You can insert an input or output terminal into the expandable field of a subVI or Express VI. The terminals you can insert depend on the inputs and outputs the subVI or Express VI includes. For example, you must first assign a front panel control or indicator to the connector pane of a subVI before you can insert the control or indicator into the expandable field of the subVI.

Complete the following steps to insert an input or output in a subVI or Express VI.

  1. Display the subVI or Express VI as an expandable node.
  2. Right-click an input or output in the expanded field of the subVI or Express VI and select Insert Input/Output from the shortcut menu. A new input or output terminal appears above the input or output you right-clicked.

To remove an input or output, right-click the terminal you want to remove and select Remove Input or Remove Output from the shortcut menu.
