Connecting Input and Outputs of a VI

[ibzrehmani]

Hello,

I am fairly new to TestStand but I am trying to link, a VI's input with output. So I made an example project and doing the follwing:

First VI:

Takes two numbers and adds them and outputs the result to an indicator

Second VI:

Takes a number and squares it and outputs it 

They look like this

I can do this fairly easily in Labview, I would just link the out of the First VI to the Second VI's input. Can I do this in TestStand?

I only get this far before i got stuck, as demonstrated in the picture below:

Do I have to hit f(x) and link it somehow to the first VI in my main setup? (which look like this):

Apologize in advance if this is really straightforward and I'm missing something obvious!

Any and all help is greatly appreciated.

Cheers!

You could create a local variable in your sequence and then the output of the first VI goes into that variable.  Then, the second VI takes that local variable as an input.

You can use a variable to pass data around TestStand:

1. Right Lick under Locals in the Variables pane
2. Insert Local » Number » (give your variable a name)
3. Write the output of your VI to that variable (either using the f(x) or typing it out):
4. Pass your variable into the next VI.

You'll probably find the Getting Started With TestStand guide useful, chapters 5 and 11 cover variables and VI's.

Hope this helps!
