Measure continuously and logging LV2014

• continuous measurement and logging, LV2014

  In LabView 2012, I examined how project templates QueuedMessageHandler and the measure continuously and logging (CML). In addition, there are all of a lengthy and detailed documentation for the QMS. There is a much shorter documentation for CML, but readers of mention the QMS, given CML is based on this project template of course.

  I just got LV2014, and I began to consider the continuous measurement and model of forestry (DAQmx) inside LabView 2014 project. There is here a change which is not documented: a state machine additional typedef enum in the loop of paremeter. But there is no change in the QMS 2014 version, while this change is not explained in detail.

  You can direct me to some docs or podcasts more explaining the feature of the new version of CML?

  Also, when I try to run the continuous measurement and model of forestry project (DAQmx), just to see how it works, I see strange behavior: even though I always select "connect" in the trigger section, force the trigger button starts to blink, and two messages begin to iterate through the channel indicator : logging and waiting for release. But I always chose "log" is this a bug?

  I was reading an "interesting debate" since the year last too:

  http://forums.NI.com/T5/LabVIEW/buggy-LabVIEW-templates-amp-courses/TD-p/2298766/highlight/true/page...

  I understand that these models are only starting points, but I'd be very happy for some documentation to understand how to properly use these models (I was quite OK with the original models, but the new ones obtained more complex due to the state machine).

  Thanks for the tips!

  Hello

  The additional Typedef is necessary to ensure that only data acquisition-task is started.
  This is because the mechanical action is defined as "lock when released. For example, when you press on the
  Start button, then release, the changes of signal from false to true, and then it goes from true to false.
  It would be two events. During the first event, a new Message is created. Now, when you take a look at the "Message loop will vary."
  you will also see an additional type of def. In this VI data acquisition task is created and started. The problem now is the second event.
  Now another Message is created to start an acquisition process. And if another task-acquisition of data is started, you would get a problem with LabVIEW and DAQ hardware.
  But due to the fact that in the loop of the Acquisition, the State has the value of Acquisition with the first Message, the second Message does not start another DAQ-task.

  In the QMH there no need of this, because you don't start a data acquisition task.

  Two indicators during indexing, strength of trigger is set to false. If the program connects
  and force trigger is disabled. After the registration process, the flag is bit set to Wait on trigger
  because, as already stated, it is disabled. Now Force trigger is true once again, and it connects again. This process
  is repeated and the indicator is switching between these two States.
  When you open the VI "Loop of Message Logging", you will see that the trigger for the Force is set to false.

  Kind regards

• Continuous measurement and logging model - Hang-Up of may because of the lost output

  The model of continuous measurement and logging in LabVIEW 2012SP1 has a flaw in the Acquisition and recording loop.

  Stop messages manager ignores all messages in the queue of messages. The note says:
  "Stop - empty the queue of all pending messages 'Connect'. Close the reference of TDMS files. "See the picture below.

  This concept breaks if the output message is issued while the Stop message is being processed. The time gap critical to do this is small, because the issue is posted on the front of the queue. But it depends on the treatment in the case of the Manager to stop. Large or small - it can happen.

  The symptom is the application block in an infinite waiting on the queue of message - all commands have no effect, as the rest of the loops are completed. Break terminates the application. Pause button doesn't work anymore. (see this entry forum)
  This problem may appear only after enforcement has become more complex and the schedule has changed - the fresco made model works and does not reveal the question.

  The cure: first of all I thought to preview the elements of the queue before they are scrapped selectively, one by one in the loop to stop, but that usually is not working either, because the output can happen precicely in the laps of time between overview and dequeue - don't forget no outputs are displayed on the front of the queue.

  I think the best option is to replace the flush of the queue in the Stop messages with a selective messages waiting managers one by one and check if the output is - if so, reseat it in the front of the queue. All other messages are discared. That look like this, have seen interesting parts...

  

  Here is the message loop to stop with the problem highlighted.

  As I'm not mistaken, I think it's better that NEITHER updates the model to avoid this problem.

  

  Here is the case of the resting State in the case of stop message:

  

  Us do not hang the CPU run a constant stream of messages ineffective because we only "Log" enqueue messages when we are in the valid state logging (a State of rest here is again a passthrough).

  

  The worst case, it's that there are number of register requests already in the queue when the system shuts down. After receiving the stop idling message, state transitions and other Log messages become non - ops due to the State.

  I consider the opportunity to post a few screws update

• Using the DAQ Assistant. can I create a VI that measures continuously during a fixed time?

