在这一系列讲座中,将陆续介绍一种工业控制领域有革命性意义的新兴技术-现场总线技术的概况以及几种流行的现场总线 FF、 Profibus、 LonWorks、 CAN、 HART等,使读者对现场总线技术有一个比较全面的了解.本讲主要介绍由于采用了双向、串行、数字化通信后,可满足自动控制系统实时、可靠通信要求的通信模型,这是现场总线系统不同于传统控制系统的一个特点,比较了几种典型的现场总线,简要介绍了 LonWorks和 HART总线,并对现场总线的标准化和发展趋势进行了探讨.
In this series of lectures, we will introduce a revolutionary industrial control field of emerging technologies - an overview of fieldbus technology and several popular field bus FF, Profibus, LonWorks, CAN, HART, so that readers on the scene The bus technology has a more comprehensive understanding.This talk mainly because of the use of two-way, serial, digital communications, automatic control system to meet real-time, reliable communication requirements of the communication model, which is different from the traditional field bus system control system One feature compares several typical fieldbuses, briefly introduces LonWorks and HART bus, and discusses the standardization and development trend of fieldbus.
