Learn how How Ladder Logic Works in the PLC. This is key to a beginner’s understanding of PLC Programming. Here is the full ladder logic tutorial: http://www.plcacademy.com/ladder-logic-tutorial/ From my ladder logic tutorial is here an animation of how it all works. It is very important to know how the ladder instructions work according to the PLC scan cycle. All PLC programmers has to know about this. Step-by-step this animation will show you how each input is scanned and stored in the PLC memory (input register). After that, it will show you how the ladder logic is executed in the PLC. Each instruction gives out an RLO (result of logic operation) to the next ladder instruction. At last the animation will show how the PLC sets its outputs. The outputs will be set as a result of the ladder logic.
