基于ARM的PROFIBUS-DP智能主站设计与研究

摘要

In this paper,the deveIopment method of ARM9 LPC3250 and HiIscher PROFIBUS-DP master protocoI chip based on COM-CN-DPM to ensure the reIiabiIity of PROFIBUS-DP master station communication and shorten the deveIopment cycIe. The successfuI transpIantation of Linux operating system based on 2.6 kerneI,and in the Linux operating system on the successfuI architecture of embedded BOA server,reaIized through the Internet to a remote fieId bus equipment controI,which enhace the stabiIity,the reaI-time performance of the whoIe system and the subsequent expansion function.%由于PROFIBUS-DP主站技术复杂，在国内研究较少，自主研发产品的功能有限、智能化不足的现状，许多中小企业很难全面展开应用。采用基于ARM9的LPC3250与赫优讯PROFIBUS-DP主站协议芯片COM-CN-DPM的开发方案保证了PROFIBUS-DP主站通信的可靠性以及缩短了开发周期。并成功地移植了基于2．6内核的Linux操作系统，并在Linux操作系统上成功架构了嵌入式BOA服务器，实现了通过互联网对远程现场总线设备的控制，在操作系统前提下进行PROFIBUS-DP主站模块通信，增强了整个系统的稳定性、实时性以及后续的扩展功能。
