Following more and more equipment in adoption of Modbus RTU protocol, this paper designed a kind of conversion de-vice of Modbus protocol and Profibus-DP protocol in order to follow the development of network automation. The Modbus network was connected to the Profibus-DP network through the device. Introduction was made to protocol modes of Profibus-DP and Modbus of two kinds of field buses and analysis was made to the transfer method of two kinds of field buses. This paper raised transfer circuit design and software design of singlechip machine system. Experiment proved the correctness and practicality of data transfer.
