force stop while loop

[MaxXx]

Hello,

I am trying to write a VI that do some operation within a while loop. I have replaced the operation with some simple math operation in the attached VI picture. For the loop in the picture, I just want to add 1 every 15sec. until it reaches 10 and stops. However, I also want to be able to force stop the while loop without waiting the whole 15sec till the next iteration. Is there a way to break the wait time for the while loop? Thanks for the help!

No.

If you want to stop your while loop earlier, you need to use a much shorter wait in there.  Only do what you want whenever the 15 seconds has passed, perhaps by using the Elapsed Time Express VI.

As RavensFan suggested, break your 15 seconds wait into smaller values. Here is a quick example.

Use an event structure with a 15000ms timeount and an event for the stop button. Pressing stop will immediately break the timeout.

Here's what I had in mind (LV 8.5).

When I saw the image I didn't understand. The wire to the sandclock is hidden I have corrected. 🙂

Thanks, the wire must have slipped under there unnoticed when I resized things for the final save.
