subvi

hi

Question:

Can i create an empty subvi?

My purpose is when i start a big program from scratch, i start from the big picture. Then, i create several small subsystems, which are obviously empty in the beginning. then, i will fill up those subvis. Then, continue to smaller one. Hence, this hierarchical metho is better.

Yes.

To add a bit to Ravens Fan's answer, you might add Front Panel controls & indicators so you can wire them together and show what data types you plan to use.

I think you can just put a while loop and a stop button for a vi.(with a bit of delay.. else your system performance will be shooted to 100%). later you can think of the controls and indicators....

LabVIEW even has a bunch of vi templates you can use to speed development a bit.  For instance, there's one with error in and error out, already connected to a standard pattern in the expected the locations.
