Hi, I have a big project to manage which includes :-TestStand + LabVIEW-SQL Database for test inputs (UUT characteristics, sequences parameters,...) -HTML Reports -almost 10000 different part numbers (that's THE point) with common characteristics (almost 3000 families) + specific characteristics Everything has to be imaginated. The SQL inputs tables have to be created. The number of sequences to code has to be reduced to the minimum because, of course, it's impossible to code 8000 sequences differents files... The final solution must be as simple as possible. Possible ways of reflexion : -XML and Xpath for families and their children -Intermediate LabVIEW OOP layer for families and their children -Dynamically created sequences + variables (TS scripting)-Dynamically created sequences (concatenating a bunch of generic sequences to build a specific sequence) There is a lot of documentation about TestStand and SQL, but only for results (outputs), not really about inputs. Does anybody manage this kind of project ? In which way ? What would be your advices ? Thanks, Sébastien CLA

I was Googling around on the subject of graphical programming and open source and came across this. I have never seen it before. It looks pretty rough and new, but also very familiar. Seems to be Java-based. I have not yet downloaded it. Has anyone else seen this? Opinions please. http://www.zaluum.com/index.html

Hi, guys, From the attached image, you can see a stellar form image in black, and some annotation in x, y, d, w , r . x and y are just that we use in cartesian coordinate system; and d is the maximum dimension of the image, which is the span of the particle projected onto a line determined by a least-squares fit of the x and y positions of all occultations; w is the span of the particle projected onto the line perpendicular to that used for d; and r is the correlation coefficient from the least-squares fit. The data of the image is structured in an array with 0 and 1, which is very easy for me to get the dimension in x and y direction. But i really don't know how to get the dimension d, w and r in least-squares fit methods. If i want to realize it in labVIEW G language, can you give me some tips or codes in LabVIEW. Thanks!

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

I am trying to drive a proportional solenoid valve: PVQ-33-5G-23-01N ( which responds to currents between 100mAand 165mA. I am using a circuit similar to the one in the attachment below except that I am using the myRIO's DAC in place of the AD5446, the LM324(http://www.ti.com/lit/ds/symlink/lm124-n.pdf) in place of the OP1177 and the MOSFET(http://www.mouser.com/Search/ProductDetail.aspx?R=VN3205N3-Gvirtualkey68900000virtualkey689-VN3205N3-G)[/url] So the challenge I am having is how to configure the circuit in labview. I am trying to use the default FPGA person ality of myRIO. I am supposed to generate a 1.2V Vref signal into the pin 3 of the LM324. By varying the word that is sent to the LM324, I am supposed to effectively vary the current on the Drain terminal of the mosfet. I have wired the Vref terminal to Connector C/AO0 on the myRIO and I have the VI below but I have no experience sending bits and bytes. I would love to drive the solenoid with about 10 -15 steps of current. Any help would be appreciated.

I have a C# code which I have compiled as a DLL class. It basically employs a Kinect camera to track an object and then spills distance of the camera from the object to a console window. How do I retrieve the distance (given in the console window when I run the C# executable file) by calling the .NET assembly in labview. Thank you!

Dear all, I have not been posting here for a while (Yes, I was an active member here). I hope all of you doing well. I am setting up a forum which it would be good if you are willing to make a few posts. It is not directly related to LabVIEW, but it could be a platform to run Labview in the future. I am talking about Project Ara. Please also feel free to put a couple post in Ara PUB. I copy the idea of Lava Lounge. Once more thing, the forum has money prizes and lucky draw. I hope that you will enjoy it. http://www.projectaratalk.com Superhero

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

I want to load hex file into avr microcontroller using labview...How it is possible?? Details-----atmega64 controller based avr kit ..and it has USB interface for programming ....I load program using winAVR but now i want to load hex file using labview ..

When I originally selected the name for my blog ExpressionFlow back many years ago, what I had in mind was functional dataflow programming and the ability to pass any subdiagrams (expressions) around as first class citizens of the language. Functional programming languages (haskell, clojure, lisp) have a lot in common with dataflow world. In principle, calling a function in a functional language is identical to calling a node in a visual language. Passing data between functions happens in an immutable way in functional languages, similar to the concept of data flowing between nodes in a flow-based programming languages. Monads determine execution order of functions with side effects, the same way as flow diagrams determine the execution order of nodes in LabVIEW. Functional programming is often seen as an alternative to object oriented programming. One can solve similar problems of dynamic dispatching either by passing functions around or passing objects with methods around. There are of course multi-paradigm languages supporting both objects and functions like Clojure and Scala. So what would LabVIEW look like if it supported concepts of functional programming paradigm? I posted an article on this on ExpressionFlow and I am intending to study the concept on ExpressionFlow in my future posts. Would you use functional LabVIEW if such a language existed? My post on how a functional programming could appear in a visual dataflow language: Synchronous Functional Dataflow Programming & Closures of Named Functions p.s. See Joel's quick intro to functional programming if you are unfamiliar with the concept of functional programming.

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

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 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!

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

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
