SubVIs from scratch

SubVIs from scratch

SubVIs from scratch


I'm new to LabView (5 days now), and I have some questions to clear out that I couldan't find in examples and neither in the help.

I would like to know how do I add Inputs and Outputs to a SubVI I'm creating from a blank template? I know that if I create from a selection in another VI it will automatically create them but there has to be a way of creating them myself manually.
Suppose that I have a SubVI already with inputs and outputs and I want to add a new output. I don't want to copy the hole thing to another VI, edit it, select it, and create a SubVI from selection again. Also beacuse I have to reconfigure the new SubVI created. There must be an easier way!

Thanks in advance!

RE: SubVIs from scratch

1. On the front panel, right click on the Icon in the upper right, select 'Show connector'
2. Right click on the connector box, select 'Patterns', and choose a connector pattern. It is good practice to choose one for all your vi's and stick with it (I prefer the 4/2/2/4 personally). Also try to keep inputs on the left and outputs on the right half.
3. Now hover mouse over connector pane, cursor will turn to the wiring tool. Click on a connector terminal, it will turn black. Next click on a control or indicator on the front panel you want the terminal to represent.

Wheels within wheels / In a spiral array
A pattern so grand / And complex
Time after time / We lose sight of the way
Our causes can't see / Their effects.

Thanks for your help. I knew there had to be an easy and practical way to do this.
