Hi everyone, so we have a device for measurement & signal generation and want to make it accessible through VISA say by Ethernet / USB / Serial. Other than the VISA driver template and the SCPI parser that must be implemented on the device, does anyone offer a good starting point on how to make a device talk VISA and maybe even get it certified by NI? Thanks in advance

Hi Lava, I'm having an issue with a teststand deployment (Teststand 2013, LabVIEW 2013) I have a deployment which deploys my LabVIEW project containing all drivers (classes and lvlibs) for use in my sequences. In the deployment (LabVIEW options), I uncheck "exclude vi.lib", "exclude user.lib" and "exclude instr.lib" because the deployment should also work on an PC that only has runtimes and an operator interface. The build finishes without errors but I cannot open the deployed project... --> not on a development PC because it finds conflicts (XNodeSupport and some vi's in vi.lib picture.llb) --> not on a runtime PC (file not found) Did anyone else notice the same behaviour ? Thanks in advance for your help, tips and tricks :-) At first, i thought i had something to do with LabVIEW search paths (because I include vi.lib, it should not search for the vi's in the real vi.lib) but that didn't help... http://lavag.org/topic/18620-labview-search-paths/#entry111920

View File Threshold Hysteresis v1.0 LV8.6.1 The Threshold Hysteresis VI allows an input (for example, a sensor) to drift out of an inner limit without generating an invalid flag, but if it drifts outside an outer limit it then becomes invalid. For the reverse, when the input crosses back into the outer limit it remains invalid until the value falls inside the inner limit. For simplicity, only one input parameter is provided for both the inner & outer limits, and is negated for the lower limit, as generally tolerance limits are equidistant from the nominal.

Hi, I want to adjust the search paths in LabVIEW and i was wondering if I can add an entry to search the 'current project path' including subdirs. (a bit like teststand, current sequence path and subdirs) Reason: I have a few testsystems which run a teststand operator interface and a source distribution of my drivers (vi.lib, instr.lib and user.lib included) However... we have one system with teststand and labview development, for debug and test. If I build a project (teststand deployment) of my drivers, I get them in 1 folder structure. A projectfile with ALL subvi's needed vi.lib, instr.lib and user.lib included.... works on the testsytems BUT when I open this project in the dev env... the project has conflicts on Xnode support, picture to pixmap, Imagedata.ctl, .... I think that adding a search path in LabVIEW to search 'Current ProjectDir' including subdirs will solve my problem but I don't know the syntax for 'current project dir' don't even know if this is possible. Thanks for your reply. Wim

Hello, I need a little help. I want to send from LabVIEW to Arduino via serial port the string for example "ABC" and so on. The problem is that when I send the string from LabVIEW .......the Arduino do nothing. Sometimes shows some kind of sign. When I send the string via Visual Studio it works perfectly. Is there someone who can help me. I attached picture of vi and Arduino code Thank you very much. Arduino code.txt

I'm trying to find a way to communicate between two executable LabView app, because of several reasons I chose (associated with my application) Network Streams. Everything works fine so long as they are the VIs. When I build exe files there is no communication between apps. The apps waits forever for connection (because there is no timeout). Did anybody meet the same problem? I will be very grateful for any advices and comments. TestStream.vi TestStream2.vi

I need to protect an excel worksheet, and I use "USERINTERFACEONLY" As i also require some formatting such as merge cells and other option I use "ALLOWFORMATTINGCELLS" But I'm not able to run it... it say unlock and than run.... I do not want to unlock do modification and than lock method... Is there an alternative??? p.s. It works with kingsoft not with excel 2010...what?

I am currently working on a NI 9626 sbRIO with other external hardware using LV 2013. My issue is that my webservices will not load when I deploy the project as a startup application. I am able to manually click and publish the webservices, as well as manually right click and deploy the build. The webservices then run fine, and are publishing data from the application that is running. But for some reason, the board cannot seem to do both at the same time and on deployment as a startup. There are no errors, it acts like it deploys fine but then webservices never load and neither does the startup vi. Is there something I am missing that’s required in the build process to make webservices publish correctly on deployment as a startup? Thanks Edit: I have also posted this here http://forums.ni.com/t5/LabVIEW/Webservice-publishing-with-a-RT-startup-application/m-p/3019461/highlight/false#M862896 One thing I do notice however when I do try to run as startup is that when I try to login to the NI webservices config page I get this error:

I need to build a system where I have to control 4 or 5 small solenoid valves independent of each other using LabVIEW. I have two options: 12 V DC, 2W or 12/24 V DC, 6W. I am really new to LabView and interfacing. So this may sound dumb: 1.Do I need Arduino or some other kind of embedded system for controlling the valves? Or labview has some kind of module for that? 2.Will each of the valves need separate power source? Any suggestions are welcome. Thanks

Hi, I am new to this group, so if the post is not in some proper format, I apologize. I am trying to communicate Agilent 8563EC series Signal Measurement equipment. Using the example vi of controlling that instrument, I am trying to modify it to grab the center frequency from the instrument instead of popping the value from labview it self, i.e. I am trying to convert the center frequency from a control to a indicator. But, when I am trying to set the center frequency from the instrument, it is not showing up in labview programmed interface, instead it is changing the value in the instrument itself to 13 GHz, though I am giving it 55 MHz from the instrument. The value is showing properly when I am running the subvi of center frequency alone, but when I am trying to run the complete VI, it is inserting a garbage value in labview as well as changing my instrument parameter of center frequency. Please Help! Thanks.

