• NEITHER 9512 with Labview FPGA Interface

  Is it possible to use the NI 9512 stepper with Labview FPGA interface drive unit or is it only possible to use it with the interface of scanning? When I try to add the module to a FPGA target, I get an error telling me that Labview FPGA does not support this module with the latest version of NOR-RIO, but I have the latest version of OR-installed RIO.

  Hi Checkit,

  You're right - the 9512 cannot currently be used in FPGA. There is an error in the documentation. The 9514 and 9516 can, however.

• Any camera regardless of the interface is available for use with the LabView interface.

  Hello

  I intend to go for some CMOS camera,

  but I have a huge doubt before buying, the camera of menttioned above is not anywhere in this list. Nor can I see any type being supported USB device.

  The question is

  1. is a camera regardless of the interface is available for use with the LabView interface?
  2. Can I build a VI to communicate with any device image and recording of camera and take the data?

  Any kind of help or advice is greatly appreciated... I have to buy a CMOS camera and begin to run.

  Thank you...

  Hello Virginia,.

  I am pleased that this information has been useful, one thing I wanted to mention is that USB 3.0 has its own standard USB 3.0 Vision which is currently not supported. If this camera is also Direct Show compatible then you will be able to acquire an image using IMAQdx and manipulate all the attributes that are published to the API Live Show.

  I hope that USB 3.0 Vision will be supported in the near future, and we tentatively announced for this standard of communication for the August 2013 Vision Acquisition Softwareupdate.

  See you soon,.

• using NI USB 9201 with LabVIEW Real-time

  Hello

  I try to use a USB of NI 9201 on a remote real-time target. Here's what I did: 1) tricked out of a desktop PC to serve as target RT using the instructions provided on the Web site of NOR. He now starts in an RTOS with LabView RTOS 9.0. (2) I communicated successfully with the help of a host computer that has a windows with LabView 2009 BONE and I installed the software from the computer remote RT target host using ethernet. However, my problem is when I plug NI 9201 USB on the target RT that I do not see the material listed on the devices tab in MAX and interfaces on remote systems. I tried to get the manuals for the HW 9201, but it seems not much explained here, or maybe I'm looking in the wrong places. Any help is greatly appreciated.

  PS: I am attaching 2 JPEGs for additional explanations (tab network settings and the settings of the system).

  Thanks in advance,

  Benoit.

  AVS,

  9201 USB is not supported on RTPCs please visit this link. Currently no usb-DAQ devices do not support an environment CRPC. Only the PCI DAQ devices are supported.

• Possible GPIB communication through interactive control of Visa, not with Labview

  Hello

  I have a communication problem with Labview with GPIB instruments (with functions of visa).

  I get:

  "Error 1073807298 occurred at the VISA opening

  Possible reasons:

  "VISA: (Hex 0xBFFF003E) failed to perform operation due to i/o error."

  However, it works with an interactive control visa and this is where I am confused!

  Here is my setup:

  -Labview 2011 assessment

  -VISA 5.1.2

  KUSB - 488B with the associated drivers (adapter USB to GPIB of Keithley)

  Because I can speak with my instruments in visaic, I guess the installation of drivers for the Keithley interface is ok.

  Trace IO NOR I see beeing of commands passed through Labview to VISA so that they "see" between them.

  I found a thread where someone had the same problem and its solution was downgrade to Labview 8.5.1, which is not possible for me.

  http://forums.NI.com/T5/instrument-control-GPIB-serial/Keithley-2700-driver-problems/TD-p/1474212/PA...

  You have an idea to solve this problem?

  Kind regards

  Baptist

  Here's a follow-up on this issue.

  I tried with Labview 32-bit on main machine: it works.

  The pleasure is that I have to use Labview 64-bit.

  So the ultimate solution is now to run a client and a server of visa on the machine: Labview 32 bit can directly access my resources GPIB, Labview 64-bit must go through the closure of the network.

• Is there any interface virtual native network for Mac OS

  Hello

  I'm trying to do something with the interface of virtual network on Mac, I need to operate directly on the device (similar to tun/tap) virtual network. As we know, tun hails from Linux, so it's good to use it under Linux. And I wonder if there are all these virtual network "native" Mac interfaces?

