· 隨著制造業(yè)競爭的加劇，制造商更加追求生產(chǎn)設(shè)備的可靠性，尤其是那些控制關(guān)鍵性生產(chǎn)工序的設(shè)備，往往需要采用冗余配置。目前，多數(shù)的基于可編程控制器的冗余系統(tǒng)采用了兩套CPU處理器模塊，一個處理器模塊作為主處理器，另外一個作為從處理器。正常情況下，由主處理器執(zhí)行程序，控制I/O設(shè)備，從處理器不斷監(jiān)測主處理器狀態(tài)。如果主處理器出現(xiàn)故障，從處理器立即接管對I/O的控制，繼續(xù)執(zhí)行程序，從而實(shí)現(xiàn)對系統(tǒng)的冗余控制。
很多廠商都能夠提供可編程控制器冗余系統(tǒng)解決方案，用戶在使用過程中往往對其冗余原理理解不深，造成系統(tǒng)冗余性能下降。本文以羅克韋爾自動化Allen Bradley品牌ControlLogix控制器為例，介紹其冗余系統(tǒng)的構(gòu)建和性能優(yōu)化問題。
