 PLC是現代工業的三大支柱之一，是可靠性高、應用非常廣泛的工業控制產品。在中大型模塊化的PLC產品中，CPU模塊（中央處理器）是PLC的中心。一些重大的工業生產線往往要求連續運行不能停頓，而可靠性再高的PLC也不能保證故障為零，因此，雙CPU的冗余控制是一種滿足連續生產要求、提高系統可用性的有效手段。下面以熔鹽爐自控系統為實例詳述雙CPU冗余控制的實現方法。
一、熔鹽爐自動系統綜述
熔鹽爐自控系統是一水硬鋁管道化溶出生產線上的重要環節，控制熔鹽的加熱和循環，用熔鹽的熱量去循環加熱鋁礦石漿。鋁礦石漿的加熱至關重要，影響*終產品—氧化鋁的質量和產量，因此，熔鹽的溫度控制和循環控制非常重要。
由于熔鹽爐系統在管道化工程中的重要性，同時考慮到熔鹽是一種活躍的化學品，在不同的溫度下有不同的形態，低溫下凝固，高溫下不穩定會發生化學反應，從而腐蝕管壁甚至于爆炸，所以安全、可靠、操作簡便和自動化管理是系統設計的關鍵，因此考慮用一套雙CPU冗余的PLC、兩套工控機、高質量的傳感器、變送器和執行機構來控制兩臺1200萬大卡的熔鹽爐、一臺鹽泵、一組鹽閥、一個熔鹽槽和其他相關設備，實現熔鹽的加熱和循環過程自動化、計算機操作、監控和管理的自動化控制。
