DCS系統(tǒng)在工業(yè)生產(chǎn)過程的廣泛應(yīng)用，使可靠性、穩(wěn)定性問題更加突出，也使人們對(duì)整個(gè)系統(tǒng)要求越來越高。人們希望DCS系統(tǒng)盡量少出故障，又希望DCS系統(tǒng)一旦出現(xiàn)故障，能盡快診斷出故障部位，并盡快修復(fù)，使系統(tǒng)重新工作。下面簡(jiǎn)單介紹故障大體分類及故障診斷的一般方法。
　　一、DCS系統(tǒng)故障的分類
　　為了便于分析、診斷DCS系統(tǒng)故障發(fā)生的部位和產(chǎn)生原因，可以把故障大致分為如下幾類。
　　1、現(xiàn)場(chǎng)儀表設(shè)備故障
　　現(xiàn)場(chǎng)儀表設(shè)備包括與生產(chǎn)過程直接聯(lián)系的各種變送器、各種開關(guān)、執(zhí)行機(jī)構(gòu)、負(fù)載等?，F(xiàn)場(chǎng)儀表設(shè)備發(fā)生故障，直接影響DCS系統(tǒng)的控制功能。在目前的DCS控制系統(tǒng)中，這類故障占絕大部分。這類故障一般是由于儀表設(shè)備本身的質(zhì)量和壽命所致。
　　2、系統(tǒng)故障
　　這是影響系統(tǒng)運(yùn)行的全局性故障。系統(tǒng)故障可分為固定性故障和偶然性故障。這類故障一般比較明顯且影響也是局部的，它們主要是由使用不當(dāng)或使用時(shí)間較長(zhǎng)，模板內(nèi)元件老化所致。
　　3、硬件故障
　　這類故障主要指DCS系統(tǒng)中的模板(特別是I/O模板)損壞造成的故障。這類故障一般比較明顯且影響也是局部的，它們主要是由使用不當(dāng)或使用時(shí)間較長(zhǎng)，模板內(nèi)元件老化所致。
　　4、軟件故障
　　這類故障是軟件本身所包含的錯(cuò)誤所引起的，軟件故障又可分為系統(tǒng)軟件故障和應(yīng)用軟件故障。系統(tǒng)軟件是DCS系統(tǒng)帶來的，若設(shè)計(jì)考慮不周，在執(zhí)行中一旦條件滿足就會(huì)引發(fā)故障，造成停機(jī)或死機(jī)等現(xiàn)象。此類故障并不常見。應(yīng)用軟件是用戶自己編定的。在實(shí)際工程應(yīng)用中，由于應(yīng)用軟件工作復(fù)雜，工作量大，因此軟件錯(cuò)誤幾乎難以避免，這就要求在DCS系統(tǒng)調(diào)試及試運(yùn)行中十分認(rèn)真，及時(shí)發(fā)現(xiàn)并解決。
　　5、操作、使用不當(dāng)造成故障
　　在實(shí)際運(yùn)行操作中，有時(shí)會(huì)出現(xiàn)DCS系統(tǒng)某功能不能使用或某控制不封不能正常工作，但實(shí)際上DCS系統(tǒng)并沒有毛病，而是操作人員操作不熟練或操作錯(cuò)誤所引起的。這對(duì)于初次使用DCS系統(tǒng)的操作工較為常見。
