基于 FPGA 的 Ethernet Powerlink 技术的实现磁

摘要

为满足工业自动化控制系统数据采集传输的实时要求,以Cyclone系列的EPC40F484为核心控制芯片,ENC28J60为网络接口芯片,实现了开源以太网协议Powerlink.利用Wireshark工具进行测试,实验结果表明,这种利用FPGA实现Powerlink的方法具有确定性好、实时性强的优点.%In order to meet the real -time requirements of data acquisition and transmission in the industrial automation control system ,cen-tering on the Cyclone series of EPC40F484 and making ENC28J60 as the Network interface chip ,the open Ethernet Powerlink has been im-plemented .By test of Wireshark ,the results verify that the method to implement Powerlink using FPGA has the advantages of well determin-istic and real-time .
