I have a piece of equipment used for washing product as a group through multiple stages. The machine has one conveyor from start to finish. When the machine runs the conveyor is always 100% full and if there is not enough product to fill the whole conveyor the infeed shuts off. I have a shift register set up to track when the infeed conveyor is allowing product into the washer that shifts based on the mat speed of the washer. In Vision I would like to create a "gap table" of sorts to display when there are empty section moving through the machine. Does anyone have any ideas on how I can accomplish this? I have no issues reprograming the shift register however needed but I cannot find any good way to display in a single bar where product is present and not present and track it through a moving conveyor.
