【Abstract】 A brief introduction of LonWorks FCS and the methods of developing fieldbus control nodes are introduced. The principles of designing the digital I/O circuits and the analog I/O circuits are narrated in detail. At last, some empirical essentials and solution methods in designing fieldbus control nodes are given. This paper is also instructive to the development of other fieldbus control system.更多还原
