two while loops working in parallel at the same time

[luz]

Hello, how can I run a .vi with two while loops working in parallel at the same time? . I want that when I run a vi both can be activated o desactivate, but I can't get it. What can I do?

Thanks a lot.

It may be not exactly what you want but it will work.  You can not deactivae a loop so see attached code.  Should work for most applications.

I have a similar problem before. I also used a local variable to stop another loop. It didn't work. Now I understand the key is that we must use "switch" instead "latch" for that stop button.

I can't get it. I want to do an adquisitiong or another thing. I send you an example of I want to do. If I do the program step by step I notice that there is an error 200279 in the adquisition, what means that there isn't sincronization. Can you help me, please?

Thanks.

Put Delay of 100ms in both while loops, it will help in balancing execution of both while loops. Or use State machine pattern to do more tasks in Single While loop.

Hope this would help.

What is state machine pattern?

Here are some links for state machines.
