VxWorks Targets Do Not Honor New Daylight Savings Time Rules Recently, the rules for Daylight Savings Time start and stop have changed. My VxWorks-based controller (such as the cRIO 901x series) seems to be an hour off sometimes. How do I correct this? URL: http://digital.ni.com/public.nsf/allkb/7E5CB910B1685C8B8625731A005FCB62

LabVIEW Runtime error in MAX when accessing a cRIO-901x with LabVIEW Real-Time 8.5 from MAX 4.2.1 or earlier When attempting to expand the Software tab in MAX on a cRIO-901x I get several error message for my controllers that have LabVIEW Real-Time 8.5 installed. One of these error messages indicates an error starting the LabVIEW Runtime and says to reinstall your product and then contact National URL: http://digital.ni.com/public.nsf/allkb/1584D952E54ABB59862572F7006F3438

当我在MAX 4.2.1或更早版本上使用装有LabVIEW Real-Time 8.5的cRIO-901x时，出现LabVIEW Runtime error 在我的安装了LabVIEW Real-Time 8.5的控制器上，当我在MAX中对cRIO-901x展开Software tab时，遇到了一些错误信息。其中的一条错误信息指出了启动LabVIEW Runtime的错误，并且提示重装该产品并且联系National Instruments.当我从该控制器上安装/卸载软件时，另一条消息对话框提示该 URL: http://digital.ni.com/public.nsf/allkb/119A978A104B95DC862573570044166F

为什么 CompactRIO 控制器上的状态灯在启动阶段没有亮？ 启动我的 CompactRIO（cRIO）控制器时状态灯没有亮，控制器花了几分钟时间才启动。我看了手册，手册指出状态 LED 应该在启动阶段变亮。 控制器是全新的，不像是硬件错误。我还能检查什么吗？ URL: http://digital.ni.com/public.nsf/allkb/7993EDD4307C4E9E4825721F001DF11C

Startup EXE not Launching on Real-Time (RT) Target at Controller Reset I have a real-time system with a startup EXE embedded on the controller. However, the EXE only launches when the controller is connected to the ethernet/network cable. Whenever the ethernet cable is removed, the startup EXE does not launch on controller reset.

CompactRIO 컨트롤러가 부팅하는 동안 Status LED가 왜 들어오지 않습니까? CompactRIO(cRIO) 컨트롤러가 부팅하는 동안 Status LED가 들어오지 않고 컨트롤러는 부팅하는데 오랜시간이 걸린다(몇 분정도). 메뉴얼을 보면 Status LED가 부팅하는 동안에는 켜져야 한다고 나와있습니다. 컨트롤러가 새로나온 제품이므로 하드웨어적인 에러를 URL: http://digital.ni.com/public.nsf/allkb/4EE9D76FB10DBBFF8625721100060C49

Why Isn't the CompactRIO Controller Status Light Lit During Boot-up? While my CompactRIO (cRIO) Controller boots, the Status light does not light up and the controller takes several minutes to boot up. I have looked in the manual, and it indicates that the Status LED should turn on for a period of time during boot-up. The controller is brand new, and URL: http://digital.ni.com/public.nsf/allkb/CF39B23ED3E3C06E862571FB007DC1CF

Actual Excitation Voltage of NI 9237 Differs from Specified Voltage When creating a DAQmx Task for Strain or Custom Voltage with Excitation with the NI 9237, the excitation voltage that I specified in the task is not the same as I measure across Ex+ and Ex-. For example, URL: http://digital.ni.com/public.nsf/allkb/5CA74236A6A1919B862571D5005A41D0

NI 9237實際的激發電壓(Excitation Voltage)與指定的電壓不同 當使用 NI 9237 建立 Strain 或 Custom Voltage with Excitation 的 DAQmx Task 時，我所指定的激發電壓與我直接去量測 Ex+ 與 Ex- 的電壓值不同。舉例來說，若我指定激發電壓為 6V，而我所量測到在 Ex+ 與 Ex- 的壓差只有5 V。為什麼實際的激發電壓與指定的電壓 URL: http://digital.ni.com/public.nsf/allkb/D92F7641B906E9328625737D001BC48F

Noisy DC Power Can Cause Unpredictable CompactRIO Operation My CompactRIO System is behaving in an unexpected manner. Sometimes it reboots randomly or even fails to boot at all. It is powered off a vehicle's power supply. What is happening? URL: http://digital.ni.com/public.nsf/allkb/75B55124050702C68625718E0049013D
