Abstract: As the development of the Ethernet technology, it has become the developing trend
combining the embedding system with the Ethernet in the industry control system field. A field device running under the real-time operating system μC/OS-II was developed in this paper. This device accomplished the necessary supervisory and control tasks, as well as the TCP/IP communication based on a real-time operating system. It can act as a Web Server in the industrial Ethernet environment.
