Software Integration in LabVIEW

Is it possible to integrate outside software packages in labview?
For instance, I want to run an off-the-shelf image and audio processor, and I want to import the data from there and into LabVIEW, and then stored.
Is that possible?

parser;
There are example on how to incorporate voice recognition software into LabVIEW. Visit the following link:
Voice Recognition in LabVIEW
IMAQ will do the job for image comparison. You will gain better insight if you post your question in the Vision forum. There are other softwares that integrates to LabVIEW too, like IVision.

PVCS version control integration in LabVIEW?

I am currently using the free 2 client Perforce software with LabVIEW. It works well for my needs, as we have only 2 developers working on this project. However, we were just got bought out by a larger company that uses Serena PVCS for their version control. We are transitioning to their IT system and I need to transfer everything to a new server anyway, so was considering trying PVCS instead.
I would love to hear about anyones experience with PVCS integrated with LabVIEW? Or even better, if anyone has the experience to compare PVCS with Perforce in terms of LabVIEW integration? I need to weigh the two options.
Thanks for your help!

Nothing much yet, but I found a website that has the batch file for integration with SVN.
Guess I have to contact the author to get more details:

I have found a person who has a driver software to connect Labview with PCI card. But he says that i need to download a freeware software to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ??

I have found a person who has a driver software to connect Labview with a general PCI card. But he says that i need to download a freeware software from NI website to configure the PCI card. But you have mentioned that freeware is for GPIB boards. Is it correct ?? Is there any other way out ??

I would ask the person who told you about the freeware software to help you find exactly where it is. I am not aware of any freeware software for configuring motion PCI cards but maybe the person you know might be able to help you locate it.

Is it possible to invoke other software applications in labview?

Is it possible to invoke other software applications in labview? I would like to upload my files processed in Labview to my web based database. I have no basis of FTP and SQL. Providing that I have no Internet Database Toolkit installed in my computer. So, is it possible to "call" the software in Labview, just like calling a function or sub VI?

Hello kaykeat,
It is definitely possible to call other applications inside LabVIEW. Please see the links below for more help on the most common ways to call external programs.
If the code is a shared library:

Changing a software into a Labview Programme

Hi all,
I am new to LabView and would like some help in changing a software into a Labview Programme.
The PC software is a platform that enables a PC to control a R/C transmitter. It is written in C# therefore I need to change it into LabView for my project.
For more information about the software you can download it from the following link: (http://www.min.at/prinz/?x=entry:entry130721-182227)
It is under the PC control software section.
Thanks for all the help!!!

Welcome to my world.
I have been working on a project (not a school project, a work project) for a while now to emulate a set of C/LabWindows programs to LabVIEW.
"Why?" RavensFan asks. Because the software on the instruments we build needs rapid updating as the instruments are updated, doing this in C is always a major task (it is thought that using LabVIEW should [eventually] be quicker and less prone to error), and we are a small company which cannot afford the luxury of a staff of C and/or LabWindows programmers.
But what RavensFan says is true. You have to figure out exactly what the C# program does and how to do the same thing in LabVIEW. You cannot do a transliteration by any means, it will come out like some of those old Japanese instrument manuals transliterated into English, and have just about as much use (i.e., none). But you have at least one thing in your favor, quite a bit of the C# code functionality can be replaced with very simple LabVIEW code.
As to understanding the C# code, well, you just might have to grab one of your buddies and bribe him with pizza (the Universal Currency for students) to walk through it with you until you can understand the flow of the program. This may take more than one pizza and/or night.
One thing, remember to make your LabVIEW code modular (i.e., using subVIs for common tasks) so you can (1) fix one bug and have it corrected in many places at once, and (2) build VIs which don't take up acres of screen real estate - there is little that is so frustrating (to me, anyway) as having to skip back and forth over a 9000x2600 pixel screen to troubleshoot code.
Best of luck,
Cameron

Problem in a particular scan of our software designed using labview

We are using a software called CROP for our experiments . The software is designed and bulit using Labview . The software seems to be running fine but there is a problem in one of the scans that we use in the software . The particular scan called the 'Threshold Scan' is coded in such a way that it increments by itself to a certain value of voltage after the scan has been conducted at the current voltage for a certain period of time . For example the current value is 30 and increment is 30 and the final value is 300 for a time period of 1 minute . The scan automatically increments from 30 to 60,60 to 90 and so on after each minute till the final value of 300. The problem is this scan seems to be running perfectly fine in two of our windows 7 lab systems but elsewhere in all other systems running windows 7 (or) 8 it blanks out after the first value of voltage and stops abruptly (i.e) in this case it stops at 30 and does not increment and perform the scan for each voltage till 300. The code seems to be perfect and it has been hard to figure out why the scan runs perfectly in two of our lab systems and does not do so in any other system.

