Development on PROFIBUS-DP Communication Interface of Intelligent Analysis Instrument

Zheng Yuan

Abstract

The structure and the function of PROFIBUS-DP bus communication protocol chip SPC3 is introduced.The extended functions of PROFIBUS protocol DPV1 are analyzed.Based on the intelligent analysis instrument,the hardware and software design and the implementation method of PROFIBUS-DP intelligent slave station interface are presented.By using the PROFIBUS-DP protocol chip SPC3 and AVR_mega16 series single chip,the module of the intelligent slave station interface with PROFIBUS-DP interface is developed.By adopting ‘the core board plus the interface board’ method,modularization technology and top-down method are used.At last,the system of PROFIBUS-DP is realized.
