PLC控制器是系統(tǒng)控制的中心，采集系統(tǒng)的全部工況信號，實(shí)時控制相關(guān)的設(shè)備動作；同時監(jiān)視生產(chǎn)過程參數(shù)和設(shè)備運(yùn)行狀態(tài)，當(dāng)危險工況出現(xiàn)時，及時發(fā)出聲光報(bào)警，當(dāng)極限工況出現(xiàn)時，聯(lián)鎖保護(hù)設(shè)備，保障生產(chǎn)過程安全。為此，我們選擇了以產(chǎn)品可靠性高著稱的羅克韋爾自動化公司的新一代控制平臺：A-B ControlLogix系列，同時考慮采用雙CPU模塊冗余，進(jìn)一步提高系統(tǒng)可靠性，避免因故障出現(xiàn)所引起的生產(chǎn)停頓或安全事故。

塊CPU同時在線運(yùn)行，一塊處于主控制模式，另一塊處于熱備模式。擁有主控制權(quán)的CPU具有輸出控制權(quán)，而熱備CPU同時采集數(shù)據(jù)和保持通訊連接，但輸出被禁止。

兩個CPU模塊互相監(jiān)視對方的運(yùn)行狀態(tài)和通訊情況，一旦發(fā)現(xiàn)對方故障，立即發(fā)出報(bào)警，通過ControlNet網(wǎng)，傳送給上位工控機(jī)，在操作管理臺上顯示報(bào)警。如果是主控CPU模塊故障，熱備CPU模塊自動獲得主控制權(quán)。
