You might want to use a SubPanel (in the Containers palette). If you have not used them before, drop one on a new VI, then go to the diagram. You will find an invoke node there (don't bother looking for the SubPanel Terminal itself, you won't find it and you don't need to go looking yet.**

Pop up on the Invoke node and select "Help for Insert VI" which will get you to the help page. Study that a bit then go to the bottom of the help page and open the second example: "Simple Subpanel.vi" and run. You might be able to modify this just fine for your application. Or proceed to the other examples there or go the the Help>>FindExamples menu in LabVIEW and search for subpanel.

Good luck!

thanks for reply

but i need shared variable btween VI

how make it ?

I can't answer, I don't use any variables in my VIs. I think it's the wrong way to exchange data between VIs in LV.

And by using queues or notifiers you have a realy important feature: it's triggering of tasks.
