run a for loop for specified time period

[sukanya]

Hi

I want to execute a for loop for a certain specified duration which keeps changing.I want to specify the duration for each run and I want a for loop to be excuted for the same.So how do I  interface a timer to the for loop's loop count?

Thanks,
Sukanya

Do you want to run the loop for a variable amount of time or for a variable number of iterations?

I'm not too sure.This is what I need.I have a VI that captures videos and saves it as a .avi file.Now I need to add another label to the display through which I can specify how long ( in seconds) the video should be captured.I initially had the VI writen using a while loop.I changed it to a for loop so that I can add this parameter.But I'm kind of confused now as to how to proceed.

Thanks,
Sukanya

Sounds like you would want to run a Loop( at a preset iteration rate) for specified number of seconds. Is that correct?

you can use Timed loop for the said purpose it will work fine as i think

Yes,that's precisely what I want to do.

Look at attached VI

This link will teach you how to configure a timed while loop

Hope this helps
