• Why the continuous measurement and Logging in LabVIEW 2012 Project uses strings instead of Enums and orders from the queue?

  Hello!

  I noticed that the continuous measurement and a project in LabVIEW 2012 Logging using chains instead of enums and orders from the queue. I wonder if there is a good reason for it?

  Kind regards

  Anguel

  First, string vs enum debate is probably the version of LabVIEW vim vs emacs. There are good arguments on both sides, and I doubt that there is always a "winner".

  A brief summary of our reasoning for the current state of the project examples:

  1. We used enums for the state machine because it is self-contained. A state machine will never tell himself to enter a State, he does not know. Knowing (as the programmer) all possible States with the help of an enum allows you to enlist the compiler in order to help us avoid mistakes to change the time (because you can't quite out an enum and LabVIEW can be said if you are not covering all cases to a structure of the case, etc..).

     Enums provide greater protection and rigidity by ensuring all withdrew at the time of publishing. This is often the 'default' recommendation that we do.

  2. We used strings for messages in queue manager because the producer of message and the message handler could be independent processes that are reused or traded. Channels avoid the need for the compiler to be able to connect the orders and push this responsibility to the programmer. This allows you to develop some sub-components independently as long as you agree to a series of channel commands that you can manage - you need not to share a file 'messages.ctl' or 'states.ctl '. It is conceivable a loop of message management a message it does not, how you can decide to either silently ignore it or will trigger an error (as we do in the model). The strings make it also easier if you want to swap the queues of LabVIEW outside by a TCP implementation for network vacilitate or intra-Processuse communication where the other end may or may not be written in LabVIEW.

     Channels to provide more flexibility (that is, you can add new commands to an existing via plugins system, you can pass parameters as part of the string, etc.) at the expense of pushing her potential errors at run time and to put more responsibility on the programmer.

  3. The actor's gifts frame a 3rd option - using classes such as messages. For me, it combines many of the advantages of these two enumerations (strictly typed, change errors) and strings (flexible and scalable), but with the disadvantage of being somewhat less transparent (you understand OO, be comfortable to navigate through a multitude of screws, legacy of understanding, etc.).

  I don't know there are other reasons, others to the breast OR had or seen as we validated models and examples of projects in-house, but here are my reasons. We know that we can not design for each situation there - our goal is to get useful models against new users to make them aware of what well thought LabVIEW programs are similar to experienced users know their applications better and I hope they do not hesitate to change what we provide or create their own designs, when they feel it's necessary. (On a side note, please share what you come up with - a community of experts sharing models would be really useful to us all LabVIEW users).

• 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

• 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

• Continuously measure and write waveform using PDM

  Hi all

  I'm doing my thesis by using Labview 2010 (since this is the only version currently available in University ). I need to read and save data from the microphone (currently to simulate a signal because I need to make the program work first) then save and analise IT (has not reached this point yet). I tried to use the structure of the event in order to record and then play tdms files. But unfortunately it saves only a small piece, then I inserted while loop, so it will record continuously but the program is not responding after registration, I push and I can only manually close the toolbar it. Please does someone could help me or suggest that something since I'm not very good for Labview and any comment is welcome. Here's what I've done so now. I tried searching forums for a similar solution but did not find anything useful (some had a much newer version so I could not open). Thank you.

  Hi and welcome to the forums,

  The reason why you can not stop the waveform recording or exit the application is because you have the case of the events set to "lock the table until the end of the matter for this event" (in edition events). This means that LabVIEW will not respond to the user until the end of this structure of the event, but because you have the option to press the while loop stop to complete the structure of the event means that you have a blockage and abandon the VI.

  The architecture of your application is not ideal - I highly recommend everything that takes a long time to execute within the structure of your event for the above reason (obviously you can uncheck lock as a quick fix Panel). I think I have a look at the design of producer/consumer model (events) (new... > model > frameworks) because it would be more appropriate for your application. You can manage your button presses in the structure of the event and have a state machine in the loop at the bottom for starting, running and stopping of your data acquisition.

  The idea is that you don't do very little inside the event structure so it frees up the façade, but the messages (e.g. power acquisition data, quit the application) are managed by another loop.

  I don't know if it comes in LabVIEW 2010, but there are examples of projects that include a project in 2012/2013 "continuous measurement and logging" which may be suitable for your application. There are also examples of the State machines and managers of messages queued.

• How to install the spectral measures and Modulation for several versions of Labview Toolkits

  
  

  Hello dear,
  This is a known issue. You can read in the readme of the modulation toolkit:

  Two Versions of LabVIEW installed
  The installer supports the installation of the Modulation Toolkit into one
  version of LabVIEW; installation of the tool in several separate
  facilities (e.g. LabVIEW 7.0 and 7.1 installed LabVIEW LabVIEW
  on the same PC or in separate directories) is not supported or recommended.
  A way not supported to do but involves manually copying files from
  one LabVIEW installation to another. To do this, you can install the
  Modulation Toolkit to the base of a LabVIEW installation directory, and
  then manually copy the files installed in the other installation of LabVIEW.
  The following list includes files and relevant directories. Copy all the files
  These directories, including subdirectories, using the equivalent
  paths related to the House LabVIEW directory for the target.

