multiple subsequent loops

[shayelk]

Hi all!

I'm building a VI which will run a number of subsequent tests. each test runs in turn inside a while loop until a certain condition is met, but I also want to be able to kill the operation with a single stop button at any time.

Currently I'm using a notifier and an additional loop for the stop button, but that method adds a lot of wiring to the VI, and makes it complicated to make separated subVI's from the tests.

Is there a cleaner way of doing what I'm trying to do?

a simplified version of the code is attached (instead of actually testing stuff I just made each loop count 10 iterations for the examples sake)

Thanks!

Hi shayelk,

but that method adds a lot of wiring to the VI, and makes it complicated to make separated subVI's from the tests.

Once you use NAMED notifiers you can easily create separate subVIs…

- Less wiring: use a global variable…

- Less wiring: use a FGV aka AE to hold your STOP condition…

Thanks! I'll try it out...
One question though- what would be the best way to go about making the loops run one after the other? (as I know sequence structures are not recommended)

You could create a data dependency by passing the error cluster along from one loop to the next.

This is really the wrong architecture, overall highly flawed and overly complicated.

Just use a single loop and a state machine architecture and everything will fall in place.

Rethink the code from the ground up!
