You can create a subVI from an Express VI configuration. For example, you might want to save the configuration of the Write To Measurement File Express VI for use as a subVI in other VIs you build rather than reconfiguring the Express VI every time. Right-click the Express VI and select Open Front Panel from the shortcut menu to create a subVI from an Express VI.

When you create a subVI from an Express VI, the front panel of the subVI appears. You then can edit the VI and save it. To save the values entered in controls, select Edit»Make Current Values Default or right-click each control and select Data Operations»Make Current Value Default from the shortcut menu. A new subVI displayed as an expandable node replaces the Express VI on the block diagram.

After you create a VI from an Express VI, you cannot convert the subVI back into an Express VI.
