This book is oriented to the people that work on and troubleshoot PLCs on the factory floor. It is directed at the actual problems and conditions that will be encountered within a realistic setting. The text is designed to present a clear, concise picture of how PLCs operate to the person that wishes to learn more about them.
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!
What makes a powerful and results-driven Professional Learning Community (PLC)? The answer is collaborative work that expands the emphasis on student learning and leverages individual teacher efficacy into collective teacher efficacy. PLC+: Better Decisions and Greater Impact by Design calls for strong and effective PLCs plus—and that plus is YOU. Until now, the PLC movement has been focused almost exclusively on students and what they were or were not learning. But keeping student learning at the forefront requires that we also recognize the vital role that you play in the equation of teaching and learning. This means that PLCs must take on two additional challenges: maximizing your individual expertise, while harnessing the power of the collaborative expertise you can develop with your peers. PLC+ is grounded in four cross-cutting themes—a focus on equity of access and opportunity, high expectations for all students, a commitment to building individual self-efficacy and the collective efficacy of the professional learning community and effective team activation and facilitation to move from discussion to action. The PLC+ framework supports educators in considering five essential questions as they work together to improve student learning: Where are we going? Where are we now? How do we move learning forward? What did we learn today? Who benefited and who did not benefit? The PLC+ framework leads educators to question practices as well as outcomes. It broadens the focus on student learning to encompass educational equity and teaching efficacy, and, in doing so, it leads educators to plan and implement learning communities that maximize individual expertise while harnessing the power of collaborative efficacy.
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.
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/
