Event Structure

[S.Neo]

Hi,

I am learning how to use an event structure with state machine. The state machine is able to go from state to state when the "wifi module" boolean is pressed. However the program hangs after I press the "stop" button when the "wifi module" boolean is executing. May I know how to stop the program when the wifi module is executing?

A couple major problems.

1.  Your event structure isn't in a while loop.  So it will only execute one time.

2.  Your events are set to lock the front panel until the event case is complete.  So if it can't execute a second time because there is no while loop, the next event that gets triggered will lock the front panel, and the event case will never complete because it is no longer in the path of execution.

Hi, 

What does it mean by "lock the front panel" ?

I have added a while loop to the event strucuture. How do I let the program continue to flow even if there is no event?

Right click on an event and pick Edit Events handle by this case.  Then look at the checkboxes at the lower middle of the dialog box.  Be sure to click on help.

How did you expect it to continue before?

Looking at your state machine in the lower half, I don't understand the logic you have in there.  It is very odd how you have the multiple embedded case structures.  But the code doesn't seem to really do anything and looks more like a proof of concept.  So I'm not going to spend time trying to decode that logic.
