Want to start 2 state machines running parallel. Have been suggested to use UserEvents
I have 2 questions:
1)
Am I right when is say that I can place my state machine in the subvi instead of the random generator and the waveform chart?
Yes, one way if you create your state machine by using a shift register (with Enum or string) located on the While loop around the Event structure. Note that, the timeout of the Event structure which is creating the random numbers at certain intervals. You could have your DAQ here. Of course, there are other options, like using two parallel loops in the subVI, top loop only for the GUI and Dynamic Events, and the bottom loop would do the DAQ, and even hold the state machine logic...
2)
how to start subvi with arguments?
Also have a look how I did in my example project: I call the subVI with two arguments: an ID (numeric U32) and the typdef cluster holding the UserEvents references. You can just easily create another input terminal for this subVI, like a cluster which could hold several parameters (like DAQ parameters, COM ports, device ID, etc...). After modifying this subVI, do not forget to update the "Type specifier VI refnum (for type only)". You can right click on this object, and browse your modified subVI, so the new input terminal will "appear" on the "Start async call" icon.
EDIT: start to design your state machine in the subVI, and later post your VI so we can comment and help if you need.
