Using radio button to control while loop in subvi

[User002]

I have a radio button in a while loop in a subvi and I would like to control it using the main vi.

I have looked at:

My radio button has two states, On and Off, which are indicated by a round led for each. I am having difficult comparing the value of the radio buttons property node to the state that I want. For example I want the while loop to end if Radio Button value is On. I tried using variant to data, but I either did it wrong, or that is not what I am supposed to do.

do you mean this vi

Sort of except this is what it would look like to control it from the subvi. I want to be able to control it from the main vi.

so you need this

So it will not work without making it an event?

No I dont think so

No you don't have to use an Event Structure to perform this task in the Subvi.

See the attached example.

If you get the "Radio Buttons" reference from the Subvi, you can directly control it from your Main vi.