  Thanks in advance.

  There is a built-in driver called 'Amadou' which is functionally equivalent to "tun". It has been used to implement OpenVPN clients. You will need to look for more information. Nothing can "tap."

• ACS550 control with LabVIEW

  Hello

  I recently implemented an ABB ACS550 player to control an air blower speed.  I was control the player through the interface on the disc itself.  However, I am now looking to control the device with LabVIEW.  I don't know where to start and I was wondering if someone could explain what I would need the equipment and the basic principles on how this control can be implemented.

  Thank you!

• Google maps route with Labview

  I have a project where I need to generate driving directions between two points on Google maps and use the database Google KLM / or any other database to determine how many miles were driven in each State where the road.

  Does anyone have an idea how to accomplish this task.

  Hello Christopher,

  I could find a few documents that should help you get started.

  First of all, I found a tutorial for using the JavaScript API of Google Charts with LabVIEW.  It uploads the data to a web service using SQLite and JSON.  You can modify this example to load the data on a web server running the Google Maps API, and then download the distance.

  http://www.Bloomy.com/sites/Bloomy.com/files/bloomy_whitepaper_upandrunningwithlabviewwebservices.PD...

  Secondly, I found a document using MySQL and PHP to interface with Google Maps.

  https://developers.Google.com/KML/articles/phpmysqlkml#outputkml

  You can use the LabVIEW database tool to access MySQL databases. For this toolbox user's Guide will get you started with these screws

• Can what cards I use to develop communication SPI with Labview?

  First of all, I'm an intern is currently working on a project that involves communication with an SPI interface. I have absolutely no experience with SPI, but I finally decided to try. I work for about 6 months with labview and understand the function of basis of a large number of its resources.

  The problem:

  We want to connect Labview to an evaluation Committee that is connected to the PC via USB (but it can also be adapted to connect through SPI). The evaluation board mainly reads and writes if sign up for issuers that are connected to it by a Module assessment. The program which is already which is the Studio of SmartRF (that works via USB), but as we want to link all the functions in Labview we redevelop a platform to do so. If shortly, we want to make a Studio of SmartRF version in Labview. We want to be able to get all the information that makes the program and others... and all this is possible through SPI.

  Here is a link in case you are interested what is SmartRF Studio: SmartRF Studio link

  My question is which card do you recommend for what we are trying to accomplish? We are looking for something not very expensive but who fail to meet our requirements.

  I think of the NI USB 8451, but please make suggestions.

  Thanks a lot in advance and please stay tuned to my many questions coming about how to accomplish this enormous task with no knowledge whatsoever of SPI or how to mix with Labview only one student. I am reading as much as I can find, so all the links will also be very much appreciated. If anyone has any experience with NI USB 8451 with Labview be kind enough to guide me

  Sincerely,

  Gisela

  If you have very little experience with LabVIEW and SPI, the 8451 is a good choice. It's expensive, but it's really easy to use and configure.

  The Aardvark is also a good choice. There pilots LabVIEW is also easy to use in LabVIEW. The disadvantages is that it doesn't have a lot outside of simply making SPI or I2C - in other words, it doesn't have a lot of GPIO. This can be important when control of multiple SPI devices, because it requires to select them lines individual slave.

  Dinah is really more than a product of laboratory, or something that is meant to be placed inside a camera. It is expensive, compared to the other two, but it doesn't have native drivers in LabVIEW. On the contrary, it comes with a DLL you can call from LabVIEW. I wrote a set of LabVIEW drivers for it, but I can't distribute.

  There are other products on the market, which some will resemble a device series to your computer. For example, you would use VISA to communicate with the SPI controller, and it would appropriate communication of SPI.

  Among the three mentioned here, I would suggest that you go with the neither of the Aardvark, one.

• I need assistance with LabVIEW RT and dll

  Hello!

  I'm new to LabVIEW but I am facing something very difficult.

  I develop with LabVIEW 2012 on a cRIO-9082, and I would use a specific DLL in a VI. The DLL is called TcAdsDll.dll and it is used to communicate with a PLC. (This DLL is provided by Beckhoff, for more information: http://infosys.beckhoff.com/index_en.htm TwinCAT > TwinCAT system > TwinCAT connectivity > TwinCAT ADS).

