• Error-200279 was held at lu DAQms (analog 1 Wfm NChan Nsamp d) .vi2

  Hello

  IM taking technical temperature (thermocouples of type J) with the SCB-68 using PCI-6229. When I run for a relatively long time I get this error.

  It is said

  "Error-200279 took place to read DAQms (analog 1 Wfm NChan Nsamp d) .vi2"

  Possible reasons:

  Measurements: Tried to read samples that are no longer available. The example of requestred was already available, but has since been replaced.

  Increases the size of delete, reading data more frequently or specifying a sets of samples read instead of all samples available moght correct the problem.

  Thank you

  First of all, you should always label on the block diagram control terminals so we know what the purpose of each terminal.

  The problem is the misuse of the Express VI.  They are perfect for something to get up and running quickly, but they have such high overhead and cannot be modified for more advanced features, there are problems quickly.

  Writing on file inside the loop of data acquisition could be a problem.  If you have a slow down in writing file, it will slow down the whole loop.  It's a good idea to use producer/consumer architecture to pass data to the other lines for writing file.

  I think your main problem is the express VI build Table.  Why you see thousands and thousands of datapooints in a table.  Because the table developing the table of handling inside that Express VI will quickly slow as LabVIEW as for finding still more large blocks of free memory to contain the growing table moving constantly in memory.  The global loop slows down as well, and until you know your buffer DAQ as overwhelmed because you couldn't keep with reading the data.

  Get rid to build Express VI Table and table and try it without the people.  Your problem will probably go away.

• Stuck in the error-200279

  My program involves several DAQ tasks that run in unison, as in the example of "Multi-multifunction-Synch I-AO. Works very good in general, but if anything it either never interrupts the flow of the program, I'm stuck permanently with the error 200279. Here is the precise relationship:

  Error 200279 occurred at DAQmx Read (analog 1-d Wfm NChan NSamp) .vi:1

  Possible reasons:

  Attempted to read samples that are no longer available. The requested sample was already available, but has since been replaced.

  Increase in the size of buffer, most frequently the reading of data or by specifying a fixed number of samples to read instead of reading all available samples would correct the problem.

  Property: RelativeTo
  The requested value: current playback Position
  Property: Offset
  Required value: 0

  Task name: input analog

  And once I am in that State, the only way I can find out is to kill and restart all my tasks. There must be a better way? How to resync the computer firm asking former samples and welcomes those who are there NOW?

  Here are a couple of reliable means to bring about this problem: 1. reach a breakpoint during debugging. It's very frustrating when you can't use a breakpoint without destroying the same operation you are trying to debug. 2. the user presses a button that opens a file dialog box. Even though my main program consists of several parallel loops, and the dialog file is called from a DIFFERENT LOOP that makes the acquisition of data. It's a problem anyway. How can I make a file dialog box without stopping my stream of data acquisition along the way?

  Help much appreciated. This problem stop my program to be the work of industrial power that needs my scientific users.

  Thank you
  Ken

  Ken,

  You can specify DAQmx what samples in the buffer to read.  By default, DAQmx will read the 'current reading position.  What you see is that the data not read from "current playback position" got too written with new data.  Basically the data that was in the 'current reading position"no longer exist, and try to read from that location you causes the error you see.  DAQmx does not specify where it reads data since.  You can use the property Read DAQmx node to specify what DAQmx reads Relative to, but also a shift here in the buffer.  It is possible that if you detect this error, you can read from 'most recent sample' for a reading.  This would throw essentially all of the data in the buffer between the "current playback position" and the most recent sample in the buffer, but would allow your application to continue, as it is equipped to address the shortcomings in the data.

  Hope that helps,

  Dan

• HAVE DAQmx error-200279

  I run a loop with a N-Chan AI read vi, out its values in a queue which is read by the other parallel loops.  During the operation of the program, when the other loops treat their queues and (from what I can tell) occupy time processor, read it loop returns a 200279 error, saying:

  Error-200279 to AI Read.vi:7

  Possible reasons:

  Attempted to read samples that are no longer available. The requested sample was already available, but has since been replaced.

  Increase in the size of buffer, most frequently the reading of data or by specifying a fixed number of samples to read instead of reading all available samples would correct the problem.

  Property: RelativeTo
  Corresponding value: current playback Position
  Property: Offset
  Corresponding value: 0

  I am quite puzzled as to why this error keeps popping up.  No one knows what the first cause of this error is usually?

  Hi Jeanius, in my view, that this articlecan explain your problem.

• Why 'Read a fixed number of samples' help with the error 200279?

