Desktop PC as LabVIEW Real-Time Target and DAQ ISA card

I want to use LabVIEW Real-Time (Desktop PC + OS Pharlap ETS) for operation with DAQ ISA card.
Pharlap ETS supports operation from Windows dll and can supports Third Party Device PCI.
Whether there is a possibility to work with ISA card in Pharlap ETS?
I want to work for example with card PC20TR from BMC Messsysteme GmbH.
Does anyone have tricks for using ISA card in Pharlap ETS?

Hi,
If you have reviewed the requirements for a Real-Time target and verified that your computer is compliant you might want to check out this article. The main issue that people encounter when using PC's as RT targets is have the correct network card. Make sure the card you have is on the supported devices list on the webpage that Christian posted. You should be able to develop a driver using low level VISA commands but it is not an easy task. Read over the developer zone article to learn more about it.

How to install Vision run-time engine to a desktop PC converted to real-time target

Hi, all
I don't know how can I install the vision run-time engine to a desktop PC which I converted to a real-time target. The same problem applies to installing real-time run-time engine and labview run-time engine to the real-time target. The only way to install software to real-time target is through "add/remove software" in MAX for remote system, but it is not for all types of run-time engine installation.
I am also confused about how to activate those run-time engines for the desktop PC as real-time target.
Please help and great 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.

Read CPU temperature of Desktop PC running LabVIEW Real-Time

Is it possilbe to read the CPU temperature of a Desktop PC running LabVIEW Real-Time? I found an older example that allows to read the temperature of PXI systems (http://www.ni.com/example/29538/en/). Is there a possibility for Desktop Real-Time Machines as well?
Regards,
Steffen

Hi this is heavily dependent from your specific Hardware. Which PC or more specific which main board do you use?
I found several examples in the NI forum that try to access the CPU data.
I’m using a Dell machine and both temperature VI’s are not working for me.
Hope you have more luck.

VI Server in the real time target and Vi client under the local computer

Hi,
In my project i want to make a data communication between a vi server which is runnig in the real time target and a vi client runs under the local computer (My Computer target).
My problem is when i Click the property terminal of the property node function (located on the Functions>>All Functions>>
Application Control palette) , i don't find the front panel open option from the shortcut menu.
Thanks.

The Front Panel options are methods. Try dropping an Invoke Node down instead of a Property Node.

End of memory. Labview + Real time module + Compact Field Point 2120

My name is Michele Ciampichetti, I'm writing from Italy.
Frist of all, excuse for my english.
This is my first experience with Labview, and the application is not so easy. We use Labview 8.2.1
Our system is costituited by two different parts: there is a Compact Field Point 2120 as remote target whit some I/O card, and a PC used to releave data and memorize them (host).
The comunication between the two targets is performed by ethernet lan with Shared Variables not bufferized and not real-time fifo.
The problem is this: the sistem requires a big number of Vis and Variables (about 20 Vis per target and 50 variables localizated in 5 different librarys all in the remote target), and it should store data, acquisited by the FieldPoint, on a database (SQL Server 2005), one time per minute. This storage is made by Labview Database Connectivity Toolkit, and it work correctly. The problem is an excessive consumption of RAM on the PC.
The question is this: The use of many shared variables or vis, bring the memory to always grow? I try to explain myself. When we start our application, after the first minute and registration on the database, the memory grow of approximately 1,3 Megabytes. This is repeated every minute, and after approximately two ours, Labview break down and display "Not enought memory".
We look the on-line help for one solution, and we have found that the variables (local and shared), the concatenate funcion, the array and Vi indicators copy in memory their older value when updated. Is possible that this is the cause of our problem? There is a method to avoid it? How labview uses memory? It is possible set it up for not maintain older value in memory?
We need to run the application up to 4 days for complete its work, is a long test for a climatic room.
We're looking forward to hearing from you.
Best regards
Michele

centerbolt is correct, you can't load a .exe or even run a program on the fieldPoint controller unless you have the Real Time module. However, that does not mean you can't use your FieldPoint bank without the Real Time module.
From LabVIEW for windows you can make calls to the fieldpoint IO using the fieldpoint read/write functions.
This program runs on the PC not the FieldPoint controller. If you loose network connection to the fieldpoint, your program will loose connection to the IO. For many data logging applications this type of arrangement can work just fine. However, if this is the only type of application you are ever going to run, then you may as well not buy the Real Time controller for your fieldpoint but the network controller only.
If your application requires more reliability, and/or greater determinism than can be achieved by running a program on windows, then you should use the LabVIEW Real Time module and develop a program that can run down on the FieldPoint controller independent of windows.

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.

NI is not making the Real Time OS in house. I do not remember which firm that is making it. Anyway you are allowed to use a hard drive that has been partitioned. And 126GB is some space is it not?

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".

Could I use two regular computer to achieve realtime communication using the Ethercat and Labview Real Time Module?

