NI PXI-8461/2接口模块中文资料：

NI PXI-8461/2接口模块如果PLC出现非致命故障，将钥匙开关从OFF转到ON将导致电源上的RUN（运行）灯闪烁5秒。如果在5秒内再次关闭钥匙开关，然后再打开钥匙开关，故障将清除，PLC将进入运行模式（run（运行）灯将保持点亮）。如果PLC出现致命故障，您将无法使用钥匙开关清除故障或将PLC置于运行模式。在恢复操作之前，NI PXI-8461/2您必须纠正故障原因。RAM内存和覆盖保护（可配置）：此功能在CPU固件8.0版中引入。默认情况下，此功能已禁用。除非CPU配置屏幕上的Mem Protect:参数设置为Enabled（启用），否则它不起作用。如果启用此功能且钥匙开关打开，（1）用户RAM内存无法更改（2）离散点无法覆盖，（3）TOD时钟无法使用手持式编程器更改（但是，TOD时钟仍可使用编程软件更改）。NI PXI-8461/2

英文资料

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
