對(duì)DCS系統(tǒng)維護(hù)總結(jié)以下幾點(diǎn)：

　　(1) 定期對(duì)DCS系統(tǒng)電源進(jìn)行檢查，對(duì)于冗余電源系統(tǒng)要定期進(jìn)行切換實(shí)驗(yàn)工作。同時(shí)對(duì)UPS電源進(jìn)行定期的切換檢查，對(duì)電池按照要求進(jìn)行定期放電充電。

　　(2) 定期檢查網(wǎng)絡(luò)接頭和各連接線是否牢固，控制柜內(nèi)的各接線端子是否牢固可靠。

　　(3) 經(jīng)常檢查控制單元、I/O模塊、其他模塊等的工作是否正常。

　　(4) 定期檢查接地是否牢固，測(cè)試接地電阻是否符合要求。

　　(5) 定期檢查控制器、計(jì)算機(jī)等的工作負(fù)荷，并注意是否有升高現(xiàn)象。

　　(6) 定期檢查MMI硬盤(pán)，并刪除零碎文件，歷史文件經(jīng)常進(jìn)行外設(shè)歸檔備份。

　　(7) 利用機(jī)組檢修期間逐個(gè)復(fù)位DCS系統(tǒng)的DPU(分散處理單元)和MMI(人機(jī)接口)，以消除計(jì)算機(jī)*運(yùn)行的累計(jì)錯(cuò)誤。
