基于FPGA的EtherCAT从站节点开发

FPGA-based Development of EtherCAT Slave Node

随着实时工业以太网技术在工业自动化领域的发展和应用,德国倍福公司推出的EtherCAT技术尤其备受瞩目。EtherCAT技术的核心在于EtherCAT通信机制、EtherCAT主站和EtherCAT从站节点。EtherCAT从站节点通常是采用EtherCAT从站控制芯片和从站控制微处理器来设计实现的,对此提出了一种使用FPGA技术开发实现EtherCAT从站节点功能的方法,并验证了方法的可行性。

With the development and application of the real - time industrial Ethernet technology in industrial automation, EtherCAT technology introduced by Beckhoff is especially well received. The core of EtherCAT technology is the EtherCAT communication mechanisms, EtherCAT Master and EtherCAT Slave Node. EtherCAT slave node is usually designed by using EtherCAT slave controller chip and slave control microprocessor chip to achieve its function, this paper presents a method which is using FPGA technology to develop the EtherCAT slave node, and verifies the feasibility of it.
