摘要
介绍了Ethernet和Profibus-DP现场总线技术,阐述了结合二者来组建现场总线控制系统。以冷扎电解清洗线系统为例具体描述了系统的构成。系统在逻辑结构上分为两层:网络控制层和现场设备层,网络控制层采用工业以太网,Profibus用于现场设备层。用SIMATICS7进行了网络组态以及硬件组态,并实现了监控软件WinCC与S7的动态连接。
A fieldbus control system based on Ethernet and Profibus-DP is introduced in this paper,The structure of the system is described,The system is logically composed of two layer,network control layer and field device layer.Ethernet is adopted in network control layer.Profibus is applied in field device layer.The configuration and programming are accomplished by using SlMATIC S7.S7 and WinCC monitoring software are linked dynamically.
