NI PXIE-8840具有動(dòng)態(tài)時(shí)間處理功能

模擬量I0自診斷信息

CPU為模擬量模塊和Genius塊的每個(gè)通道建立自診斷信息。每個(gè)模擬量/O通道的自診斷信息占用一個(gè)字節(jié)。每個(gè)模擬量1/0通道使用%AI和%AQ占用兩個(gè)字節(jié)，所以自

診斷存儲(chǔ)器長(zhǎng)度為數(shù)據(jù)存儲(chǔ)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(guò)程數(shù)據(jù)，過(guò)程數(shù)據(jù)有高報(bào)警和低報(bào)警位。自診斷數(shù)據(jù)參考-[F]-和-[NF]-結(jié)點(diǎn)。過(guò)程位參考高/低報(bào)警結(jié)點(diǎn)，-[HA]- 和-[LA]-。模擬量數(shù)據(jù)的自診斷數(shù)據(jù)為每個(gè)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(zhǎng)度為一個(gè)字節(jié)。模擬量故障結(jié)點(diǎn)被應(yīng)用程序引用時(shí)，將對(duì)自診斷字節(jié)中除過(guò)程位所有位進(jìn)行或運(yùn)算。任何一個(gè)自診斷位為ON，則報(bào)警結(jié)點(diǎn)閉合。所有自診斷位OFF，則報(bào)警結(jié)點(diǎn)打開(kāi)。

冗余模塊的缺省輸入和自診斷數(shù)據(jù)丟失的應(yīng)用程序

GBC報(bào)告冗余模塊丟失時(shí)，CPU在下一個(gè)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(shí)更新輸出自診斷信息。
