For the practicality of knowledge adjustment, almost every chapter is equipped with a large number of practical examples, which is convenient for readers to imitate and learn. In addition, every chapter is equipped with questions for readers' training. Most examples have detailed software and hardware configuration lists, and are equipped with wiring diagrams and procedures. The "Siemens S7-200PLC complete proficiency tutorial" is equipped with the program and operation video materials with key contents in the CD. "Siemens S7-200PLC complete proficiency tutorial" directory: Chapter 1 basic introduction chapter 1 programmable controller (PLC) foundation 1.1 overview 1.1.1 main features of PLC 1.1.2 application scope of PLC 1.1.3 classification and performance index of PLC 1.1.4 comparison between PLC and relay system 1.1.5 comparison between PLC and microcomputer 1.1.6 time occupied by PLC instruction itself (3) number of instructions 6. Due to the use of centralized sampling. Centralized output mode. There is input / output lag, that is, input / output response delay. 2、 The difference between PLC and relay control system and microcomputer 1. The difference between PLC and relay control system is that the former works in "serial" mode and the latter works in "parallel". The former uses "software", while the latter uses "hardware". 2. The difference between PLC and microcomputer is that the working mode of the former is "cyclic scanning". The latter works in the "standby or interrupt" PLC programming mode. The outstanding adv through SIMATIC CP 5511 or CP 5611. In this case, the communication rate can be as high as 187.5kbit/s. The S7-200 CPU can be connected to many devices co 2.1.1 installation conditions 2.1.2 installation 2.1.3 installation of SP upgrade package (service.pack) 2.1.4 micro/win instruction library 2.2 introduction to STEP7 micro / win 2.2.1 STEP7 micro / win window elements 2.2.2 items and their components 2.2.3 customized STEP7 micro / win 2.2.4 using help 2.3 programming computer and CPU communication 2.3.1 setting communication 2.3.2 PLC information 2.3.3 real time clock 2.4 system block setting 2.4.1 communication port 2.4
