Programmable Logic Controllers (PLCs) are the backbone of today's Industrial Automation systems. They are more and more often included in Technical curricula nowadays. This basic guide will take you from the very basic concepts, to put PLC code together, all the way up to briefly explore the steps to a successful project! No previous PLC coding experience is needed to begin exploring this fascinating technological world!

This book gives an introduction to Structured Text (ST), used in Programmable Logic Control (PLC). The book can be used for all types of PLC brands including Siemens Structured Control Language (SCL) and Programmable Automation Controllers (PAC). Contents: - Background, advantage and challenge when ST programming - Syntax and fundamental ST programming - Widespread guide to reasonable naming of variables - CTU, TOF, TON, CASE, STRUCT, ENUM, ARRAY, STRING - Guide to split-up into program modules and functions - More than 90 PLC code examples in black/white - FIFO, RND, 3D ARRAY and digital filter - Examples: From LADDER to ST programming - Guide to solve programming exercises Many clarifying explanations to the PLC code and focus on the fact that the reader should learn how to write a stable, robust, readable, structured and clear code are also included in the book. Furthermore, the focus is that the reader will be able to write a PLC code, which does not require a specific PLC type and PLC code, which can be reused. The basis of the book is a material which is currently compiled with feedback from lecturers and students attending the AP Education in Automation Engineering at the local Dania Academy, "Erhvervsakademi Dania", Randers, Denmark. The material is thus currently updated so that it answers all the questions which the students typically ask through-out the period of studying. The author is Bachelor of Science in Electrical Engineering (B.Sc.E.E.) and has 25 years of experience within specification, development, programming and supplying complex control solutions and supervision systems. The author is Assistant Professor and teaching PLC control systems at higher educations. LinkedIn: https://www.linkedin.com/in/tommejerantonsen/

The journey continues with a focus on advanced topics like cybersecurity in PLC systems and leveraging generative AI (GenAI), such as ChatGPT, to enhance productivity. By the end of this book, you’ll be able to design real-world projects using pseudocode and flowcharts, and implement those designs in structured text.What you will learn Explore and understand how to implement PLC programs in structured text Experiment with common functions in structured text Control the flow of a PLC program with loop and conditional statements Discover how to design a PLC program with pseudocode and flowcharts Implement common sorting algorithms such as bubble sort and insertion sort, and understand concepts such as Big O Understand the basics of cybersecurity to protect PLC-based systems Leverage ChatGPT for PLC programming Understand the basics of troubleshooting hardware and fixing common problems Who this book is for This book is for automation engineering students and individuals seeking entry-level knowledge of PLC programming with structured text and other modern computer science concepts to excel in the advanced automation landscape. No prior knowledge of PLC programming is required.

An in depth examination of manufacturing control systems using structured design methods. Topics include ladder logic and other IEC 61131 standards, wiring, communication, analog IO, structured programming, and communications.Allen Bradley PLCs are used extensively through the book, but the formal design methods are applicable to most other PLC brands.A full version of the book and other materials are available on-line at http://engineeronadisk.com

This series examines how and why PLCs are used in automated factories and describes its basic capabilities. The various types of communication that occurs between a PLC and other devices is examined and a demonstration of how to use an industrial PLC, including programming in ladder diagram, hardwiring, loading and running a program is given. This series also demonstrates programming in statement list format, hardwiring and general operation.

This book is an introduction to the programming language Ladder Diagram (LD) used in Programmable Logic Controllers (PLC). The book provides a general introduction to PLC controls and can be used for any PLC brands. With a focus on enabling readers without an electrical education to learn Ladder programming, the book is suitable for learners without prior knowledge of Ladder. The book contains numerous illustrations and program examples, based on real-world, practical problems in the field of automation. CONTENTS - Background, benefits and challenges of Ladder programming - PLC hardware, sensors, and basic Ladder programming - Practical guides and tips to achieve good program structures - Theory and examples of flowcharts, block diagrams and sequence diagrams - Design guide to develop functions and function blocks - Examples of organizing code in program modules and functions - Sequencing using SELF-HOLD, SET/RESET and MOVE/ COMPARE - Complex code examples for a pump station, tank control and conveyor belt - Design, development, testing and simulation of PLC programs The book describes Ladder programming as described in the standard IEC 61131-3. PLC vendors understand this standard in different ways, and not all vendors follows the standard exactly. This will be clear through material from the vendor. This means that some of the program examples in this book may not work as intended in the PLC type you are using. In addition, there is a difference in how the individual PLC type shows graphic symbols and instructions used in Ladder programming. Note: This is a book for beginners and therefore advanced techniques such as ARRAY, LOOPS, STRUCT, ENUM, STRING, PID and FIFO are not included.
