Control of two simultaneously running loops

[rileks]

Hello,

My measurement requires two running instances, each runs in its own while loop embedded in an event structure (used to trigger the action).

In my particular case, I trigger one process in the while_loop1, this should trigger loop2 (initiates my detector and keeps it open until loop1 is ready).

The simplified problem is illustrated in the attached image; I can´t trigger loop2 from within loop1, although switch 2 is activated using the local variable. I essentially do not get the message2 if triggered in loop1. Any idea how to do this??

Many thanks in advance,

Steffen

Writing to a local variable does not fire an event. This has been discussed countless times. Write to the Value (Signaling) property. Use a single event structure with multiple events and add an event for the stop button.

Thanks a lot for the info!! Works fine now...
