• For our ELVIS II units, I'm getting an error-200220. What is the problem with these units when they worked a month ago?

  On several computer stations, we receive the message error-200220 when you select any instrument on the Launcher of the Instrument when you press the run option. This message has not been deleted once the computer has restarted and the power of the bike box. What's wrong?

  I don't find this error code in the product documentation.

  On the screenshot you attached, it seems that there is no devices specified on the front panel, which means that the error you see is correct, the device identifier is invalid.  Are there available devices in control of the aircraft?  Your ELVIS II appears as connected in measurement and Automation Explorer (MAX)?

• Error 200220 CRIO 9081 and data acquisition modules

  Hello

  I try to use a CRIO 9081 with NI9206 modules. Max recognize the chassis, but not the module.

  When I try to add an acquisition of data associated with the NI9206 in Veristand, 200220 error message seems.

  I have the solution, finally he was required to add a custom device to search for new engines and detect modules. Then, it is possible to interact with modules.

  Thank you very much for your help!

• How can you add a device in MAX after getting the error 200220

  Hello

  I get the following error message when I start my datalogging software

  

  When I opened MAX, I noticed that the device NOR I use (USB-TC01) is not listed.

  

  Someone out there would be able to let me know how to add the TC01 device? I know that I need to go to the icon "create new" devices and Interfaces, but do not know how to proceed after that. I get the next screen but not sure what to select.

  

  I use the 9.0.2 version of NOR-DAQmx driver on Windows XP operating system.

  Thanks for your time,

  Kevin

  You may need to update your DAQmx driver.

  Look at this page.  http://sine.NI.com/PSP/app/doc/p/ID/PSP-916/lang/en

  All versions of DAQmx listed are more recent than the 9.0.2 you use.

  Also, take a look at this message thread.  http://forums.NI.com/T5/instrument-control-GPIB-Serial/NI-USB-TC01-not-found/m-p/1454196?requireLogi... which seems to confirm.

• Error-200220 with PCMCIA card 6062E + BNC-2110

  Hi all

  I have a problem with the map 6062E. This is my version of LabVIEW 2010. As is apparent from the attachment, MAX is able to find the device and his name is "Dev17". Also on LabVIEW control channel side found this device and channel a0. What is perhaps my current installation wrong because I get this error all the time?

  I did some tests on the side of MAX and channels measure the voltage in a correct way.

  Thanks in advance,

• County rising edge specifier "10280" generates the error "-200220"»

  Hello

  I use the box USB-6008 with PFI 0 configured as a counter edge.  Everything works fine when I use it to count the edges fall with the "10171" specifier, but .vi DAQmxBase Create Channel (CI-County edges) generates the above error if I simply replaces "10171" with "10280.  This specifier is not recognized by the device?

  Thank you

  Tyler

  Hey Tyler,

  I've dug into this and found an internal report, and apparently only a falling edge can be used as a trigger of edge with patches of meter.  The other problem is that, even if you can use both, there is that a single input pin for this meter and edge only one type can be detected at the time.  The only solution I see would be to try to find a device with several counters, or take an another 6008 and use it to count the edges of the second switch.

• Error with DAQmx 200220

  I try to use a device with NOR-DAQmx, NI USB-6210.  My request is:

  Error-200220 occurred at .vi:1 DAQmx create channel (frequency impulse generation Co)

  Possible reasons:

  Device identifier is invalid.

  Specified device: Dev2

  Task name: _unnamedTask<1>

  How can I fix?

  P.S.:I not know that much with this platform.

  Best regards

  Ana Almeida

  Looks like you are trying to communicate with a device that is named "Dev2.  But LabVIEW is not this device in the system.

  To resolve this issue, open MAX (Measurement and Automation Explorer) from your desktop.  And look at the list of devices.  Its possible that your device somehow got renamed, or maybe its just not being seen for some reason any.  Maybe it is not plugged in correctly!

• USB-6501 - impossible to find a basic example of Labview

  Hello

  I recently bought a USB-6501 card and I used it in my own succesfully end and C++ programs using the DAQmx drivers.

  Then I tried to move to Labview 2009 (I never used Labview) so I looked for a simple example.

  I tried to boot from the example 'interactive Control Panel' (http://digital.ni.com/public.nsf/allkb/AF0F31EE5D2AD23F862573140009D7C2?OpenDocument).

  I had to install the 'DAQmx Base' for him to start, as described in the previous link. now it begins (before Labview attempted to get a few missing .vi) but I get a message "error 200220 occurred at an unidentified locatio.

  Then I realized this example is 'old' (as explained here: http://forums.ni.com/ni/board/message?board.id=170&thread.id=209247), and it is suggested to look for a new one in example Finder ' entry-level equipment / output-> DAQmx-> Digital measurement (or generation)-> read Dig Port.VI.

  I tried, but along the way ' entry-level equipment / output-> DAQmx-> "only a folder named"Analog Measurement\Voltage"exists.

