Features: This book takes the widely used Mitsubishi company's newly launched FX1s, FX1n, FX2n, and FX2nc series as examples to introduce the working principles, hardware structure, programming components, and instruction system of PLC (Programmable Logic Controller). It also covers the empirical design method for ladder diagrams, the design method for ladder diagrams of sequential control systems, the method of designing ladder diagrams based on relay circuit diagrams, and three methods of designing sequential control ladder diagrams based on sequential function charts. These design methods are easy for beginners to grasp and can be used to skillfully design ladder diagrams for any complex on/off control systems. The book also introduces the design and debugging methods of PLC control systems, methods to improve system reliability and reduce hardware costs, as well as PLC networking and communication.
In line with the teaching characteristics of vocational and technical colleges, the practical training section has been strengthened, including a guide to the use of programmers and programming software, as well as an experimental manual with a large number of experiments. Each chapter is accompanied by an appropriate number of exercises, and reference answers are provided for some of the exercises. This book can be used as a textbook for electrical engineering and automation, industrial automation, applied electronics, computer applications, mechatronics, and other related majors in colleges and universities. It can also be used for self-study by engineering technicians or as training material.
