invoke node

[ddannel]

Ciao a tutti, sono un principiante con LabView.

Voglio fare un'interfaccia che contenga una parte ripetuta piu' volte: penso si debba usa invoke node; ho iniziato con un semplice esempio.

Base.vi: contiene un integer input and un integer output collegati tra di loro. Questi due widjet devo essere visibili sull'interfaccia principale

Top.vi: usa Load.vi per generare il reference of Base.vi

Run.vi: passa i parametri a Base.vi

Nell'esempio che allego, per semplicita', ho inserito solo un'instanza di Base.vi...ma anche cosi' non funziona

Hello,

I'm sorry I don't understand italian... Could you try to ask your question in english ?
Or maybe you should repost your question here, on the italian community

Hi All, I'm beginner using Labview.

I want an UI thant contains more istances of a single part: I think I have to use a "invoke node"; I started with a simple example.

Base.vi: it contains un integer input and an integer output likend one to the other. These two widjets are visible in the main UI.

Top.vi: it's the main UI; it uses Load.vi to generate the reference of Base.vi

Run.vi: it gives the parameters to Base.vi

In the example in attachment, in a simple way, I inserted only one istance of Base.vi...but it does not work.

Hello,

I am not sure if this is exactly what you want but I think it works. Let me know if it's ok for you.

I changed the settings of Base.vi, if it is set as reentrant, the subpanel won't work because there will be 2 instances of the vi in the memory.

I hope this will help you 😉

thank for your help TiTou....but... you did not find the problem.

If I modifie the input of the Top.vi (outside the SubPanel) I would like see the same value in the output (outside the Subpanel); because the Basei.vi

is a cc between the input and the output; so at each time all widjects should have the same value.

[TiTou]

Is it not what is happenning ??? When I change the value of "input" outside of the subpanel, a short time after, the 3 other controls get the same value. Is it not what you want ?

[ddannel]

Yes, sorry, IT'S PERFECT. Maybe I did an error in starting the Top.vi.

Thank you a lot.

You're welcome !

by the way, I am french
I am not really a football (I mean soccer) fan but I hope we'll have a nice final this sunday, may the best team win 😉

I used your architecture with my project, and it works well.

               But:

If a want add a new Sub panels with a Base.wi,

this message is showed:

LabVIEW:  Cannot open VI because it is already in a subpanel control.

In attachment there are 2 examples:

1) Top.vi: it works weel (1 sub Panel)

2) Top2.vi does not work (2 sun Panels)

Thank you for your help.
