Error 200587 DAQmx beginning to Task.vi:

Hello

I'm having a problem similar to what is described in this post.

It's a fairly simple setup, but I can't make it work right.

The engine of a valve control, I created a class to help me.

My method takes a number of pulses and direction and use DAQmx I put management and call another method to generate the square wave.

When I run all separate I have no [slow] problem when I change the pulse by hand. When I try to put that in a PID loop, I get an error. I tried a few different approaches, but I'm starting to run out of ideas... Any help I can get I like you a lot.

One of my hypotheses is that I am trying to send a new impetus [sqw] until the channel is free again, but I got the same after that I tried to slow down my loop pid to 5000ms.

Acquisition of data USB-6009, LV2011, Win7

I use 3 digital output:

-D00 a software clock [wave square pulse + - 200 Hz]

-D01 for management

-D02 for power.

200587 error occurred to DAQmx departure at Task.vi:

Possible reasons:

Requested operation cannot be performed, because the digital lines specified are reserved or the device is not present in NEITHER-DAQmx.

It is possible that these lines are reserved by another task, the device is used through the interface of NOR-traditional DAQ or the device is reset. You can also get the error if the specified resource is currently used by LabVIEW network variables related to the acquisition of data string, or if the data acquisition channel is used in any OPC Client software.

If you use these lines with another task, wait until the task is complete.  If you use the traditional device through NOR-DAQ interface and you want to use with NOR-DAQmx, reset (initialization) the traditional device using the NOR-DAQ interface. If you are resetting the device, wait for the reset at the end.

Device: Dev1

Task name: _unnamedTask<3FFB>

Hi Ibanez,

The suggested VI should work, and if you write a channel for each line, it should work also. To return to what will be the main task that you want to achieve?

Kind regards

  • -Error 200587 on recreation of task

    I have a digital camera line that needs to be reset with various trigger parameters according to some options of the user (on a digital advantage or no trigger trigger). First time around I can create the task without problem. But when I then have the task and recreate it, I can't start. I get the error-200587. My .net code is below

    THIS CODE RUNS ONCE

    t = new Task();
    t.DOChannels.CreateChannel (line, name, ChannelLineGrouping.OneChannelForEachLine);
    Writer = new DigitalSingleChannelWriter (t.Stream);

    Writer.WriteSingleSampleSingleLine (true, we);

    THIS CODE REPEATS

    If (t! = null)
    {
    t.Dispose ();
    }

    If (t! = null)
    {
    t.Control (TaskAction.Abort);
    t.Dispose ();
    }
    on the other

    t.Stream.WriteRegenerationMode = WriteRegenerationMode.DoNotAllowRegeneration;

    t.Start ();

    Writer.BeginWriteWaveform (true, form of wave, null, t);

    One strange thing I noticed, is that the error occurs exactly 2 / 3 times, that is to say: +-+-+-...

    Any ideas? Maybe I can get what I need here another way?

    I did debug this. In the op, I posted just the code base, to remove all methods and referenced objects so that it is easier to understand. When I wrote a program in this manner (all in a single class, not the objects referenced), the problem seems to go away.

    It seems that there is something that delays the proper disposal of the tasks.

    In my original code, I have a class of "DigitalOutputChannel", which includes the task and all his companions. I realized that I actually have a copy of this whenever I have cycled through the code, instead of simply re-use and redo the task. It is possible, that the disposal of garbage .net wasn't up to that every third cross, allowing it to function again properly.

    The code works now!

  • DAQmx error CREATE AN intermittent-229770 TASK

  • How to clear the output buffer, possibly resize and burn again, before you begin the task of output

    I use PyDAQmx with a USB-6363, but I think the question is generic to DAQmx.

    I have an output buffer that I want to be able to (re) write to without starting the task output.

    More specifically, I have a graphical interface and a few sliders, the user can move.  Whenever the slider changes, a new set of values is loaded into the buffer output through DAQmxWriteAnalogF64.  After you set the value, the user can click on a button and start the task output.

    In some cases the change in cursor does not require a change in buffer size, only a change in the data.  In this case, I get the compalint following DAQmx as they tried writing:

    The generation is not yet started, and not enough space is available in the buffer.

