Plug and play instrument driver example program

Hi,

 

I am very new to labVIEW and I am trying to integrate my Aalborg mass flow controller in the labview environment. Aalborg already has labview drivers with example projects, which I have installed. I am using one of the example projects and the issue I am currently facing is how to acquire the recorded data. In the block diagram, the example project is just one block and I am unable to expand to connect a 'write to measurement' block.  I will appreciate some guidance.

Hi aj,

 

important reminder: we cannot debug/run/edit iamges with LabVIEW!

So to be able to help you you should attach real code to your messages…

Open the example VI and edit its conpane ("connector pane") to output the readings…

Thanks for the response, Gerd. The issue is I am not sure how to open the example vi. Double clicking it just opens up the front panel for visualization. Whereas in the block diagram window, it’s just a single block with no insight as to what’s happening within.

Hi aj,

That's standard behaviour: double-clicking a subVI icon opens its frontpanel.

Btw. ctrl-clicking opens the block diagram window, too…

Please attach that example VI!

When I open the VI you attached in your last message then there is a lot on the block diagram!

And there even is a lot of text in the VI documentation, which you could read in the context help!

 

Maybe you should start with some basic LabVIEW tutorials, they are offered in the header of the LabVIEW board…

Best regards,
GerdW

Sure, thanks. I've been able to open the vi block diagram now.
