• Error-200257 with DAQmx

  Hey all -

  We are using an architecture of producer-consumer to read data from the strain of two cells using a NI 9237 module and then write the data of deformation in a file when a simulated square wave exceeds a certain threshold value (this is supposed to simulate a digital triggering).  I get code error-200257 when I run the program. I tried this error code of online research and forums and have tried to manually increase the size of the buffer by adding in the entry Buffer.vi set up.  I also tried increasing and decreasing the sample rate and increasing by reducing the number of samples read by channel.  However, if the program is allowed to run for a minute or two, it ends by stops and gives the code of-200257 error.

  I have attached my program below.  Any other suggestions as to what I might try next would be greatly appreciated!

  Thank you!

  Why are you writing to the file of measure in two loops? That could cause an error bound to the buffer but this code does not refer to the size of the buffer.

• With a sampling of the data with DAQMX, error-200279 occurs when making 2d array dbl

  Hello

  I did a system of simple analog voltage with DAQMX data acquisition.

  It is made for reading of capacitance, where output capacitance value out of a circuit in the periodic voltage signal.

  What I want is to get data from four capacitors simultaneously through four channels, using samples n n (dbl 2d).

  The structure of my VI is almost similar with examples of continuous sampling of voltage in LabView, with the exception of a few other calculations in the loop.

  And for the synchronization of the trigger, I've corrected the edge of release with the external signal from the capacitance reading circuit.

  Version no. 1 has a channel for data input voltage. Version n ° 2 has four channels for the input data.

  While ver.1 can get accurate reading of four capacitors circuit data each (a single channel at a time),.

  ver.2 acquires four channels of data, with a single thin data channel, all the others were wrong.

  I saw a 200279 error occur in the DAQMX read part 2d dbl, so I tried increasing the buffers by changing the sampling frequency or the number of samples, but it wasn't everything.

  I rose for most of the forums with the 200279 error, but the solution would not work on mine.

  Anyone can find the problem? I will attach my screws it may include a bit of Korean language, but most of them are in English, shouldn't be too hard to recognize. Sorry for the inconvenience.

  Oh I forgot, my DAQ is NI USB-6259, and it works in Win XP sp3 and LabView 8.6.

  Thank you.

  Hello Azurenight,

  The 6259 is a DAQ card of the M Series Multiplexed, which means that it is not possible to sample each signal at the same instant, rather the channels are all sent through the ADC even and must be sampled in order. More information on this can be found here:

  LabVIEW Help: Multiplexing compared with simultaneous sampling

  http://zone.NI.com/reference/en-XX/help/370466W-01/mxcncpts/multisimulsamp/

  It may still be possible to get the data you need with the card you have - could you give more information about the maximum eligible period between samples on different channels?

  If you require * real * simultaneous sampling, you will probably need different hardware.

  Kind regards

• Stand-alone application with LabView 7.0 get error cannot find DAQmx clear task.vi

  I tried to create a stand alone vi with the Build Application or shared Library (dll) in LabVeiw 7.0

  When I put it on another PC to test it I get the error "cannot find DAQmx clear task.vi.

  the other PC also has 7.0 and 8.1 DAQmx Labview.

  I think my problem is in the source tab, where you are supposed to add dynamic vi and support, I have search the forums and database of nor and have not found a solution.

  Hi LabTech09,

  When you run the executable file on the other computer, that's when you get this error?  You have the same exact versions of DAQmx and LabVIEW on both computers?  Is the dialog box allow you to navigate to the clear task.vi DAQmx?  If so, you can find these screws in C:\Program NIUninstaller Instruments\LabVIEW 7.0\vi.lib\DAQmx\configure\task.llb.  The executable runs on the development computer (the machine, it was compiled on)?

