PLC是现代工业的三大支柱之一，是可靠性高、应用非常广泛的工业控制产品。在中大型模块化的PLC产品中，CPU模块（中央处理器）是PLC的中心。一些重大的工业生产线往往要求连续运行不能停顿，而可靠性再高的PLC也不能保证故障为零，因此，双CPU的冗余控制是一种满足连续生产要求、提高系统可用性的有效手段。下面以熔盐炉自控系统为实例详述双CPU冗余控制的实现方法。
一、熔盐炉自动系统综述
熔盐炉自控系统是一水硬铝管道化溶出生产线上的重要环节，控制熔盐的加热和循环，用熔盐的热量去循环加热铝矿石浆。铝矿石浆的加热至关重要，影响最终产品—氧化铝的质量和产量，因此，熔盐的温度控制和循环控制非常重要。
由于熔盐炉系统在管道化工程中的重要性，同时考虑到熔盐是一种活跃的化学品，在不同的温度下有不同的形态，低温下凝固，高温下不稳定会发生化学反应，从而腐蚀管壁甚至于爆炸，所以安全、可靠、操作简便和自动化管理是系统设计的关键，因此考虑用一套双CPU冗余的PLC、两套工控机、高质量的传感器、变送器和执行机构来控制两台1200万大卡的熔盐炉、一台盐泵、一组盐阀、一个熔盐槽和其他相关设备，实现熔盐的加热和循环过程自动化、计算机操作、监控和管理的自动化控制。该系统如图1所示。
