• Pilot NI VISA - problems of driver installation wizard

  Hello

  I generated a pilot with communication as to the NI VISA driver with a USB - HID Device Wizard. Driver and LabVIEW Application work fine - on the development system (Windows 7 x 64).

  Now, I want to move the application compiled to another PC, using the same operating system (Windows 7 x 64). I tried to install the generated driver by clicking on the inf file and choose install. After that, I will ask if I want to install the driver, which I agree. The installation process runs, but in the end, the device is not visible in the Device Manager.

  So I went in the development system and uninstalling the driver real. Now, I did the same steps as above (right-click inf-> install->...). Same problem, the device is not visible in the Device Manager.

  Now, I went back to the pilot NI VISA Wizard. With it, I am able to install the driver.

  How could install an inf generated on a system without a VISA NEITHER pilot Assistant?

  Thank you very much.

  Best regards

  Michael

  Hi Michael,

  OK, I thought he should there have generated one or more other files which can be transferred to another machine and that should be installed with the inf file.

  I did some research and discovered things about the problem. Please go through the links below and see is they solve your problem:

• VISA problem on a PC but not another

  Hello

  I've been successfully running a vi on a 32-bit XP computer to connect to an instrument via RS232. I have put the same vi on an old computer XP 32-bit, but getting a VISA error.

  I can control the instrument of the same old computer using the same port, but running an application tailored to the instrument, then the hardware and port works fine.

  I used a serial port monitor to watch what is happening. When I run the vi nothing appears in the port.

  Can someone give me some clue to begin looking?

  Thank you very much

• driver usb visa problem

  I have a usb controller, I want to connect with labview... I did successfully usb raw driver using driver development Assistant... and it works well in my pc in which NEITHER labview is installed... now I want to run a labview application in a pc in which no labview (nothing not related to NOR) is installed... then I copied the visa to this pc... usb driver after plugging the device and install the driver it says unable to install driver completely... I tried with 2 PC... so I wondered outside the visa usb driver... y at - it something to install on a pc that does not have labview so it can communicate with the pc?

  I don't know the length of LabVIEW. I want to talk about the VISA duration.

• Writing of VISA problems

  Hi all

  I am trying to write 2 bytes for VISA on click of a button.

  My device receives the bytes 2 sends data.

  I use "byte array to string" to write these 2 bytes to VISA.

  It is when I click on the button very slow (say, on a distance of 1 sec) it works fine. but I click on the button very quickly, it crashes and stops finally LV

  Is there a way to better and faster to write data on the instrument?

  Thank you

• VISA problem read: after a while the device stops responding

  Hello world

  I am faced with a really strange bug than anything I've done him could not solve. I have a camera that I made myself communicating with LabVIEW by a RS232-> USB converter. Everything seems to be ok, but all of a sudden (it can last 30, 45 or 50 seconds), judgments of LabVIEW and data reception, as well as other buttons are no more, not even the stop button. I have to remove the usb converter to get the buttons answer once again, and then I got the error:

  

  Other programs that opens this same terminal can communicate with my camera for hours without errors. I have of course the session open and close only after the while loop. Can someone help me?

  How fast your VI reads the com port?... could he try to read too fast?... Add a waiting in your VI and see if that helps.

  Just a thought...

• VISA 1073807343 errors and 1073807202

  Hello everyone,

  I have several issues with the VISA 5.0.3 and LabVIEW 2010 SP1, and I don't know if or how they are related, so I'll post as much information as I have here. Please excuse the super post long, just trying to be thorough.

  Error BFFF009E (same as 1073807202 I think) appears to the MAX aperture as seen in attached ss1. When you try to open the VISA Interactive Control (IC), I get the message "failed to initialize the library VISA. The VISA interactive control utility will leave. "When I open any VI with a VISA resource and try to click the drop down arrow on the right to see the resources available, the arrow remains derpessed during a second, no field drop-down list is displayed, and then it returns to its original blank State. These problems all live together now, but before I could select BT VISA resources and use VISA IC, while I have always seen the error MAX.

