Features: This book is written based on the current situation where many higher education institutions have merged the original two courses, "Factory Electrical Control Equipment (Technology)" and "Programmable Logic Controllers," into a single course called "Electrical Control and Programmable Logic Controllers." It fully considers the practical applications and development of electrical control technology. With a focus on practical engineering applications and ease of teaching, the book primarily introduces electrical control technology and system design, as well as the principles and applications of programmable logic controllers (PLCs). It systematically elaborates on general methods for analyzing and designing electrical control systems. The book is divided into two parts and 11 chapters, covering topics such as common electromagnetic low-voltage electrical appliances, other common low-voltage principles, the features and technical specifications of programmable controllers, the basic instruction system of PLCs, step control instructions and sequential function flowcharts, function instructions, special expansion modules of programmable controllers, PLC networks and communication, and application design methods for PLCs. Each chapter ends with a set of review questions. In the PLC section, the book takes the FX2N as an example to systematically discuss the construction principles, hardware structure, internal soft components, and instruction system of PLCs. Building on this foundation, it provides detailed solutions for the increasing demand for analog control, positioning control, network communication, and data transmission in the widespread automation applications of PLCs. This book can be used as a teaching material for undergraduate, junior college, TV university, and part-time university students majoring in automation, industrial automation, electrical technology, mechatronics, and related fields, as well as "Electrical Control and Programmable Logic Controllers" and similar courses. It can also serve as a reference and self-study guide for automation engineers engaged in design and research related to these topics.
