Need Help detecting value change.

[RaviPaike]

Hi All,

I am creating a VI which will output 1 when the previous value of a numeric input is different from the current value. I am comparing those two values using the 1 sec delay. But I am having problem only for the First iteration when the Initial value of the input is not equal to 0. because the bydefault the delay block sends 0 value for the first iteration. I tried lot of things but couldn't find way arround it can somebody help me in this.

Thanks in advance

[Hi Rave:

Try this:

attachmentid=1011]

also, check out Functions>Advanced>Synchronization>First Call? of use in different, but somewhat similar situations.

Hope this helps.

Best Regards, Louis

Data Changed is in the OpenG comparison pallette. You do use OpenG, don't you?

Hey Thanks Guys. :worship:

Todd,

I was a OpenG user but few days ago due to some problems I have formated my PC so I lost all my data. Now I have downloaded the OpenG again.

Thanks for the Help
