How to interface data acquization card(DAQ) with labview

I want to take input from labview and display it on labview envioment .all the inputs are digital and change the state of switch according to the input.

What exactly is your question? Do you have a DAQ board or are you looking for a recomendation on what to buy? If you already have a DAQ board, is it one from NI? If so, what model#? If using a NI board, you should start here. There are also a large number of shipping examples in LabVIEW related to DAQmx.

How interface N5181A MXG signal generator with labview by using LAN Interface????????????

hai every one ...i have a doubt how to interface N5181A MXG signal Generator with Labview by using LAN Interface???? and
how to find IP Address of N5181A MXG signal Generator????????
when i connect instrument with labview it shows that no instrument connected and what are the requirements for LAN interfacing with that instruments in labview and please help me??????

You can set the IP Address on the instrument. You may need to be in the same subnet of your controlling computer, so you may need to set your computer's IP Address to something static.
Use VISA. It makes life easier if you decide to use another bus (like GPIB, USB, serial, etc). In MAX, create a network session with the static IP address you set the instrument to and use that as the VISA Resource.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to input data into a table with columns?

I am trying to input data into a table. My table have 5 columns and an unlimited amount of rows. I created a program in LabView that enters the data into the table but it enters all of the data in one row. I would like to enter the first set of information into the first column, the second set of info into the second column and so on. I am including a copy of the program that I am working with. I would like the number of runs to be put into the first column (it should count down like number 5 in first row, number 4 in second row, number 3 in third row, and so on). I would like the applied voltage to be placed in the second column, and so on. Any help or information will be greatly appreciated. I am working with LabView Version 6.1 and 8.0. I am submitting the vi from 6.1.

Pondered,
I looked at your code and I think you might be making things too complicated. I've included a very simple example that demonstrates how to write a 2D array of integers to a table. Hope you find this helpful. It is in LV 7.1.

How to insert data in a column with uniqueidefier data type

Guys,
I need insert data in a column with uniqueidefier data type, when i am trying to that getting error.
error message says: "Conversion failed when converting from a character string to uniqueidentifier."
I have data in table a col1,col2,col3,col4 - col3,col4 has datatype as varchar and i am updating table b columns col1,col2 with table a col3 and col4.
Please guide how to do it.

Hi,
Not any String can be convert to uniqueidentifier.
1. you have to make sure u use a value which is fir to be uniqueidentifier
2. Use convert or cast in the insert query in order to convert the string into uniqueidentifier
insert X ... convert(uniqueidentifier, 'string which fit to be convert to uniqueidentifier')
Please post DDL+DML for more specific help
DDL = Data Definition Language. In our case that is, CREATE TABLE statements for your tables and other definitions that are needed to understand your tables structure and there for let us to test and reproduce the problem in our server. Without DDL no one
can execute any query.
How to get DDL: Right click on the table in Object Explorer and select script table as CREATE. Post these create table scripts here.
DML = data manipulation language is a family of queries used for manipulating the data it self like: inserting, deleting and updating data. In our case we need some sample data in order to check the query and get result, so we need some indert query for
sample data.
If you post a "create query" for the tables and "insert query" with some sample, then we could help you without Assuming/Guessing. There is a reason that DDL is generally asked for and expected when discussing query problems - it helps
to identify issues, clarify terminology and prevent incorrect assumptions. Sample data also provides a common point of reference for the discussion. A script that can be used to illustrate or reproduce the issue you have, will encourage others to help.

How to import data from CSV file with columns separated by semicolon?

I migrate database from MS SQL 2008 to ORACLE 11g
I export data to CSV file from MS SQL
then I try to import it to Oracle
several tables goes fine using Import data option in the SQL Developer
Standard CSV files with data separated by comma were imported.
chars, date (with format string), and integer data are imported via import wizard without problems
the problems were when I try to import table with noninteger numbers with modal part separated by comma not by dot
comma is the standard separator for columns in CSV file
so I must change the standard separator to semicolon
then the import wizard have problem to correct recognize the columns data because it use only standard CSV comma separator :-/
In SQL Developer 1.5.3 Tools -> Preferences -> Migration -> Data Move Options
I change "End of Column Delimiter" to ; but it doens't work
Is this possible to change the standard column separator for import data wizzard in SQL Developer 1.5.3?
Or maybe someone know how to import data in SQL Developer 1.5.3 from CSV when CSV colunn separator is set to semicolon?

A new preference has been added to customize the import delimiter in main code line. This should be available as part of future release.

How to creat the interface of auto CAD file with labview

Hi
I have been controling 2-axis Piezo motor with labview. Now I have to use the dwg or dxf file to move the piezo controller axis. How I can transform the dwg or dxf file into decimal number 1, -1 to create interface with my labview.

Hi Nusrat,
So it sounds like you want to create a CAD drawing and then control your piezo motor via LabVIEW by moving the CAD drawing? Is that correct?
If that is correct - I don't know of a way to do this I'm afraid. I don't think it's really possible.
The only potential way to do this is to use SolidWorks as your CAD program and then convert the SolidWorks drawing into an STL file, which can then be imported into LabVIEW as a 3D picture control. I can't think of any other way to achieve this.
These examples might help you:
LabVIEW Interface VIs for SolidWorks
STL Geometry in 3D Picture Control
The Pitch Perfect Tuner
Develop Motion Applications with RIO and SolidWorks
NI SoftMotion for SolidWorks
Connect NI LabVIEW and DS SolidWorks
I hope that helps.

How do I detect MXI2 card programatically with VB or VC++

How do I detect MXI2 card programatically in VB or VC.

