摘要
研究、应用现场总线和PLC支持下的分布式控制系统,是目前工厂自动化得以实现的有效途径之一。在论述PROFIBUS基本特征和SIMATICS7系列PLC通信功能的基础上,设计了污水处理厂的分布式I/O控制系统,提出了现场总线和PLC的发展方向。
In now days, the research, and application of distributed control system is one of main ways for realizing factory automation, which based on field bus and PLC technique. In this article, we discuss the basic features of PROFIBUS and the communication functions of SIMATIC S7. As an example, we design a distributed I/O control system for sewage factory. At last, the developing tendency of Field bus and PLC is presented.
