可編程序控制系統(tǒng)可能做出多種方式的冗余,*處理器的雙機(jī)熱備、冷備冗余是常見(jiàn)的方式。另外,雙系統(tǒng)冗余,即*處理器和全部的輸入、輸出、組網(wǎng)通信*冗余,其價(jià)格和實(shí)用性雖然在許多工程項(xiàng)目中難以被人接受,但在有毒、有害的化工生產(chǎn)環(huán)境這種冗余很有必要。在設(shè)計(jì)系統(tǒng)中,要使配置冗余方式較為經(jīng)濟(jì)而又實(shí)用,力求使故障縮小在本設(shè)備身上。不要因某一設(shè)備發(fā)生故障,引起工藝流程中相關(guān)設(shè)備運(yùn)行或狀態(tài)受到?jīng)_擊。
