Conveyor Data Handling - PLC Programming Cookbook

We often want to track part data as those parts flow through a conveyor system. This video shows how to do that in a PLC with ladder logic, and a bonus operator station with buttons and lights.

How about the duration of the one shot, isn't it safer to keep the one shot duration short enough in order for the normally closed contact of the one shot to be true for latch to keep the light on ?

I'm not sure what you mean. A one shot, by definition, stays on for one scan of the program. Ever part of the program will see the bit high exactly once before it goes low again. If you're talking about the pushbutton one shots (ie PassPB_OS), only one branch of the rung is active at a time, depending on the state of the one shot. That's how we want it to work.
