摘要
针对Profibus-DP现场总线中用于连接主站与工业设备的从站设备的关键技术,提出一种基于双口RAM的Profibus-DP从节点设计方案。给出了从节点的硬件和软件总体设计方案,从节点核心模块的实现方案以及基于双口RAM的用户接口设计。
Aiming at the key technology for the master and slave device connection in Profibus-DP,the scheme for Profibus-DP slave node＇s design based on dual-port RAM was proposed,including that for the slave node＇s hardware and software design.The design should start from the implementation of node＇s core modules and the user interface based on dual-port RAM.
