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。
大型、重型設(shè)備的主運(yùn)動(dòng)和進(jìn)給運(yùn)動(dòng),應(yīng)盡可能采用無級(jí)調(diào)速,有利于簡(jiǎn)化機(jī)械結(jié)構(gòu)、降低成本;精密機(jī)械設(shè)備為保證加工精度也應(yīng)采用無級(jí)調(diào)速;對(duì)于一般中小型設(shè)備,在沒有特殊要求時(shí),可選用經(jīng)濟(jì)、簡(jiǎn)單、可靠的三相籠型異步電動(dòng)機(jī)對(duì)PLC本體按照規(guī)定的標(biāo)準(zhǔn)和接地條件進(jìn)行接地。
