NI PXI-8461/2接口模塊中文資料：

NI PXI-8461/2接口模塊如果PLC出現(xiàn)非致命故障，將鑰匙開關(guān)從OFF轉(zhuǎn)到ON將導(dǎo)致電源上的RUN（運行）燈閃爍5秒。如果在5秒內(nèi)再次關(guān)閉鑰匙開關(guān)，然后再打開鑰匙開關(guān)，故障將清除，PLC將進入運行模式（run（運行）燈將保持點亮）。如果PLC出現(xiàn)致命故障，您將無法使用鑰匙開關(guān)清除故障或?qū)LC置于運行模式。在恢復(fù)操作之前，NI PXI-8461/2您必須糾正故障原因。RAM內(nèi)存和覆蓋保護（可配置）：此功能在CPU固件8.0版中引入。默認情況下，此功能已禁用。除非CPU配置屏幕上的Mem Protect:參數(shù)設(shè)置為Enabled（啟用），否則它不起作用。如果啟用此功能且鑰匙開關(guān)打開，（1）用戶RAM內(nèi)存無法更改（2）離散點無法覆蓋，（3）TOD時鐘無法使用手持式編程器更改（但是，TOD時鐘仍可使用編程軟件更改）。NI PXI-8461/2

英文資料

If the PLC has a non-fatal fault, turning the key switch from OFF to ON will cause the RUN light on the power supply to flash for 5 seconds. If you again turn the key switch OFF, then ON during the 5 seconds, the fault will clear and the PLC will go into run mode (ａnd the RUN light will stay ON). If the PLC has a fatal fault, you will not be able to use the keyswitch to either clear the fault or put the PLC into run mode. You will have to correct the cause of the fault before being able to resume operation.RAM Memory and Override Protection (configurable): This feature was introduced in CPU firmware release 8.0. This feature is, by default, disabled. It is not functional unless the Mem Protect: parameter on the CPU configuration screen is set to Enabled. If this feature is enabled and the keyswitch is ON, (1) user RAM memory cannot be changed (2) discrete points cannot be overridden, and (3) the TOD clock cannot be changed with the Hａnd Held Programmer (however, the TOD clock can still be changed using programming software).NI PXI-8461/2
