New Development of the Lonworks Field-bus Technology

Internet, as a global and enormous computer network system, solves a lot of difficulties about interactive communication. To connect industry local automation process equipment in global to be an open, point to point, inter-operable computer network system, and control the equipment from a long distance in any corner of the world, the Lonworks field-bus technology provides simple solution for many network problems about designing, cre- ating, installing and maintaining the equipment. This paper introduces the formation and development of the Lon- works field-bus, discusses its advantage and disadvantage and points out the core technology and network topology structure, and gives its development and application; finally, puts forward the prospect and new development trend.
