摘　　要：Profibus-DP现场总线技术已经成为工业自动化控制及仪表领域的研究热点。针对现场总线的应用和发展现状,提出了基于Freescale S12微控制器与Profibus-DP协议芯片SPC3所构成的DP智能从站设计方法,并从Profibus-DP从站的硬件设计、软件设计二方面展开较详细的论述。使用结果表明,该从站能够稳定可靠地运行,促进了Profibus-DP现场总线的推广应用。The Profibus-DP fieldbus becomes hot spot of the develoment of automation and control. According to the current status of Fieldbus of the development and application,this paper presented software and hardware design method of PROFIBUS-DP intelligent slave station interface based on the PROFIBUS-DP protocol chip SPC3 and Freescale S12 MCU. The result of applying shows that the station works stably and reliably,it effectively promotes the application of Profibus-DP.
