Pass data to SubVI state machine

[pallen]

Greetings,

I'm having trouble passing data to a State Machine that I've made into a SubVI.

I know there's something very important I'm missing here.  But I don't know what it is.

I need to be able to pass Start and Stop booleans to this SubVI.  But once the SubVI starts, I am unable to pass any data at all to it.  

I've tried making the VI reentrant.  But that didn't help.  


I know there's a way to do this.....I'm just having a hard time finding it.

Can anyone point me in the right direction?

Queues are the usual way of passing data between independent loops.

The only "data" I'm actually passing are boolean values. 

Is a Queue still the way to go?

...and if you're looking for the easiest way, you could just use a Global Variable to pass the loop stop condition between the VIs.

Are your problem solved?

Have you considered calling the SubVI by reference and setting the Wait Until Done property to false?
