摘要
现场总线作为计算机技术、通信技术以及控制技术高度集成与综合的产物,已经成为当今自动化领域技术发展的热点之一。它主要是连接智能现场设备与自动化系统的全分散、数字化以及多变量的通信网络。Profinet以其实时太网、分布式自动化、故障安全以及网络安全的特点,在PLC控制系统中得到广泛应用。本文就对基于Profinet总线的PLC控制系统组网配置进行具体研究。
The fieldbus as the computer technology, communication technology and the product of a highly integrated and comprehensive control technology, has become a hot topic in today＇s automation technology development. It is mainly connected intelligent field devices and automation systems, which are distributed, digital and multivariate communica- tions network. Profinet has the characteristics of real-time network, distributed automation, fail safe, and network security, is widely used in the PLC control system. In this paper, the network configuration for specific research of PLC control system based on profinet fieldbus are described.
