摘要
提出了一种采用FPGA器件实现PROFIBUS-DP从站控制器的解决方案,分析了PROFIBUS-DP链路层规范,给出了该控制器的总体结构和逻辑设计。该控制器可以完成PROFIBUS-DP协议数据链路层的功能,结合外部微处理器,可构造一个完整的智能PROFIBUS-DP从站。该控制器可以支持最大至12M的通信波特率。
A solution was put forward, to design a PROFIBUS-DP slave station controller based on FPGA. PROFIBUS- DP DLL （Data Link Layer） Protocol was analyzed, and the controller＇s whole structure and logic design were detailed. The controller can afford the functions that PROFIBUS-DP DLL protocol specified, and implement a DP slave station when integrated a MCU. The highest communication rate of this station can go up to 12Mbps.
