经济实用的PLC及网络冗佘技术在地铁BAS中的应用

摘要

With the practical application of the Metro project, this paper describes how to realize system redunduncy with software technology based on Rockwell Control Logix redundant system with simple network (Ethernet) configuration, so as to save hardware cost and improve system reliability.%结合地铁工程的实际应用,阐述基于罗克韦尔公司Control Logix冗余系统并简化网络配置(以太网)下,通过软件技术实现系统冗余的方法,从而降低硬设备投资并提高系统可靠性.
