An event structure can freeze the front panel even if not executed?

[Snamprogetti]

See example (LV9). Two Event structures, each in a case of a Case structure; if they handle the same event, when it fires the front panel freezes.

can you save it as a 8.6 so I can open it?

[Darin.K]

I suggest you read the caveats of using the Event structure in the LV help.  The case structure does not stop execution of the event structure so you effectively have two event structures in the same loop.

As Darin already stated, this is expected behavior and a wellknown DO NOT for event structures.

So please make it a rule of thumb:

Never ever configure two different event structures to fire on the same eventsources!

hope this helps,

Norbert

Good to know. It's not written in the Caveats page

[Dennis_Knutson]

Yes it is. It's called 'Avoid placing two Event Structures in one loop.'

[Snamprogetti]

I know, but it talks about two Event structures executing in parallel (and that's logic).

It does not say they will magically wait for events even if they don't execute...

[Dennis_Knutson]

What you have to understand is that an event structure is always waiting for an event and that placing one inside a case statement does not mean it will not capture events. Two event structures in the while is still two event structures and the case statement does not change that.

I already understood, thanks.

Just saying it's not written in the help, that's it.
