AC500 Counting parts
This is the first draft, which shows basically two sensors on infeed and outfeed. These sensors are connected AC500 high speed counters. Looking for solutions if we can still be able to track the rejected without the sensors. Hope it gives you an idea on what i am trying to accomplish.
I highly appreciate for your comments.
Very good for the scheme, it is now clearer. What frequency are you currently counting on in the machine? So how many pieces come in for a minute?
Why you have decided to use fast counter in your logic?
In any case, I do not know if you've already tried to make the algebraic difference between the input counts and the output pieces with the SUB operation, using the input count (word format) and output pieces counts (word format) as operands. The difference is of course the number of reject. But is really too simple, I'm not convinced that you have not already tried it
The system precision depends on the really speed of pieces in input and output, do you have one tolerance about the real, acceptable number of rejects?