Sunil,
A National Instruments PCI-MXI-2 and/or VXI-MXI-2 can be detected programatically a number of ways. The most fundamental and portable, and best code practice, is to use VISA functions detect and identify all VXI modules, including the controller (in this case, MXI-2). A "VISA Find Resources" function will provide a list of all controllers and instruments on the system. All VXI devices will be found with a VISA resource of the form "VXIx::LA::INSTR", where "x" is the system number (typically 0) and LA is the device's logical address. After you retrieve the list of all VXI devices with a "VISA Find Resources", you can then use "viGetAttributes" to read manufacturer and model from the instruments for specific identification.
This method uses the VXI and
VISA standards, so it will work not only with MXI-2, but any other controller you choose to use in the future, even if it is a non-National Instruments controller. This portability is one of the major advantages to using VISA.
You can download VISA from the ni.com web page at the following link:
http://digital.ni.com/softlib.nsf/display?ReadForm&lookup=NI-VISA&view=current&node=132060_US
When you install VISA, you will have a an examples directory (for example, c:\vxipnp\Win95\NIVisa\Examples). In this Examples directory are examples for C, VB4, and VB5. One of the "General" examples is a VISA Find Resources Example. You could easily modify this example to detect manufacturer and model of the found devices.

How do you use Synergy 7.1 with LabVIEW?

My company has reciently installed and configured IBM Rational Synergy 7.1 to be used as our Source Code Control tool. I have installed the appropriate Microsoft Source Code Control Interface so that Synergy will show up in LabVIEW and it does show up in the "Source Control" options window.
However when I select Synergy as my source control tool it does the following:
1. Brings up the login window - I am able to login with no problem
2. Brings up a dialog allowing me to select the project to work on, and after I select the project I get two errors...
one from Synergy: "The workspace/project you want to add to IBM Rational Synergy is not under the work area path 'C:\xxx"
(where xxx is my work area for the Synergy project I selected)
then one from LabVIEW: "Error -2941 occured at prefPage_Source Control.vi An error occured trying to get the source control project path. Possible reasons: LabVIEW: The source control provider does not support the specified operation."
I first tried this on an earlier version of Synergy that matched what is being used in:
http://digital.ni.com/public.nsf/allkb/16D37CCC8659123F8625720500087DB4
But I was getting pretty much the same errors back then too. It seems like it should work in LabVIEW, I just have no idea what I am doing wrong!
Anyone out there successfully using LabVIEW with Synergy????
Thanks,
Trevor.

In theory if a source control provider supports the Microsoft SCC interface, it *should* work with LabVIEW. In practice, each provider has custom implementation that sometimes causes problems when trying to configure the provider from LabVIEW. One sticking point for many providers is the expectation or assumption that an IDE will use some concept of a "project" and therefore pass data associated with that project to the provider. LabVIEW does not enforce that concept but does pass valid information.
Synergy was tested back when it was a Telelogic product. It was difficult to configure and required exact steps to get it to work correctly. The linked knowledge base were steps taken that worked for a few customer setups. It's possible that on other Synergy setups the exact steps may not work. Also, you might check to make sure you try to configure existing Synergy projects and not try to create new ones from LabVIEW.
The error you mentioned seems to imply that some data is not supported by Synergy. I am not sure if Synergy would be able to track down the issue, but I would recommend contacting them to see if they can pinpoint what data LabVIEW is sending is not valid.

How can I create a zip file with LabVIEW?

I would like to compress my data (ASCII format) to an archive.
I use LVZlib.vi to compress and decompress data but I would like to be able to read the output file with a software archiver such as PowerArchiver/WinZIP.
Someone knows how I can create a file compatible with zip or gz standard format, thanks !

>> Yes but I have to install a special archiver (with ms-dos ommand line ability
>> such as pkzip,arc,rar,arj...) on the computer where I install my LV application.
Search for "gnu tools for windows" and get zip.exe, gzip.exe, bzip2.exe and others (even the source, if you like). These are about 50kB files that run in place (no installation) - easy to include in a distributed app. Oh, since I'm logged in I'll attach a couple, though I don't have the source on this machine).

Is the Intel I340-T4 Ethernet card compatible with LabView 8.6?

We are currently looking in to having our LabView program process the output of two Allied Vision cameras, run through a PCI GigE card.
On our old machine (32-bit Vista), we have a PRO/1000 PT Quad working just fine with the LabView interface - and we want to upgrade to a better PC with 64-bit Win 7.
We are under the impression that PRO/1000 PT is not compatible with Win 7, and were looking into either I340 quad-port adapters:
http://ark.intel.com/products/49186/Intel-Ethernet-Server-Adapter-I340-T4
Does anyone have any insight as to the compatibilities of the Intel 82580 controllers with LabView 8.6?

Hi Civa,
Scott here from AVT technical support. You are correct re. that PT card not being Win7 compatible. Here's a link to our current recommendations for NICs and switches.
http://www.alliedvisiontec.com/fileadmin/content/PDF/Support/Application_Notes/Hardware_Selection_fo...
If it's NOT in that list, it doesn't mean it won't work, merely that we haven't tested it and do not know. We do not attempt to test every 3rd party product on the market.
And our testing is typical with AVT SDKs not with Labview, though there are thousands of joint AVT / NI customers, and we'd have heard by now if there were any conflicts, I am confident.
Regards,
Scott

Are there any PCIE CAN Cards Compatible with Labview RT?

Hi,
I am looking for a mini PCIE CAN card or PCIE 1X CAN card that will run under Labview RT. Are any of you using a PCIEC AN card with Labview RT?
Thanks,

Hello Phillip,
I do not believe that we have any PCIe CAN cards. Here is a link to the PCI CAN cards that will work on LabVIEW Real Time(http://sine.ni.com/np/app/main/p/bot/no/ap/icomm/lang/en/pg/1/sn/n24CI,n21:17,n17:icomm,n19:Real%20T...). Please let me know if you have anymore questions. Have a great day!
