Open different RTs

[electronic_lab]

Hello,

I have a program of a test bench where I open different VIs on windows depending on the reference I want to test. For the moment I only have one, so I open an only RT and Windows-RT are communicating each other. Now I want to make a menu on RT and depending what reference I want it will open a different RT VI. Does it work the same as in Windows? Or how its made?

You can "open" (aka "call") different subVIs in a RT target: simply create a MainVI, that calls subVIs based on a command/parameter sent by your host application!

• I guess you talk about realtime targets (like cRIO)!?
• How do you open "different VIs depending on reference"? Which "reference"?

Thank you. I mean, If in the menu of Windows I select the button A, it will open in RT the VI A, if B, the VI B.... In windows I make it with events, I guess in RT can be done also like that. Yes, I talk about Crio.

So your host application (on Windows) sends a message to your RT target with the command to execute VI "x".

The RT application receives the message and uses the command to select one of several cases of a case structure to call the requested subVI.

This will be a very simple solution…
