    Last Modified: January 12, 2018

    Represents a VI reference on the diagram.

    Programming Patterns

    Use this reference constant to specify a type for the type specifier VI reference input of Open VI Reference. Only its type matters to Open VI Reference.


    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.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
