Features: Programmable controllers represent another milestone in the application of microcomputer control technology, following microcontrollers and STD bus. Due to their extremely high reliability and highly convenient application, they are rapidly being adopted and developing quickly worldwide. They have long surpassed the limitations of purely switch-based control and have entered fields such as process control, position control, communication networks, and graphical workstations, becoming indispensable core control components in electromechanical and process control systems. This book introduces the origins, current status, and development of programmable controllers. Taking the currently most representative programmable controllers from abroad—the Mitsubishi FX2N series (FX2N, FX2NC, FX1N, FX1S)—as examples, it comprehensively discusses the structural principles, hardware and software architecture, components, instruction systems, and other aspects of programmable controllers. Additionally, it covers the design and programming methods of programmable controller control systems, including topics such as switch-based control, analog control, position control, data I/O, communication, and networking, along with exercises and practical examples. This book is primarily intended as a textbook for undergraduate students in electrical control and mechatronics. It also serves as an introductory guide for technicians and workers in the mechatronics industry to update their knowledge structure and apply new technologies. The book is based on the latest foreign technical materials and is an excellent reference for graduate students and designers of domestically produced programmable controllers.
