冗余系统在煤楼储装运系统中的应用研究

摘要

阐述了PLC冗余系统的概念、架构和基本的工作原理,结合自身实践对冗余系统的组态结构、系统编程及系统性能测试作了比较完整的介绍.冗余系统架构灵活、编程简单、稳定可靠,在减少停车时间,减员增效等方面作用明显.%The concept, structure and basic principle of PLC redundant system are expounded, and the configu ration structure, system programming and system performance testing of the redundant system on the base of practice are completely introduced. The redundant system architecture is flexible, stable, reliable and easy to program. As all of the characters, the effect is obvious in reducing the parking time, and downsizing to improve efficiency.
