Timer in a while loop

[CYTeoh]

Dear experts,

I would like to stop the while loop and save the data after 5 sec. How do I connect a timer switch to "loop condition" (red dot in while loop) so that VI will stop after 5 sec of recording?

Thank you.

You can't. What made you think you could do something like that? Use the Elapsed Timer VI to tell you how much time has elapsed. You can reset it for the next trigger.

Dear smercurio_fc,

My application is need to turn off the VI automatically after 5 sec in a while loop. Could you suggest a way to do this?

Your help is much appreciated.

Thank you so much.

Pay attention. You were told you can use the Elapsed Time function. Look at it. Make sure Context Help is turned on.

Dear Dennis_Knutson,

Sorry, I am new to Labview..

I get what smercurio_fc mean. However, as my understanding, Elapsed Time function VI only able to show me the elapsed time and reset it after the time target. It is unable to stop the VI automatically at exactly 5 sec. I have to stop it manually by clicking on the STOP button. By this way, I can't stop the VI at exactly 5 sec...

Thanks for the help.

Your understanding is completely wrong. You certainly did not turn on context help like I said or if you did, you did not read the help details. Nor did you pay any attention to the various outputs of the function. There is a Boolean output. Look at it! Then think about all of those dedicated people at NI that spent so much time writing the help file. Then think about all of those people that post questions who think that's easier than finding the answer themselves.
