Change Property of Main VI Control through a Sub VI

[SDuffyLV]

Hi All,

I'm trying to do a relatively simple task of causing a control to blink if it is outside of the set limits (0-400). However, I have multiple instances where this occurs so would like to control the blinking through a Sub VI.

Attached is my attempt at this. It should provide a better picture of what I'm aiming to do.

Create references for each FP object you might want to blink.  Cast them to generic controls (the highest ancestor class that has a "Blinking" property. ) Pass the selected  reference to the subvi .

Note, you should also be able to pass a reference to the main vi and set blink.speed and blink.color. double check that though,  those may not be runtime writable since they are generally set at new vi creation and apply to the vi not each control.