    Set a larger buffer, or start the generation before writing data more than content in the buffer.
    Property: DAQmx_Write_RelativeTo
    Value: DAQmx_Val_CurrWritePos
    Property: DAQmx_Write_Offset
    Corresponding value: 0
    Property: DAQmx_Buf_Output_BufSize
    Corresponding value: 92

    In other cases the change in cursor requires both change in the size of the buffer and data modification.  In this case, I get the following, but only after that do a few times each time increase the size of the writing.

    DAQmx writing failed because a previous writing DAQmx configured automatically the size of output buffer. The size of the buffer is equal the number of samples written by channel, so no additional data can be written before the original task.

    Start the generation of before the second writing DAQmx or set true in all instances of writing DAQmx Auto Start. To gradually write to the buffer before starting the task, call DAQmx Configure an output buffer before the first writing DAQmx.
    Task name: _unnamedTask<0>

    State code:-200547
    function DAQmxWriteAnalogF64

    I tried to configure the output via DAQmxCfgOutputBuffer buffer (in some cases, by setting it to zero or a samples, then save again, in an attempt to clear it) but that doesn't seem to do the trick.

    Of course, I can work around the problem by loading data only when the user clicks the end button, but not what I'm asking here.

    Is it possible to "remake" the writing of output before you begin the task?

    Thank you

    Michael

    Today I have no material practical to validate, but try unreserving task before writing the new buffer:

    DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Unreserve);

    With a simulated device, he made the error go away in case the buffer is the same size.  You will need to validate if the data are in fact correct, but I think it should be (unreserving I would say reset the write pointer so the old buffer are replaced with the new data).

    I always get errors when you try to change the size of buffer if (on my 6351 simulated).  I posted some similar mistakes about the reconfiguration of the tasks here, I guess it is possible that this issue has also been set at 9.8 (I always use 9.7.5 on this computer).  If the behavior is still present in the new driver, and also appears on real hardware (not just simulated), then it seems that this is a bug of DAQmx someone at OR should be considered.

    I wrote a simple LabVIEW VI that captures the error in order to help people to NOT reproduce it:

    The best solution at the moment would be likely to re-create the task if you need to change the size of the buffer (or avoid writing data until you are sure what will be the size of buffer).

  • task error DAQmx beginning-88709

    Hi all

    I have a chassis PXI-1045 filled with modules of the PXI-6120 S Series digitizer. I started to have problems when lance VI, receiving daqmx error task start-88709, indicating that a device has been removed or abandoned task. A clock device had been exchanged for the pxi-6653 to 6651 and re-configed at MAX (4.7). I found that text of presentation on this site about this was a problem common to all versions of DAQmx device before 9.2.2 drivers even if I had never seen him before the swapout of the card. 9.2.2 upgrade was the recommended fix that was done without problems. However, the problem persists. Now I also have a new problem on shutdown of a task, editing and restart the task. The clock and trigger signals are there... If these issues are linked and does anyone have a solution?  Thank you!

  • Error 200077 (frequency) and 200452 (task control loop) error occurred DAQmx create calendar Source.vi

    Hello

    I'm trying to control the timing of a timed loop. So far, I have tried several approaches via the software and which worked very well except the time loop in some missed cases 1-2 Ms I want to make sure the timing is right. I tried to provide an external clock through the acquisition of data I. The system I use is NI USB-6212. It has two counters and DIO and AIO, but I keep getting errors. I tried two different approaches. One was to use directly the game 'DAQmx create calendar Source.vi' in frequency mode, and when I did, I got error 200077. Then I found a post of somone saying that sometimes it is not possible and an alternative method is to use the same vi but set task of loop control mode. This one gave me Error200452. For this one you will see in my attachment the suggestion was to use an AI then the moment of him and then use this task for Creat DAQmx synchronization Source.

    I don't know what the problem is or if I need to put something differently.

    Please let me know if you can help me with this.

    I'll try to continue to work on that, but if anyone of you a suggestion I'll be very happy to consider the issue.

    Thank you in advance,

    Best, Massimo.

    Massimo,

    In my view, the errors that you see are the result of your hardware USB-6212 is supporting the functionality of the task control loop.  I have a M Series PCI card that is capable of operating both of your screws attached without problem (although they still +/-1ms variation on occaision).  When I try to use a USB-6212 simulation, I get the same error codes that you do.  Unfortunately, it's just a case of a lack of equipment.

    Kind regards

  • Error reading DAQmx multichannel. DAQmx believes that there are several channels in my task.

