Abstract

Both structure and function of PROFIBUS-DP bus communication protocol chip VPC3 were introduced,and its DPV1 and DPV2's extended functions were analysed.Then,based on intelligent analysis instrument,the hardware and software design and implementation method of DPV1 intelligent slave station interface were presented,and module of intelligent slave station interface with PROFIBUS-DP interface developed by using chip VPC3 and AVR_mega128 single chip,and adopting the core plus interface board method,and modularization technology and top-down method.At last,the PROFIBUS-DP system has been realized.
