Add output or input to SubVi

[CasonSwRI]

I need to add an input to a subvi. Is this possible?

[Will.D]

Quite possible.

Go to the front panel, and right click on the VI icon (top right hand corner) and then click "edit connector".  LabVIEW automatically assigns the number of "boxes" in the connecter to the total number of controls/indicators on your front panel.  Indicators are considered outputs, while controls are considered inputs.  To wire a control as an input, click on one of the empty boxes in your connector, then click on the control you want to associate with that box, and the box should fill in whatever colour the control is (pink for string, etc.).  LabVIEW recommends adding more connector terminals than you need in case of future changes...

Search the help on this...it explains it quite well.  Search for "Connector Pane"...it should bring up a lot of info for you.

Thanks. I couldn't find that in the help files anywhere. You rock man.

It's under "connector panes", subcategory "assigning terminals".

Perhaps this screenshot might help you.

When I right-click the icon, I don't get a "show connector" option.  Only "edit icon," "VI properties" and "Find all instances."

I'm using labview 8.5.  What am I missing?

[gdecker]

Never mind.  I was right clicking in the block diagram window, not the front panel window.

Sorry.

On the front panel, click on the terminal you want to assign a control to... then go click on the control you want to assign to that terminal

also ensure that the VI is unlocked or you wont even be able to see the option to do this. It's somethign like Some Toolbar Menu->Preferences->Protection->Unlock

But what if the input is not in the front panel of the subVI ? I want to connect a wire from the VI as input in the subVI.
