DCS系統(tǒng)故障診斷步驟
　　DCS系統(tǒng)一旦出現(xiàn)故障，正確分析和診斷故障發(fā)生的部位是當務之急。故障的診斷就是根據(jù)經(jīng)驗，參照發(fā)生故障的環(huán)境和現(xiàn)象，來確定故障的部位和原因。這種診斷方法因DCS系統(tǒng)產(chǎn)品不同而有一定差別。
　　1)是否為使用不當引起的故障。這類故障常見的有供電電源錯誤、端子接線錯誤、模板安裝錯誤、現(xiàn)場操作錯誤等。
　　2)是否為DCS系統(tǒng)操作錯誤引起的故障。這類故障常見的有某整定參數(shù)整定錯誤、某設定狀態(tài)錯誤造成的。
　　3)確認是現(xiàn)場儀表設備故障還是DCS系統(tǒng)故障。若是現(xiàn)場一次儀表故障，修復相應現(xiàn)場儀表。
　　4)若是DCS系統(tǒng)本身的故障，應確認是硬件毛病或是軟件故障。
　　5)若是硬件故障，找出相應的硬件部位，更換模板?！?)若是軟件故障，還應確認是系統(tǒng)軟件或是應用軟件故障。
　　7)若是系統(tǒng)軟件有故障，可重新啟動看能否恢復，或重新裝載系統(tǒng)軟件重新啟動。
　　8)若是應用軟件故障，可檢查用戶編寫的程序和組態(tài)的所有數(shù)據(jù)，找出故障原因。
　　9)利用DCS系統(tǒng)的自診斷測試功能，DCS系統(tǒng)的各部分都設計有相應的自診斷功能，在系統(tǒng)發(fā)生故障時一定要充分利用這一功能，來分析和判斷故障的部位和原因。
