In this article, we describe the architecture of the industrial controllers supporting Industrial Ethernet for motion control systems. We targeted and analyzed PROFINET, EtherCAT, POWERLINK, and SERCOS III, and applied the proposed design derived from the analysis to a prototype of an EtherCAT master controller. We evaluated an FPGA prototype cooperating with a Geode processor (500 MHz) running standard Linux. The processing time results show that the proposed architecture is acceptable.
