.
error out	Contains error information. This output provides standard error out functionality.
