·                                  随着制造业竞争的加剧，制造商更加追求生产设备的可靠性，尤其是那些控制关键性生产工序的设备，往往需要采用冗余配置。目前，多数的基于可编程控制器的冗余系统采用了两套CPU处理器模块，一个处理器模块作为主处理器，另外一个作为从处理器。正常情况下，由主处理器执行程序，控制I/O设备，从处理器不断监测主处理器状态。如果主处理器出现故障，从处理器立即接管对I/O的控制，继续执行程序，从而实现对系统的冗余控制。
 很多厂商都能够提供可编程控制器冗余系统解决方案，用户在使用过程中往往对其冗余原理理解不深，造成系统冗余性能下降。本文以罗克韦尔自动化Allen Bradley品牌ControlLogix控制器为例，介绍其冗余系统的构建和性能优化问题。
