This e-book provides you with both fundamental and cutting-edge coverage of both hardware and a software aspect of great PLCs that are known as SLC500 and MicroLogix processors manufactured by Allen-Bradley ®. The exercises in this text assume you have not programmed any SLC 500 or MicroLogix PLC using a personal computer and software before. Since this is an introduction to programming a PLC, the text will show you how to program basic ladder diagrams. I have assumed that you have loaded at least a copy of free trial version of LogixPro 500 ® software (which is a general purpose PLC programming software) on your personal computer from internet. The exercises in this text are designed to familiarize you with the operation of LogixPro 500’s simulator and to step you through the process of crating, editing and testing PLC programs utilizing all logic instructions supported by RSLogix 500. In the bibliography section of this text I have provided a link where you can download a free trial version of the LogixPro 500 simulator software that I mentioned earlier to do all your exercises with it. LogixPro 500 software is a great software hence even if you fall in love with it, you can purchase its license and use it anytime you wish to develop code for Allen Bradley Micrologix and SLC 500 families of PLCs instead of buying very pricy RSLogix 500 software developed by Rockwell Automation®.
LogixPro 500 software allows you to have a complete stand-alone PLC training system without the expense of a PLC and it is an ideal tool for learning the fundamentals of ladder logic programming that when it is used with my text, you have access to a very powerful PLC training system through your PC. The look, feel and operation of LogixPro 500 ladder rung editor is so closely mimics Rockwell’s world renown PLC editing software, that one needs to have a second look to be sure whose editor they’re using. Many workout exercise programs developed and are presented in the text are based on application of LogixPro 500 software hence you can run them when you have already downloaded the software.

Chapter 1 is devoted to an Introduction to Logic where I have included some information regarding Ladder Diagrams, exercises, implementation, design analysis of two interesting systems: a 2-floor up/down lifter and a 4-floor elevator system to show you how, just by thinking logically, you can design and implement an interesting and useful ladder diagrams to control typical mechanical systems simply through the use of plain relays and timers to speed up your learning process.

Chapter 12 is devoted to 22 complementary projects with solutions which will encourage readers to challenge what they have learned through the text concerning PLC programming skills. Even if a reader is unable to come up with a full solution for most of those projects on the first try, he will have the opportunity to examine a solution to any provided project and still learn.

Therefore, this book represents the best way to learn or be trained on Ladder Logic programming since it is like you are buying three different books: One for Theory, one for Lessons and a third one for Real applications (i.e. working on the 22 complementary typical PLC programming projects included).
