Mesures simultanées fréquences (labview 2010)

Bonjour,
je développe un programme dans le but de faire de l'analyse vibratoire. J'utilise le matériel suivant:
-châssis NI-cDaQ 9188
-une carte NI 9234 pour l'acquisition des données provenant des accéléromètres (4 accéléro)
-une carte NI 9401 pour la mesure de fréquences (2 fréquences). Je récupère mes fréquences à l'aide de compteurs.
Pour l'acquisition des données provenant des accéléro, aucun soucis.
En revanche, pour les mesures des fréquences, ça va moins bien.
J'ai testé 2 solutions:
-la première, je crée 2 tâches dans le MAX que j'appelle sous labview (cf. vib 5.jpg), dans ce cas, j'ai le message d'erreur suivant pour la 2ème tâche: "Le périphérique ne peut pas être configuré en entrée ou en sortie car des lignes ou des terminaux qui lui sont connectés sont utilisés par une autre tâche ou une autre connexion. Cette opération nécessite que toutes les lignes et tous les terminaux soient temporairement réservés à la communication, ce qui interfère avec l'autre tâche ou connexion."
-la seconde, je crée les tâches directement dans labview (cf. vib 5.jpg), ce qui semble fonctionner. Mais dans ce cas-ci, c'est à l'analyse des résultats que je constate le problème.
je voudrais faire un enregistrement simultané des données provenant des accéléro, et de mes 2 fréquences. L'enregistrement des données provenant des accéléro prend en moyenne 2 secondes. Je voudrais donc pour mes fréquences (NH et NL) enregistrer 200 points, répartis sur 2 secondes pour que l'analyse soit cohérente. Or, j'enregistre bien mes 200 points, mais a priori très rapidement, ce qui fait que lorsque je trace mes courbes, j'observe des paliers et non une évolution continue. De plus, je suppose que les acquisitions de mes 2 fréquences se font successivement.
Y a-t'il une solution pour que je puisse faire tous ces enregistrements simultanément?
En vous remerciant d'avance pour votre aide.

Bonjour,
et merci pour votre réponse.
j'ai fait le test que vous m'avez suggéré, mais malheureusement ça ne fonctionne pas.
De plus je n'arrive toujours pas à obtenir une acquisition continue de mes fréquences, il me manque des valeurs (cf pièce jointe).
En espérant trouver rapidement la solution.
Merci

LABVIEW 2010 erreur 1502

Bonjour,
J 'ai créer un VI qui tourne sur Labview 2010, je souhaiterai créer un (EXE) avec application builder que j'ai à l'essai encore un mois.

Bonjour,
Finalement le problême vient d'un vi express, impossible de créer un exe avec le vi express "écrire dans un fichier de mesures".
Je l'ai supprimé et j'ai pu créer mon exe.
Est il possible de remplaçer ce vi express par autre chose ?

Problème création .exe avec des VIs Expresse (Labview 2010)

Bonjour,
Actuellement en stage j'ai été chargé de créer une interface. Tout c'est parfaitement déroulé jusqu'à ce que je doive créer l'exécutable. En effet l'erreur 1052 se produit lorsque je souhaite créer mon exécutable. D'après ce que j'ai pu lire sur les forums ceci est du au passage de Labview 2009 à Labview 2010. N'ayant que Labview 2010 comment puis-je créer mon exécutable en conservant mes VIs Express ?
Si je ne peux pas conserver mes VIs Express par quoi puis-je les remplacer ?
J'utilise les Vis Express suivant : Ecriture et lecture d'un fichier de mesure et construction d'un tableaux.
Merci d'avance,
J-R
Résolu !
Accéder à la solution.

Bonjour,
Il vaut mieux ne pas utiliser de VIs express pour faire un exécutable.
En ce qui concerne les fonction Ecriture et lecture d'un fichier, tu peux utiliser les fonctions Ecrire dans un fichier au format tableur et Lire un fichier au format tableur. En ce qui concerne la construction d'un tableau, tu peux utiliser la fonction Construire un tableau.
Cordialement.

I tried another machine, 64 bit of course, as I want to deploy my application on a 64bit PC, but still got the same problem.
This other machine was from HP, iCore 3 (4 CPUs) 2.2GHz, 4GB RAM and running Windows Professional 64 bit.
Now as I see it, it could be a Run-time environment mis-match error.
For this I tried installing a 64 bit LVRTE from NI, but still no sucess.
I checked DEP, for all 3 PCs and it was set to the following
Turn on DEP for essential Windows programs and services only (first option).
I am confused. I can not find a solution for this and it is really frustrating.

