调知识的实用性，几乎每章中都配有大量实用的例题，便于读者模仿学，另外每章配有题供读者训练之用。大部分实例都有详细的软件、硬件配置清单，并配有接线图和程序。《西门子S7-200PLC完全精通教程》配光盘中有重点内容的程序和操作视频资料。《西门子S7-200PLC完全精通教程》目录：篇 基础入门篇章 可编程控制器（PLC）基础1.1 概述1.1.1 PLC的主要特点1.1.2 PLC的应用范围1.1.3 PLC的分类与性能指标1.1.4 PLC与继电器系统的比较1.1.5 PLC与微机的比较1.1.6 PLC指令本身占有的时间（3）指令条数 6．由于采用集中采样。集中输出的方式。存在输入/输出滞后的现象，即输入/输出响应延迟。 二．PLC与继电器控制系统、微机区别 1．PLC与继电器控制系统区别 前者工作方式是“串行”，后者工作方式是“并行”。 前者用“软件”，后者用“硬件”。 2．PLC与微机区别 前者工作方式是“循环扫描”。后者工作方式是“待命或中断” PLC 编程方式 PLC*突出的优点采用“软继电器”代替“硬继电器”。用“软件编程逻辑”代替“硬件布线逻辑”。 PLC编程语言有梯形图、布尔助记符语言，等等。尤其前两者为常用。 icro/WIN16 V2.1软件包，但是它只支持对S7-21x同样具有的功能进行编程。 STEP 7-Micro/DOS不能对CPU 221/222/224/224XP/226编程。如果使用PG/PC的串口编程，则需要使用PC/PPI电缆。 如果使用STEP 7-Micro/WIN32 V3.1编程软件，则也可以通过SIMATIC CP 5511或CP 5611编程。在这种情况下，通讯速率可高达187.5kbit/s。 可以利用PC/PPI 电缆和自由口通讯功能把 S7-200 CPU 连接到许多和RS-232标准兼容的设备。 有两种不同型号的 PC/PPI 电缆2.1 软件安装和设置2.1.1 安装条件2.1.2 安装2.1.3 安装SP升级包(Service.Pack)2.1.4 Micro/WIN指令库2.2 STEP7-Micro/WIN简介2.2.1 STEP7-Micro/WIN窗口元素2.2.2 项目及其组件2.2.3 定制STEP7-Micro/WIN2.2.4 使用帮助2.3 编程计算机与CPU通信2.3.1 设置通信2.3.2 PLC信息2.3.3 实时时钟2.4 系统块设置2.4.1 通信口2.4

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 advantage of plc* is to use "soft relay" instead of "hard relay". Replace "hardware wiring logic" with "software programming logic". PLC programming languages include ladder diagram, Boolean mnemonic language, and so on. In particular, the first two are commonly used. Micro/win16 v2.1 software package, but it only supports the programming of the same functions of s7-21x. Step 7-micro/dos cannot program CPU 221/222/224/224xp/226. If you use pg/pc serial port programming, you need to use pc/ppi cable. If step 7-micro/win32 v3.1 programming software is used, it can also be programmed 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 compatible with RS-232 standard by using pc/ppi cable and free port communication function. There are two different models of pc/ppi cable 2.1 software installation and setting 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
