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(dāng)務(wù)之急。故障的診斷就是根據(jù)經(jīng)驗(yàn),參照發(fā)生故障的環(huán)境和現(xiàn)象,來(lái)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(dāng)引起的故障。這類故障常見(jiàn)的有供電電源錯(cuò)誤、端子接線錯(cuò)誤、模板安裝錯(cuò)誤、現(xiàn)場(chǎng)操作錯(cuò)誤等。
  2)是否為DCS系統(tǒng)操作錯(cuò)誤引起的故障。這類故障常見(jiàn)的有某整定參數(shù)整定錯(cuò)誤、某設(shè)定狀態(tài)錯(cuò)誤造成的。
  3)確認(rèn)是現(xiàn)場(chǎng)儀表設(shè)備故障還是DCS系統(tǒng)故障。若是現(xiàn)場(chǎng)一次儀表故障,修復(fù)相應(yīng)現(xiàn)場(chǎng)儀表。
  4)若是DCS系統(tǒng)本身的故障,應(yīng)確認(rèn)是硬件毛病或是軟件故障。
  5)若是硬件故障,找出相應(yīng)的硬件部位,更換模板?!?)若是軟件故障,還應(yīng)確認(rèn)是系統(tǒng)軟件或是應(yīng)用軟件故障。
  7)若是系統(tǒng)軟件有故障,可重新啟動(dòng)看能否恢復(fù),或重新裝載系統(tǒng)軟件重新啟動(dòng)。
  8)若是應(yīng)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(cè)試功能,DCS系統(tǒng)的各部分都設(shè)計(jì)有相應(yīng)的自診斷功能,在系統(tǒng)發(fā)生故障時(shí)一定要充分利用這一功能,來(lái)分析和判斷故障的部位和原因。
