Verify Labview Vis before starting execution in release mode

I have a TestStand sequence that calls a number of Vis. When I switch from development mode to the run-time engine, sometimes the TestStand sequence crashes at certain Vis. I then find that when I switch back to developement mode and open the vi, it has a start next to the filename, which indicates that the file needs to be saved. When I save the files, that step works fine in run-time mode, but then the sequence crashes on the next step that has this problem.
How can I find out which files need to be resaved before running something with the run-time engine? Is there a way to precompile everything so this doesn't happen?

Steve,
It sounds like you are running your VIs with the LabVIEW runtime engine. For this operation, we recommend that you do a TestStand deployment using the Deployment Utility. The TestStand Deployment utility will save all of your VIs and make sure that they are packaged correctly so you can call them from TestStand without the LabVIEW development environment installed.
Please see Chapter 14 of the reference manual for detailed instructions for deployment. You also might find this knowledge base helpful: Deploying TestStand Systems

Why does my LabVIEW Run-time server return the message "source does not exist Last UI message: Start Execution"?

I am trying to build a stand-alone application on a target pc for which I have built a LabVIEW server that TestStand can use as an adapter.
In order to do this, I searched this site and found the topic: "How do I build and Use the LabVIEW Operator Interface as a LabVIEW ActiveX Run-time server?" After following the procedure to the letter, I ran the testexec.exe file as instructed and loaded my sequence file. As soon as I try to "Single Pass" or "Test UUT" I get an error which says "source does not existLast UI message: Start Execution". This error appears when running the testexec.exe file on the target pc or the development pc.
I have found though, th
at if I open the Operator interface through the Start: Programs>National Instruments>TestStand>Operator Interfaces>LabVIEW then the sequence file runs without these errors.
Any ideas why this is happening?

Hello Robroy,
The KB you mentioned explaines how to build the LV Operator Interface (OI). So, I assumed you built the LV OI and also configured the LV adapter to use the TestStandGUILVRTS server without problems.
The error you are getting may be due to missing VIs. In other words, the LabVIEW OI may not be finding all the VIs your sequence is calling.
In order to deploy sequences that call VIs, you need to first run Tools >> Assemble VIs for Runtime Distribution. This tool gets all the VIs your sequence needs and saves in a separate directory.
For more information, you may check the TestStand User Manual chapter 17, it describes how to distribute TestStand and sequences.

Advice about application structure before starting

Hi all,
I am so sorry for this longest post, but I have to explain all thing. Sorry again.
I have been studying with Labview for a year by myself without taking any professional support. When I get stuck in preparing my VIs, I always post here and you answered me with great patient. Thank you for all. Now, I am about to start a new VI and before starting it I thought it would be good to consult you on that.
The goal of this VI could be classified under 4 main topics: Acquisition, control, analysis, and recording the data. I am studying on a test system. There are two types of data to be acquired from the test system: pressure and temperature. For this purpose I have 1xNI 9203 (analog input-current) & 2xN9214(analog input-temperature). The test system is desired to be under control by use of a DC compressor with a frequency converter. To control that frequency converter I have to use NI 9263 (analog output- voltage). All hardware system is installed on NI 9188 cDAQ.
Before preparition of this system, I have coded a VI that acquire, analyse, and record the data-there is no use of NI 9263 (attached here). In this VI, I used a basic structure and it works fine. The only problem of this VI is delaying when the stop button is pressed. Anyway, now I want to prepare a new one. The difference of the new VI from the old one is that it controls the system while acquiring, analysing, and recording processes. And this control is supported by acquired pressure and temperature values. This will be my first big project and I need your suggesttions on structure of this VI. Do I start to build it with state machine architect or another ones? To prevent the data loss what kind of precautions could be taken?
Thank you all in advance.

