Configuring a VI Reference Constant

You can configure a VI Reference Constant in the following ways:
  • Drag a VI from the Project Files tree onto VI Reference Constant.
  • Drag a subVI call from the diagram onto VI Reference Constant.
  • Drag a VI from the palette onto VI Reference Constant.

After configuring a VI Reference Constant, its output VI reference type is a strictly typed VI reference. You can reconfigure VI Reference Constant with another VI if necessary.
