摘　　要：PROFIBUS_DP用于现场层的高速数据传送,主站周期性地读取从站的输入信息并向从站发送输出信息。在种类繁多的现场总线中,PROFIBUS_DP以高速、可靠、低成本通信的优势,用于设备级控制系统与分散式I/O的通信。PROFIBUS_DP transfer the field data with high-speed. Master station read the information from the slave station circularly and send the information to the slave station circularly. All kinds of the field-bus, PROFIBUS_DP is not expensive and high-speed, so PROFIBUS_DP is used to the communication between the machine control system and distributed I/O.
