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?

The Problem about Monitoring Motion using PCI-7358 on LabVIEW Real Time Module

Hello everyone,
I have a problem about monitoring the position of an axis. First let me give some details about the motion controller system I’m using.
I’m using PCI-7358 as controller and MID-7654 as servo driver, and I’m controlling a Maxon DC Brushed motor. I want to check the dynamic performance of the actuator system in a real time environment so I created a LabVIEW function and implemented it on LabVIEW Real Time module.
My function loads a target position (Load Target Position.vi) and starts the motion. (Start.vi) then in a timed loop I read the instantaneous position using Read Position.vi. When I graphed the data taken from the Read Position.vi, I saw that same values are taken for 5 sequential loops. I checked the total time required by Read Position.vi to complete its task and it’s 0.1ms. I arranged the loop that acquires the data as to complete its one run in 1ms. But the data shows that 5 sequential loops read the same data?

Read Position.flx can execute much faster than 5 ms but as it reads a register that is updated every 5 ms on the board, it reads the same value multiple times.
To get around this problem there are two methods:
Buffered High-Speed-Capturing (HSC)
With buffered HSC the board stores a position value in it's onboard buffer each time a trigger occurrs on the axis' trigger input. HSC allows a trigger rate of about 2 kHz. That means, you can store a position value every 500 µs. Please refer to the HSC examples. You may have to look into the buffered breakpoint examples to learn how to use a buffer, as there doesn't seem to be a buffered HSC example available. Please note that you need an external trigger-signal (e. g. from a counter of a DAQ board). Please note that the amount of position data that you can acquire in a single shot is limited to about 16.000 values.
Buffered position measurement with additional plugin-board
If you don't have a device that allows you to generate a repetitive trigger signal as required in method 1.), you will have to use an additional board, e. g. a PCI-6601. This board provides four counter/timers. You could either use this board to generate the trigger signal or you could use it to do the position capturing itself. A PCI-6601 (or an M-Series board) provides can run a buffered position acquisition with a rate of several hundred kHz and with virtually no limitation to the amount of data to be stored. You could even route the encoder signals from your 7350 to the PCI-6601 by using an internal RTSI cable (no external wiring required).
I hope this helps,

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.

Can you use event case with labview real time?

I have a real time application I am putting together and until recentally have concentrated on getting the data acquisition working as expected.
I am using a PXI-8183 in a 1031 chassis.
I am now trying to add the functionality for setting up the system in the form of a GUI remote front panel that I connect to with a host laptop. I am connecting with the host as expected and it seems to be working well in that respect.
My problem is with event cases, operating in a while loop on the target. They just dont seem to want to trigger when i click on a button I have set an event for.
I have looked through the documentation and cant see any reference to issues with event cases on rt, but I feel I am missing something fundamental. Can anyone help?
Regards,
Barry

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.

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".

Using PCI-6251 with Labview 6.1

I recently purchased a PCI-6251 multifucntion DAQ board to get a higher sampling rate than my old PCI-MIO-16E-4 board. However I have existing software that I want to run on the new board. The board came with NI-DAQmx which will only work with Labview 7 or above. I am currently running NI-DAQ 6.9.3 and the Measurement and Automation program does not recognize the new PCI-6251 board. Is there anyway to get Labview 6.1/NI-DAQ 6.9.3 to recognize and configure the new board? Or will I be forced to upgrade my Labview?

The M-series boards (PCI-62xx are M-series) require NI-DAQmx driver. The NI-DAQmx driver requires a newer Labview. No way around it.

When I use Adobe Bridge with PSE 8 is asks for my serial

I just launched Photoshop Elements 8 for Mac and chose to use Adobe Bridge to find images. Adobe Bridge opened and I found the image I wanted but when I double-clicked on the image a Photoshop Set-up dialogue box appears asking for my serial. So, I found my serial in my email because I bought the digital download and it says my serial is wrong. The weird thing is is that PSE is running and works fine. So why is Adobe Bridge asking me for my serial and rejecting it?
thanks
Jerry

Subversion is a program/system that stores files on a server, does versioning, etc. We use it principally for code management but also for our image files. It integrates into Windows explorer so you can check-in/check-out files, etc.
I was just wondering if there was a way to use Adobe Bridge as the front-end for it somehow.

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.

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications?

What are the limitations of using labview 8.5.1 developers suite verses a real-time module in field point applications? Can an exe. be loaded onto a field point controller or does the controlling program have to reside on a PC for example?

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.

