stopwatch

[umaira]

I need your help regarding my program in the labview. I already insert the stopwatch. Recently the program can run and the stopwatch need to click the start button manually. The stopwatch does not run simultaneously with the program.  Now, i have problem on how to link the program to the stopwatch. I want the stopwatch start simultaneously once I start run the whole program.

Hi umaira,

your "converter" subVI is missing. I guess that's the part you call "stopwatch"…

The stopwatch does not run simultaneously with the program

Well, as long as you use that button to start your watch you need to click that button.

But what would happen once you use a different condition to start your stopwatch?

You need to view the Introductory Material for LabVIEW.  You have three loops running in parallel (though you might think they run in the order you've written them on the screen).  There are multiple Start and Stop buttons, the loops are largely uncontrolled (the third loop, for example, writes three images over and over again at a commanded rate of 1KHz to the same three files!).

I'm guessing that your starting material might be from NI, as I see numerous Express VIs and Dynamic Data wires -- these are useful to get people who are not interested in learning LabVIEW to throw something together quickly that does something simple.  But it really is irresponsible to give you even these blunt tools without mentioning Data Flow.

Here is a link, at the bottom of which are tutorial material you should view.
