描述
DCS系統(tǒng)本身在工作中不斷地進行在線故障檢測,一旦發(fā)現(xiàn)故障,就將故障設備與系統(tǒng)隔離,使它不至于影響其他設備的正常運行。故障出現(xiàn)后同時會發(fā)出聲光報警,維護人員根據(jù)報警的提示進行分析故障原因并盡快的處理故障,避免故障擴大。在處理過程中要做好現(xiàn)場的技術措施,不要輕易重啟CPU,以免對設備造成擾動。如果需要重啟CPU,需要與操作人員配合做好預防措施,一般DCS在CPU復位時會對模擬量輸出信號進行復位,這樣可以對執(zhí)行器和變頻器采用手動切換控制方式,執(zhí)行器也可以采用斷電方式或將模擬量輸出卡件拔掉方式(執(zhí)行器具有斷信號保持功能),系統(tǒng)正常后將信號加到正常值后再給執(zhí)行器上電和插卡件。但是一定要根據(jù)DCS本身的特點進行,有的設計中有開關量安全輸出(開、關、保持等),如果用戶在組態(tài)時選的安全輸出是開,那當重啟CPU后開關量會發(fā)出開的指令。