  Hello world

  It is a question about a tip found in the explanations on the acquisition of data error-200279. This explanation it is said: '... ". reading a fixed number of samples instead of all available samples can fix this... »

  AFAIK the DAQ system buffer is a ring buffer, so we can consider having a writing position and a position of reading "in motion" along the ring. While the playback position is the position of writing, everything is brilliant. But if writing catch up reading, samples will be overwritten and therefore-> error-200279.

  So here's my question:

  I do not understand why a fixed amount of reading samples would help me with this error. I don't understand why other Councils (increase in the size of the buffer or the frequency of reading) would help me because they reduce the probability of the playback position being outrunned by the position of the writing.

  But if I read everything which is available, whenever I read the only way for the buffer fills would be that the time between two readings take more time than necessary fill the entire buffer.

  Or in other words to each reading I will read at least as many elements that it has been filled by writing since the last read, so the only way to fill the buffer would fill completely at once since the last reading.

  This should be a lot safer than reading a fixed amount, because in this case, I'd get a problem if I read it that fewer items than writing complete at the same time, regardless of the number of items that would be and no matter what the size of the size of the buffer that would be.

  What I understand here?

  Thanks and regards,

  Sebastian

  SBach wrote: this VI is a State Machine in queue, the reading part is made in the case of timeout and cases are used as initialization orders, stop and change the outside DAQ hardware.

  That I can't tell when these commands will trigger the time between two readings could not be set. If a strictly fixed amount of data could lead to a buffer to fill.

  Init command: you certainly don't have a running task.

  Stop: You stop the task, then doing here if you get overrun.

  Edit tasks: you will probably need to stop the task still before you can edit the task, but let's go back to not caring.

  The way I see it, the other commands must stop the task anyway.  If you can leave the timeout do its job and do not do a lot of extra stuff.

  And here are some alternatives:

  1. use a shift register to keep track of how long your wait time should be.  In the case of reading, make the deadline to be whatever it is that you are using.  In all other cases, only the 0 so that a read timeout must be performed immediately (once the queue is empty).

  2. When you do your check to 1.5 times the timeout, if there is too much data, queue a reading at the front of the queue so that playback will happen.  The idea is that you really want to keep the same stack sizes to keep the memory to be allocated.  So just to be read more often.

• Error 200279 and slow program running

  I read a lot of posts about this error but still cannot fix mine. During the execution of the program realizing measures of error 200279 turns suddenly upward. In addition, the program is very slow; I'm trying to read data from a QD and a PSD (two different position detectors) and when I move a detector (QD or PSD, it doesn't bother me) the program response is too slow. I tried to correct the error by setting the value for timeout - 1, but the error is still there. What can I do?

  Thanks in advance,

  P.D.: Error 200279: tried to read samples that are no longer available. The requested sample was already available, but has since been replaced. Increase in the size of buffer, most frequently the reading of data or by specifying a fixed number of samples to read instead of reading all available samples would correct the problem.

  You need to understand why your VI is so slow.  It go fast then slow down over time?

  I see a lot of things that could cause slowdowns.

  1. a lot of Express VI.  VI Express is designed to facilitate the installation and quickly start code.  They are not known for efficiency.  FIX: Use the regular functions of LabVIEW such as DAQmx and file write.

  2. you write to a file within the loop.  File writing is usually slower than other functions.  Maybe your hard drive slows you down.  FIX: Use producer/consumer and transfer the file to write to another loop indepdendent.

  3. you build graphics XY in the loop.  Inside that express the VI, it is continually adding more data in the tables stored in the shift registers.  These berries grow, windows must track more contiguous memory to store the data.  Eventually, it would run out of memory.  What size are these graphs?  FIX: Sometimes delete these graphics.  (EDIT: I see that you have the "erase data on every setting turned on for that call.)  This may not be a problem.)

  4. you write to the nodes property of each iteration of the loop.  Changing the properties of controls can be quite slow at times.  FIX: Write to a property node where the properties really change.  True to the visibility properties Plot writing is really bad, because you do each iteration, that it never changes.  You may as well just outside the loop.

  Your code to see how long each iteration of the loop is actually taken from reference.  Turn the pieces to see if you can speed it up.

• error-200279 DAQmx

  Hello

  I read 3 data channels in a chart at a speed of 512 Hz waveform, and my table of waveform seems to slow down over time and eventually stops working, then I get the error 200279?

  ReadSamples.vi
  Property: RelativeTo
  Value: Current playback position
  Property: Offset
  Value: 0

  The task name: AnalogInput

  

  

  I use a structure of master/slave of Manager messages and in my master is the 'reading samples' longer vi which reads 4 samples at a time, when I display 1 channel works OK, but the channels I slow display it gets...?

  Best regards

  Thijs

  Looks like you found a buffer overflow... You are not fast enough reading data in your application.