  I tried to fix VISA, as well as VISA uninstall-reinstall 5.0.3 which I believe is the most recent version. No change. I also checked that visa32.dll exists as suggested in the article below. See systeminfo.txt attached to the installed software.

  This error seems to be related to an oscilloscope Tektronix DPO 2014 I connected via USB (or maybe something to do with TekVISA?). By this I mean that if the scope was connected when my computer started, this error occurs. When the field is not connected at startup, I don't see the same problems as above. Instead, I get...

  Error 1073807343 (BFFF0011) when you run a VI with a VISA resource to a serial device (see ss2), or connecting to the device in IC of VISA (see ss3). I also always see the error of BFFF009E to the MAX, but not the other problems on front. I can connect to these serial devices in hyperterminal and communicate very well here. Seems similar to the post below and also, I can't find visaconf.ini, but the solution does not apply as I LV 2010. In addition, ironically, I use VISA very well talk to the scope (whether to the MAX or LV) via USB if I connect after booting.

  http://forums.NI.com/T5/instrument-control-GPIB-serial/using-HP34401A-in-LabVIEW-yields-error-code-1...

  I use series of USB adapters made by Ultra (http://mail.ultraproducts.com/product_resources.php?cPath=35&pPath=782&productID=782 ) to go from instruments of series to my USB ports and the computer I'm unfortunately has no serial ports to be tested with, nor do I have another brand of the adapter. I know these converters can sometimes be a VISA problem, but I was certainly with it even without problem before.

  They that all seem to have intermittent problems, because I have seen both before as I have developed and pushed to go to strange as things exchanging (apparently identical) USB extension cables or restart a dozen times. This issue has been driving me crazy for weeks, I am looking for help to try to solve it finally.

  Thank you

  I think I got especially. Looks like it was TekVISA who got in the way, and if Visa32.dll was in the right place, it appeared (in properties > details) as the version of Tektronix, not the version of LabVIEW. After you have uninstalled all Tektronix as well as NI-VISA, he had disappeared, but no money to install or repair NI-VISA would be replaced by a version of LabVIEW Visa32.dll.

  However, with the help of the article from the link below, I discovered that the repair of the installation of the driver NI-VISA DURATION is what replaces Visa32.dll, as opposed to NO-VISA just as messages of error and other links seemed to suggest.

  http://digital.NI.com/public.nsf/allkb/B283196340462DFD86257633006DC799

  Now all the VISA stuff works again, except of course for the scope of Tektronix. I'll keep this battle for the future. Guess I just needed to talk to myself for a while.

• Cannot find the drivers of visa

  Hi all with that I have some visa problems drivers, I have the following error

  LabVIEW: visa (hex 0xBFFF0009E) or a library of code required by visa could not be located or loaded. This is usually due to a required driver is not installed on the system.

  I know that there is a problem with the driver but when I check my windows drivers in the laptop Device Manager it say that the device works very well.

  also I did not receive this message once before and today when I tried to run the sample, this error pops up, I did not change the parameters

  also I m using labview 2009 and my laptop is dell d830 with vista running on it

  regarding

  The windows driver and Device Manager have nothing to do with VISA. Have you tried to reinstall or repair?

• Reconfigure the channel RS232 VISA

  If I need to reconfigure a VISA (RS232) channel (flow rate in baud, timeout, stop bit, etc) I do first had to close the channel and reopen/configure it?

  I'm currently in the way of the already existing VISA reference in configure it VI and defining a new rate in baud rate and timeout.  Currently, it seems to work very well, but I wanted to make sure that I'm not setting myself to hard to track bugs later.  If anyone has experience with the reconfiguration of this way and ran into problems or knows that it is a free way of reconfiguring a channel RS232 VISA problem I'd appreciate the feedback.

  See attached screenshot for a Visual

  Thank you!

  No problem!

  Really! you apply just new property values to an existing resource of VISA.  One of the advantages of not having to use open VISA

• VISA with Keithley 236 questions

  I use the Keithley 236 in LabVIEW 8.5 and am having some VISA problems.  I can't find a write buffer command that works with the 236.  No one knows everything?  If you need more ask for details, but I can't provide you with the vi because his ITAR restricted.

