Convert cvi to labview

I have some C code that was developed using LabWindows/CVI and is controlled with TestStand 3.1. We also have some new development that we want to begin soon. Both efforts are do a great deal of communiction with hardware and test equipment. We'd like to use LabView on the new development. My questions...
1) What types of issues should we expect to encounter if we try to convert the CVI / TestStand effort to LabView.
2) Does it make sense to do this, or should the CVI tests (currently in a DLL) remain and should the new tests be written in LabView (RealTime) and all tests coordinated through TestStand.

The only way to convert CVI to LabVIEW is to use Tools>Instrumentation>Import CVI Instrument Driver. However, all this does is put a LabVIEW wrapper around the CVI DLL so the conversion will gain you nothing. The only real conversion is to completely rewrite your CVI functions in LabVIEW. I freely mix and match TestStand steps types with no problems. Some are CVI DLLs, C++ DLLs, LabVIEW DLLs, and some are LabVIEW VIs. I'd focus on the new development.

I would like to read a text file in which the decimal numbers are using dots instead of commas. Is there a way of converting this in labVIEW, or how can I get the program to enterpret the figures in the correct way?

The program doest enterpret my figures from the text file in the correct way since the numbers contain dots instead of commas. Is there a way to fix this in labVIEW, or do I have to change the files before reading them in the program? Thanks beforehend!

You must go in the labview option menu, you can select 'use the local
separator' in the front side submenu (LV6i).
If you use the "From Exponential/Fract/Eng" vi, you are able to select this
opton (with a boolean) without changing the labview parameters.

DC to DC converter basics using Labview on FPGA Control with VHDL

DC to DC converter basics using Labview
I am fairly a novice, that is why simplifications required, before I begin thanks in advancefor them who will response
I am designing a DC to DC (Intermediate Bus Converter, a step down BUCK converter, of 24 v input and output 9 v and 5 amp current output), using FPGA controller, I need to program this using VHDL, for which I take LabVIEW, but as I am new so do not have any idea as what are the steps that I need to take for implementation, what types of function that FPGA does in this so that it can generate 24 v and what other mechanisms that have to control inside or outside of FPGA programming and designing that it can give the desired output voltage, if you have any idea about this then I would be glad to receive the steps that are necessary to complete this

NI supports two Spartan 3E products through either LabVIEW FPGA or MultiSIM, the Digital Electronics FPGA Board (http://sine.ni.com/nips/cds/view/p/lang/en/nid/207010) and, if you are in academia, the Xilinx Spartan 3E XUP starter board (as linked by Dennis_Knutson).
Also note that if you wanted to implement some logic in VHDL and have access to that logic in a LVFPGA diagram, you could utilize the Component-level IP (CLIP) fuctionality (http://zone.ni.com/reference/en-XX/help/371599G-01/lvfpgaconcepts/using_component_ip/)

LabVIEW Interface Generator for LabWindows/CVI Instrument Drivers
System Requirements
NI LabVIEW 7.1 or later
Windows 2000/NT/XP
Use the LabVIEW Interface Generator for LabWindows/CVI Instrument Drivers to create LabVIEW VIs for VXIplug&play and IVI-C instrument drivers from function panel (.fp) files.
Instrument Driver Network
Before using the conversion utility to create a new instrument driver wrapper, please visit ni.com/idnet to see if a LabVIEW Plug and Play instrument driver is available for your device. The Instrument Driver Network (IDNET) provides support for more than 3,000 different instrument models from over 170 different instrument vendors.
Recommendations
This utility was created for developers of C-based instrument drivers who wish to provide a LabVIEW interface, but do not develop a LabVIEW Plug and Play driver. By developing the C and LabVIEW interfaces together, it keeps the components synchronized, and eliminates the need for customers to create their own LabVIEW interfaces. Vendors should distribute the LabVIEW wrapper files with the associated VXIplug&play or IVI instrument driver, so that end users do not have to visit multiple web sites to download the complete driver.
If you are not an instrument vendor, we recommend that you use this utility only if you have instrument driver expertise. Access to the instrument driver source code is preferred, in case you need to edit the C instrument driver in LabWindows/CVI.
After generation, the wrapper VIs should be tested with the instrument.
Instructions
Once you install the software, simply access the utility from the Tools>>Instrumentation>>Import CVI Instrument Driver...menu in LabVIEW. This software replaces the built-in tool and provides feature enhancements.

Converting Units in LabView and specifying sampling rate with Universal Library functions

Hi,
I am having trouble converting units in LabView 7.0 and having it write to a file / output on a chart in Nm instead of in volts. I can't seem to find any straightforward instructions, eventhough it seems like a simple task.
Another task that would seem rather simple is changing the sampling rate with the XAIn program from the Universal Library for LabView (this is version 5.40).
If anyone could help me out, I would greatly appreciate it - I have tried other sources without much luck!
Thanks
Jenna

Are you really needing to change units or do you need to scale the voltages read from your sensors? If it's scaling, it would be trivial to set this up in mAX or with the DAQ Assistant if you were using an NI board. Since you are not, then you could use the Scaling and Mapping Express VI. The y axis of a chart is just a label. You can use the text tool to change it to anything you want.
I have no idea how to change sample rate for your board. Have you asked the vendor?

