zui近出廠的DCS采用通用操作站，它采用NT操作系統(tǒng)控制工程網(wǎng)版權(quán)所有，監(jiān)控軟件就是FIX、INTOUCH.不同DCS型號(hào)采用不同的驅(qū)動(dòng)軟件。各種DCS之間信號(hào)傳輸采用OPC服務(wù)器聯(lián)接，也可以把少量的信號(hào)送到MIS系統(tǒng)的服務(wù)器中。FIX、INTOUCH等軟件都能存儲(chǔ)歷史數(shù)據(jù)，幾十個(gè)信號(hào)可存儲(chǔ)280天之多。如要存儲(chǔ)更多的歷史數(shù)據(jù)，可以采用OSI歷史數(shù)據(jù)庫(kù)，它可以存儲(chǔ)三年以上。這些通用監(jiān)控軟件都有OSI的接口。老一代的DCS系統(tǒng)的操作站無(wú)論操作系統(tǒng)還是監(jiān)控軟件都是的，和其它系統(tǒng)通訊都非常困難。

硬件故障改如何檢查？
硬件故障常常表現(xiàn)為以下幾方面
            ！ 模塊的插件板與總線底板插接不嚴(yán)密；
            ！ 撥碼開(kāi)關(guān)錯(cuò)誤；通訊線接線方向錯(cuò)誤；
            ！ 終端匹配器未接；
            ！ 硬件跳線與實(shí)際信號(hào)要求的類(lèi)型不*；
            ！ 機(jī)柜內(nèi)系統(tǒng)電源、現(xiàn)場(chǎng)電源輸出有誤；
            ！ 硬件本身壞。

            以上幾方面問(wèn)題的結(jié)果表現(xiàn)為：
            ！ 加電后硬件板極故障（指示燈顯示狀態(tài)不對(duì)）；
            ！ 設(shè)備不工作；
            ！ 系統(tǒng)工作但顯示的對(duì)應(yīng)測(cè)點(diǎn)值不正確、系統(tǒng)的輸出不能驅(qū)動(dòng)現(xiàn)場(chǎng)設(shè)備等等。
