Select Signals

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.

Dialog Box Options


Option	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.

Inputs/Outputs

Signals —

Contains the input signal or signals.

error in (no error) —

Describes error conditions that occur before this node runs.

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.