  \vi.lib\AddOns\Modulation\*.*
  \vi.lib\AddOns\NISML\*.*
  \examples\Modulation\*.*
  \resource\objmgr\NIMTAttribs.RC
  \resource\objmgr\NIMTAttribs.RCH
  \help\lvmod.txt
  \help\lvmod.chm
  \help\lvdmt.txt
  \help\lvdmt.chm

  Note that this list does not include installed files. Also, copy
  the files in this way is not equivalent to a complete installation in the
  another version of LabVIEW. Especially own error text to the
  Modulation Toolkit will not be updated and the example Finder ads will be
  the examples of Modulation Toolkit.

• the continuous reserve and the sticky timer

  Hello

  Imagine the following configuration:

  Timeout 10

  Serverfarm serverfarm_A

  Serverfarm host serverfarm_A

  Book server1

  Book Server2

  This standby

  the continuing standby command performs the following:

  • Tears down connections existing non TCP on the server

  • Allows current TCP connections complete

  • Allows new sticky connections to existing server connections that match the entries in the database in post-its

  • Balance the load all new (other than the above sticky corresponding connections) connections to other servers in the farm

  • Finally takes the server down

  I have a question for "Allows new sticky connections to existing server connections that match the entries in the sticky database".

  Connections that match an entry in the sticky database sticking them to server2 will be delivered to server2.

  What happens with the meter of "time-to-expire? The time-out value for the entry of post-it on the server "continuous standby" will be reset and restart with the configured time-out value?

  I find no answer in the documentation for this issue. If the counter is reset even when the book is development in standby, then it is possible the book will ever 'empty '... (especially when the value of timeout is for example 24 hours)

  Current - now we must import new recruits and assign the correct model

  Want - when a user is added to a security group in AD, so when CUC doing his nightly sync, it automatically import user and assign a preconfigured for the account and all user model is automatic and I have never import it back these users.

  At the present time the course help desk users are already imported via LDAP and have the role that was.

  Suggestions?

  Not something that the UCA can do out of the box.

  The UCC does not offer, is to do the LDAP synchronization and once they are in CUC, to import, choose the model.

• Synchronize the analog continuous entry and continuous analog output using the unique PCI6024E data acquisition card

  Hello

  I want to generate the continuous signal and at the same time I want to read that signal that I generate using a single card DAQ. I want to generate signal and the received signal is synchronized and in phase.

  I looked at several samples on the sync, but it quiet confusing. One using the same clock of entry while the other use a trigger to start. I use the PCI-6024E DAQ card.

  Can someone help me in this regard?

  In two of these screenshots, the task to HAVE started first (that's what you want, because it is the task of the slave).

  Typically for AO, you can simply write a unique period of your waveform, and then regenerate again and again.  Your waveform would be preset before the task starts.  If you need to update the waveform on the fly according to enter programming during execution of the task, you would disable the regeneration.  In addition, if the wave form is such that it cannot be easily represented by a predefined buffer (for example, it is a strange frequency which is not a same ditch at the bottom of the sample clock), then non-regeneration is the way to go.

  Best regards

• the mouse pointer and cursor of dysfunction, cannot type, cannot connect to my user account?

  OK, I'm not sure how succinctly describe the problem since it is composed of so many things that have actually made my computer useless. I think it's a virus, but my virus scan did not come with something useful, so.

  Last night I watch Youtube videos and edit some pictures when I noticed that I had to type on the touch pad repeatedly until the computer responded. Then it stopped working completely (IE I could still move the mouse pointer, but couldn't click using the touch pad). I switched from windows to look for a solution on the internet, but when I clicked on the address bar of Google Chrome the cursor started ahead of his own, as someone has pressed the space bar - but I was not. This makes type impossible because there were huge gaps between each letter. I turned the computer off and back on (thanks, ICT courses), but the problem has not disappeared - only now, the mouse pointer disappeared sometimes still. It was getting late so I turned it off again and fell asleep.

  This morning as I began it upward there was noises Eman that makes it usually when I plug / unplug power. I tried to type in my password... and couldn't. The capslock wasn't on, I of course did not forget the password from one day to the next, but I kept receiving error messages and could not open a session. Even worse, when I tried to switch to an account that was not protected by Word, he kept jumping to the mine after maybe 3 seconds. I finally managed to click the icon of the second account and logged.

  The touchpad still don't click, when I open Chrome and clicked on the address bar he reacted as I clicked with the button right referring (so I couldn't type) and the mouse pointer always disappears randomly. I did a Norton quick scan and it came with 22 'risks' that he apparently 'fixed', but the problem has not yet disappeared. I would be v. grateful for a quick response, as the laptop is actually not mine, but my father (who keeps valuable most of his photographs on the hard drive).

  EDIT: I opened it in Mode without failure. the touchpad works now, but randomly on the keyboard keys have stopped working. Others come with a random combinations when I press on them, for example. "you" instead of "t", "p"] - when I press on «-» I can't even reinstall the keyboard drivers, because I can't type in my admin password.

  Also I do not know what topic to put this in so if it's wrong, please let me know!