  P.S. Full Error Message is "error-200284 occurred at dataacq_simpleexample.vi.» Possible reasons: some or all of the requested samples are not yet acquired. To wait for samples become available longer read timeout or read further in your program. To make samples available more quickly, increase the frequency of sampling. If your task uses a trigger to start, make sure that your startup trigger is configured correctly. It is also possible that you have configured the external sync task, and no clock has been provided. If this is the case, provide an external clock. »

  P.P.S.

  The 10s 'limit' request that the number of channels collected either 1 or 2. Also, the limit applies if the data are collected as "Unscaled" (U16) or scaled (DBL).

  Adding a sequence structure contianing a waiting and runs the task and data signals arrray lines through the sequence with the expectation, with wait times = given expected time CQI, has not fixed the problem.

  It indicates that you have a time-out error.

  Put running context-sensitive help and hover over the DAQmx playback function.  You see that there is a timeout of entry.  The default value is 10 seconds, which you can discover by clicking right on the terminal timeout and picking create constant, or by opening detailed to the top and read on the DAQmx playback function.

  As you collect 250 samples at a rate of 20, which takes 12.5 seconds, so longer than the default timeout period.

• PXI-6133 Pulse frequency output and input with DAQmx

  I am trying to set a pulse meter output frequency task and read this signal with a frequency counter input task input pulses.  I use a 2 PXI-6133, each connected to a BNC-2090 case has.  I want to output a square of a certain frequency with the task frequency meter pulse output and then read the frequency of this signal using a task of cost input frequency.  I don't know how to property set up these tasks, or how to define which device to use for each heap.  I don't know what terminals on the BNC-2090 is the counter of entry/sortient channels correspond to them because that is not displayed in the documentation of the PXI-6133 or documentation of BNC-2090.

  Please see the attached VI for my attempt to put this in place.  Currently, I get two errors:

  (1) error-200452 took place at the property Node DAQmx channel meter Test - referred to as property is not supported by the device or is not applicable to the task.

  2. the error-89136 at DAQmx Start Task - specified route cannot be met because the hardware does not support.

  If I remove two channels of property DAQmx where I try to put the terminals for the counters, while the program is running, but then I know not what terminals on the BNC-2090 meters are connected to!  This causes the DAQmx read for the cost in the tasks of frequency to timeout because it does not detect a signal.

  I would really appreciate the help to properly configure these tasks and determine what terminals on the BNC-2090 case has the task of counter will work on.

  I see a few problems in the code originally:

  1. For your CI task, you type is defined as a counter entry > frequency.  But on the node property of DAQmx channel for this task, you modify the CI. Property of PulseWidth.Term.  It should be CI. Freq.Term. set the entry regardless of the PFI line you do not want the input signal on.  Tip: you don't have to type the name of the device in at all.  Enter "PFI0", it's the same as "DevN/PFI0" since the unit has already been specified in the DAQmx Virtual Channel Create function.  The name of the device, leaving aside will make your code more flexible where you decide later to change the name of the device.
  
  
  2. Maps of the S series, such as the 6133, do not have the same flexibility to change the output terminals of tasks of meter you might find with M or X series device.  Page 83 of the S series manual watch what signals can be extracted to PFI lines - Ctr0Out is not one of these.  Instead, Ctr0 out is, by default, pin 2.  Cabling to a BNC-2090 6133 is certainly difficult to understand out (probably because the 2090 was designed to work with the materials of the E and M series), but if you compare the pinout of a PXI-6255 0 with the 6133 pinout connector, you will notice that they are essentially a match 1-1.  Pin 2 is PFI12 on the 6255, so I assume the same for the 6133.  All this to say, Ctr0Out always appears on the pin 2/PFI12 for the 6133 and you therefore cannot change the output terminal that your code is trying to do, having for result error-89136.  Remove this node from the property altogether and the error should disappear.

• Error-200279 with PCIe-6363

  I currently have a simple vi used to acquire data of tension through the DAQ assistant permanently.

  Currently I'm collecting 2 channels sampled at 200 k continuous (due to random events).

