PROFIBUS-DP高速现场数据通信网络的组建

The construction of a high-speed fieldbus data communication network based on PROFIBUS-DP

介绍了PROFIBUS现场总线技术的特点并组建了PROFIBUS DP高速数据通信网络。讨论了该网络的组态、STEP7程序的编制以及现场设备GSD文件的建立方法。分析了网络数据传输的实时性与可靠性,并采用组态软件MCGS实现了上位机对PROFIBUS DP网络的实时监控。

The paper presents the characteristics of the PROFIBUS fieldbus technology and the construction of the high-speed data communication network,and discusses the configuration of the network,the S7 programs,the method of compiling GSD files for fieldbus devices,and analyses its real-time performance and the reliability.The paper also describes the application of the MCGS configuration software to monitoring and controlling the PROFIBUS network.
