I thought about what you tell me with event structure : never to use event in event.
But how to do when you use a vi containing event structure  ex  :

You don't give enough information and you image does not tell me anything. I cannot tell what you mean.

For example if you call a dialog style subVIs containing their own event structure, that's probably fine becaue the main VI will wait anyway.

A better rule is to make sure that all event structures are always ready to trigger within a very short time frame and they should not hold up the dataflow, i.e. complete quickly. If you place events inside events, the outer event is deadlocked because it cannot fire until the inner ever fires. If you place loops inside events, the event does not complete in a short time, also not good.

Last question : is there a limit to number of parallele event structure

Everything in a computer is limited in some way, because you don't have an infinite address space, but I doubt you'll ever run into any practical limits. 😉

Hello,

The code behaves that i expected, but one thing i don't know how to solve:

the code in seq, timeout event can takes from 200 to 400 ms, so my 1s (theoric ) sampling rate  is  not constant ,
i can use a mean timeout  to minimize error (700 ms) but  it isn't  very fair.

How can i proceed ?

Best regards

You could just meaure the actual code timing and adjust the timeout for the remaining time balance. See attached.

thanks my lord you are killing me,  an the coerse function what a refinement

me again ...

During sequence loop (1000ms) i would like to have a parallele loop  triggered and acting every 250ms

For  the moment she triggs on seq button, perhaps it sould be better if activated by 1000ms loop ?

The parellele loop is launched but running by itself and i don't now how to synchronise my with 1000ms loop

I         I        I
1234 1234 1234

I tried wait until but without result...


Best regards

Look into Timed Loops.  They should give you the ability to synchronize.

Also look at either notifiers or Rendezvous,  they give the ability to send signals from one loop to another.

Here's one simple possibility:

Note: Of course the tone of the inner loop can be a single constant. I left it as an array to allow for four different tones for 1, 2, 3, and 4.

Thank you

it works great
