摘要
深入研究了PROFIBUS现场总线的通信机制、协议模型和技术特点,详细阐述了PROFIBUS-DP的网络组态、主站和从站以及主站之间的数据通信、系统外围硬件电路的连接和整体设计方案。整个系统具有结构简单、成本低廉等优点,实现了终端用户对远程数据采集系统的查询和控制,具有较大的使用推广价值。
The paper describes the thorough study on the communications mechanism and technical characteristics of PROFIBUS, treats of the network configuration, the data communication between main station and secondary station, and hardware design of the system, and provides the connecting scheme of the circuit. Users could access the wireless data collection system with end device, and this is of great popularity value for its simple structure and low cost.
