摘　　要：总线桥是指通过一个自行定义的双向并行通信协议,获得总线间的高速数据通信能力。同时,间接实现多种总线标准的协议转换。重点介绍RS232/485接口的现场设备连到PROFIBUS网络的通信协议及其核心硬件结构。The bus-bridge is defined as a bilateral parallel communication protocol to obtain the high-speed data communications among the bus. At the same time, it can achieve the protocol conversion among the different buses. This paper focuses on the communication protocol and its hardware structure to connect the PROFIBUS network and the field devices with the interface of RS232/485.

关 键 词：总线桥 协议转换 PROFIBUS 通信协议
