摘要
Ether CAT是一类比较成熟的工业以太网现场总线,专用于运动控制领域。系统通信采用主从结构,其中从站控制器ESC(Ether CAT Slave Controller)是从站模块实现Ether CAT协议数据通信的关键芯片,对从站控制芯片进行自主研究设计有助于深入了解Ether CAT总线技术,并实现工业现场总线自主化设计。依据从站控制器ESC的功能,基于FPGA设计了ESC的子功能模块FMMU(Field Memory Management Units),通过主站对从站进行逻辑写操作验证了FMMU功能模块的正确性。仿真结果表明,基于FPGA的FMMU功能模块的实现方案可行。
Ether CAT is a type of mature industry Ethernet field bus technology,escpecially in motion control system. This communication system uses master and slave structure. The ESC（ Ether CAT Slave Controller） is a critical microchip for communication protocol implementation,and it＇s helpful for deeply understanding the technique of the Ether CAT and for autonomous design of industry Ethernet field bus technology.Based on the function of Ether CAT slave controller,the basic function FMMU is designed. The results show that implementation of FMMU is completely feasible based on FPGA（ Field-Programmable Gate Array）.
