how to set the input and output of a subVI

[Forrest_Bao]

I am trying to configure a subVI by following Chap. 7 of "LabVIEW fundamentals". But I stuck at "Building the connector pane".

My subvi is quite simple, just for testing purpose. I plan to do a summation and display the result. So I placed one numeric Add icon on the block diagram and a numeric Indicator on the front panel. I built a connector pane with three terminals, two for input and one for output. 

But, how could I associate the terminals on connector pane with inputs and outputs of terminals on the block diagram? I wanna build a subVI, whose input are two numbers and display the summation on the subVI.

Hi Forrest Bao,

open your subvi. Go to the Front Panel. Right click on your icon and select, show connector pane. Click on the place where you want to link your control with. Click on the control/indicator which you want to assign with the selected place. If all is ok, the color will change from white to ... depending on the linkes data type.

ok, so, what if wanna disconnect the association between a terminal on connector pane and a control/indicator?

Hi Forrest Bao,

use the right mouse key as often as you can in LabVIEW. It´s very helpful. If you right click on a link in the connector pane, then you can select to disconnect selected or all.

alright. Thanks. Can you tell me a reference, i.e., documentation or manual, that I can read to know those things you just mentioned?

Hi Forrest Bao,

see the free courses: http://www.ni.com/academic/lv_training/d/how_learn_lv.htm,

the shipped examples in the example finder and

the LabVIEW help.
