PLC是現(xiàn)代工業(yè)的三大支柱之一,是可靠性高、應(yīng)用非常廣泛的工業(yè)控制產(chǎn)品。在中大型模塊化的PLC產(chǎn)品中,CPU模塊(中央處理器)是PLC的中心。一些重大的工業(yè)生產(chǎn)線往往要求連續(xù)運(yùn)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(xù)生產(chǎn)要求、提高系統(tǒng)可用性的有效手段。下面以熔鹽爐自控系統(tǒng)為實(shí)例詳述雙CPU冗余控制的實(shí)現(xiàn)方法。
在所有指令執(zhí)行完畢后,將各物理繼電器對(duì)應(yīng)的輸出狀態(tài)寄存器的通 / 斷狀態(tài),在輸出刷新階段轉(zhuǎn)存到輸出寄存器,去控制各物理繼電器的通 / 斷,這才是 PLC 的實(shí)際輸出。用接觸器對(duì)變壓器進(jìn)行控制時(shí),應(yīng)考慮浪涌電流的大小。例如交流電弧焊機(jī)、電阻焊機(jī)等,一般可按變壓器額定電流的2倍選取接觸器,型號(hào)選CJl0、CJ20等。
