What OS is best for LabView Real Time?

Our computer will be dedicated to running a LabView program that will collect and display sensor information on the virtual instrument panel. What OS will provide the most reliable and compatable environment for LabView Real Time?

hi, i wanna ask about win xp, in some posts people says is not suitable use rt on windows because of the difficulty of give priority to certain task over the other ones, i wanna know if i can work just with windows xp or must i use an real time OS.
thanks for help

NI-DAQmx 7.4 Changes for LabVIEW Real-Time

Hello LabVIEW Real-Time and DAQmx users,
National Instruments has recently released NI-DAQmx 7.4. Changes introduced in NI-DAQmx 7.4 provide increased flexibility when performing hardware-timed single-point operations on real-time platforms. The Developer Zone Tutorial: DAQmx Hardware-Timed Single Point Lateness Checking has been created to help explain these changes. Information is also available in the NI-DAQmx Help.
In order to provide these changes in NI-DAQmx 7.4, the behavior of 'DAQmx Is Read or Write Late.vi', used in previous versions, had to be changed. In NI-DAQmx 7.4, the 'DAQmx Is Read or Write Late.vi' has been obsoleted and no longer performs any lateness checking. Applications being upgraded to NI-DAQmx 7.4 are recommended to use one of the lateness checking options discussed in the above tutorial.

Hello,
I changed the program and added a case structure to configure each channel according their type. In order to go through all the channels in the configuration file, I put a for structure.
It seems it is working, however, when I start acquisition, I only see one channel and that is last one which is configure.
Here is the original file, configures all, but only works for AI Voltage:
Here is the modified one:
What I am doing wrong?
Thanks!

How to create RT boot disk for labview real time target

Hi All
I want to use desktop PC as real time target and for this i have to boot this desktop using RT operating system. I tried to use RT disk utilities in TOOLS menu in MAX but at the end it says no disk found in A drive or B drive since i do not have flopy drive in my laptop. I can not make a PC utility USB drive also since this option is not highlighted in the options hence i can not select it. Is there a way to create this RT operating system on a CD drive or can i download this operating system from somewhere so that i can boot desktop PC as real time target. Thak you for your help.

Hello,
Well... you have a problem. : )
The easy solution that i can remember it's.... Buy a usb floppy disk.
Sorry, but it's the only think that i can remember.

Can I use Labview real time with PCI 6013?

How much does Labview real time cost?
Do i need to have some additional hardware to use labview real time with PCI 6013?

You can not use the PCI-6013 board with LabVIEW Real-Time.
We offer three platforms for LabVIEW Real-time. PXI embedded controllers, 7030 data-acquisition plug-in boards (7030/xxxx) and FieldPoint. For more information on these options go to www.ni.com/products and then choose Real-Time from the menu on the left. There are PCI versions of the 7030 boards. Each 7030 board has a data-acquistion board attached to it (6030E, 6040E or 6533). When you embed a LabVIEW Real-Time program on the 7030 you will be able to access the daughter board. You can not access other boards from the embedded program. If you want to use several daq cards in your real-time system I would recommend a PXI chassi and PXI daq boards.

NI LabVIEW Real-Time for Desktop PCs compatibility!

Hello,
I'm pretending to acquire the NI LabVIEW Real-Time Deployment License for Desktop PCs. But before that, I need to be sure that this will work with other boards (not from NI).
Currently, I still don´t have all the project details. But there's a possibility of one board be from other supplier.
Can anyone tell me this, please. It's very urgent.
Best regards,
Paulo Carmo

Hi Paulo,
I guess that you will be disappointed but the response is clearly no.
When you boot a Desktop PC as RT target, it loads with the basic real-time operating system (including drivers for ethernet, for harddrive, memory....). When you want to add drivers on this embedded system, it will be only possible to add National Instruments drivers such as DAQmx, DAQ, VISA ... The possibility to add others drivers (from others providers) is not supported.
Hope it will help you,

How to create a c++ shared library (.so) for linux real time (for myRio) with Eclipse to use in LabView?

I tried already these Tutorials and Advices but I didn't find a solution:

- and some more
I want use c++ codes on linux real time. For testing reasons I want to have a function that adds 2 values and gives the result.
I've done these steps:
1. writing a c++ file in Eclipse (see screensot 2)
2. building a shared library (.so) from my c++ project in Eclipse (with Cross GCC)
3. putting this file on myRio (path: /usr/local/lib/)
4. creating a VI that calls this library from Labview with a "Call Library Function Node" (see screenshot3)
5. Setting the properties for the "Call Library Function Node" (see screenshots 4-7)
After I run this VI i get this error message: LabVIEW: (Hex 0x627) The function name for the ... node cannot be found in the library. To correct this error, right-click the Call Library Function Node and select Configure from the shortcut menu. Then choose the correct function name. (see screenshot1)
I've tried a lot things to solve this problem but I couldn't find a solution. Would be very happy if anyone can help me. I guess that I have to edit my c++ code to export my function (symbol). But I have no idea how to make it. I also tried it with a dll file in the same folder but it didn't help.
Perhaps someone can send an example which works on myRIO.
Thanks!

