Abstract

First, in this paper we present the integral structure of RS-485 fieldbus network in practical industrial applications. Through designing and implementing RS-485 fieldbus control systems, we gained much experience in configuration of resistor termination network, noise elimination on floating transmission lines, transmission control, multi communication station addressing and flow control. Then we discuss those points in detail. Finally, we consider the problems of network reliability and multi station real time data acquisition and control.