Could I use two regular computers (one acts master , another one acts as slave using the Ethercat Internet Card) to achieve realtime communication using the Ethercat and Labview Real Time Module? if it could, what hardware should I purchase from the NI ?
Thank you!

Hi Xiaolin,
NI doesn't offer Windows based Ethercat master or slave software. Only LabVIEW RT can run the Ethercat driver.
However, you could use a LabVIEW RT target as an Ethercat master and use the Ethercat Internet Card with a slave PC (note: I think this will work from the Beckhoff description of the card you are describing. The card should integrate like any other non-NI slave. However I haven't tested the setup and don't advise saying it will work until you have tried).
You can use any NI RT target with two ethernet ports as the Ethercat master. This could be a cRIO, PXI or RT Desktop.

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?

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,
Regards

LabVIEW Real-Time and Remote Front Panel MemoryManager.cpp line 437 error

Hi all,
I'm using a smartcamera (NI 1742) with LabVIEW Real-Time 8.6.
When I look at the Front Panel with the web browser and I close the browser or I Stop the executable, I always get this error: MemoryManager.cpp line 437. I've checked if someone else had this error, but I guess I'm the only person who got this error. I saw someone who had the MemoryManager.cpp line 406, but mine isn't on this line.
The application works well, but when I got the error, I need to reboot the smartcam to get it works. In my application, I use the Modbus library and I read/write binary file in the hard disk of the smartcam....
Anyone knows the solution?
Thank you very much
Stephanie

Hi again,
Still didn't find the problem on my side. Here's a picture of my code. If I put the code surrended in red at place (1), I don't get the error, but if I put the code at place (2), I get the error. Why oh why....?
I get the error when I close the browser or click Back button of the browser or Stop the application with the red dot or stop the application with the Quit button on my front panel.
This morning I found a post on this forum about getting an error using Property node and Remote panel (http://forums.ni.com/ni/board/message?board.id=170&message.id=252705). I did what they suggest: wire the property output to an indicator and it works (disable "Enable automatic error handling dialod" didn't work... I don't know why)... until I put extra code in my VI.
I really need help please!
Thank you
Stephanie

How to install the NI-DAQmx driver on a real time target PC?

Hi, I’m painful about how I can install a PCI-6363 DAQmx on my real time desktop PC target. The PCI-6363 is directly connected to the real time PC. And I’m using LabVIEW 2011 and MAX 5.0.
The DAQmx device driver can be seen in software lIst in the host PC, but it can not be found in the install wizard. Is there something wrong with my host PC? or is that wrong to connect PCI-6363 with real time desktop PC?
I would be grateful for any advice that I could get here.
Solved!
Go to Solution.

Hi Zhleo,
If you are about to use the PCI-6363 with the Real-Time Desktop you are right you need to have it installed, and then you need to deploy DAQmx driver software to the real-time target.
To do that you access your real-time desktop under Remote Systems in MAX and start the Real-Time Software Wizard. There you should see DAQmx listed.
In case you do not have DAQmx listed there, see this KB: Deploying DAQmx to a Real-Time Controller or PC?

Producer/consumer architecture over network variables with Real-Time target.

Hi all,
I am maintaining a producer/consumer data acquisition program to be deployed on a real-time target. The main code is deployed to and run on the real-time target during experiments, but was having trouble because the program was originally designed to write all experimental data to disk on the real time during acquisition, which puts the whole experiment at the mercy of the hard drive. I am now trying to rework the code so that the host takes care of logging, so that my time-critical loops don't have to wait.
I am currently using LabVIEW 8.5
I have two questions:
First, how can I programmatically call the data-logging subvi on the host so that it runs in parallel with the main vi which runs the experiment and collects data on the real-time? I have attached the test code that I have been working with to figure this out, but it does not run the logging vi continuously in the background. I am aware that there is better functionality for this in newer versions of LabVIEW, but I would prefer not to upgrade unless there is no other option. I would like to be able to run my data-generating vi and have it start the data logging remotely.
Second, is there a way in the host VI to read values off the network variable using an event structure rather than polling it for updates?
Any help would be sincerely appreciated!

Mark the target VI as served on the machine on which it will execute and use VI server Call by reference to invoke the served VI.

VI containing Event Structure will not receive front panel events in LabVIEW Real-Time.

Hi again, I'm working in my first UI (attached VI).
It works when running directly from PC. It doesn't when running from cRIO, there's the message "VI containing Event Structure will not receive front panel events in LabVIEW Real-Time". I've been reading and I found that "Event structures on RT targets do not support events associated with user interface objects, such as VI panels or controls. For example, associating the Value Change event with a control does not work. RT targets support only user events".
Is that the problem? If it is, how can I create Mouse Up, Mouse Enter, Value Change (or other user interface events) user events?
If I run my VI in FPGA mode should it run?
