Hello everyone
 

I have products with different references such as A1, A2, A3, etc. I scan these references using a Zebra scanner.

 

I would like to create a counter that ignores any reference that has already been scanned.

 

Does anyone have an idea, please?

We cannot debug picture. Overlapping wires and structures, not indication what you mean by "references", local variables where we have no idea where the terminal is. A feedback node that makes no sense, etc.

 

Pleas attach your VI, give some reasonable inputs. typically placing items in a "set" would be easiest to tell if an item already exists.
