I am looking for a Allen Bradley PLC solution to an automated conveyor assembly line problem.
There are two sensors on the conveyor the first checks that the components have been assembled correctly, the second further down the conveyor detects and either accepts or rejects the assembly based on the information received from
the first sensor. My problem is, there may be three/four assemblies between the first and second
sensors. I need to make sure that the assemblies which are rejected are the ones, which were detected as incomplete by the first sensor. Can somebody help me to find a way of keeping track of them?