  No matter where I put the samples to read, I have several times: error-200279.

  Some other posts, I assume it's because the DAQmx read function and the function "write on a file" are producing at different speeds, causing a shift of data may be.

  To resolve this problem, should I apply the design of producer/consumer model? And if so, I may receive advice on how to actually that implement with my current vi?

  Hi davd24,

  We always recommend to file i/o functions in a separate loop of read/write functions DAQmx. It resembles what is past in your case, is that the time it takes to write to a file is longer that it takes to fill the device aboard the buffer that throws the error you see. Therefore, I suggest the architecture of the producer consumer. Here is a link to a tutorial:

  http://www.NI.com/white-paper/3023/en/

  Also, here is a link to an example of Community produce consumer with DAQmx features:

• Error-50352 to DAQmx analog writing

  Hello

  I get the following error message when you try to write data points about 20 million to a Council of PXI - 6713:

  Error-50352 occurred at DAQmx Write (Wfm Analog 1Chan NSamp) .vi:1

  Task name: _unnamedTask<1>

  I don't understand the error memory. When this happens, use LabVIEW is, according to the Task Manager Windows, only 750 MB of memory, perhaps 950 MB max, and I ran things successfully when LV was used 1.6 GB of memory.  I have increased my settings of virtual memory to 3 GB for Windows Vista 32-bit. I have 4 GB of memory total, and I have a core duo 1.8 Mhz CPU.

  My VI is attached. I read in a waveform of singles, do a conversion in rooms double and try to write to the Commission. I use DAQmx calendar sample clock instead of "Using the waveform", because using the sample clock results in one less copy of the data. I read the data in singles because that is how I write in advance, and it is much faster to read in simple it is double.

  Hi Djaunl,

  I ran your program with a DDHN file that I created and got the same error your saw.  I then ran the program with highest point running on - the light bulb it the top of the block diagram. I found that the error occurs on the second loop.  This leads me to believe that it was something to do with the implementation of the task.  When I replaced the clear DAQmx with DAQmx stop and this solved the problem.  The reason that this solves the problem, it is the DAQmx clear clears the task each time that the loop runs, thus freeing up your calendar information.  Whe you switch to stop DAQmx, task configuration information are not totally clear and the error is resolved.

• Help! Export error 27 with only a few videos

  I exported Final Cut Pro X projects directly on my external hard drive. I got an error 27 with one of them, and given that it is exported well I don't think it's a problem with my external hard drive formatting. All the videos have been imported in the same way and the same camera. Any ideas about why this is happening? Thank you!

  Most likely, you export a FAT32 / 'Windows' formatted the disk, right?

  error27 occurs when you attempt to save a file > 4 GB - that is not supported by fat32 (very old format..)

  So, small export projects, larger not. -.

  reformat the drive (erases all content!) to exFat or hfs + / "Mac"...

• Timing embedded with Daqmx on PCI-6132

  Hello

  My colleague and I are trying to make a program Labview which starts a timer when the first trigger (sensor) is struck and stop the timer when the second trigger (sensor) is reached in 2012. We currently have a program for her, but this program was not sufficiently precise. Also the current program is using the DAQ assistant, but we would like to replace with daqmx triggering. We have also tried to use the OnboardClock on the PCI-6132, but still could not do the work programme.

  Is there anyone who knows how to do this and could explain it?

  (In the attachment is the current program)

  Thanks in advance,

  Hello Tommy.

• Is it time stamp with daqmx read

  Hi all

  Simple question.  I have currently not creating a task or starting a task, I simply create a channel and reading that chanel.

  It is...  Why I don't get a timestamp when you do and do I create a task to get one of this?

  There is a timestamp when you use the DAQ Assistant or when you choose to return a data type of waveform with DAQmx Read.

  You can't do a reading without a blemish. You don't have to create the task in MAX, however.

