what ´s way of using this loop tunnel ?

[jaga1984]

I was wondering what is the purpose of this  loop tunnel

and this unwired loop tunnel in the program.

I need to know because I´m adding some basic features to this labview program.

Thanks in advance.

The first one can be used as a way to determine execution flow as the While loop must finish before the For loop start, although it'd be better to wire an error wire to the for loop, or move '1' inside the while loop instead.

The 2nd one has no function.

From the picture i'd say keep the function 'Anal Enter' and start over with the rest. 😄

The upper one forces the for loop to run after the while loop by data flow.  The data need not be used but the connection forces the order of execution.  Of course there may be other connections not shown in your image.

Given the state of the code it is quite possible the 'a' is wired to something in the second loop and the wire is "hidden". I agree with the early statement that this is a prime example of code in need of a re-write. I can't imagine how bad the entire block diagram would be.

Silly, but fun. 😄

I'd recommend not trying to re-write this program unless it doesn't work or you have a really compelling reason.

Well i agree, rewriting is often costly, but some cleaning up and modularizing is quite helpful for future modifications.
