using event structure with ADSOCX read

[DabView]

I am new to event structures but I like what I am seeing. I have a loop that grabs a picture from a camera and processes the picture only when a bit is true from Beckhoff Twincat PLC (using ADSOCX to read the memory location) My attempts at using this with an even structure has not proven fruitful. Any help would be appreciated see attached document

You have an event case where Beckhoff Camera Read Input value change.  How is that event being fired?

Beckhoff Camera Read Input is an indicator, so there is no way user interaction can trigger it.  Only by using a Value (Signalling) property node will that event occur, and I don't see that in your code.

(Please don't post screenshots in word documents.  Attach an image as a .png file.  Or better yet, attach the actual VI)

The ADSOCX is reading the memory location of the boolean from Beckhoff's Twincat PLC which is programatically changing the value.  It is not a user event.  I've attached the VI as requested.

From what I am seeing, I think you would benefit a lot more from a State Machine architecture.  You can have a state to look for the input boolean and progress to the read state when true.  If false, just call the same state.
