You can build ladder logic PLC programs and simulate them for free. This guide will show you how to download and install the popular RSLogix Micro Starter Lite and how to use the RSLogix Emulate 500 to simulate your ladder logic PLC programs.
Do you also struggle reading your own and others huge ladder diagrams?
The truth is, that even though ladder diagram (LD) is an easy programming language for beginners, it can be very hard to read and understand. That’s why Structured Text is a better PLC programming language, and you can learn it in this tutorial.
You probably have heard about the Siemens S7-1200 PLC. It is the latest Siemens PLC and the best for learning. Get the Starter Kit with the programming software SIMATIC S7 TIA Portal and begin learning Siemens PLC programming. You can even control the S7-1200 PLC with your smart phone!
You may know the difference between normally open and normally closed contacts, but do you know where to use them? This article will teach you where to use normally open and where to use normally closed for inputs and in your PLC program. You will learn how to connect your PLC program with the physical PLC inputs.
Ladder logic symbols are the basic building blocks for ladder diagrams. Right here you will find all the ladder diagram symbols which are described in IEC 61131-3. The symbols are available for download in all formats and in a PDF-file.
I will start this article by making a confession:
When I develop a PLC program, I steal other people’s ladder logic.
I am stealing ladder logic examples for inspiration and solutions to my PLC programs.
From time to time you will be facing the same problem, when you do PLC programming with ladder logic. By looking at examples of ladder logic programs, you will be able to find a solution to your problem very fast. You may even find a smarter solution in the ladder logic examples than your own solution.
