The VI cannot access the XControl

This VI cannot use the XControl because the library access scope does not allow access to the XControl. The XControl is a private library item and only VIs in the same library or libraries contained in that library can access the XControl.

Complete the following steps to correct this error by changing access to the XControl from Private to Public.

1. In the Project Explorer window, right-click the XControl the VI cannot access and select Unlock Library for Editing.
2. Right-click the XControl again and select Access Scope»Public.
3. Right-click the XControl a third time and select Apply Changes to Instances. The Run button appears as a solid white arrow to indicate you can run the VI.
