Returns a reference to the variable the referenced project item references. If the referenced project item is not a variable item, this property returns Not a Refnum. You can use this reference with the Variable properties to configure shared variables programmatically.

Note You can create, configure, and host shared variables only on Windows or RT targets with the LabVIEW Real Time Module. You can use the DataSocket VI and functions to read or write shared variables from other platforms.
Note The LabVIEW Datalogging and Supervisory Control Module supports this property in the Run-Time Engine.