Egemen,
First, Great! It is very important to plan and design your program before starting to write it.
Next, you do not need to apologize for providing the information necessary for someone to respond to your request. We would very much prefer a post of several paragraphs which contains the relevant information to a brief post which only elicits questions for more details.
Now to your questions.
1. Look at the style guides. Your block diagram was several screens high and wide. It is recommended to keep the diagram to one screen. Paticularly in programs which will get large and copmlicated like yours, this readability constraint will be very worthwhile. Effective use of subVIs is one way to help minimize screen bloat.
2. Look at the style guides. The use of local variables to pass data from one loop to a parallel loop is not recommended. It can lead to race conditions, force execution of the loops in the UI thread, and is slower than wires.
3. Read the help on Event Structures. Only one event structure per VI is recommended. Although the way you have used them will probably work, it consumes hectares of block diagram space and may be vulnerable to problems when you or another developer decides to make a few changes.
4. Because there is no data dependency, it is possible (although not very likely) that the main loop could start running before the clear history property nodes execute.
5. How do your temperature charts know which waveform to display?
6. You stop on DAQ errors but do not check for file errors. You may want to consider more robust error handling.
Now, some general comments on program structure. You list 4 topics: Acquisition, control, analysis, and recording the data. This may also be a good way to think about program structure. The structure probably needs one more topic: User Interface. The program you posted essentially has 2 topics: User Inputs and everything else. Think about the timing requirements for each topic. User interface - needs to respond to user inputs in about 100 ms or the user begins to feel as though the program is not responding. Similarly, displays do not need to update more than a few times per second. Acquisition - Software timed. Default value = 1.67 Hz. Output not specified, but since you are talking pressure and temperature, it is probably slow also. Once you start doing closed loop control, it may become more important to keep the timing constant. Record data - same timing as acquisition. However, writing 8-64 channels of data two two files twice per second may not be optimum. And what happens when the OS finds that the files are fragmented and must allocate new sapce for the file and takes more than half a second to do so? Analysis - Your subVIs were not included so I have no idea what they do, how fast they may be and what effects they may have on the overall operation.
What I suggest is that you study the Producer/Consumer Design Patterns and State Machines. I think you may end up with 3 or 4 parallel loops. One will be the User Interface loop with the only event structure. Another will handle all the data acquisition (possibly including outputs when controlling your test system). This will be a state machine which initializes the DAQ, Reads and Writes, and shuts it down when finished. The File writes may be in a separate loop. If file I/O is put into a parallel loop, it should be a state machine which opens, writes, and closes the files and retains the file path or reference for repeated writes. The control and analysis (another state machine) may be in a separate loop or could run in the timeout case of the event structure in the UI loop. Which is best depends on details of your system.
With the amount of data you are moving around and the number of property nodes you need to use, learn to manipulate the front panel from a subVI. Search the Forum for posts on use of control references and on updating the main front panel from a subVI. There are some good methods posted.

Where can I find example LabVIEW VIs for the NI-USRP?

There are several sources of example LabVIEW VIs for the NI USRP:
We have established a NI Community "NI USRP Example LabVIEW VIs" where you can find example VIs from us (NI) and the community.
The NI-USRP driver installs a variety of example VIs to the to the following folder on your PC:
<LabVIEW Installation path>\examples\instr\niUSRP
where you should replace <LabVIEW Installation path> with the root folder of your local LabVIEW installation. For instance, my Windows 7 32-bit PC here has LabVIEW 2011 installed and the examples can be found here: C:\Program Files\National Instruments\LabVIEW 2011\examples\instr\niUSRP
I've installed the NI-USRP driver, but I can't seem to find the new examples in the LabVIEW Example Finder. Where are the example LabVIEW VIs installed by the NI-USRP driver?
Although the NI-USRP driver does indeed install examples, the current NI-USRP 1.1 release does not update the LabVIEW Example Finder with entries for these examples. To find the examples, you can navigate the Windows Start Menu to the following location:
Start Menu\Programs\National Instruments\NI-USRP\Examples
This Start Menu entry includes several Shortcuts that point to folders that are the home to example VIs.

Hello,
It looks like Agilent/HP makes the 8990A, but I was not able to find a driver for it that we or Agilent has written for this device.
Since I am not familiar with the 8990A, I cannot recommend which drivers might be similar, but you are pointed in the right direction. Agilent themselves might know more about which models use similar command sets so that you can modify a driver easily.
Hope this helps.