• error-200279 card USB-4431 DSA

  

  I use USB-4431 dynamic signal acquisition card.  I have the program set out in the attachment.  I am trying to generate a control shaker random vibration signal and at the same time reading back 2 analog inputs. When I run my code with the full program, I have error-200279 but when I split the acquisition & code generation and put it in a stand alone vi and run it in itself, I don't get any errors.  I tried the different sampling frequencies and samples/channel.  one that seems to work best is when I'm 60 kHz and 20Ks/channel sampling.  My requirement is an example for the acquisition of 200 kHz ane 20Ks/channel.  I've been monitoring the node available samples/channel and seems to continue until no more samples are available and it shows 0.  I need to make these 2 tasks to run correctly in the main program, which is an event focused on loops of master/slave.

  Hi ssherian,

  The USB-4431 is a sampling frequency maximum of 102.4 kech. / s. If your application requires a 200 kech. / s, you will have to use a PCI or PXI-based DSA with a sampling rate WAS higher.

  What about the 200279 error, this error is usually due to a problem with the DAQmx hardware buffer. With a continuous acquisition, a good rule of thumb is to have 10 x the number of samples to read sample rate (i.e. the sample rate = 10000 s/s, samples read = 1000). It is also possible that your computer simply cannot process the data quickly enough. If you perform any complex, analysis of real-time data the processor of your computer simply may not able to catch the flow.

  This KB: error-200279 DAQmx Read Error provides an overview of together in-depth to error 200279, possible causes and measures to resolve the error.

  Hope this helps,

• Windows Media Player - no audio during video playback

  Windows media player

  I am running Windows XP.  Windows Media Player opens successfully, I have audio but not video.  I tried to reinstall, update etc.  Still nothing.

  Hi jeffwebs,

  1. did you of recent changes on the computer?

  2 when was the last time it was working fine?

  3. you receive an error message during playback of video files?

  4. What if the problem occurs with all video files read using Windows media player?

  It is likely that the codec is correct / encoder is not installed or is installed but has been corrupted by another program.

  A codec is a software to compress or decompress a digital media file, such as a song or a video. Windows Media Player and other programs use codecs to play and create digital media files.

  A codec can consist of two components: an encoder and a decoder. The encoder performs the compression function (coding) and the decoder performs the decompression function (decoding). Some codecs include both components and some codecs only one of them.

  Follow the steps listed in the section below to download codecs for this problem.

  You receive a codec error message or play audio but video does not play when you play media files in Windows Media Player 11

• MacBook: An error occurred during activation. Try again

  HI, I use MBP and this problem has been persistent for more than 5 months now.

  I'm on El Capitan version 10.11.6. I get the message "an error occurred during activation, try again" when I try to Sign In.

  My Internet speed is ok, ok account password. Already connected to iCloud and App Store with the same password. IMessage + Facetime, I am not able to connect.

  Help, please. Thank you

  Using two-step verification or two-factor authentication?  If so, you need passwords for specific app for FaceTime and Messages.

  Passwords using specific app - Apple Support

  If this is not the case, see this article.  It is written for iOS, but if you translate the suggestions in other similar to OS X, it should solve your problem.

• Unable to sign in imessage: an error occurred during activation. Try again.

  Greetings,

  I just got my board battery and logic changed on the apple store, and since I can not sign in imessage. I get the following error: an error occurred during activation. Try again. I tried to reset the NVRAM, but I still get the error. My internet connection is fine, my e-mail works.

  Thank you for your help.

  Hello

  Open the purpose of this Mac from the Menu of the Apple icon top left point.

  Tab preview is to display the serial number.

  If this is not iMessages will not work (resetting the app just does not this account)

  Return to the repairer and put back it on the logic board (this is supposed to be part of the process)

  If you check it matches what is on your Mac (back, down, or battery compartment)

  If it is 'false' then get his change.

  There is a chance that this has also blocked using Apple ID for iMessages by this computer on the iMessages servers.

  The serial number is used to provide a specific connection of the device.

  IF this does not work after correction or get the serial number to the logic board, you will need to contact the Apple Support (same as Apple Care).

  Once you have explained that it is a matter of Apple ID, he should be free to Fix.  This does not mean that the person of level 1, you talk to knows what to do (they lead script for Apple care issues)

  Ask politely to speak to someone more important.

  Even in this case they may insist on collecting data and hoop jump.

  Based on others who responded that it now gets the engineers involved (the question happens separately the question of the logic board)

  Insist that the server is given regarding the use of your Apple Mac.

  Update or upgrade does not work and neither did a reinstall.

  Even in this case, they can tell you that it could take days for a resetting to filter through.
