现场总线控制系统是从80年代中期发展起来的。经历了十几年的时间,现场总线控制技术已经被广泛应用于汽车、造纸、纺织、烟草机械、石油化工、电力及楼宇自控等各个控制领域。现场总线控制技术由于其巨大的技术优势,被认为是工业控制发展的必然趋势,将逐步取代传统的PLC点对点接线的控制方法。本文将分几个部分介绍现场总线控制系统的基本理论及其应用。
Fieldbus control system was developed from the mid-80s. After more than ten years of experience, fieldbus control technology has been widely used in various control fields such as automobile, papermaking, textile, tobacco machinery, petrochemical industry, electric power and building automatic control. Due to its huge technical advantages, fieldbus control technology is considered as the inevitable trend of industrial control development, and will gradually replace the traditional control method of PLC point-to-point connection. This article will be divided into several sections introduce the basic theory of fieldbus control system and its application.