  Also in the search for 'Reading dig Port.VI' does not work.

  I've already spent many hours in this research and tent and the fact that I am not able to find not even a basic example, it is quite frustrating and it is making me give up the idea of using Labview.

  Please can anyone give me any suggestions where find/download an example simple and minimum to use my USB6501 in Labview 2009?

  Thank you

  Scipione.

  First, install DAQmx Base was a mistake. Uninstall it and then install the Driver-OR-DAQmx. The driver must be installed after the installation of LabVIEW. After installation, make sure that the device is listed in MAX under "DAQmx devices. If it is not, your installation is still not correct.

  To search for example LabVIEW, see help > find examples. Under Input and Output hardware > DAQmx, you will find the digital generation and numerical measures. You have to look at the simple, timed software examples such as read write dig Chan, writing Port to dig, dig chan, reading Dig Port. You also have the option to use the DAQ Assistant.

• Operation of USB-6501

  Hi all

  I have a brand new NI USB-6501, and I'm looking for more help with the operation.  I'm running OS X 10.11.1, LabVIEW 2013 SP 1, NI-VISA 15.0 and NOR-DAQmx Base 15.0.0.  I set up and plugged my module and get the flashing green light stable.  I ran NI MAX, found the module and renamed 'Motor_Module '.  Then, I went to my DAQmx Base of examples and found the Control.llb Interactive USB-6501 and ran the interactive VI control that is contained in this library.

  The first thing I tried was simply running the VI.  I got error-200220, device ID is not valid.  I changed the name of the device to "Motor_Module" and run the VI.  This time, I got error-200558, a task cannot contain multiple independent devices.  Create a task for each independent device.

  And here I am.  My ultimate goal is to have this output module signal collector type open to + 5 V.  Any help would be greatly appreciated.  Thank you.

  Hi Sullivnc,

  I would recommend you look at a few examples in the Finder for example of OR. Under input and output hardware, there is a folder for DAQmx who has a record for a digital output which has some useful examples. If you do continuous or left over, you can add more stuff to your code as a clear task DAQmx, vi DAQmx Timing, and/or vi DAQmx task is made.

• DAQmx error: DAQmx Every N samples transferred the event buffer is not d support channel types

  Hello

  Trying to get my new ni9263 below is the steps:

  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
  DAQmxErrChk (DAQmxCreateAOVoltageChan(taskHandle,"Dev1/ao0","",-10,10,DAQmx_Val_Volts,)); NOR-USB 9263
  DAQmxErrChk (DAQmxCfgSampClkTiming (taskHandle,"" SAMPLE_RATE, DAQmx_Val_Rising, DAQmx_Val_ContSamps, SAMPLE_SIZE));

  DAQmxErrChk (DAQmxCfgOutputBuffer (taskHandle, OUTPUT_BUFFER_SIZE));

  DAQmxErrChk (DAQmxRegisterDoneEvent(taskHandle,0,DoneCallback,));

  DAQmxErrChk (DAQmxRegisterEveryNSamplesEvent (taskHandle, DAQmx_Val_Transferred_From_Buffer, EVERY_N_SAMPLES, 0, EveryNSamplesCallbackAO, NULL));
  DAQmxSetWriteRegenMode (taskHandle, DAQmx_Val_DoNotAllowRegen);

  Then I do my writing code and start the task

  When I move my code in my application hangs when it comes to DAQmxRegisterEveryNSamplesEvent with the following error

  DAQmx error: DAQmx Every N samples transferred the event buffer is not d support channel types

  Status code :-200980

  Any idea?

  Greetings;

  When you're talking about an alternative, do you mean a sleeve of spare or chassis or an alternative in the code?

  If it's a matter of code, then you probably need to change your software architecture to adapt the capacity of the installation. In order to avoid to use the FIFO and so have the problem you are experiencing, you avoid needing to register for this event? A few examples on different architectures is on the following link:

• A run-time-error, how to fix

  "I write a function to return a pointer of type float64 and assign the pointer to my defined Pionter 'newdata' in my StartCallBack, there is no error, but when I USE"

  DAQmxWriteAnalogF64 (gtaskhandle0, leng [0])<=leng[1]?2*leng[0]:2*leng[1], 0,="" 10.0,="" daqmx_val_groupbyscannumber,="" newdata,="" &written,="">

  I receive a run-time-error like this: "work.c", line 231, col 121, id thread 0x00007FB4: Array too small argument (40000000 bytes).  Argument must contain at least 80000000 bytes (10000000 items). Why does this happen?