Integrating Labview VIs in Labwindows

Hello,
I have a question that is partly related to Labwindows, but I hope this is the place to post it, since it is also linked with Labview.
During the last months, I have made several VIs to control different instruments and generate reports with the data adquired. Nowadays, I would like to integrate all these VIs in a big Labwindows program that would control everything, so I am thinking of different ways of doing it.
I would like to run the Labwindows program, and when I want to start the experiment, all the different VIs should start to run. Should I make a call to the different .exe or use .dll? When the experiment is finished, then all the VIs should stop and close, and then I am thinking of using shared variables to send the stop information. Do you know any other way? Will it work?
I want to make it as simple as possible, because the program is going to be run by an operator and he would prefer just to press one button and not open different programs/windows.
The reason because I ask all these questions is because I prefer to do a good plan before starting with big modifications, so sorry if they are too silly!
Many thanks

Hey,
I would create DLLs out of the VIs and call them in CVI.
To create an extra VI or exe which handles the SubVIs and communicates with CVI would be more work and not that elegant, since you need to start the executable somehow next or within your CVI code.

Labview VIs for HP 35670A

The link to the labview VIs for the HP 35670A is no longer valid and the search for the same returns nothing. Does anyone have the Labview VIs for that instrument?
The last post was back in 2004(see below)
The instrument driver for the HP 35670A is only
supported under LabVIEW 6 and 7. You should upgrade to the latest
version of LabVIEW in order to use the HP 35670A driver or any of the
newer drivers that we release in the future.
The instrument
driver for the HP 35670A can be found on our web site at

Why don't you go to the Instrument Driver Network? I don't know what kind of search you did but the driver is certainly still available and can be found by using the search option there.

Calling labview VIs from python in Linux

Hello.
I've spent some time searching for this but I haven't found exactly what I was hoping for.
I'm involved in a project that we're starting now and it involves creating a complex software architecture in order to control a robot. This software will need to perform multiple tasks such as interfacing with hardware (which LabView is perfect for) as well as planning and high performance image processing (which LabView isn't as great for).
I was hoping to be able to use a scripting language like python to manage high level stuff (planning, behavior, etc) by calling "subroutines" in other languages such as C++ for the high performance stuff and LabView VIs for the hardware interfacing. I would also like this to run on Linux.
I've found a lot of suggestions on how to call Python scripts from within LabView but this is not what I want. I want exactly the opposite, invoke VIs from Python. I found some information on how to do this on Windows (http://zone.ni.com/devzone/cda/tut/p/id/5719) but this article seems to assume that Windows is being used.
Does anybody have an idea on how to do this?

Unfortunately that's not an option. This is an interdisciplinary school project involving students from engineering (mechanical, electrical and more), computer science and more fields. Some of these students have gotten used to using Labview and this is the main reason I'm trying to accomplish this. I want to have the higher level architecture done in a scripting language such as python which will enable us to create modules in various different environments such as C++ for tasks requiring high performance (image processing for example), Labview for tasks that the people used to using that and even something running on the GPU if there's use for that. Python would make it easy to glue all these components together while maintaining an environment that would make it very easy to configure the whole software system in different ways.
I'd also prefer that this all run on Linux.
The more I look for this the more hopeless I get I'll find anything which is very frustrating. It's a bit hard to believe that Labview doesn't have "python bindings" for running the VIs from within python :-(

Logging data in a file using Labview VIs vs. Mathscript functions.

Hello,
I'm working on a data logger at 200 Hz frequency. I wanted to log the data to a file after eace sample received. When I used (fopen,fprintf,....) on Mathscript, the Labview started to log the data at a slower rate. I then used the Labview file VIs and it is working fine up till now.
My questions are as follows:
1- Are the file functions in the Mathscript slower than the Labview VIs ?
2- Is saving the data to a file after each sample is received a good idea or is there a better idea ? I just don't want to keep the data in the memory and after all the data is logged, I flush them to a file ... because, it seems that the PC will run out of memory.
Thank you,
Walid

Yes. That's because you're going through another layer of software. Why were you trying to use MathScript to log data to file in the first place? Are you a Matlab "aficionado"?
2- Is saving the data to a file after each sample is received a good idea or is there a better idea ? I just don't want to keep the data in the memory and after all the data is logged, I flush them to a file ... because, it seems that the PC will run out of memory.
It doesn't make sense to save data after each sample. File I/O is an expensive operation in terms of time, and you have the operating system to deal with, so while you may be able to keep up the rate for some time, eventually it will be thrown off. You can do as suggested which is to wait until you have a certain amount and then write that to file, or you can set up a producer-consumer or master-slave architecture. Let one process/loop collect the data and put into a buffer, like a queue, and the other process/loop can stream it to disk at a more reasonable rate. You just have to make sure the buffer is large enough so that if the file I/O gets hung up you won't reach the buffer's limit.