  What is 'it' that returns IDDC? This isn't a VISA error code.

  What I suggest is that you forget to LabVIEW for now and concentrate on debugging of a GPIB communication base. In MAX, peripheral slot, and Interfaces your GPIB card must be listed and under who should be listed the instrument if you have followed the installation instructions. If the instrument is not listed, click with the right button on the controller and select 'Search tools'. When and if the isntrument is listed, you can right click and select "Communicate with instrument. You have the option to do a writing, reading or a query. This is where you should start to debug commands.

• LaCie FW 800 PCMCIA card low speed in Vista

  I have a pcmcia card from Lacie FW 800 - whith on my old Toshiba Qosmio gives me speeds of more than 50 MB per second read. Now with my nice new Satellite and Vista it barely reads @ 7Mbs and written to a pathetic 2Mbs. Any idea of before I get rid of Vista as a waste of time.

  Dermot

  Hello

  Well, it's not easy to tell if it s a card PCMCIA slot issue or Vista problem.
  But I noticed that some users have had a slow performance PCMCIA with Vista on laptop series different. So I have to say that it s a Visa problem.

  But it would also be interesting to know the performance with XP, then compare the two results.

• Subvis call go dynamically within an exe file (avoiding the error 1003)

  Hello

  I use an architecture where the main program (compiled into an exe) can be supplied with a user-'plugins', which are collections of screw types inside a folder named especially compared to the exe. They can be called in the exe via 'open reference vi' provided by the corresponding strict vi types and corresponding relative paths.

  I want to avoid having to include one of the plugins in some way in the application builder, because users must be able to create own plugins that the request is totally ignore during the generation.

  In principle, this approach works rather well, since these plugins are not extremely complex, but sometimes, I get an error 1003 when loading a plugin.

  I have read many old posts on this error in this particular situation, mainly using versions of LV 7 or 8 (I use 2012). It was suggested to build a source distribution for each plugin, including everything that is used from vi.lib, instr.lib and user.lib. Indeed, it helped in my particular case - however, it bloats the plugin 'distribution' (which consists originally only a couple of the screws of the user) extremely and complicates the development user side.

  Now some good plugins run from in the exe without having to build a distribution source for them (they still use many vi.lib live) while others don't, and I have no idea why...

  These plugins are wrappers for hardware drivers that allow to control any hardware instrument within the main application via a certain API. So, in a particular case, a plugin that produces the error 1003 uses VISA series features (everything inside... \vi.lib\Instr\_visa.llb) and one without error doesn't (yet he uses several features of... \vi.lib\Utility\...).

  I can solve VISA problems in a simple way by including (only) the VISA-vis opportunity (and typedefs) inside the plugin folder and explicitly link to them (i.e. replace the VISA-vis of vi.lib with those copied to the folder of the plugin - I guess that's also what the source distribution).

  However, I'm confused why certain plugins with work of related vi.lib while others screws produce an error 1003 unless these special screws are explicitly distributed and connected with them...

  Oh and just for completeness: all plugins are working fine if the callee in the development system, the problem occurs only if called from an exe file.

  Do plug-ins that work depend on the screw in vi.lib who are already part of your executable file because the main program uses these same screws?

  All the screws that your plugin needs must be available, if applicable can mean to be already loaded into memory (for the main of the application or another plugin), or can be found on the disk and load.  An executable includes all the screws of vi.lib - it includes only those he uses (and the screws that are marked always 'include' in the build specification).  I suspect that the plugins that work only dependent vi.lib screws which are also used by the main executable file.

• -63043

  Anyone know what is the error-63043 is on about?

  I have a sensor data grabbing cRIO-9074. all ~ 2 seconds.

  The main PC program uses Open cRIO VI reference first and then starts a loop in which a read/write control reads data every 10 seconds.

  If a read/write control error occurres, the close FPGA VI reference is then called the open FPGA VI reference gets things going again.

  I see three errors,-63043,-63195 and-63198, not all at once, not all the time, maybe twice a day.

  Can anyone offer any idea?

  Thanks Mark,

  The note of application-63195 error indicates a VISA problem. A cRIO communicate as a VISA session?