  My part code:

  DAQmxCreateTask ("", & gtaskhandle0 ");
  DAQmxCreateAOVoltageChan (gtaskhandle0, ' Dev1 / ao0:1 ', ' ',-10,0, 10.0, DAQmx_Val_Volts, "");
  DAQmxSetTimingAttribute (gtaskhandle0, DAQmx_SampClk_Rate, 1000/looptime);
  DAQmxCfgSampClkTiming(gtaskhandle0,"",1000/looptime,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,leng[0]+leng[1]);
  DAQmxRegisterDoneEvent(gtaskhandle0,0,DoneCallback,);
  DAQmxWriteAnalogF64 (gtaskhandle0, leng [0])<=leng[1]?2*leng[0]:2*leng[1], 0,="" 10.0,="" daqmx_val_groupbychannel,="" newdata,="" &written,="">
  SetCtrlAttribute (panelHandle, PANEL_REALWRITE, ATTR_CTRL_VAL, (double) written);
  DAQmxStartTask (gtaskhandle0);

  From the code, we cannot see how many samples do you expect to write but there are two aspects to consider.

  DAQmxWriteAnalogF64 expects to receive the number of samples per channel to write; in other words, your "2 *" in the function call is probably wrong. See here for the function. This can cause the error you receive, because the length of the array does not match the settings (you probably want to write 5 million samples per channel).

  Second aspect, it seems to me that your function is the production of the final table with samples interleaved (i.e. array1 [0], array2 [0], array array1 [1], array2 [1]... [n-1] array1, array2 [n-1]). If this is true, you must pass the DAQmx_Val_GroupByScanNumber in the function call.

• Analog output PCI-6251-DAQ-200016 memory overflow error

  NI PCI - 6251 DAQmx, AIMD-752 motherboard, dual core processor, a lot of speed and the ram running WinXP Pro & LabWindows/CVI

  get DAQ-200016 memory overflow error when I try to generate a signal of analog output with a rate higher than about 32 000 samples/second (?)

  going on what?  I have never seen it before.   Is this a problem with the motherboard?    "It's the same product on the CVI code example" \Cont Gen Volt Wfm - Int Clk\ContGen - IntClk.cws.

  If someone has had this problem, and is there a solution?

  Thank you

  PS: full text of the message reads:

  Measurements: On-board memory precision passing. Due to the limitations of system and/or the bandwidth of the bus, the driver could not write data to the device fast enough to track the rate of output of the device.  Reduce your sampling rate, change the method of transfer of data (from interruptions on DMA), use a product with more on-board memory or reduce the number of programs that your computer runs simultaneously. Task name: _unnamedTask<1> Code of State:-200016

  Well, I found my answer.   For later use, Olivia NI Apps Engineering suggested I have change the mechanism of data transfer by this Knowledge Base document:

  http://digital.NI.com/public.nsf/WebSearch/C326F7D33CA6DB0E86256DFE008043B7?OpenDocument

  ... so I inserted the line of code between the creation of the area of OCCUPANCY of the channels and set up the example of clock calendar.

  DAQmxCreateAOVoltageChan( ...
  
  DAQmxSetAODataXferMech(TaskHandle,chan,DAQmx_Val_Interrupts);
  
  DAQmxCfgSampClkTiming(...
  

  now, I am able to generate output to a 2.35 MS/sec... max sampling frequency not quite the 2.86MS / sec indicated in the specification 6251, but close enough that I'll stop complaining

  

• Uninstall software update Apple says error in seller contact package package unstaller

  Try to get itunes working to make a backup of my faulty iphone before repair.

  First-itunes does not start says error. I'm trying to fix it, who said success but same error when you try to start it.

  Then uninstall completely worked. Then reinstall that seemed to be over except for a message "an older version of Apple software update already exists" then he went down and install itunes apparently had not been completed.

  Then I try to remove the update from the apple software and executed by an error in the installation program - it says there is an error in the installation and contact the supplier of the installation package. Same error if I run the uninstall command line program.

  Try to repair the Apple Software Update of programs & features Control Panel and then try to update iTunes again.

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

• An error in this Applescript that I can't understand

  Hi, I searched some forums and found this script below which I modified. It works great except for a single statement:

  runScript If = 1 then number error -128 I want the script to do is, when a USB drive is mounted and is in the ignoredVolumes as "USB Untitled" I want the script to stop. What I can't understand is, runScript is set to 1, "Untitled USB" Monte, runScript is not changed, why don't the script stops with an error "user cancelled"? On the other hand, if a key USB Monte is not in the ignoredVolumes, runScript is set to 2 and copy the file I want it. What hurts? It's probably something that will be very obvious when I see the answer.

  Thanks for any help with this problem,

  The way in which your external block If is currently based, the script can't do anything when this book is in the ignoredVolumes, it can not yet test the runScript value. Try something like this:

  If the present book is in the ignoredVolumes then

  game runScript to 1

  on the other

  if (the present book as text is not '. ') DS_Store') then

  if there are alias (POSIX (' / Volumes / "& the present book) as text file ) then game runScript to 2

  end if

  end if

  
  

  Of course, you need to remove a "end if' the end of the script.
