基于USB接口的PROFIBUS DP智能从站

PROFIBUS DP Intelligent Slave Based on USB Interface

针对USB和PROFIBUS总线的应用现状,提出一种基于USB接口将主机接入PROFIBUS的实现方案,对核心部件的软硬件设计进行了详细的叙述。采用高速USB芯片CY7C68013,利用其GPIF可以很好地与PROFIBUS模块接口,扩展主机与PROFIBUS总线连接。

According to the application of USB and PROFIBUS, this paper proposed a typical realization of connecting the host with PROFIBUS based on USB interface. The designing of primary components was elaborately presented on hardware and software respectively. Adopting GPIF（General Programmable Interface） of the high-speed microprocessor CY7C68013 will have an easy access to the PROFIBUS module, and it will make it easy to develop connect between Host and PROFIBUS.
