PROFIBUS现场总线技术及发展分析

Analysis of PROFIBUS Fieldbus Technology and Evolution Trend

分析PROFIBUS现场总线发展现状,对PROFIBUS-DP现场总线技术的协议结构、通信原理、网络系统结构和设备分类等网络技术问题进行了阐述。将PROFIBUS与基金会现场总线FF、LONWORKS、控制局域网CAN及HART总线等几种目前已成熟的现场总线技术进行比较、分析,提出了PROFIBUS在应用中的几点优势。PROFIBUS与其他网络协议兼容形成开放的系统是PROFIBUS现场总线应用技术及网络的发展趋势。

This paper describes the PROFIBUS Fieldbus and analyzes the present conditions of PROFIBUS Fieldbus. Some important network technology issues are described which include the protocol of PROFIBUS -DP, the principle of communication, the frame of network system and the classification of equipment etc. PROFIBUS - DP is compared with other existent fieldbuses including Foundation Fieldbus （FF）, LONWORKS, Control Area Network （CAN） and HART. And their advantages and disadvantages are analyzed. The application advantages of PROFIBUS are concluded. The evolution trend of PROFIBUS - DP whose application technology and development of network are analyzed and introduced.