Hi raj177,
Looking over your code I don't see anything glaringly obvious, but not having all of the sub-vi's makes it hard to thoroughly explore. That being said, I do have some troubleshooting steps we could start with.
Have you tried probing the starting, ending and increment voltages coming out of the "threshold wizard" sub-vi while the code is running on the troublesome machines? Also, canyouprobethe "# ofpoints" wire?
The measured values will help us determine whether the problem is inside or outside of the for loop.

Is there any example for a software transceiver in labview / labview modulation toolkit ?

hi everyone
i am sure you have heard of this a lot ..... but i am new (like 20 minutes old) to labview. i am quite fimiliar with matlab and other programming languages. i am doing a project based on software defined radio. for that i understood an example demo from matlab where a fully functional software transceiver has been built as an example.
now i myself have to do that in labview for the sake of comparison and better real time compatibility with USRPs. i am just getting started and was hopping if there is a similar example in labview or someone else's project. i have installed the modulation toolkit and have gone through its various blocks. i understand that i can build a tranmitter and receiver from scratch but that would take a lot of time and testing. so can anyone help me out in any way.....?
regards

Third Party Recruitment Software integration with SAP HR

Dear Experts ,
Iam given a scenario where in the client wants the Erecruitment software Taleo to be integrated with SAP HCM.The HR recruiters/Managers are currently hiring them into the taleo software and from there the data need to be pushed to the SAP employees's infotypes.
In Addition to this the benefits infotype need to be maintained automatically in the system.Is there any way to automatically default the benefit infotype also
Kindly suggest a solution for this.
Regards
Gopa

You will need interface(s) between Taleo and SAP....If Taleo is your recruiting system...then they may want...
Outbound from SAP: Interface that sends them vacant position data from SAP (you need this so that when Taleo sends you finally an employee data after hiring they can send you the position data with it).
Outbound from SAP: You may also need to send them terminations from SAP (optional - may be needed depending on your company process for handling rehires)
Inbound to SAP: This is the main file from Taleo after offer is accepted and employee is hired in Taleo. At this time Taleo will send you a file for which you can write an interface to hire these employees into SAP. You can do a BDC session with PA40 - you may have to determine if its a hire or rehire here. If you are processing payroll then its important to make sure you have all the payroll related info types (if they are not coming from Taleo then you should at least have them defaulted to what your client agrees).
The second part to your question
Creating benefits depends on how you are getting or determining benefits data.
1. Benefits configuration has something called automatic/default plans...
>>> "Automatic" plans are something employee is enrolled into and has no option to change them.
>>> "Default" plans are something employee is enrolled into on new hire and typically has 30 days to make changes...this is standard configuration for each plan and should be completed.
If it is controlled via benefits config then you just need to go through hire action...and typically as part of that hire action - IT0378/IT0171 will prompt you to go to benefits enrollment screen and enroll employee...into these automatic/default plans...plans will be pre-selected based on configuration. So all you do here is hit save and continue with rest of hire action. All this is recordable via BDC session.
2. If it is NOT controlled via configuration...and you are getting benefit plan details in the file then you just create them in the corresponding info types...IT0167/0168 etc. For processing sanity I would separate hire and benefits creation as two step process if all the data is coming via files...
Happy interfacing...

Digital barometer to be integrated with Labview programme

Hi,
Does anyone have any recommendations for a digital barometer that could be integrated into an existing NI data acquisition system and Labview 8. Ideally I'm looking for a barometer that can connect to the acquisition hardware we have currently and provide a real-time readout of the ambient pressure within the Labview VI we have currently (obviously some modification to this would be required). I've had a look around the NI website and can't find anything suitable, and Google turns up far too many results.
Apologies if this is in the wrong forum - I was unsure which would be the best place for it.
Thanks for your help.

