• Assistant DAQ need graphics update during the collection of samples of N

  Hi all, I have a question about the DAQ Assistant. I need to acquire data at low rates (ca 10 Hz). I want to acquire Let's say 100 samples. I join my card day ten times per second. But when I choose N (100) to 10 Hz, updates to the table only once - 10 seconds samples. Is there another way to take samples of N and be able to watch the chart updated 10 times per second the use of samples keep (10 Hz, 1 sample to read) with timer that ends the while loop after 10 seconds?

  When I use the last mentioned way and write data in the file, I always acquire 101 samples, not 100. And I think that's not an ellegant way to write data to file 10 times per second (higher sampling rates, LabView is unable to write all of the samples file .xlsx, with the CT (s) files, it's better).

  Perhaps to collect 1 sample on request would be ok, but so far I have not had an experience with that.

  Thanks for your replies

  First of all, read this excellent whitepaper on the DAQ-mx hardware and stop using the DAQ Assistant, who does not have the flexibility you need to do what you describe.

  Don't you see what you want to do?  You ask to taste 10 Hz and want to update for each samplegraph.  So how many samples do you take before you add the data sampled at the table?

  Now, with the knowledge of what you have learned in the white paper, put some (you can do it in one) features DAQmx to start the Acquisition, in a loop For (with this that connected to N?), take the appropriate number of samples and send that to the table, and then out of the loop, stop the Acquisition.  If you use tasks (created by MAX or using the command 'New task' of the LabVIEW project), you should be able to do this with as little as 3 functions DAQmx (I'd probably use 4) and a single loop.

• The question "Adjust the location of the tab bar" has been closed, but the solution is not satisfactory

  Updates of version 29 on have moved the bar of tabs so that changed the position and function of the address bar. The 'solution' to the question in quotes above is not a solution, the question was just closed. The owner of the issue went back to 95% of the function of the way he had it & has set for that. I find not acceptable and opted to return to version 28. I'm worried, I could have spent the browser after using Firefox since the first beta version. Is there no way to keep the options of version 28 (mainly the position of the tab & address bar) in the updated versions? I tried the Restorer Classic theme, but it did not help. I am running Windows 7 Home Premium 64 bit & Firefox 28 right now without any problem, but I guess that Firefox is progressing certain features on the old version will fail. Help please?

  FJRRider,

  You can take a look at this theme.
  Firefox 2, the theme, reloaded
  https://addons.Mozilla.org/en-us/Firefox/addon/Firefox-2-theme-for-Firefox-3x/
  Large buttons, tabs under the location bar - just above the page content 'window', but the reload and Stop / Go button cannot be moved, however. It uses a combined stop / Go button which could take a volume of little getting used to.

  IMO, much simpler than the Restorer of classic theme and no need to tinker with a large number of settings to make it look 'right', but it has a very limited ability to be changed or reconfigured.

• I want to maintain the "frequency of sampling to report signal frequency" a constant.

  I want to generate sine waves of varying frequencies, say, from 1 Hz to 1 kHz. Sometimes, a swept frequency sine wave. The problem is that I want to maintain the "frequency of sampling to report signal frequency" a constant. That means, the sampling frequency must be 20 or 30 times the frequency of the signal. This should be done automatically. For example, a sweep of 1-10 Hz, if the sampling frequency is 30 Hz at the beginning, it should be automatically updated at 300 Hz as the frequency of the signal reaches 100 Hz. Someone you will suggest a possible solution?

  The basic generating function function has an entry titled "sampling info". It is a cluster and one of the elements is the number of samples. You just need to set this based on your frequency.

  

  I suggest strongly that follow you the course 101 of LabVIEW.

• Question DAQ sample rate

  Hello

  I tried to understand how the 'number of samples' and 'rate' controls affect the frequency of sampling for the DAQ hardware. For example, say I want to acquire data from a sensor of pressure at a frequency of 10 Hz intuitively, I would think everything I do is on the desired sampling frequency, in this case 10 Hz control the 'frequency', try this, I know that's not true. I read that 'number of samples' affects the sample rate by setting a buffer value that must be reached before the VI will process the acquired data. So I also tried to set the "number of samples" to 1 and "rate" at 10, thinking this would have led to a sampling frequency of 10 Hz, and again, it is not. The only way I know to control the sampling frequency is using the wait function (ms), but then I always get buffer overflow errors.

