Identical VIs for different processes

[rafreitas]

Hi everybody!

I have a project to monitor three identical processes (i.ex., A, B and C) which have the same VI.
To run this project I created three identical VIs and I placed its respective controls.
I'll increase this project in the future repeating the same process (D,E, F and G) but I wouldn't like to need to recreate 4 new VIs.

Is there any way to use just only one VI and just change the controls?

Thank you very much!!

If I understand you write, you need to create clones of a single VI to have multiple running at once.

Check these links for dynamically cloning VIs from a VI template (vit) file.

The last one also deals with subpanels which may be of use to you as well.

What exactly do you mean by "change the controls"?  Can you more details about what exactly is different between these VIs?  If done correctly, you could probably just create a single VI and set the reentrancy to preallocate for each instance.

Hello, Wire_Warrior!

Thank you for the quick answer.

I have a HMI that has a Main VI with 3 buttons (process A, process B and process C). Each button call the process (process_A.vi, i.ex.) one at a time.

Each process VI has many controls like numeric controls, numeric indicators, gauges, and inputs and outputs of my cRIO.

What I'd like to do is build a VI where each process button loading its respective controls.

Is that possible?

Thank you again!
