NI PXI-5402波形信號函數(shù)發(fā)生器這些故障表不會報(bào)告有缺陷的限位開關(guān)等情況，但會識別系統(tǒng)故障，例如：?模塊丟失或缺失、系統(tǒng)配置不匹配。?CPU硬件故障、低電量?PLC軟件故障、程序校驗(yàn)和故障、無用戶程序、PLC存儲故障。系統(tǒng)狀態(tài)參考這些離散參考（%S、%SA、%SB和%SC）可以在系統(tǒng)參考（狀態(tài)）表中查看，NI PXI-5402如果在梯形圖程序中使用，則可以在屏幕上查看，以確定各種條件和故障的狀態(tài)。例如，如果任一故障表中記錄了故障，則%SC0009位將打開。另一個例子是，如果CPU內(nèi)存?zhèn)溆秒姵仉娏坎蛔悖?strong style="white-space: normal;">NI PXI-5402將打開。Series 90-30 PLC CPU指令集參考手冊GFK-0467包括“系統(tǒng)狀態(tài)參考表”。參考表有兩種類型的參考表，標(biāo)準(zhǔn)和混合。這些表顯示內(nèi)存地址組及其狀態(tài)。對于離散地址，這些地址的狀態(tài)將顯示為邏輯1或邏輯0。對于模擬和寄存器地址，將顯示值。NI PXI-5402
hese fault tables will not report such things as a defective limit switch, but will identify system faults such as: ? Loss of or Missing Modules, System Configuration Mismatch. ? CPU hardware failure, Low Battery ? PLC Software Failure, Program Checksum Failure, No User Program, PLC Store Failures. System Status References These discrete references NI PXI-5402can be viewed in the System Reference (Status) Table, or on-screen if used in the ladder program, for determining the status of various conditions and faults. For example, the %SC0009 bit turns on if a fault is logged in either fault table. Another example is that bitNI PXI-5402 will turn on if the CPU memory backup battery is low. The Series 90-30 PLC CPU Instruction Set Reference Manual, GFK-0467, includes a “System Status Reference Table.”Reference Tables There are two types of reference tables, standard and mixed. These tables show groups of memory addresses and their status. For discrete addresses, the status of these will be shown as either logic 1 or logic 0. For analog and register addresses, values will be displayed.NI PXI-5402