  Can somone if you please explain to me the error in my thought process and also tell me the best way to control the sampling frequency? Is attached a simple VI, I am using to measure my actual sample rate and compare it to the sampling frequency that I am trying to achieve.

  The VI use the DAQ assistant to acquire data of pressure, inserts data into a table, and measure the size of the array. I'm then by dividing the size of the array by the elapsed time in seconds for the sample/s (I'm also dividing the number of iterations of the loop by seconds and using it as a comparison). I compare this value to my entries for the 'number of samples' and controls 'speed' in order to give a sense of the role they play in sampling rate. The VI also allows to choose to use the wait function (ms), as well, using this function is the only way I can control the actual sampling frequency, but then I always get buffer overflow errors. Any information would be helpful, thanks!

  What is the device that you are using? My guess is that whatever you have, it does not allow such a slow pace and is failing at its minimum.

• How to increase the frequency of sampling of several sensors via RS - 485 and writing files of measure?

  I have a vi that:

  -Locate the USB port that RS485 communication device is connected

  -sends a command to each sensor

  -reads a response from each sensor

  -performs a calculation on the answer

  -saves the response to a file of measure

  I used a flat sequence to query each sensor.  I am trying to find a way to modify this vi in order to increase the frequency of sampling on the sensors.  Currently, it takes 2000ms for question 4 sensors and write tot the measures file.  Anyone have any ideas on how to speed up by programming?  I am concsidering on the purchase of a device USB DAQ (USB6000) and rewriting of the vi.  I was wondering if there was some tweek I caould make on the vi.

  Thank you!

  I meant put the time-out on the line, then the reading will be either timeout after 200ms or read the 2 bytes.  Whichever is faster.  Then deletes this 200ms waiting you.  I have attached your vi to show you what I wanted.  I did not notice that it is a hardware or wither then you might want to look in the data acquisition functions.  It will clean up your code and are very easy to use.

• Round the question in Double chain

  Hi all

  I am facing a weird problem in rounded to a value of type double. I thought that LabVIEW always rounds up this rule when the digit is truncated is 5 - round to the nearest even integer number offshore

  When I round up to two points of accuracy, I get results.

  489.335-> 489.33

  489.355-> 489.36

  

  Can someone tell me how rounding works in the above cases? Please find the sample VI (2010) attached, if you want to play with him.

  Thank you

• What happened to the question/problem, that I just posted? You meet serious accidents on your servers that removes messages?

  I can't find the post I recently set up here. Have you had an accident which deleted all recent messages?
  I wanted to write comments to a suggestion that I got here, which was the use of Acronis as a backup manager...
  Manufactured by MowGreen - thank you for your comments.
  But you might have some use of the comment, what I am to do - I actually tried on the backup program you suggested; Acronis.
  I don't know if you have ever tried to restore a backup? You said that you never 'had to' restore...
  I tried to make a backup of my fresh without Norton and all windows and then tried to restore the backup.

  For me, Acronis 2010 ATI seems pretty useless!

  He could not read that a backup of my discs Inter Raid 5 - OK, can be forgiven.
  But he could not read from a SATA vanilla which contained a backup.
  And when I tried the last option to put a backup on a DVD, the program crashed when trying to read the DVD that contains the backup.
  So you better hope that you never have any of your backups - you will never be able to read from this backup.

  On the problem using Windows Update.
  You said that Norton 360 v2 Online is totally incompatible with Windows Vista (or Windows Update?). I am running Windows XP - is the same true for XP?
  Is this true for the Norton 360 Version 3 too? All products current Norton is not compatible with Windows?

  Here is the text that has been deleted on the Forum server:

  More effective than a virus - KB930494 MS update ends with true Msg that Windows cannot now work correctly

  I started to reinstall Windows XP, after he has screwed up and I discovered that all the system snapshot
  I created backups worthless - MS removes automatically after 90 days...

  But when reinstalling Windows XP Pro MCE 2005 I managed to beat or dodge the many problems - like all the
  famous error when update .NET Framework 1.1 Service Pack 1 and many others
  Suddenly I met an error generated by Microsoft of NONRECOVERABLE type!

