Call VI with statechart

[Vincent90]

Hi all,

I have an application wich command a 3D helicopter.

I want to developp a statechart application which test engine, then test encoder and finnaly lauch the VI which command the helicopter.

How can i call a VI with a state of the statechart?

Does a statechart can be used in RT applications ?

Yes, Statechard can be used in RT.

Inside of a state (after you double-click on it) you will have a block diagram.  The functions pallete will be available to you so you can click Select a VI and find the VI you want to add.

Tank you for your support PackerFan,

1) I want to run two parallel execution but i didn't manage to do it. There is a tool call "Fourche" but i can't use it.

2) Is there a way to test my application which necessit a cRIO (FPGA Soft) without my application nearby me. A way to simulate the FPGA target and the cRIO ?

Regarding other statechart soft, i found LV statechart really hard to get used to it.

BR,

Two Statecharts in parallel, or two states in parallel.

If it's two states, they need to both be in a larger state.  Check out the screenshot of the diagram I attached (sorry, the browser I'm using right now won't allow me to place it in the post).

I don't know of any way to simulate the cRIO without having it there.

Thanks PackersFan,

Is there a way to enable or disable a VI in a state ?

For instance, in the first state I enable VI 1

when first state executes the VI 1 opens and runs. If I don't exit it by myself, is there a way to switch off the VI 1 in state 2 ?

BR,

Vincent

It's just LabVIEW programming, so things like case structures and controlling VIs by reference are all available to you.
