基于I／A Series的控制系统通信网络研究与设计

结合理论与实际应用，对I／A Series DCS控制系统在数据通信方面的特点和方法进行了探讨，通过对FOXBORO公司的I／A Series控制系统网络构架的解析，阐明了各层通信之间的关系，重点对现场总线层通信进行了论述，对其中的Bitbus总线在DCS控制系统的基本结构和通信方式进行了研究。

Network Design and Implementation Based on I/A Series Control System

Data communication is the core of the DCS control system, it is a specific carrier to achieve the control program, the characteristics and methods are discussed combining of theory and practical application of the I/A Series DCS control system in data communications. This paper illustrates the relationship between the layers of communication through the analysis of FOXBORO company＇s I/A Series control system network architecture, it emphasis on the field bus level communication, and it studies the basic structure and means of communication of DCS control system for BITBUS.
