摘　　要：作为实时工业以太网技术的优秀代表,Powerlink协议开源、易移植、实时性好,运用时隙和轮询过程的混合方法来实现数据的同步传输,被广泛应用于工业控制领域。通过在FPGA平台上构建NIOS Ⅱ软核处理器,运行协议栈C语言部分,同时借助网络接口芯片ENC28J60与管理节点进行通信,从而完成一个受控节点的设计。开展基于FPGA平台的Powerlink通信协议研究与设计,能够为后续开发基于Powerlink协议的智能型测量和控制仪表做好技术储备,实现与原有系统的综合集成。联合调试结果表明,该Powerlink受控节点的实时性、确定性优势明显。Powerlink protocol, an outstanding representative of real time industrial ethernet, has the advantages of open source and portable, and so it is widely used in the field of industrial control. It a- chieves the target of synchronous transmission by using hybrid method, which consists of time slot and polling. The protocol runs on NIOS II processor and communicates with managing node using ENC28J60. By conducting Powerlink protocol research and design based on FPGA platform, it can be good for the subsequent development of intelligent measurement and control instrument, the integration of original system. The debugging result shows that the controlled node works well and has obvious ad- vantages, such as real time and determination.
