為了保證互為冗余的兩個(gè)卡件具有平等獲取外部信息(I/O通訊、網(wǎng)絡(luò)通訊)的權(quán)利,冗余部件具有同樣的通訊接口,保證卡件內(nèi)輸入信息的一致。冗余的兩塊卡件有各自的通訊通路,只要保證相同的輸入信息在兩個(gè)通信通路上同時(shí)進(jìn)行傳輸,兩塊卡件就可以獲得相同的信息。這種憑借外部設(shè)備實(shí)現(xiàn)輸入信息的同步稱為“自然同步”?!白匀煌健卑l(fā)生在冗余系統(tǒng)和外部設(shè)備之間。工作卡掌握主動(dòng)權(quán),代表整體發(fā)言,并通過(guò)冗余通信將各種狀態(tài)信息傳送給備用卡,達(dá)到控制任務(wù)的同步,這就是“強(qiáng)制同步”?!皬?qiáng)制同步”通過(guò)冗余通信使備用卡內(nèi)部控制狀態(tài)與工作卡保持一致,它發(fā)生在互為冗余的卡件之間。根據(jù)變量特性的不同,具體采用的同步方式也各不相同.