  While trying to install Windows, I agreed that Windows was full of bugs and security flaws and
  need a large number of fixpacks installed via Windows Update.
  Such a group of patches is called KB930494 and the full name is:

  .NET framework 1.0 Service Pack 3 SYSTEM. WEB. DLL and MSCOREE. DLL Security Update for Windows XP Media Center Edition and Windows XP Tablet PC Edition

  Windows Update gave a brief error msg that this update has failed and I have tried to run this update
  manually when it produces the following error message: (note he's telling the truth when it)
  claims that "Windows may not work correctly")

  ---
  KB930494 Setup error

  Error while updating your system.
  Windows XP has been partially updated and may not work properly.

  Ok
  ---

  So, this update of Microsoft killed my system - it sure that _ 'does not properly"more.
  Lots of things off, lots of BSOD...

  Og - of course I should have used the system restore and created a backup that I should come back...!
  I did well - but this bomb of viral type of Microsoft made sure it was not possible to create
  a valid system by restoring such a backup. Probably because half the file system matches the other.

  The worst part is - even if I try to reinstall Windows again, avoiding this Virus created by MS, how can I be sure that
  This will be the only disguised bomb nothing extraordinary provided by Windows Update as necessary security patches?

  So guys, what is the best utility backup/restore partition there?

  Thank you for your response.

  I didn't know about the log file, but watching her (she is very large) it seems is it can only be useful to those writing or working with
  updates...?
  You want to send me the file here? (Probably too big). Or you want I send you the file to watch?

  Only say unique error Code I find gives the following:
  Windows XP has been partially updated and may not work properly.
  29.641: Update.exe extended error code = 0xf070

  Interesting piece of info about security SW, because I have Symantec Norton 360 v2 online riddled with bugs, but I'm not
  optimist that disable Norton 360 Windows Update would do the trick, especially since I had so much
  problems with most of the time updates .NET Framework - it seems that this Windows component is full of problems...

  On the question of the "order of Installation" I initially let Windows Update handle this the way he wanted to.
  After that giving the briefest mention that only KB930494 had failed, I then tried to revive this one update.

  Do you think the system can be restored using the REPAIR, or whatever, or I have to reinstall all windows
  from scratch?

  Kind regards

  Ben,

  There is no need to send or post the log, because the whole .NET updates installation and OS stability problems are caused by Norton 360.
  Suggest you clean boot Vista as being expected to eliminate all processes and services of Norton to interfere with the installation of the update.
  In fact, you'd be much better off dumping Norton 360 and installing a Windows-compatible antivirus software.
  Then launch their removal tool for Norton ensure all remnants no longer stay or run this tool (AppRemover) as she removes a long list of security products.
  Then download and install one of the free AVs that work well with Windows Vista, Avast or Antivir .

  You can probably repair the OS running sfc/scannow from an elevated command prompt .
  If that can't do the job, then perform an upgrade on the spot .

• Is it dangerous for the HARD drive, the icon she samples D:\?

  Is it dangerous for the HARD drive, the icon she samples D:\?

• Is it possible to achieve a high level simply by means of raising the question threads?

  I just noticed a question posted by a person at a level 6-8, with more than 10 k points... and somehow the question wasn't form, standing that I expect in general that points up.  A quick glance suggests recently a large number of debates question raised and rare if no answering other questions.  I can't view the earlier story of how the points were won.  And most may indeed have been won answering the question on the other.  And somehow, I care little.  But is that what we are overemphasizing points for raising a thread that says: 'how to... '. » ?

  It's just a thought.  Maybe a confession that I sometimes pay a glance at the 'level' to answer questions; I am also aware that even the great guru can be in the "level 1"!

  Not necessarily by simply asking questions (Yes, some points are awarded, and lower levels of status do not require a lot of points to get through them), but it can also be that the person really is (it may be a surprise) marking answers as correct and useful, that rewards the further.

  So, Yes, a person can certainly win first levels quite easily by simply asking questions, as that shows they are involved, but does not necessarily mean that they are any kind of expert in the field.

  If you look at the profile of people and then move to their reputation, you can see how they earned their points; and if you see someone who appears to be games/abuse the system by simply stocks that give them points without really contributing, please feel free to raise them up to the admin who will take a look and deal with them if necessary.
