This is due to the fact that every function you want to implement in your PLC program, there are many different solutions.

Try to design the ladder logic by yourself.īut even though you come to a solution, there might be a smarter way to make that piece of ladder logic. When you look at a ladder logic example it may look different from your ladder logic. The first thing you naturally would do, is to think about it for yourself. Let’s say you have a specific functionality, you want to implement in your ladder logic, a PLC timer function for example. If you are new to ladder logic, check out these short video tutorials to learn about the basic instructions:Īnother reason to make use of ladder logic examples is, that you can learn from them. If you want to learn ladder logic from the beginning, you should check out my ladder logic tutorial or maybe even start learning from an online PLC training course. I wrote another article where I included examples of PLC analog input and output programming. That is why I often make use of PLC program examples. So that you don’t have to invent everything from the very bottom each time you are developing a new PLC program. By doing so, you will shorten the development time of a project. You can “copy and paste” lines of ladder logic symbols from one PLC program to another PLC program.

Reusing code can also have advantages when you’re integrating a SCADA system. In fact reusable code is widely used and many automation projects are build on the ISA-88 or S88 batch control standard which encourages reusable function blocks. You can reuse chunks of a PLC program in your own PLC program. In this case the PLC programming language ladder logic. The reason I use ladder logic examples is one of the big advantages of code. Ladder Logic Examples and PLC Program Examples ⇓. You can skip those and go straight to the PLC program examples: There are several reasons to use examples of PLC ladder logic. You may even find a smarter solution in the ladder logic examples than your own solution. By looking at examples of ladder logic programs, you will be able to find a solution to your problem very fast.

I am stealing ladder logic examples for inspiration and solutions to my PLC programs.įrom time to time you will be facing the same problem, when you do PLC programming with ladder logic. When I develop a PLC program, I steal other people’s ladder logic.

I will start this article by making a confession:
