摘　　要：鉴于通信问题是现场总线控制系统集成的一个主要问题 ,本文探讨了现场总线的拓扑结构 ,以Profibus -DP工控网为基础 ,分析了其通信机理和链接方式 ,并建立了基于PLC的主从站式控制现场总线网络。阐述了实现Profibus -DP变频器控制通讯的原理及方法 。Communication issue is the key problem for the integration of the fieldbus control system. In this paper, configuration of the fieldbus is discussed. Its communication principle and interlinkage mode are analyzed based on the Profibus-DP industry control network. And the network of the fieldbus was established on the base of the master-slave control of the PLC.The principle and method of communication in INVERTER with Profibus-DP are introduced. And the filedbus communication between SIEMENS PLC and ABB INVERTER was introduced.
