• Cleared task status

  Hello:

  I use DAQmxClearTask to delete a specific task.

  Is there a way to know that a task has been authorized already uses library of NOR-DAQmx features?

  Thank you

  -Ilya.

  I think that any operation on a cleared task would result in an error. So just do something like reading a property node and check the error code.

• 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)?

• How to open PDF files across multiple desktops in Windows 10 Adobe Acrobat Reader task view?

  I am running Windows on an Acer Aspire S7 10.

  The question is, when I open a PDF on your desktop and then move to another office using Windows task view, I can't open a new PDF file open on the new office. What is the reader is that it opens the PDF on the originating office.

  Could someone suggest how to solve this problem, which is to make a file PDF open in new office and not the original?

  Thank you.

• DAQmx clear task

  Hello Experts,

  Please find attached an auxiliary DI litte loop, which I use in a larger application. The DAQmx task is created in the LabVIEW project.

  -Can I use it as Version_A or

  Close task as in Version_B?

  Someone suggested once I could create a memory leaks using the version A - is that correct?

  Thank you

• Analogue out after clearing the task

  Hello

  a quick question on AUG. I have create a task, write the analog voltage appropriate to the line, can stop the task and finally clear, task.

  After all, the level of tension on the material NOR rest on the exit. Is this normal? The question is: is this a normal behavior and I use the OD of this way, or the task takes to run/oper?

  concerning

  Mitulatbati

  Yes, it's normal. "" You can change the output to 0 or use the Reset DAQmx VI (which will change the output to 0) located in the measure i/o "NOR-DAQmx" Dev Config pallet on the block diagram before you quit the application.

• Clear any open task daqmx

  Hello

  I was going crazy, because all of a sudden a tasks analog output did not work any more he said it conflicted with another task "always active"... I searched my entire application. Could not find anything. So finally, I closed the application labview together, and then it worked again, as if by magic. I came to the conclusion, that my stop and and clear task was not called when I closed my program in a different way.

  So my question: is there a possibility to see what daamx tasks are active when you start your program, so that you could erase any existing task?

  Kind regards

  Better yet, DAQmx tasks really need to be created once, preferably during development and no runtime if you can avoid it at all the.  Presist them to the project (if you are deploying in a debug environment) or, for MAX, if you deploy a exe.  It also allows your tasks be available for troubleshooting and integration, or even a FPS "Engineering" for the station.  I don't remember the last time I've delivered a solution the DAQmx encluded create Task.vi.

  Its pretty easy to write yourself a little utility to give up and cancel all tasks DAQmx.

  

• Explanation to Pause a task

  Hello guys,.

  Ich have a little problem to understand what happens when I stop a task.

  A little explanation of my program:

  I generate a signal over time. This means that I give the program of the amplitude, frequency and time how long signal must be performed (for example 10 minutes).

  In order to have a better time of calculation, I do the following. I initially generate a first sequence und write it in the buffer (quantity defined samples). Then I start the task.

  So now the samples is transferred from the buffer to the device. I wrote a callback function (int32 CVICALLBACK OnEveryNSamplesEvent (TaskHandle taskHandle, int32 everyNsamplesEventType, uInt32 nSamples, void * callbackData)) which generates the following pattern when the first batch set of samples are transferred to the device. This has the advantage that I can't calculate a very large table at the beginning of the program instead I calculate every time a part of it at the same time when the buffer is written to the device.

  Then and now to my question.
  I don't know what happens when I break the task (DAQmxStopTask (taskHandle)
  I tried and it has the function, I would have but is there the risk that my buffer can cause an overflow? Is the set of the program as the calculation in the background stand still when I break the task?

  (My theory is that, with DAQmxStartTask (taskHandle), I'm starting to transfer the samples of the buffer in the device. When I stop the task he doesn't transfer the samples more and then the calcualtion in the background also still stands)

  Hope someone can give me the right solution to the problem.

  Best regards

  Hello Fasching_K,

  What is the difference between the DAQmx stop VI and VI DAQmx of the clear task task?

  It is interesting here

  When you perform operations of analog output, you must write a buffer of data to the FIFO output before the intervention. Indeed, this will move the task to a State of 'reserved', before calling the DAQmx start task VI (who puts in the 'race'). When the task VI DAQmx Stop is called, it puts the State of the "race" to the "reserved", so any attempt to start the task with different values generates an error.

  In your case, you have stopped the task with this one stop also not write values in the buffer, so normally no overflow would take place.

• compensation tasks automatically at the start of the program

  When you run a LabVIEW program, periodically, the program stops in the Middle, and the function of the clear task was not able to run.  Of course, by operating the next LabVIEW program, I get an error.  Is there a way to delete all tasks on a data acquisition or MAY at the beginning of a LabVIEW program to ensure that the program you are using does not work in a problem since the previous task has not been cleared properly?  I was expecting just a drop of water in my program.  Any help would be appreciated!

