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 an 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 trial version of LogixPro PLC programming software on your personal computer and ready to start learning about ins and outs of Allen Bradly family of PLCs. The exercises in this text are designed to familiarize you with the operation of the 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 simulator software and you will be enough time to do all your exercises with it.. The following materials are included in the second edition of this text: Chapter 1 have included some information regarding Ladder Diagrams and exercises. Also included is 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 interesting and useful ladder diagrams to control typical mechanical systems simply through the use of plain relays and timers. In chapter 2- You are provided with a link to download free trial version of LogxiPro simulator software and solutions of the exercises to familiarize you with the operation of software that will speed up your learning process. The application of any PLC simulator software typically has significant impact on the learning process for students since one can view an execution of his developed code in action. In chapter 4 I have included a section on 'How to start developing a PLC control program?' in which I discuss development of different PLC based processes through analyzing and implementing two PLC circuit programs to show you how you can use logic to generate PLC control programs based on a given problem specifications in the real world. 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 some 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)