But I am assuming that when I make the installer, the 32-bit Run Time Engine is appened with the installer, as show below
Since from the picture you can see its including the support installers from '\Program Files (x86)\'
The application runs queries to fetch data from database in SQL server 2008, and for that I am using a Microsoft SQL Native Client 2008 R2 64 bit ( this is the only version that installs on either PC, even the one on which I developed my LV Application).
I am not using any driver, only toolkits for reports - and for that I un-checked the "Remove unused polymorphic VI instances" when making the executable, otherwise LV throws up an exception that share variable are not being included.
Yes I did reboot every time after I ran the installation.
Still getting the same error.

Run-time engine problem in Labview 2009 and Labview 2010

I have a problem with Labview 2009 and Labview 2010. I updated my Labview 2009 into 2010. But it turned out to be a trial one, because i did not have the serial number. So I uninstalled the Labview 2010. however, the funny stuff came over. I cannot use my Labview 2009. So i uninstalled Labview 2009 again. But eventually, I could not reinstall Labview 2009. Every time i had a runtime error and i could not proceed with the installation. in addition, any installation related to Labview is not permitted and the same error came up every time. it is very annoying.
So, What is the deal?
I attached the error here. Any comments or advice are welcomed and appreciated.

By chance is this machine's language set to any non-English locale? You would check the locale setting by:
Opening Control Panel.
Opening "Regional and Language Options".
Looking Under "Regional Options" >> "Standards and Formats"
If it is set to something besides English, trying setting it to English and please report back what locale it was set to (or if this even solves the problem).

How to configure LabVIEW 2010 to communicate with GE Speedtronic Mark VI ethernet global data (EGD)

We want to use LabVIEW 2010 to send/receive floating points from LabVIEW 2010 to/from a network (192.168.101.xxx) that utilizes GE ethernet global data protocol (EGD).
The network has several HMI's running Cimplicity Plant Edition 4.01.
We can configure Cimplicity to read modbus points from LabVIEW using LabVIEW's multi-variable editor and a modbus slave library.
However, we cannot get the points from LabVIEW to read/write to the EGD protocol. Anyone ever run into this?

EGD is a UDP message (port 4746h) with a special header.See below for header structure (32 Bytes). Send UDP at constant rate. Limit user data to 1400 bytes. If you want to receive EGD data don't forget to increase the MaxSize connector on UDP receive to 1500. Are you using the a csv file or SDB Server to get tag names? Or manually entering tag names in cimplicity? This works much better than OPC because all parameters are contained in your labview executable. If you have a redundant cimplicity HMi Server send as Broadcast to the local subnet. All consumers will get the EGD telegram. Example IPA of 192.168.0.255. Server 1 IPA 192.168.0.1 and Server 2 IPA 192.168.0.2
Maybe to late for this project but would be a good upgrade or the next project.

No longer able to import CVI Instrument Driver in LabView 2010

Hello,
I used to be able to download the Import CVI Instrument Driver Wizard in LabView 2009, but there is no wizard for 2010?
I also tried importing the driver with the shared library import, but then Binary, Slides and Rings do not come up with their values i.e. if my slide in CVI has 3 positions :
Description      Value
Item 1                 1
Item 2                 2
Item 3                 3
or if my Binary has
Description      Value
On                        1
Off                        0
they do not import the description into LabView 2010?
I tried copying the directories created by the 2009-wizard to the directories of 2010 i.e.:
from     C:\Program Files\National Instruments\LabVIEW 2009\resource\CVIFpConv
to          C:\Program Files\National Instruments\LabVIEW 2010\resource\CVIFpConv
and
from     C:\Program Files\National Instruments\LabVIEW 2009\project\_DriverCtoLV
to         C:\Program Files\National Instruments\LabVIEW 2010\project\_DriverCtoLV
and the wizard loads and runs until I specify a .fp file and then I get the error in the jpeg attached. When I try to open the block diagram (FC_RFL_Initialize.vi), it says you need a password to view it, so that stops my debugging.

Is it possible to disable the optimized compiler in LabVIEW 2010

Hello,
I have a project that take 3 minutes in LabVIEW 8.6 to build and now with LabVIEW 2010 it take 10.5 minutes. 3x more longer.
In fact my project as 61 .lvproj for a total of 4300 vi's that take 1 hour to build. If I interpolate, the entire build process will take 3 hours in LabVIEW 2010. This is not acceptable
I know that the new compiler optimize the code for better performance, but if I don't need better performance.
Is it possible to disable the optimized compiler in LabVIEW 2010 with an INI key in LabVIEW.ini.