screenshot7

can see it in the screenshot8 there is a function called "_Z8AddierenddPd" instead of "Addieren". I copied this name to Labview (see screenshot9) and it worked.
I'm sure that there is a way to compile the shared folder with gcc without decorations (mangling). But I don't know how. If someone has a recommendation I would be very glad!
Prepend each function declaration that you want to be available without name decoration with
extern "C" <your function declaration>
Or if you have multiple functions you want to export you can in the header file where you declare your functions simply use:
#ifdef __cplusplus
extern "C" {
#endif
<all your function declarations>
#ifdef __cplusplus
#endif

Is Ardence RTX required when I use PCI-7831R with labview real-time module for RTX target

I am new in the labview real-time field. I want to use labview real-time module for RTX target on only one desktop. My card is PCI-78331R. Is Ardence RTX necessary? Why I cannot find my card in the MAX after I configured the RTX?
Thank you very much.

Hi Ziaozhongda,
You must have the RTX runtime engine installed before the LabVIEW Real-Time RTX module will install. Additionally, you should follow the instructions in the "Using the NI PCI-7831R with the LabVIEW Real-Time Module for RTX" section of Getting Started with the NI 7831R (page 8).
Please see Configuring Hardware for Use with RTX.
Also useful is "How Can I Validate That My PC Will Run RTX?

Is the idea that you will add another CONNECT BY query, using

Do you think that will be better than using ROW_NUMBER?
Will it work if (a, b) is not unique?

Difference entre Deployment License for Standard PC's- ETS RTOS et LabVIEW Real-Time Debug Deployment License

Premier question j'ai develloper suite 2009 SP1.Avec a été fourni le Deployment License for Standard PC's- ETS RTOS sauf que c'est la version Labview Real Time 8.2 Pourquoi ce n'est pas 2009 SP1 ?
Et la deuxieme question est : qu'est ce que LabVIEW Real-Time Debug Deployment License ?
Merci

Bonjour Lunik,
Merci d'avoir posté sur le forum National Instruments.
Il n'est en effet pas normal que vous ayez la version 8.2 du module RT si vous possédez la version de Developper Suite 2010 (qui inclus LabVIEW 2009 SP1). Si vous parlez bien du module LabVIEW RT, vous ne pouvez avoir une version antérieure que celle fournie avec la suite.
Si vous aviez une ancienne version installé, je vous conseille, si ce n'est pas le cas, d'installer tous les modules dont vous avez besoin depuis les disques d'installation de la Developper Suite.
Pour votre deuxième question, je vous renvois à cette page : ici.
Ce logiciel permet de déployer une licence pour faire d'un PC une cible RT.

To develop an VI to aquire data of thermocouples from a remote chamber in labVIEW real time, should use NIDAQ or NIDAQmx?

Hai
I need to develop an VI to aquire data at real time. Am using LabVIEW RT as the OS and i need to know, if i can use NIDAQ 7.0 or should i use NIDAQmx? what is the diffrence between the two? is it just that NIDAQmx makes job simpler?
Also can anybody please tell me, how to access a channel in labVIEW? am not clear about the path to follow to get the physical channel as a virtual channel on the LabVIEW.
I am using a 8186 PXI with labVIEW RT and a SCXI, with both scxi and daq card on the same chassis.
the development will be done on Windows XP which will be the host machine.
Thanx in advance for any answers
Arun

Arun,
DAQmx is our new Data Acquisition driver and should be considered as the primary option when writing new applications because of supportability in the future.
DAQmx does make Data Acquisition tasks much simpler, abstracting many of the board implementation details and giving you a common API for 99% of the tasks you might want to accomplish.
There are a couple of minimum requirements for using DAQmx on LabVIEW Real Time:
- You will need LabVIEW Real-Time 7.1 (or higher)
- You will need DAQmx 7.2 (or higher)
These requirements are mentioned in the following Knowledgebase:
Is NI-DAQmx Supported in LabVIEW Real-Time?
The other thing you might want to make sure of is that DAQmx supports the DAQ hardware you already have or are planning to use. DAQmx does support most of the existing DAQ and SCXI hardware products, and reading thermocouples should become a very simple task.
With DAQmx you can use physical channels, Global Channels (Aliases for preconfigured physical channels, equivalent to the Traditional DAQ Virtual Channels) or DAQmx Tasks (Preconfigured Data Acquisition tasks that include channel, timing and triggering information). A good place to start to learn about these features could be:
Advantages of NI-DAQmx
The following link might be useful to check Hardware support:
http://www.ni.com/support/daq/versions.htm
The driver can be downloaded by following these links:
ni.com -> Support -> Drivers and Updates -> Current Software Versions -> Multifunction DAQ -> NI-DAQ Version 7.3 for Windows 2000/NT/XP
This includes the latest version of DAQmx and our Traditional DAQ driver. Please note that DAQmx base is also listed but that's our Register-Level Programming (RLP) driver, which provides DAQ support for previously unsupported platforms.
I hope this helps,
Alejandro

