摘　　要：为以较低的成本在国产伺服驱动器上实现具有较高性能的现场总线通信协议,掌握国家推荐性标准POWERLINK现场总线标准的关键技术,对POWERLINK总线技术进行了研究,提出了一个基于FPGA的POWERLINK现场总线控制器的设计方法。该方法在FPGA内部使用NIOS软核为CPU运行POWERLINK总线协议,同时使用硬件描述语言VHDL实现了一个双口RAM和伺服的DSP通信,通过实验验证了设计的可靠性和正确性。In order to realize a high-performance fieldhus communication protocol on servo drive with a low cost and master the key technology of national recommended standard the POWERLINK fieldbus, POWERLINK fieldbus technology is studied, and a POWERLINK controller design method based FPGA is proposed. This method uses the NIOS soft-core CPU in the internal FPGA to run POWERLINK protocol, and it also designs a dual-port RAM with a hardware description language VHDL to com- municate with servo DSP. The reliability and accuracy of the design is proved through experiments.
