How to update DQMH status outside of main?

[Arvin618]

After learnling DQMH, I have 2 Confuses:

1. Why the main vi in application lib is different with the main vi in modules?

2. I have a application which have a camera and a line stage.

2.1. Click start

2.2. Then the stage move to Position 1, after(or Wait) the stage arrived Position 1, Camera take a picture.

2.3. Then the stage move to Position 2, after(or Wait) the stage arrived Position 2, Camera take another picture.

...

2.4. After finish taking picture, stage go back to the homo position.

After learning DQMH, I know how to create the camera and line stage modules. But for the main function, how can I use DQMH to control the sequence?

Thank you very much

We wanted to show that the calling code did not need to be a DQMH module as well. You can see that the Application Main.vi is a state machine. If you take a look at the shipping examples, you will see that they are simple VIs that are calling a chain of DQMH Requests, in those, we don't even have an event structure.

That said, our internal projects tend to use a DQMH Module for the top level application as well.
