The Development of PC Intelligent Network Adapter Based on LonWorks Fieldbus

After the functional requisitions and fundamental structure of intelligent networks adapter have been described briefly, this paper presents in detail its design sheme consisting of both hardware and the software for management, the former being specified by analysis of designing objective, circuits, addressing mode and clash arbitration, and the latter by explanation of networks interface software and driver software. At last, the control networks and some application systems supported by it are also discussed.