• Multitask with daqmx

  Hello

  I am currently working on a Senior design project where I have to measure rpm, torque, pressure and temperature.  I use strain gauges, pressure sensor and a Hall effect sensor, thermocouples for these readings.  A myDAQ collects readings rpm and pressure while a cDAQ collects couple and readings of the temperature with NI 9211 and NI 9237 modules.  I have created LabVIEW screws for each sensor and they work.  The problem I have is when I try to create a VI with DAQmx who reads all the values of these sensors simultaneously.  The VI I joined randomly displays one of the measures while other measures remain empty.  How can I change my VI so I can show all my readings at the same time?

  Yes.  Create multiple tasks, where all the strings that are common to a specific device are grouped in the same task.  Then go and run these tasks in parallel.  Do you need a precise synchronization between the tracks in the different devices?  If this isn't the case, then the method should work perfectly.  If you need a precise timing, things would get more complicated, but might not be impossible.

• time of release with daqmx

  Hello

  How can I set the time of liberation with DAQmx?

  In general, with a single DAQ hardware, the two signals are connected at the same time and the acquisition time is a function of the sampling frequency and number of samples read. For example, with a sampling rate of 1000 samples/s and 50 samples, the acquisition will be 50 msec. You then get a returned array if you wanted to watch a single signal by iteration of the while loop, it is simply a matter of indexing the specific channel to the table. You must set the mode of continuous sampling to avoid gaps and precise timing. Using two separate tasks and switching back and forth would add a lot of overhead to close/create tasks and you have little control over this period.

• 2009 with DAQmx Installer

  We distributed an integrated application that uses DAQmx 8.x and LabVIEW 8.6 for several years.  I'll call the application MyApp 2.8.  We are working on a new version that uses LV 2009 and DAQmx 9.x, which we will call 3.5 MyApp.  When build us and deploy a Setup program for MyApp 3.5, then try to use it on a computer that already has 2.8 installed MyApp, the installer complains about dependencies and said that the two DAQmx 8.x and MyApp 2.8 must be uninstalled first.  I spoke NOR cela briefly and told me that DAQmx 9 was a pretty radical overhaul that required this change.

  It's annoying and slow for us, but almost untenable for our customers.  First of all, MyApp MyApp 3.5 and 2.8 are compatible, and we prefer to leave MyApp 2.8 installed as a backup as people get used to 3.5.  If the customer needs:
  Uninstall MyApp 2.8

  Uninstall DAQmx 8.9

  Install MyApp 3.5 with DAQmx 9.0

  Reinstall 2.8 MyApp (as if they can still find the disc!)

  Far too many steps and complications.  In addition, it is not really necessary.  If the runtime for 2009 is already installed on the computer (for some reason any), you can simply copy the MyApp 3.5 on the computer and it will run with DAQmx 8.9.  But this only postpones the problem, because at some point the customer will upgrade once again, and we will have forgotten that they were installed with a workaround, and...

  The really frustrating part is setup for MyApp 3.5 refuses to install until MyApp 2.8 is uninstalled.   While we have proven that MyApp 2.8 will work very well with DAQmx 9.0.

  Is anyone else noticing this problem?  Has anyone found any better workaround?  Is the same problem when we jumped 2009 and returned with 2010 and the last DAQmx?

  Thank you

  DaveT

  DaveT,

  You're right - for this aspect of the problem - my proposed solution won't help. At the price of a larger Setup program, including the full version of DAQmx probably will give the upgrade experience you want. If the web download size is a concern, perhaps you could provide two builds of your product - with the acquisition of complete data (for those of you who have your old product) and with smaller data acquisition (for those who do a clean install)?

  In addition, certain registry keys to remove the dependency I guess hacking is sort of an option, but it probably isn't the type of solution you are looking for. (We are currently researching the addition of some extra features in the uninstall program OR allow without taking account of certain dependencies, but nothing is currently available).

  Kind regards