    Hello

    I get the error message added when you try to use my VI DAQmx Read.  LabVIEW tells me that I'm trying to read a single channel when my task is configured for multiple channels.  However, as you can see in the task panel, this is not the case!  If I try to use DAQmx Read to generate a waveform with many channels, the VI runs without error, but I don't want a picture of waveform 1 d...  Any tips?

    Kind regards

    Steve

    Without seeing the code all I can offer only a possibility.

    Something else in your code is changing the task of wine and let the reference.  Wine is then stored with many channels, but these changes are not saved to the MAX which means that when the task in this section of code is not identical to the task UP.  Hit a knot DAQmx task over there and read 'Channels' to confirm my suspicions

  • Sequence special error in DAQmx create raster scan with 2 Motors of stepper motors: Error Code 200088

    Hello

    I am trying to create a LabVIEW program that controls two bipolar motors to create a raster scan. I use DAQmx and Labview 2012 SP1 with a usb 6008. I got the engines to move in one direction, but when I try and get them to move in another direction in a separate task, I get an error-200088 code indicating that my task is not valid. This happens at the beginning vi to move the motor x in the opposite direction of the task.

    The logic underlying the program is as follows:

    1. move the engine x a certain number of steps to the right

    2. move the engine are a number of steps down

    3. move the engine x the same number of steps as 1 to the left

    4. get off the engine is the same number of steps 2

    5. repeat

    I can get the steps 1 and 2 work but I have problems with step 3. I use a stacked sequence to show the task for each step.

    I appricate all the advice on this topic as part of a final year project

    Thank you

    Aoife

    You can solve this problem very simply.  Move all DAQmx departure calls happen * before * the structure of sequence rather than inside.  Similarly,.

    move all calls to DAQmx Stop and DAQmx Clear happen * after * the structure of sequence rather than inside.

    I would sequence the DAQmx Write calls to write the bit of direction * before * writing the bit clock.   And I highly recommend that wire you

    to the top of your tenants error and outs so you can be informed of any errors in the DAQmx tasks.

  • Error-50352 DAQmx: How can I determine the maximum size of the buffer?

    I use a card PCI-6259 with DAQmx (version 9.0.2) library and I get the error "-50352: memory cannot be allocated" whenever I try to make my record too long. Here are a few terms that I found:

    1 channel of AI, 1Msample/s: 7.71 sec max

    1 channel AO, 1Msample/s: 7.71 sec max

    1 channel of AI, 500ksample/s: 15,4 sec max

    2 channels of AI, 500ksample/s: 7.71 sec max

    1 HAVE, AO, 1Msample/s 1-channel: 5.6 sec max

    IF I can't acquire more 7.71 Msamples in a single task, be it in most cases, or AO. When you mix tasks HAVE and AO, this limit seems to be decreasing. This happens with a freshly started application, so I don't think that it is a question of compensation task.

    What is a physical boundary with the device? (And if so, how can I determine this limit?)

    My impression is that the device uses DMA to transfer samples to the system memory, which there are plenty - I can easily allocate more than 400 MB of contiguous memory in the same application.

    Hi Luke,.

    The amount of RAM your system installed?

    What operating system do you use? If it is a 32-bit operating system, using 3 GB or increaseuserva? These parameters have a compromise: they reduce the size of the kernel virtual address space. This increases the probability of DAQmx will succeed to allocate memory but do not reach the mapping in the kernel virtual address space.

    Your system has all the devices with very large memory mapped I/O beaches, such as a video card with a large amount of memory on-board? On a 32-bit operating system, this can reduce the size of the virtual address space of the nucleus by a significant amount.

    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!

  • Difference between DAQMX and DAQMX base. Task list empty

    Hello

    Can someone please explain the difference between NOR-DAQMX and NIDAQMX base?

    I have recently installed Labview10.0 and NOR-DAQMX base on linux opensuse 11.4 3.4.0. Everythinng works very well. The device is recognized by labview and I put my controller and chassis using nipxiconfig. The DAQ assistant function is missing and also the drop down task and channels is empty, even if I create a new task using the basic NIDAQMX configuration utility.

    Can you get it someone please let me know where I'm going wrong?

    Thank you

    The DAQ Assistant is a Windows program only, DAQmx only.  It not Linux or with DAQmx Base.  DAQmx basic tasks and channels are a little different (I think) counterparts DAQmx.  The fall to the bottom of the list of basic parts, or is it only DAQmx?
