| 摘 要： | 可编程序控制器(ProgrammableLogicController,PLC)的双CPU冗余运行对于工业自动化控制系统的可靠性有着重要意义。针对传统基于硬件策略的双CPU的PLC冗余控制方式存在的问题,提出了基于软件策略的双CPU冗余控制思想,并详细描述了利用A-BControlLogix系列PLC实现双CPU冗余软件设计的具体方案。

| Abstract: | CPU redundancy control has important meanings for reliability in the automated industry control system based on PLC (Programmable Logic Controller). According to the insufficiencies of traditional CPU redundancy control based on hardware completely, the design idea of CPU redundancy control based on software is put forward. And the scheme utilizing A-B ControlLogix PLC to realize it is described concretely in detail. |
