First, Happy Thanksgiving!
Earlier today I watched a tour of the Hershey chocolate factory. Near the end, after the chocolate's been made into kisses, the pieces are dropped into several weighing hoppers and some controller chooses from among these which to drop into a bag to arrive at the exact desired weight. My question is, what's the algorithm to do this? Is it something in PLC logic, something purpose made by the hopper builder, what?
Thanks
