Use time in True/False condition

[Loukask]

Hello to everyone, 

does labview somehow give the option to use time in a condition? I will give an example to make it clear. x=10, y=5 (and increasing and decreasing until after sometime reaches y=10). I want to have a True signal when x=y for more than 3 sec. 

Can this be done?

Sure.  Use the Elapsed Time Express VI.

Wire a False to the Auto-reset.

Whenever X <> Y, then feed a True into the Reset.  When X=Y it is false.

Now when X=Y for more than 3 seconds, the output becomes true.