  I use LabView to an NI USB-6009 enclosure, with two accelerometers like my analog input. When you use DAQ Assistant to build my VI I have not seen an option to measure continuously for a set amount of time. I need the test to run for two seconds and then stop.

  Is there anyway to specify the exact duration of each test?

  It's about as simple as you can get. Set the number of samples to be twice the sampling frequency (or whatever the multiplier that you want). That's it - a simple DAQ Assistant and nothing else on the block diagram. If you need it to be variable, just wire a control of the number of input samples.

• Should I purchase Measurement Studio and NI-IMAQ separately or NOR-Imaq included in measurement studio?

  
  

  Hi Vjuno,

  Thank you for your interest in Measurement Studio and NOR-IMAQ. Measurement Studio and NOR-Vision are separate software packages. If you are considering comes to acquire, save and display images from a camera IEEE our NI Vision Acquisition software located on our website (http://sine.ni.com/nips/cds/view/p/lang/en/nid/12892). If you want to set up a system of image analysis then you can buy the Module OR Vision Development, this includes NI Vision Acquisition (http://sine.ni.com/nips/cds/view/p/lang/en/nid/2881).

  Thank you for your interest in our products!

• The difference between Measurement Studio and NiDAQmx?

  What is the main difference in Measurement Studio and NIDAQmx. I have a DAQ software, which was originally developed in Visual C++ 2003 M, who initially used Measurement Studio. Now, I want to replace involved studio by NIDAQmx latest version. It is Possible to do?

  Hello

  Measurement Studio is an extension for Visal Studio, which contains a variety of libraries for measurement applications as well as user interface such as graphics.

  DAQmx is the setting for hardware drivers for Multifunction DAQ devices of NOR. If you are using a DAQ card, you need this driver to access with any environment programming (LabVIEW, CVI, C, C++, .NET).

  This means that you can access the material, also with Visual Studio, which has no Measurement Studio installed. Although Measurement Studio is analyze and present the data acquired much easier.

  Hi kwaris,

  "What is the error": well, you use a lot of unnecessary conversions. Really a lot of...

  Why do you convert a dynamic scalar value, then convert to table, then index an element of the array? Why convert to dynamic when everything you needis a simple "build table" node?

  OK, I've included a shift register where you will store your table. It of just a simple 'how to', but not the best solution for all cases. But it should give you a clue...

  Yes.  The network stack is active as soon as Windows is running.  You can prove this by yourself, if you wish, if you can review your summary router network.  It should show the PC in question as being active.

• Folder my documents opens at startup and log on

  Folder my documents is opens at startup and log on how to stop why it behaves?

  See if it works (I'm not your configuration): Command Options Panel\Folder.
  Select the VIEW tab, uncheck the RESTORE PREVIOUS FOLDER WINDOWS at the CONNECTION.

  Here's another option to remove this problem: http://www.technize.com/my-documents-folder-opens-at-windows-startup/.  Make sure that you are in the registry and I would only delete the Documents folder reference rather than all - but it is up to you.  I would like to make a registry backup system and the restore point before starting this procedure to be on the safe side.

  ==================================================================================================================================

  Here is another similar option worth a try, if others do not work (same for system restore point and registry backup):

  Click Start > run Regedit > move > HKEY_LOCAL_MACHINE\ logiciels\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon In RHS Panel, change the value of "Userinit" to: C:\WINDOWS\system32\userinit.exe

  Reset.

  Click Start > run Regedit > move > HKEY_LOCAL_MACHINE\ logiciels\ Microsoft\ Windows NT\ CurrentVersion\ Winlogon In RHS Panel, change the value of "Userinit" to: C:\WINDOWS\system32\userinit.exe

  If this does not work, go tohttp://technet.microsoft.com/en-us/sysinternals/bb963902.aspx and run Autoruns and click all.  You are looking for something, with the documents folder, and when you find it, uncheck the box to prevent it from starting at startup (it probably isn't there because it uses a different process to open it, but it's worth a try since different processes was the one before this one and if you are here it means that you did not).  Check the entire list as there may be several entries.  When you're done, click OK and restart.  The file should no longer start.  If by chance you find explorer.exe listed there, then try disabling that and see what happens.  This can cause a lot of problems, so be ready to CTRL-ALT-DEL and file run Explorer.exe to restart the program and then go back and check the box - it sure is not the solution.

  If this does not work, try a boot minimum http://support.microsoft.com/kb/929135.  If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem.   Follow the procedures described in the article.  Once found, remove, delete, disable or uninstall.  Once remember to put Vista in normal status, as described in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work.

  I hope this helps.

  Good luck!