Hello, In matlab the plot data can be save as a *.png,*.jpeg, and so on and even a pretty good option *.fig. Later when the *.fig is opened you have the real plot as before and this can be edited like changing the legeng , x and y labels, color of the plot etc,. Is there any option like this in labVIEW. I have seen options like saving the data into excel and to different image formats. Is there any special tool kit or add in functions??

I am working on an RT app and hardware that uses more than 50 USB devices connected via USB hubs to an NI rackmount computer. After a hard reboot of the rack mount computer, the USB devices and hubs take more than 5 minutes to enumerate. I am looking for a way to verify all the USB devices have enumerated. Polling VISA Find Resources appears to cause the entire system to lockup if we start it immediately in RT app. If we manually delay for 10 minutes or so in the application and then call VISA Find Resources, it appears to work OK as long as all of the devices have successfully enumerated. A hard-coded 10 minute delay is not optimal because on soft reboots, the delay is unnecessary. Are there any other ways to get the state of system USB enumeration other than VISA Find Resource? During reboots, the NI boot loader takes a minute or so to "Enumerate USB devices" but it appears it only enumerates each USB hub before it completes and moves on. PS. I know there are latency issues using USB on an RT system. We chose to use the RT platform for stability (no windows updates, etc) vs determinism. This may or may not be a good reason, but its what we have now.

Hi, I have some applications (executables) made by several VIs and when they start, users see "loading in progress" window which displays VI's names. This is a typical behavior of LabVIEW, that other languages don't have. Is there a setting to hide/disable that window? Thanks, Claudio

Attached is the browser program I am working on. I am trying to cycle through the database elements that are displayed in the cluster by means of a boolean button. Any help would be hugely appreciated Browser.vi

Well.... here it goes. This is my first LAVA post and I'm pumped! Figured I'd start out by asking for ya'lls (yes I'm from Texas) opinion on a side project I've had in the works for a while. I've developed in LabVIEW for just about a decade, even before my career at NI, and I've run into cases where I wished the array shared some of the characteristics of the cluster and the cluster had some attributes of the array. For example, I wish I was able to name and index my array elements by name like you can with the cluster while also not having to hard code that name on the block diagram with something like an unbundle. Almost like a dynamic unbundle by name... or something like that. So I've put together something I call the LabVIEW container that has the "dynamic-ness" of an array and the hierarchy mixed type named data "feel" of the cluster. It also behaves like a tree because of the "One parent - Many child" model. Here's a super short 5 minute video describing the concept and demonstrating a functional prototype. I've also created a community document that goes into much more detail and from which you can, if you so desire ( ), download the Container and give it a spin. I'm still doing a TON of cleaning under the hood, and adding things like VI documentation at the moment, but I'd like to get ya'lls feedback on the usefulness of the idea and thoughts on the API. This is something I'm really excited about and I hope that it benefits the LabVIEW community. Thanks ya'll!!!! Chris

Hi all, I am new to using LabVIEW and I was hoping to get some help with the issues I am having with my VI. I am working with a myDAQ that I have set to produce an analog output and also acquire data from a digital and analog input. I am then graphing that data on a mixed signals graph, which is working properly. However, the two waveforms on the graph are not synced. It seems that the digital input is off by approximately 0.05 seconds and I'm not quite sure how to fix this. I've tried using two separate DAQs but this didn't make a difference. I also thought that maybe I needed to use sample clocks for each of the inputs, however when I try using a sample clock with the digital input I get an error. Does anyone have any suggestions on how to approach this issue? I've attached a photo of my current VI. Anything would help, thanks!

I am looking to display images from an image folder containing mostly jpg images. I want to be able to display the images on the front panel and cycle through them through a button. How would I do this? This is what I have so far I just want to be able to cycle through the images by means of a button. LabVIEW 2013

Hi, I'm working on a build server to be launched from Jenkins and a plugin to smooth the use of Jenkins with LabVIEW. I hope to post some results soon! One problem I am having. I wanted to distribute the build server as source code as it will enable additional features in the development environment over a built EXE. To aid the process, rather than distributing multiple versions and have to create a new distribution for every version. The problem with this is that when it tries to exit, unless it is in the version it was created in (2011) it prompts for a save. I'm sure I saw some option somewhere to sliently close LabVIEW without a save dialog but cannot find it anywhere! Was I dreaming or is there something in Scripting/Super Secret Stuff which could do this? Cheers, Mac

I want to use the Python extension libs such as ROOT (http://root.cern.ch/drupal/content/how-use-use-python-pyroot-interpreter and http://root.cern.ch/drupal/content/production-version-528), but it is strange for me to use the labpython. I write a demo.py to import ROOT(just like this "from ROOT import gROOT, TCanvas, TF1") which is running in LabPython, but it seems to crash for LabVIEW, but it can be used outside of LabVIEW if python it in the command line. And If I run the python script without ROOT lib, it is normal in LabPython. How can I solve it? My python version is 2.6, the ROOT version 5.28, and LabVIEW version is 2011. LabPython version is 4.004. The Python file could not be uploaded, so I change the name from demo.py to demo_python.vi. Please change it after download. And LabVIEW file is also uploaded. My ROOT env config variables are set PATH=%ROOTSYS%/bin;%PATH%set PYTHONPATH=%ROOTSYS%/bin;%PYTHONPATH% So after setting config variables, you can type the command "python -i demo.py" in the python installation directory in the command line. It is normal running, but you could not do it in LabPython using the same code. And My LabVIEW.ini is setting like this: PythonServer=C:WINDOWSsystem32python26.dll Thanks! demo.vi demo_python.vi
