摘　　要：本文以 Control L ogix为例 ,介绍了可编程控制器冗余系统的冗余原理 ,对影响冗余性能的关键问题进行了分析 ,通过减少扫描周期和切换时间来对其冗余性能进行优化 。This article introduces the theory and optimization of redundancy control system based on ControlLogix, and the key problems of the performance are discussed. At the same time, it presented a way to improve the performance of redundancy system via minimizing scan cycle and switchover time, which is useful for users to realize on the similar system.