Error 1003 when loading a VI dynamically on LabView Run-time ini file configuration

hi all,
I have a problem with my runtime excutable.
On 4 systems, all running XP it runs fine.
On 2 systems ( one a new install of just LVRT 2011 SP1 ) I have:
Error 1003 when loading a VI dynamically on LabView Real-time
Or more spoecifically the error code is 1003 and the error source is Open VI Reference.
When the RT app runs correctly I get these paths:
Path Sent to Open Vi Reference: Yeast_Grower.exe\Tecan_talk_Control.vi,
Path Returned from Open Vi Refence: C:\Program Files\Yeast_Grower\Yeast_Grower.exe\Tecan_talk_Control.vi,
On a system that does gets the 1003 Open Vi Refence error I have the same Path Sent but of course no path returned as it does not open.
To be sure that the vi Dyanmically called vi is compiled and valid at runtime I also include a copy of in the main.vi.
To be extra sure I have also installed the runtime versions of VISA and DAQmx.
I have compiled it with and without the "Use LV 8 calling hiaracy"
My conclusion as this stage is that either the installation of LVRT 2011SP1 misses something the earlier LVRT installtions make.
or is there a MyApp.ini or LVRT .ini that controls how the RT dyanim calls are handled.
Help very welcome how to solve this puzzle.
thanks
michael

I understand that all the PCs (6 of them) have LV 2011 SP1, runtime or the development system installed. Right?
How many of these PCs have the source code available on them?
-> Only one of them has the source code.
I am not sure I understood 'I also include a copy of in the main.vi'. Does it mean you placed the subvi in the main.vi?
-> I meant I have included in main.vi the actual vi that is called dynamically - but only where it is not called.
Did you try including the sub vi which is called dynamically, as 'Always included' in the EXE build?
-> No, I did not know of this option - but the above I did this by default.
Edit: Did you verify the software versions of LV RT, VISA etc on all the PCs? Are they same?
-> I did verify even added DAQmx just in case
There is lots of material available on this forum for error 1003 and dynamic vi calling. Did you find anything useful to try among the forums threads?
-> I did view many of them.
I did finally find the answer.
I have a subvi (callNet.vi ) in the dynamically called vi (dynamic ) that calls .Net libraries.
Now the thing is that this subvi callNet.vi is coded out by enclosing it in a Disable structure.
In fact this subvi ( callNet.vi) does not even compile - ie it has a broken arrow
however if enclosed in a Disabled structure and disabled, the enclosing vi compiles OK.
However I have discovered that even with the .Net calling subvi (callNet.vi) in the Disabled state of the Disabled structure
the enclosing vi (dynamic.vi ) does NOT run - although it compiles just fine.
Once I installed the .Net libraries (I actually did include them with my app installer ) with the vender's supplied installer
then my app now successfully calls the dynamic vi.
So the Summary and warning is: Even if the dynamic called vi is included in Main.vi and Main.exe runs ( but does not call the dynamic vi - except when called dynamically at later some point ) and even if, in this case, the .Net calling subvi is disabled out ie no .Net calls are made the dynamically called vi will not run when called dynamically.
I hope that is not too confusing. In summary it seems the Disable structure does not entirely disable.

Real Time Module needed for hi speed digitizer PCI 5911 ?

Rookie question :
I run LV 7.1 , LV Run Time 8 ( whatever this Run Time Engine may be ) , MAX 4.0.0 , NiDaq 8 ( for my two Multi Function PCI Daq's ).
Question : does the PCI 5911 work under NI-Scope 3.3 ( supporting PCI 5911 ) without a Real Time Module ?
i.e. is the Real Time Module a separate ( hardware ? ) device, not necessarily needed for PCI 5911 ?
Sorry for this utter basic question.
I have not used a hi speed digitizer before, only multifunction NiDaq's.
Thanks for any help or reference.

You are probably referring to the LabVIEW Real-Time Module described here.
This is an extension to LabVIEW that allows you to run VIs on a
real-time, deterministic environment, usually on remote hardware. One
common configuration is to use a Windows system as your host, and
communicate to a remote PXI controller running LabVIEW RT.
The PCI-5911 is fully supported for "standard" LabVIEW running on Windows. You don't need LabVIEW RT to use it.
In fact, the PCI-5911 is not supported under LabVIEW RT.

Screen light auto turn dark when I use program/web with background dark in windows 8.1

Hi there,
I used HP Pavilion dv6t-6000 CTO Quad for 3 years.
CPU: Intel core i7-2630QM
GPU: AMD Radeon 6490m
It build in windows 7 and I manual install ( fresh install ) windows 8. It's fine. But when I upgrade to windows 8.1, it have an issue and I really hate it.
When I use "Sublime Text" ( with background is black ), the screen light is become darker. And when I back to ( e.g: a website with background is white ), the screen turn back to lighter.
I tried many ways, included 4 ways here but it's NOT WORK.
NOTE: When I used Option 1 ( upper )
1. Open PC settings, and click/tap on PC and devices on the left side
2. Click/tap on Power and sleep on the left side, and turn on or off Adjust my screen brightness automatically on the right side under Brightness.
==> It's NOT SHOW button "Adjust my screen brightness automatically". It mean: I have NO built in auto brightness sensor.
I think this issue is about AMD driver or Intel Graphic driver.
Is anybody have idea???

Can I use a DAQ PCI-1200 with Labview 5.0.1?

I have a Labview 5.0.1 software, and I want to use PCI-1200 with it. Can I do that? My OS is Windows XP, but I can change it with Windows98/2000.

Hello jhylee,
The latest NI-DAQ driver for the PCI-1200 is 6.9.3, which is compatible with LabVIEW 5.0.1. LabVIEW 5.0.1 supports Windows 2000, but not Windows XP (although it may still run).