Labview version 7.1 is too old to convert to current Labview version 8.0

I had developed my Labview code sometime back using LV-7.1 and now I am trying to deploy it on a new PC. The Test Stand version that I have is 3.1. I did everything right and after I installed my deployment package, I get the error that the Labview version 7.1 is too old to convert to current Labview version 8.0.
I am going to look into converting my code using Labview 8.0, but I am puzzled, why would it matter, as am using the same Labview (7.1) and TestStand (3.1) as before, and getting this error? I also installed the old Traditional DAQ drivers (instead of the DAQmx) and so everything is the same except that the PC is new.

Hey Shoab,
Are you getting this when you run the sequence in the Sequence Editor? If so then I would suggest checking the adapter configurations. Go to Configure>>Adapters select LabVIEW and click the Configure.. button. Once in there you can change the run-time engine to 7.1.
Let me know if that helps.

Convert vi from LabVIEW 5.0 to v.8.2

Hello-
I am trying to open a subVI in LabVIEW 9.0 but it was written for v. 5.0... someone told me that if I open the vi in a version before 8.2 and save it, then I should be able to open it in 9.0. I don't have any version before 9.0 so he suggested that I post the file on this forum... I have attached the subVI so if someone could please convert it (who has a version of LabView older than v. 8.2) it would be much appreciated!
Thanks!

I can't convert .vi from labview 5.0 to 8.6

I'm tring to convert a labview project from 5.0 version to 8.6 version. I know that direct conversion is not possible. I saw at this link:
http://zone.ni.com/devzone/cda/tut/p/id/8387
that conversion is possible by intermediate comnversion with 8.0 version (I have it).
Unlikely somethings wrong happen when I try to open my original labview 5.0 .vi with 8.0 version.
Do someone know alternative version to convert my project????
thanks in advance

From help
Adding VIs and Controls to the User and Instrument Drivers Subpalettes
Adding VIs and Controls to the User and Instrument Drivers Subpalettes
The
User Controls and User Libraries palettes
contain subpalettes for each directory, LLB, or palette (.mnu) file in labview\user.lib and icons for each file in labview\user.lib.
Save
subVIs in the user.lib directory only if they are usable, without
modification, across projects. Paths to VIs in user.lib are relative to the labview directory. Paths to subVIs you save elsewhere are
relative to the parent VI. Therefore, copying a VI from user.lib to modify it for a special case does not change
the path to its subVIs located in user.lib.
Caution Do not save
your own VIs and other files in LLB
files installed with LabVIEW. Save your controls and VIs in the user.lib directory to add them to the
Controls and Functions
palettes.
Complete the following steps to add new VIs and controls to the
user palettes.
Save the controls and VIs in the labview\user.lib directory to add them to the
User Controls and User Libraries palettes,
respectively.
Restart LabVIEW. LabVIEW updates the palettes to contain the controls and
VIs in the labview\user.lib directory.
The
Instrument Drivers palette corresponds to the labview\instr.lib directory. Save instrument drivers in
this directory to add them to the Functions palette.
Note If you add a subdirectory or LLB to the labview\user.lib or labview\instr.lib directory and the subdirectory or
filename begins with an underscore (_), the
contents of the subdirectory or file do not appear on the User
Libraries or Instrument Drivers palettes.

How to convert dasylab to labview

Hi all,
I get a project invovled a serial port reading, then use the band pass filter and FFT to process the signal. At last, locat the peak frequency of the spectrum. This project used to be achieved by dasylab as shown in the attachment. Since I am not familar with labview, can somebody please spare me several minutes to convert this program to labview VI. Thank you very much for your kind help.

As I said, images are worthless because they tell no one how you have those functions configured. If you do decide to post the actual code, then you will have to be somewhat lucky in finding someone who has both DASYLab and LabVIEW.
The Express VIs that you will want to look at include the Instrument I/O Assistant, Filter, Spectral Measurements, and Statistics. Probably just need a loop areound the Instrument I/O Assistant if you need to collect x number of points.

Try this. The error was just because the functions are part of the LabVIEW distribution and had nothing to do with converting the driver.

How to convert llb from LabVIEW version 8 to 7.1

Can someone tell how to convert the llb from LabVIEW version 8 to version 7.1?
I hope to sent the program to the others, but the other side are using LabVIEW version 7.1 but not version 8.0.
I know I can save to VI file as previous version, but it contains severals of VI in the library, it is quite time consuming.
Can everyone sugguest any method or solution to solve my problem.
Thanks.

Hi anson,
it will run also in LV7.1 - but you should check those warnings (probably things not/differently supported by LV7.1...) anyway!
