Design and realization of EtherCAT master

EtherCAT is widely used in the numerical control, machinery processing field etc. EtherCAT solutions and products are mainly imported. Based on studying EtherCAT standard and EtherCAT network system thoroughly, this article presents a kind of feasible, low cost of design for EtherCAT master, which is called simple EtherCAT master, including hardware and software design, and project a plan to test the designed EtherCAT master.
