Even simple bit logic operations can be beneficial in more advanced PLC programs and SCADA system programming. Ladder logic is mainly for bit logic operations, although it is possible to scale a PLC analog input. Ladder logic is made out of rungs of logic, forming what looks like a ladder – hence the name ‘Ladder Logic’. It is a graphical PLC programming language which expresses logic operations with symbolic notation. Ladder logic (also known as ladder diagram or LD) is a programming language used to program a PLC ( Programmable Logic Controller ).

Ladder Logic Programming with Instructions.GO TO PART 2 OF LADDER LOGIC TUTORIAL -> Ladder Logic PLC Programming Tutorial If you want to deepen your understanding further, you can also take an online PLC programming courses. You will be able to start making real PLC programs with ladder logic in almost any PLC programming software.Īfter reading this tutorial I strongly recommend that you continue with part 2 of the course. In this ladder logic tutorial, you will learn everything you need to know about the ladder diagram PLC programming language. So if you already know a little bit about relay control and electrical circuits, you can learn ladder logic even faster.īut that’s definitely not a requirement, and I myself didn’t understand relays when I first learned ladder logic. The smart thing about ladder logic is that it looks very similar to electrical relay circuits. The great thing about ladder logic is that it’s much more visual than most programming languages, so people often find it a lot easier to learn. One of the best visual programming languages is a PLC programming language called ladder logic or ladder diagram (LD).
