Widely used across industrial and manufacturing automation, Programmable Logic Controllers (PLCs) perform a broad range of electromechanical tasks with multiple input and output arrangements, designed specifically to cope in severe environmental conditions such as automotive and chemical plants. Programmable Logic Controllers: A Practical Approach using CoDeSys is a hands-on guide to rapidly gain proficiency in the development and operation of PLCs based on the IEC 61131-3 standard. Using the freely-available* software tool CoDeSys, which is widely used in industrial design automation projects, the author takes a highly practical approach to PLC design using real-world examples. The design tool, CoDeSys, also features a built in simulator/soft PLC enabling the reader to undertake exercises and test the examples. Key features: * Introduces to programming techniques using IEC 61131-3 guidelines in the five PLC-recognised programming languages. * Focuses on a methodical approach to programming, based on Boolean algebra, flowcharts, sequence diagrams and state-diagrams. * Contains a useful methodology to solve problems, develop a structured code and document the programming code.* Covers I/O like typical sensors, signals, signal formats, noise and cabling. * Features Power Point slides covering all topics, example programs and solutions to end-of-chapter exercises via companion website. No prior knowledge of programming PLCs is assumed making this text ideally suited to electronics engineering students pursuing a career in electronic design automation. Experienced PLC users in all fields of manufacturing will discover new possibilities and gain useful tips for more efficient and structured programming. * Register at

The second of the graphic languages that are defined in IEC 61131-3 is function block diagram (FBD). The structure of FBDs is consistent with the structure of ladder diagrams (LDs) with respect to graphic symbols, signal flow, order of execution, and structuring of the code. FBD code is divided into ...
