Start to measure with a simulate signal

[todoesposible]

Hello,

I want to start to mesaure a signal acquired when the signal that i simulate cross zero. For this, I implement the function zero crossing of Labview, but  it don't detect me the zero crossing of my simulate.

Why?
Is there another possibility?

Thank you very much.

Show your implementation.

This is one piece of my vi.

I make an easy vi, and when i put the button the zero crossing don't detect nothing, only if i push the button again and again. I want that the signal run always, although i have pushed a button.

Hi todoesposible,

it seems that you use Event Structure. So it means that you will perform measurement only when an event occurs = button is pressed.

Your code needs to be refactored and it is not organized and effecient.
You should avoid using LOCAL VARIABLES. The code that you have shared has RACE CONDITIONS. I know that, I'm not giving any answer to the question that you've posted but the information I'm providing here is worth knowing.
