Features: A programmable controller is an electronic system designed for digital operation and is specifically intended for industrial environments. It employs programmable memory to store instructions for executing logical operations, sequential control, timing, counting, and arithmetic operations internally, and controls various types of machinery or production processes through digital and analog outputs. PLCs expand their functionality based on certain principles, and therefore, programmable controllers have gained widespread application in industries such as automobiles, steel, aerospace, shipbuilding, chemical engineering, textiles, food, papermaking, and military due to their advantages of simplicity, ease of operation, high reliability, flexibility, compact size, and long service life.
This book is based on the three high-performance small PLCs currently widely used in China and systematically elaborates on the structure, working principles, hardware and software systems of programmable controllers, as well as the systematic design process of PLC control systems from design to installation to maintenance. It also provides a detailed introduction to PLC networking technologies. The content of this book is novel, easy to understand, and written in plain language, with theory closely linked to practice. Through examples, it introduces the specific applications of PLCs in different industries in detail. In terms of writing style, it emphasizes the combination of theory and practice. Not only are examples inserted at appropriate times in each chapter to help readers deepen their understanding and mastery of the content, but a comprehensive example is also provided as the final chapter to assist readers in referencing and improving their comprehensive application capabilities of programmable controllers.
This book can serve as a textbook for undergraduate students in majors such as mechatronics, automation, electrical technology, and other related fields, as well as a reference book for a broad range of engineering.
