Features: This book provides a detailed introduction to the working principles and usage methods of the FX2 series programmable logic controllers (PLCs) produced by Japan's Mitsubishi Corporation. The book is divided into 7 chapters. Chapter 1 introduces the basic structure and characteristics of hydraulic control systems. Chapter 2 focuses on the connection methods between PLCs and hydraulic control systems, along with common interface forms. Chapter 3 covers the hardware configuration and installation methods of PLCs, as well as the physical properties of input and output terminals. Chapter 4 discusses various programming soft elements of PLCs, including input and output points, timers, counters, status elements, constants, etc. This chapter also introduces the forms, characteristics, and usage methods of all basic PLC instructions. Chapter 5 covers the step-by-step sequential control instructions of PLCs, including their features and application methods. Chapter 6 primarily focuses on the function instructions of the FX2 series PLCs. This chapter is relatively lengthy, and mastering its content is key to proficiently applying PLCs. Chapter 7 provides some practical application examples, including hardware design, software design, and programming techniques. The main target audience of this book is technical personnel who are newly involved in PLCs or students from non-self-control majors in higher vocational colleges. Therefore, the book strives to present complete, well-organized, detailed, and easy-to-understand content on PLCs. This book is particularly suitable for beginners and also offers some reference value for engineering technicians researching PLC applications.
