Rexroth R978919725合理地配置可編程序控制器系統(tǒng)的冗余可編程序控制系統(tǒng)可能做出多種方式的冗余，中央處理器的雙機(jī)熱備、冷備冗余是常見(jiàn)的方式。另外，雙系統(tǒng)冗余，即中央處理器和全部的輸入、輸出、組網(wǎng)通信完全冗余，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。 以上闡述的幾個(gè)方面，是在可編程序控制系統(tǒng)總體方案設(shè)計(jì)時(shí)，要格外重視的問(wèn)題，只有在設(shè)計(jì)系統(tǒng)時(shí)，考慮周到，系統(tǒng)投入運(yùn)行之后，設(shè)計(jì)人員才能少些遺憾。
