stop for loop

[etay23]

Hi,

I'm using for loop for let's say i=40

can i stop the loop in the middle (when i=20) and contino the program from there?

Regards,

Etay

Its not possible to do that in LabVIEW

The FOR loop has to finish its set number of iterations before stopping

You must use a while loop if the loop must be stopped before its set number of iterations !

For now that is.  to answer your question, you can put the 'meat' of your code within a case structure, and 'skip' it if you have an undesireable condition.  Or you can create a while loop with multiple exit scenerios including your undesireable condition(s) or completion of processing your data structures.  The choice is yours.

In this case the loop can be stopped before the loop count

If the loop count is 20 and the array size is 10 then the loop will iterate for 10 times only

If the loop count is 10 and the array size is 20 then also the loop will iterate for 10 times only

So which ever is less the loop will iterate that many times

Hi Kumar,

Can you attach the screenshot once again ?

On Parthabe's request reattaching the image

In this case the loop can be stopped before the loop count

If the loop count is 20 and the array size is 10 then the loop will iterate for 10 times only

If the loop count is 10 and the array size is 20 then also the loop will iterate for 10 times only

So which ever is less the loop will iterate that many times

Still not able to catch the image.???????? i can mail you if you could post your mail id

You can also program the logic into it. I've used this a few times. Just put everything in the loop inside a case structure, then you can do some boolean operation that you want to use to stop the loop, wire this to a shift register and use it on the next iteration. In the true case, just wire everything through so nothing happens once the condition is met. The loop is still running, but it isn't doing anything and will finish very quickly.

I also added a shift register for the iterator in this example so you could obtain it after the "break" condition occurred.
