摘要
以ARM9微处理器与VxWorks操作系统为基础设计实现冗余PROFIBUS-DP主站控制器。详细讨论了冗余D P主站控制器对从站的管理维护以及冗余通信与主备切换的实现方法,并提供了与上位机通信的以太网接口,通过该接口可以对冗余D P主站组态并监控运行状态。本设计对国内冗余D P主站方面的研究提供了一种参考。
A kind of redundant DP master controller was designed and developed in this paper based on ARM9 microprocessor and VxWorks operating system. And detailed discussion was made of the redundant DP master from the station management, redundant communications and switching. Also, the Ethernet interface which communicates with PC was designed to achieve its configuration and status monitoring. This paper provides a reference for domestic research of redundant DP master.