• DAQmx task deletion concern

  So when I use the DAQmx create channel VI, he creates a task 'unnamedTask xx' where xx is a hexadecimal number. Let's say I put the State of the task of checking. Now, if they are in a loop, it will create then another task, use the same physical channel and because it is the only reservation it will create another task, increment the unnamedTask 1 and set it to check. My question is, what happens to the previous task? If it is stored in memory? Or the garbage collected. I guess that since the material is assigned to another previous task will be garbage collected. But I wanted to make sure. I have several tasks, so if I can avoid using the task clearly and simply overwrite it somehow be better I think. Thank you.

  Brad

  You can call DAQmx clear Task.vi between create a task and Create Channel, which will erase any existing configuration and will not mistake if the task does not exist.

• Close task DAQmx freezes

  Hi all

  I've been struggling for some time with the following problem, no relevant answers to it. Maybe someone here have met it before.

  I wrote a program in 2011 Labview data acquisition, using daqmx 9.3 + acquires data from a card NI 6008. The program works very well at all works with my laptop, but crashes during like every third performance on another laptop. Both have win7, the other is 64-bit (I'm not sure that matters).

  The program itself is quite complicated, so here I PASE a image of one of the parts he tends to freeze at (there are many other acquisition tasks, where it delimits to freeze, but every time that the structure of the block diagram is basically the same, with the creation and closing of the task). It is freezing more often when there is continuous sampling frequency of 1000 Hz and simultaneous treatment (trace, fft, etc.), in a regime of producer/consumer. The interesting thing is that it does not ALWAYS freeze.

  Whenever I check if the program hangs at the TASK.vi STOP without sending an error message. I can produce the same error with the simple example, I have insert below, if I run the program several times (it takes 10-20 tracks of stick to stop task.vi)

  Please, send any suggestions on what could be the problem.
  Another tip is the MAX itself gives an error of "embedded memory overflow", several times at startup. However, I tried the solution with the property node - without success.

  Dear Buadam,

  The workaround you mentioned has been implemented in NOR-DAQmx 9.4 and should be available from this version. The default value of value certainly not 1, since that would limit USB flow considerably, especially on faster devices.

  To explain more in detail: this property ("Analog Input" General Properties"Advanced" transfer of data and memory"County transfer USB) is responsible for defining the size of a USB transfer burst. The default USB transfer size is 32 KB. For a very fast channel or high County applications increases the size of USB transfer request are likely to increase flow. In this case however, we are voluntarily reducing the size of the transfer, to be absolutely sure that the bug in Windows 7 (how the system handles applicants on USB 2.0, specifically, how the packages are split) does affect us, resulting in deadlock as you packages known. So the idea here is to small enough packages to ensure that the USB driver is unable to divide, this prevents in turn also USB performance, but since the 6008 is a relatively slow, low peripheral County channel, we always have more than enough bandwidth.

  So, to summarize:

  • Please update on DAQmx 9.4 or more if you can (LabVIEW 2011 is supported up to the most recent, version 9.8)
  
  
  • I also recommend to upgrade the USB drivers from the laptop from the website of the provider as appropriate.
  
  
  • Set the AI. UsbXferReqSize to 1 once available. If you don't find it, try right-clicking on the property node, select filter... > display all attributes

  crossrulz: you have effectively reason that a finite measure stops the task once all samples have been read, so a wait until I recommended is redundant here, as it is expected to return with fact = True. The reasons why I suggested to use are:

  1. To refresh the status of the task, "check" that he has been arrested properly.
  
  
  2. To give the device of the extra time before the command stop the task/Clear task is sent.
  
  
  3. To catch errors that are stored in the DAQmx object, but not covered by the read operation, before attempting to stop/clear.

  Hope is makes sense.

  Kind regards:

• Cancel the task which is not yet completed writing

  I'm generating analog signals via DAQmx - these signals may be > 10 seconds long by necessity (the sampling frequency is very low). I would like to be able to stop the release of the wave when I press a button. What happens now, when I use the clear task vi, Labview is waiting for some time and generates an error (error-200292, some or all of the samples to write might not be written in the buffer still.) More space free that come samples currently in the buffer.) The task is disabled afterwards, which is what I want, but I don't want the waiting time. Is it possible to interrupt the task writing? I know that it is theoretically possible, because I can't stop the vi and production stoppages, but this isn't really a workable solution.

  Thank you!

  Thanks guys, but I thought about it - there was a timeout entry when I started the tasks that I had forgotten to wire, and it was set to 10 s. What makes smaller solved my problem.

• Output.VI - Digital missing as well as other vi'

  I'm trying to run a vi that if interface with a chassis pxi, but when I open the vi missing several sub vi.   "Such as"-Digital output.vi ', ' DAQmx clear Task.vi ", DAQmx Start Task.vi", as well as 'DAQmx create Virtual Channel.vi' Poly VI, "DAQmx READ.vi" along with assorted others.   Any info on how to fix this problem would be greatly appreciated.  In my view, that it was created in Labview 8

  What are the versions you have installed?  Do you have what DAQmx version installed?  Which version do you want it to run?

  Since you say there are several versions of LabVIEW installed, I'm guessing that you have a newer version of installed DAQmx that can use LabVIEW 8.2.  Try to open the VI in your latest version.
