Intelligent meter modbus protol converter is a low-cost intelligent communications interface protocol converters。Instrumentation for the scene and actuator control。 Modbus industrial area is now the world's most popular one of the agreements。The agreement with the traditional support RS-232, RS-422, RS-485 and ethernet interface equipment。Many industrial equipment including plc, dcs, Intelligent instrumentation in use so as modbus communication between the standards。With it, the different manufacturers can even control equipment for industrial network for centralized monitoring。 Where is the RS232/485 interface modbus equipment can be used modbus bus bridge achieve profibus interconnection。In accordance with profibus communication data and the modbus communication of data mapping,profibus modbus to achieve the transparent data communication。
This paper introduces the modbus intelligent protocol converter concept, have a definition. introduced intelligent protocol converter systems, analysis of intelligent protocol converter works。Modularization of the system analysis, which focuses on the achievement of the relevant issues with the interface initialization, and data exchange design and implementation。
