How Do I Control a VI Inside a Subpanel?

[Efrain_G]

 Overview
This example VI show how to control properties of a VI inside a Subpanel

Description
After inserting a VI inside a subpanel, there are ways to actually control what happens on that VI. One of this ways is to use a VI reference to the objects inside the VI in question. This example inserts a VI (that contains a waveformgraph) in the subpanel of a main VI. Then a VI reference is created within the main VI to control the Y scale of the waveformgraph of the VI inserted on its subpanel. In other words, a property of a VI inserted in a subpanel of another VI can be changed. In this case the property is the Y scale of a waveformgraph.

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Run the program "control VI inside Subpanel LV_2012_NI_Verified.vi"
2. Change value of Graph Y Scale Maximum Control and see results

Additional Notes

Make sure that subVi.vi is NOT open when you run subpanelobjref.vi. You will get an error if it is open.
