How do I display subvi indicators on main front panel?

[scott-e]

Hi, I have a vi that calls several subvi's in a sequence structure, how do I display the indicators of the subvi on the main calling program's front panel? Any examples? thanks - scottyb

Avoiding globals, you can easily copy the sub vi's indicators and place them on the main front panel. In the subvi's front panel, wire the indicator(s) to the vi's terminals (right click the subvi's icon in the upper right corner and display the terminals - you may have to add additional ones). In the main program's diagram, wire the copied indicators to the output terminals of the subvi.

Another possibilities is use the Datasocket look at the LV example

:Program Files\National Instruments\LabVIEW 6.1\vi.lib\platform\dataskt.llb

If you want the indicators to update while the sub-vi is running (and not after rutting), you can create the indicators in your main program, and then right click on them and create a reference. Pass the reference to the sub-vi, and in the sub-vi you can use property nodes to change the value of the indicator(s) on your main application.

This is good for up to date monitoring but can REALLY back log time critical subvi's, so I would suggest avoiding this if timing is of importance.

Can I display sub Vis on the front panel of main vi such that when I click on any one of the sub vi ,it starts to execute.
Please help me to do this.

Did you look at how old this thread is?

You can display the front panel of a subVI in a subpanel. See the examples. Clicking on a subVI makes no sense. You click on front panel controls such as Booleans. An event structure would come in handy.

I saw a presentation at the CLA Summit last year where someone had made a plugin architecture that showed the flow of data through acquisition / processing / analysis with the icons of the plugin VIs on the front panel.

I think he used the VI->VI Icon.Get as Image Data method to then display the VI icons of the plugins in a 2D Picture control and then use the event structure to pick up on clicks on the icons drawn on the picture control.

It was pretty neat!

A simpler solution would be just to display the VI names in a listbox.
