機(jī)組檢修期間應(yīng)對(duì)DCS 系統(tǒng)應(yīng)進(jìn)行徹底的維護(hù),主要包括:
( 1)利用機(jī)組檢修時(shí)間逐個(gè)復(fù)位DCS系統(tǒng)的DPU、CPU和操作員站及數(shù)據(jù)站;刪除組態(tài)中的無(wú)效I/O點(diǎn),對(duì)組態(tài)進(jìn)行優(yōu)化。
(2)系統(tǒng)冗余測(cè)試: 對(duì)冗余電源、服務(wù)器、控制器、通訊網(wǎng)絡(luò)進(jìn)行冗余測(cè)試。注意系統(tǒng)各設(shè)備停電時(shí),主從設(shè)備切換、網(wǎng)絡(luò)、人機(jī)接口站是否正常;系統(tǒng)檢修重新上電后對(duì)各設(shè)備進(jìn)行切換測(cè)試。
