S7-200是西德西门子公司的产品，其注册商标为SIMATIC。
1．西门子公司的产品早是1975年投放市场的SIMATIC S3，它实际上是带有简单操作接口的二进制控制器；
2．1979年，S3系统被SIMATIC S5所取代，该系统广泛地使用了微处理器；
3．20世纪80年代初，S5系统进一步升级——U系列PLC，较常用机型：S5-90U、95U、100U、115U、135U、155U
4．1994年4月，S7系列诞生，它具有更国际化、更高性能等级、安装空间更小、更良好的WINDOWS用户界面等优势，其机型为：S7-200、300、400
5．1996年，在过程控制领域，西门子公司又提出PCS7（过程控制系统7）的概念，将其优势的WINCC（与WINDOWS兼容的操作界面）、PROFIBUS（工业现场总线）、COROS（监控系统）、SINEC（西门子工业网络）及控调技术溶为一体
6．现在，西门子公司又提出TIA（Totally Integrated Automation）概念，即全集成自动化系统，将PLC技术溶于全部自动化领域。