Lion or Snow Leopard? If Lion, boot into your Recovery partition (hold down the Command and R keys whilst booting) and use Disk Utility to verify and, if needed, repair the boot volume.
If Snow Leopard, use the installation disc and use Disk Utility in the same manner.

further to Limo2kz's problem, LAST_INSERT_ID() will return 0 if the last INSERT statement actually has inserted 0 records. this could happen if the previous INSERT attempt has failed.
as far as i can remember, you should find out if the account or user that you are currently using to connect to MySQL database is allowed to do more SQL executions and create more SQL connections at certain given time (i.e., 10 executions in 1 hour, 10 connections in 1 hour). otherwise, you would have subsequent SQL exceptions because the database server won't allow you to execute them, thus giving you a null ResultSet.

How to use Modal Parameter Extraction Labview VIs

Hi KCMTM,
My name is Yusuke Minami, Applications Engineer, NI Japan.
I'm so sorry, but the "Modal Parameter Extraction Labview VIs" is not supported by LabVIEW 2010.
Since it will unlikely be updated for 2010, we have to ask you to install LabVIEW 2009 with the LabVIEW Advanced Signal Processing Toolkit and LabVIEW System Identification Toolkit in order to use the package.
Although I cannot guarantee, but I'll send an update request to the R&D.
I deeply apologize for the inconvenience.

Gnome/GDM Issue - System freeze before starting Gnome every reboot.

Hi guys, sorry for my bad english.
I've a strange problem with Gnome/GDM DE.
Yesterday, I have installed gnome on my laptop but it works 1 times every 2.
The first time i power on my laptop it works, the second (or if i try to reboot) it freezes before starting GDM.
I can't switch tty, can't shutdown. I can only power off pressing power button.
How can i solve this problem? Anyone had this issue before?
PS: (I've installed arch yet on the same laptop using XFCE without problems)

Verified by visa does not work

When trying to use Verified by Visa, it no longer recognizes our password. Instead, it allows you to try to provide the password 3 times. It then locks out and forces us to reset the password. This new password then works for the one transaction being authorised, but will not work on any subsequent transactions. Rinse. Repeat.
This problem appears different than the 'mixed frame' or 'blank pop-up' problems other users have reported with this same authentication system. Tracking back some of the suggest modifications on 'about:config' on SSL and trusted negotiation modifications, none of them appear relevant (i.e., all the switches are set as the web suggests they should be).
It also feels like this problem only was introduced recently after a Firefox update.

Is there any possibility in LABVIEW to Create a release mode EXE like VC++

iam krishnaprasad. iam new to LABVIEW.
i have 1+year experiance on VC++6.0.
Is there any possibility in LABVIEW to Create a release mode EXE like VC++ .
if there please suggest me how to create it..
Solved!
Go to Solution.

First, you must include you VI inside a LV project. This can be done automatically by selecting New Project from the Files menu in that (any) VI.
LV will ask you whether to include any open VI to be added to this newly opened project. Click Add & thats it. Now save this project in a location of your preference.
Then, in the Project Explorer window, right click Build Specifications >> New >> Application (EXE) or Installer, as per your requirement.
The former will create you an EXE only while the latter will bundle all that needed for an installer (mainly LV run-time engine of the version under use).
If you create the EXE alone, then you need to install the LV run-time engine of the corresponding version manually in the target PC first, before trying to run you application (EXE). Else, it will throw error & wont run properly.

Although it keeps actively finding problems with the disk, the progress bar hasn't changed for more than a half an hour, and it still says it's going to take an hour and 35 minutes. I'm starting to worry it will never be done! My laptop, a Macbook Pro, is pretty old - about five years, and I don't know if the fact that I've never run a verify disk permissions before has anything to do with it.
The only non-greyed out option is to currently 'stop permission verify'.

Just let it run, it probably won't take that long. Also you may benefit from reading Disk Utility's Repair Disk Permissions messages that you can safely ignore.