  When I use the 'library of the call' function with the DLL, I get an error 7. I'm just trying to call a simple function of the DLL.

  I know that in LabVIEW RT (Pharlab) only certain DLLs are supported. I also checked the DLL with the tool of NEITHER, but after the 10th dependend DLL calling it just hangs.

  If someone is able to provide assistance, I would be very grateful!

  Does anyone know, what are the rules for the dll must be met to use in LabVIEW RT?

  Thanks in advance!

  A DLL must call only Win32 API supported by the Pharlap ETS system in question in the first place. Since NO guard updated the ETS with almost every new version of LabVIEW it depends actually. DLL checking tool is the only way I know to check this. If this DLL checking failures, or as in your case tool breaks down, the DLL is not justifiable on the RT system. The Beckhoff ADS DLL is a complex beast with many dependencies on any other DLLs Beckhoff and what else, and as such a bad candidate to run on NI RT systems.

  In addition to this fundamental questions, you have additional problems with the Microsoft c runtime library in his infinite wisdom, has decided to create a new C runtime library version with each new version of Visual C. It is already a problem for a developer when deploying to standard PC Windows, but gets a problem almost unmanagabel when targeting something as Pharlap ETS. NEITHER seems to have paid the MS C runtime for their version of the toolchain Visual C of choice for LabVIEW RT system, but this isn't an option for you. If the 3rd party DLL to be used has been compiled in a version of Visual different C that ANYTHING used for the RT version you want to use, then you almost certainly run into trouble, unless the DLL was created with Visual C 6.0 (now a very old version)!

  I've created in the past as a VI based entirely the LabVIEW ADS communication library. It is a tedious job to know the actual byte stream protocol. Unfortunately it is not something that I can share with the community.

  Your best bet would probably be to use the cRIO Ethercat solution and go with an Ethercat on your PLC interface. EtherCAT is sort of a superset of the ADS interface.

  Maybe you can also talk with these guys here. They have a few ADS LabVIEW library and Ethercat libraries too. Not sure if they are basic DLLS and if they would be compatible with LabVIEW RT well.

• pxi7852r with labview 2011

  Hello

  I have a pxi-7852r and I just installed labview 2011, but labview 2011 says that the device is not installed.  If I go to labview 8.6, he sees the card without problems.  Any help would be appreciated.

  Thanks in advance

  Hi efriday4455,

  You have the NOR-RIO driver installed? You will need version 4.0 to the R with LabVIEW 2011 series map interface, and it must be installed after LabVIEW has been upgraded.

• Is it possible to use a Linksys by Cisco Wireless - G Internet home monitoring camera with Labview

  I was wondering if it is possible to use a "Linksys by Cisco Wireless - G Internet home monitoring Camera" with Labview

  http://www.dabs.com/ProductView.aspx?quicklinx=53PX&SearchType=1&searchTerms=network+cameras&PageMod...

  I wan't to be able to get the raw data from the camera and analyze it.

  I found a simple soloution to this problem,

  Is possible to use a web browsers invoke node basically give a screenshot of the web page (get image)

  It can then be loaded into a display of the image and will show exactly what the web browser is showing and can also be analised by unflattening the pixmap.

  Maybe it's not the most effective method, but he turns my rig fast enough and does the job

  It may also be a setting value of the display of the photo to "smooth updates" that gets rid flashes white as the changes to the image, if anyone else has this problem.

• simulate induction motor starting with labview online

  Hi all

  I want to simulate induction motor in line beginning with Labview. I installed labview control design and simulation, simulation interface toolkit 2009

  No, because I don't really know what you're doing.

  What you're faking?  So far, what you wanted to do is how to "simulate" turn on an engine.  A motor is either on or off.  If you have a Boolean value which would lead to a digital output which would drive away a contactor/starter motor if you had one of this material.  Since you do not, all you can do is put a Boolean indicator on your façade.

  You want to simulate these sensors entries as well?  Then put a few orders of front that you can adjust you can replace later with the signals from these sensors.
