Events between 2 Event structures & Queues.

[Olivioloyer]

Hi Everyone,

Attached you'll find a example of Two event structures inside while loops.

The bottom loop is paused or release by a queue.

I don't understand why the play event is not registered on the bottom loop the first time it is fired.

any idea?

Thanks a lot,

Best Regards,

I think the problem is how you're using the Dequeue in the bottom loop - it's waiting for a value from the Boolean queue before the event structure has registered for the User Event for the first time - therefore that first event gets lost.

Hi Greg,
Thanks for your answer, I understand that but is there a workaround?
How should I do to make sure I register the first event?
Also, is there a way to check timing on events and queues, for example how can I know that an event has been registered on a register event vi?

Thanks

Thanks You were perfectly right I just inverted the order of execution with the error wire and it works great, 

Thanks
