Hi, I am new to LabVIEW and have try to use the Boolean Crossing PtByPt Vi as attached but it does not cross into the stage when I trigger the input. Can you advise? Thank you.
Solved! Go to Solution.

Looks like you are trying to capture the event of a boolean changing. Lucky for you there is a structure to help called an event structure.
See what happens when you make a vi like this:

You didn't attach a VI, you attached an image of the VI.
The crossing probably is detected, but your VI runs so fast (without a wait) that you won't be able to tell. The crossing is only true for one iteration, and that will last for <1 ms.
Run the VI with execution highlighting on. Or put a wait in the VI. Or make the loop stop if the condition it true.
Once you get the problem, step up to the suggested event driven solution.