Dear Thomas
Can I ask what acquistion hardware you have first of all? A barometer measures the static DC pressure and a recommendation I have is to use a compactDAQ or compactRIO board using a C Series Module; preferably a NI 9237 or NI 9219. Both the NI 9237 and NI 9219 modules can power strain gages or pressure transducers.
A good link to the pressure sensors we have can be found here:
http://zone.ni.com/devzone/cda/tut/p/id/3639
Please let me know what acquistion hardware you have and I can advice how best to set this up.
Many thanks for using the NI forums and I look forward to your reply.
Kind regards

Which software, c++ or labview..., for high time-resolution( µs)?

Hi,
i need to measure data with a time resolution of less than a few microseconds. Is this possible with labview? Or will i have to use C++?
The interface cards, i could use are: CB-68LP or BNC-2120 both from national instruments
Thanks
Alex

Alex,
As the data acquisition is not timed by the software but by the hardware that you are using it doesn't matter which programming language you choose for your task. By the way, you have just provided information about the external connector blocks but not about the data acquisition device that you will use
LabVIEW is capable of analyzing continuous data streams with several MB/second which is comparable to C++ so I don't think that this will be the main criteria to decide which programming language to choose.
You should choose whichever approach is more appealing to you (graphical or text oriented). In my opinion the graphical approach is more intuitive and faster and it's easier to maintain code that was written some time ago but I don't want to start a debate on principles with this statement.
If you prefer the text based approach please have a look at NI's Measuerement Studio which provides great features for user interface design, signal analyzing and data acquisition.
Best regards,

DeviceNet .dll firmware integration into Labview

Hello all,
i have been charged with integrating DeviceNet on our new calibration system. Unfortunately, the company acquired a DeviceNet interface module from a vendor that does not include Labview interfacing VIs. I am therefore experiencing quite a lot of trouble integrating the firmware .dll. The vendor told me that it will take a while before they can help me.
I have succeeded at running some of simplest commands from the header file (ie open and close Api). However, more complicated commands, such as searching for nodes on the network, and explicit messaging are not working. This seem to be mainly caused by the way i input structures into the call library function node.
Can anybody tell me how to structure my inputs for these functions?
included are the header, the .dll and my own (clumsy) attempt at making the vi to call the functions.
thank you for your help

Yes, you're right. Those inputs are not exactly what is expected. However, where i encounter the most seriuos problems (up to and including Labview crashing) is when i have inputs consisting of structures defined in the header file. One example is the GetNodeList method, which expects a pointer to a structure called TNodeList, defined as:
typedef struct
BYTE byCount;
TNodeDesc NodeDesc[64];
} TNodeList;
where NodeDesc[64] is an array with 64 entries where each entry consist of the following structure:
typedef struct
BYTE byMacId;
WORD wVendorId;
DWORD dwSerial;
} TNodeDesc;
I am unsure how such structures are defined in LabView for the "call library function" node.

Marc Fornes-Mora

Editing a software created with labview

Hi
I have a software which was created using labview. it is basically a sofware to control a laser machine used for material deposition. i also i have the source code for the software. I want to make some modifications to the program. When i make some changes in the source code. i see that there is no change in the actual software which is an exe file. so how can i overcome this problem? I guess once i make the changes to the source code I need to create a new excecutable file from all the VI's. So I want to know how can i make a new exe file from the changed VIs.
I want to know what is the difference between the following
.vi file
.llb file
.lvllb file
Thanks in advance
Vikas
Solved!
Go to Solution.

Vikas,
when working in LV, you have an edit time compiler, compiling you source code (the block diagram) into executable code. Still, you need the developement system to start the execution of this code.
Therefore, you will create a *.exe file out of your application when finishing all changes in order to execute the application without the need of the developement system (still you need the LV Runtime Engine).
VIs are the modules in LV and they consist of three parts stored on disk:
a) Frontpanel, the interface (IO or user interface)
b) Block Diagram, uncompiled sourcecode
c) compiled sourcecode
LLBs are the old version of LV libraries:
+ free naming (obsolete since break up of 8.3 naming convention)
+- VIs contained in the LLB are slightly packed
+-single file (good for deployment, bad for SCC)
lvlibs are new LV libraries:
+ lvlib-file is XML based "filehandler"
+ namespacing allows same VI names in memory (still bad idea for disk!)
+ VIs know about "their" lvlib
- Under certain circumstances maybe a little confusing for deployment
hope this helps,
Norbert
