模擬量I0自診斷信息
CPU為模擬量模塊和Genius塊的每個通道建立自診斷信息。每個模擬量/O通道的自診斷信息占用一個字節(jié)。每個模擬量1/0通道使用%AI和%AQ占用兩個字節(jié)，所以自
診斷存儲器長度為數(shù)據(jù)存儲器的一半。模擬量自診斷數(shù)據(jù)包括自診斷數(shù)據(jù)和過程數(shù)據(jù)，過程數(shù)據(jù)有高報警和低報警位。自診斷數(shù)據(jù)參考-[F]-和-[NF]-結(jié)點。過程位參考高/低報警結(jié)點，-[HA]- 和-[LA]-。模擬量數(shù)據(jù)的自診斷數(shù)據(jù)為每個模擬量輸入(字)或者模擬量輸出(字)數(shù)據(jù)的自診斷數(shù)據(jù)長度為一個字節(jié)。模擬量故障結(jié)點被應用程序引用時，將對自診斷字節(jié)中除過程位所有位進行或運算。任何一個自診斷位為ON，則報警結(jié)點閉合。所有自診斷位OFF，則報警結(jié)點打開。
冗余模塊的缺省輸入和自診斷數(shù)據(jù)丟失的應用程序
GBC報告冗余模塊丟失時，CPU在下一個輸入掃描更新用缺省數(shù)據(jù)更新輸入數(shù)據(jù)表和自診斷表。在下一次輸出掃描時更新輸出自診斷信息。