One Application Builder setting you might try out to make builds go much more quickly is the Remove Unused Members of Project Libraries checkbox and the Modify Project Library File after Removi....
This can drastically cut down the build times. Note, however, that this option does not work well if your application will load external plug-in VIs when it runs, because the libraries of those plug-in VIs may conflict with the modified libraries in the executable file. If you don't have a plug-in architecture, this will not affect you.
The "Remove unused members of project libraries" was already selected but not the "Modify project library file after removing unused members" and selecting this cut the build time from 10.5 min to 4 min.
Thank you Jarrod for this tips

Building App Gives Error 6 about 50 - 80 - 99% of the time. Windows7, LabVIEW 2010 SP1

Hi
First off here is a link to a discussion of the problem. http://forums.ni.com/t5/LabVIEW/Error-6-occurred-when-building-an-Executable-in-Labview-2009/m-p/997...
I have tried all the suggestions on this link with no luck.
Background: have been using LabVIEW 2010 without problems since Sept, then I started getting the error 6 with the following message.
" Error 6 occurred at Delete in AB_Engine_Delete_Internal_Files.vi->AB_EXE.lvclass:Build.vi
->AB_Engine_Build.vi->AB_Build_Invoke.vi->AB_Build_Invoke.vi.ProxyCaller "
This started on one project and is now occurring on another project. Sometimes it builds 50% of the time, other times I can't get it to build at all. I have upgraded to SP1, no change.
Here are some things I have tried.
Moved build directory to c:\a
Renamed project, moved project right under c:\
Disabled Google , disabled Win indexing, disabled Win7 user acct. Control, run LabVIEW as Admit all the time, win explorer closed
mass compiling, closing the project, closing LabVIEW, re-booting
Unistalled LabVIEW 2010 SP1 and re-install, twice.
I believe I rebuilt my project in a new project.
I moved my projects to a WinXP system laptop I have, and they never get Error 6 ! Short term fix, but I have to use Win7. So I hope this means it is not my code.
The funny thing is that this is totally random. The unfunny thing is having to explain to a client I can't get my code to compile during a frustrating 95% of the time failure episode, yikes!
Any help and suggestions would be welcome.
BTW, the next step is to totally uninstall LabVIEW with a 'special' procedure and piece of code sent to me. Don't want to, but am really at wits end. Also waiting to hear back from my service ticket, but am desperate to have parallel solutions to try.
Thanks
Mark Ramsdale

Thanks for the clarify.
I also meant to post this link. It has a lot of info, this is the link I tried most if not all of the suggestions for.
http://forums.ni.com/t5/LabVIEW/Get-Error-6-about-50-of-time-when-building-Application/td-p/1242634
By the way, I was told that uninstalling LabVIEW will not resolve the issue, dodged a time killer :-)
It seems the error is caused by Win7 and file reserving. Waiting to hear back on that. Have an SR.
Again, any suggestions welcomed, maybe some Win7 ideas from those who know more about it.

Labview 2010 run-time engine silent install

I am having trouble with installing the run-time engine for LabVIEW 2010 with the silent option.
I am using the minimum version of the run-time engine.
Before I used the LV7 run-time engine. Then I could install it silently using LVRunTimeEng.exe /qb!
In LabVIEW 2010 the run-time engine is no longer a single file but a directory that contains the installation files. There are two files that can be used to launch the installer Setup.exe and LV2010runtime.msi.
Setup.exe does not seem to accept any command-line arguments. LV2010runtime.msi however accepts the command-line arguments and can be installed silently.
Now my problem is that I am building a windows installer using a third party application and it is only possible to launch exe files after the installation completes. Before I could launch the LVRunTimeEng.exe /qb! to install the labview 7 run-time engine but now when I have upgraded to labview 2010 I cannot do the same for Setup.exe.
My question is if it is possible to use the Setup.exe file to install the Labview 2010 run-time engine (minumum) silently?

Setup.exe runs a number of other .exe files during its execution. This article looks like it will allow you to run setup.exe silently by supressing all messages and windows:

Hi Susheel,
RFC module interface parameters (import, export , tables) can only refer to data dictionary types. Hence if you currently have one of the parameters referring to a type defined in your function group main include or in a type pool, you need to create a SE11 data dictionary structure/ table type for that and then change the data type reference.
Cheers,

How to get Point Grey Dragonfly firewire cameras to work with LabVIEW 2010

We recently got a new computer. The O.S. is Windows 7, 64-bit. It has LabVIEW 2010 (also 64-bit) and the Vision Development Module, as well as the Vision Acquisition Driver. We also have Point Grey Dragonfly Express cameras. The first trial of using LabVIEW to get images from one of the cameras yielded greyscale images (they are color cameras). We then installed the Point Grey drivers (flycapture2.1.3.4_x64). After installing the drivers, the camera was is no longer recognized in MAX. Does anyone have pointers or advice? Thanks.

It's been a bit since I've messed with camera settings. But I think LabVIEW requires the NI-IMAQdx driver and the greyscale was from not setting the bayer filter. I can't poke around my camera settings right now, so I can't double check.
