摘要
自2006年Profibus现场总线成为我国现场总线的国家标准(GB/T20540-2006)以来,Profibus-DP从站的开发已逐渐成为当今工业自动化控制及仪表领域的研究热点。针对该热点讨论了采用AT89S52和协议芯片SPC3设计了Profibus-DP从站,分别从Profi-bus-DP从站的硬件设计、软件设计和组网调试三方面展开较详细的讨论,并进行了组网调试。结果表明,该从站能够稳定可靠地运行,有力地促进了Profibus-DP现场总线的推广应用。
Since the Prefibas became our national fieldbus standard （GB/T 20540-2006 ） in 2006, developing Prefibus-DP slave stations has gradually become the focus of industrial automation and control as well as the instrumentation area. Aiming at this topic of general interest, the design and implementation of the Profibus-DP slave station by using AT89S52 and protocol chip SPC3 are discussed. The discussion covers three aspects in detail, i.e. , hardware design, software design and network debugging, The result of debugging shows that the station works stably and reliably, it effectively promotes the application of Prefibus-DP.
