Features: This book takes the S7-200 series PLC widely used in China as an example to introduce the working principles, hardware structure, instruction system, and usage methods of PLC programming and simulation software. It also covers the empirical design method for ladder diagrams in digital control systems, relay circuit conversion method, and sequential control design method. These methods are easy to learn and use, saving a significant amount of design time. The book also explains the usage of analog modules, the design methods for subroutines and interrupt programs, the application of high-speed counters and high-speed outputs, the communication network and communication implementation of PLCs, PID closed-loop control, measures to improve the reliability of PLC control systems, and other application-related issues. Each chapter is accompanied by exercises, and the appendix provides a rich experimental guide and answers to some of the exercises. The programming software for S7-200 is designed with numerous programming wizards for advanced applications, allowing users to automatically generate user programs by inputting some parameters. This book details the usage methods of commonly used programming wizards. The sister book, PLC Programming and Applications, provides a more comprehensive and in-depth introduction to S7-200, and the accompanying CD-ROM includes the Chinese programming software for S7-200, system manuals in both Chinese and English, product catalogs, and program examples. This book can serve as a textbook for vocational and technical colleges in electrical and mechatronics integration programs, as well as for self-study by engineering technicians.
