摘要
以开放式系统互联模型ISO/OSI为参考,详细描述了PROFIBUS通信协议的结构,包括物理层的数据传输技术、数据链路层的报文通信格式以及用户接口的各种应用规范.研究了PROFIBUS的三种协议规范PROFIBUS-DP、PROFIBUS-PA和PROFIBUS-FMS的的总线配置、主从站工作机制以及开发相关接口的方法,并就从站的软件流程进行了说明.分析和研究PROFIBUS现场总线协议具有重要的现实意义.
According to ISO/OSI normative model, the structure of the communication protocol of PROFIBUS is described fh＇st, including the data transfer technology of physical layer, the message format of data link layer and various application criterions of user interface. The distribution offieldbus, work mechanism of PROFIBUS-DP, PROFIBUS-PA and PROFIBUS-FMS is studied, as well as the methods to develop the corresponding interface. In addition, the workflow of the software is also introduced. Have a research on PROFIBUS protocol will be of great significance.
