You can use the Variable Reference property with the Variable properties to configure shared variables programmatically.

Note  Shared variables can only be created, configured and hosted on Windows systems. You can use the DataSocket VIs and functions to read or write shared variables from other platforms. If you have a VI with a Shared Variable node that was configured on a Windows system, you can also move that VI to another platform.

Complete the following steps to configure a shared variable programmatically.

1. Use the Class Browser window to select the Variable Reference property and place it on the block diagram.
2. Place a Property Node on the block diagram.
   
   
3. Wire the Variable Reference output of the Variable Reference property to the reference input of the Property Node.
4. Right-click the Property output of the Variable property and select Create»Property for Variable Class and a property from the shortcut menu. LabVIEW creates a Property Node for the property you selected.
5. Configure the Variable properties as needed.

Note  Changes you make using the Variable properties take effect after you save the project library.
