什么是PLC冗余系统 PLC 冗余可以分为:软件冗余和硬件冗余。硬件冗余对硬件型号有所要求,连接方式也不同,但对软件并无特殊要求。 在工业自动化系统中大量选用可编程逻辑控制器(PLC)作为控制器,随着技术的发展又组建冗余系统进一步提高系统的可靠性。目前冗余的分类方式很多,而采用PLC冗余方式的有两种,即软冗余和硬亢余。西门子公司在软、硬冗余两方面均给出了解决方案。而基于硬冗余的可靠性高,但构建系统成本也较高。而基于S7—300或S7—400的软冗余是一种成本低又能提高可靠性的方案。目前,软冗余系统已经在冶金、交通、电力、化工、污水处理等工业控制工程中得到了较广泛的应用。但是对于软冗余的性能仍没有进行系统的研究。 什么是硬冗余?需要什么配置要求?   硬冗余系统的冗余结构确保了任何时候的系统可靠性,例如所有的重要部件都是冗余配置。这包括了冗余的CPU、供电模件和用于冗余CPU通信的同步模块。根据特定的自动化控制过程需要,还可以配置冗余客户服务器、冗余通讯介质、冗余接口模件IM153-2等。   硬冗余系统能够:   1. 平滑的主从切换   2. 自动事件同步   3. 集成的错误识别和错误定位功能   4. 操作期间可对系统进行修改   5. 类似标准CPU的在线编程   6. 下载程序时,只考虑单个CPU,程序可自动拷贝到另一个CPU中。   7. CPU修复后自动再进入。   8. 运行中所有部件可更换。 软冗余实现原理: 系统运行过程中两个CPU同时启动和运行,但是在正常运行时只有主CPU发出控制命令,而备用CPU检测主CPU状态和记录主CPU发出的命令,当主CPU发生故障时能够延续当时的实际状态接替主CPU发出执行命令。与主CPU通信的IM153—2模块处于激活状态时主CPU能访问I/0模块。当系统发生特定故障时,系统可以实现主备切换,备站接替主站继续运行。 。