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?
This is only 8.3% of the available disk drive space!
http://digital.ni.com/public.nsf/allkb/E7E2F5657B6026358625750B007201A6?OpenDocument
National Instrument's solution is either reformat you drive to less than 126GB or replace the drive with one less than that size.
Please NI, tell me you are going to fix your LabVIEW Real Time soon, and that we won't have to wait for LabVIEW RT 9.2.1 in 2011 for this one to be fixed.
http://upload.wikimedia.org/wikipedia/commons/9/90/Hard_drive_capacity_over_time.svg
Drives as large as 126GB or more have been around since about mid 2002. That's about 7 Years now and LabVIEW Real Time STILL can't use drives larger that 126GB! Please NI. Do something.
We deserve fixes to the old versions of LabVIEW RT. How about updates to LabVIEW RT. Such as 7.0.2, 7.1.2, 7.6.2, 8.0.2, 8.2.2, 8.6.2.
We don't need new features or versions of LabVIEW RT such as 9.0 until we have some of bugs fixed in the existing versions.
Kevin.

Coq Rouge (formerly t06afre),
The RealTime OS is an NI Product that is purchased from NI.
NI may or may not outsource design, developement, or manufacturing of the products that it sells under its own Company name.
For this reason I would be concerned if I were a PXI Embedded Controller designer/developer in the United States.
Yes, 126GB is some space. I see that there are now 2TB drives available. 126GB would be 6.3% of a new 2TB drive. Should we all be happy with being able to use 6.3% of the available drive space. Moore's Law seams to be alive and well. Drives larger than 126GB have been readily available for 5 or 6 Years. This should not be a surprise to NI. Why don't they do something about it.
Thanks for the trivia on Bill Gates. I must have missed that one since I don't try to keep up with Microsoft. I believe that he is a wonderful person and he and his family are doing wonders for the world in their "retirement". The world needs more like him.
What I do remember is Steve Jobs telling us that we would never need more that 128MB and that we would never to need to do anymore software development because everything was already in the "ToolBox".

Unable to install labview real-time

I just successfully installed labview v8.0 on a pc and this is my first time to ever use this application. I was trying to install labview real-time v7.1 for my cRIO. Unfortunately, it failed to install. I received an error message saying that I needed to have LabView 7.1 prior to the installation. LabView 8.0 is working great and I dont understand why does LV real-time wants an older version.
Do I have to uninstall LabView v8.0 and order an older version to get labview v7.1 to get running?
Any insights for a newbie will be greatful.
Thanks

What do you mean by "I was trying to install
labview real-time v7.1 for my cRIO"? It is not clear if you got
the error when installing that piece of software in the cRIO RT
controller or when you were installing the software on your PC.
Nonetheless, if your intention is to use LabVIEW 8.0, then there is no
reason why you need to install anything that has to do with LV 7.1
(such as cRIO RT support for LV 7.1 on your PC or LV RT -real-time- on
the controller). In your case, it seems to be ok to ignore errors
related to LV 7.1; it could have been that the computer you are
installing NI software on had an older version of LV that was not
properly uninstalled.
BTW, the installers should be smart enough to install the right
versions you will need given you install LV 8.0 first. To ensure all
needed pieces are installed, make sure you run the installers in this
order: LabVIEW first, followed by LV RT and/or LV FPGA, and NI-RIO last.
Hope this helps.

Hardware recommendation for a real-time camera

Hi All,
We are interested in using some cameras with LabVIEW real-time for some data acquisition. We are monitoring quite a large array of points for on/off signals (so a camera is easier to implement than an array of photodiodes). Our initial spec is a CCD, 640x480 chip and about 15fps. I'm guessing firewire or Gig-E as the interface as I've heard USB is not compatible with real-time.
Our plan is to develop the application to run under LabVIEW real-time on a PXI platform. We also hope to eventually deploy the system so we'd prefer not to use NI Vision (I'm not sure if this is possible or not). Similarly due to cost we'd prefer not to use the Embedded/Compact Vision Systems if we can avoid it.
Can anyone recommend a camera which they have used with LabVIEW real-time? I have no real experience with RT as yet so any advise at all would be a great help.
We are also hoping to deploy the system using a cRIO as the main hardware platform. I've seen real-time cRIOs (http://sine.ni.com/nips/cds/view/p/lang/en/nid/208042) have Gig-E built in. Has anyone used a Gig-E camera directly with one of these controllers?
Thanks for your help,
Dave
