I have a labview 7 vi and i have labview 6.1
I have a labview 7 vi that get data from excel specified field. I have only labview 6.1 : could someone translate or "save as" these vi in labview 6.1 format ?
Thanks in advance.

I have read in a tutorial for the board 1200 that I can calibrate it with the Calibration and Configuration Palette in LabVIEW, but I do not have them and I could not download it to access its libraries, so I can only download the NI-DAQ software,What's my best choice and if it is to download the palette with its libraries, how can download it with them?I'd appreciate your answers
If you wish to use your 1200 device in LabVIEW, you must download and install NI-DAQ. When you install NI-DAQ, it will ask you if you would like to install support for LabVIEW. By installing this support, you will then have access to the DAQ pallette in LabVIEW. The DAQ pallette requires that you have NI-DAQ installed.
For more information on installing and using your device, you can refer to the DAQ Quick Start Guide. You can download it from:

i am receiving the data through the rs232 in labview and i have to store the data in to the word or text file only if there is a change in the data. I have to scan the data continuasly. how can i do that. I was able to store the data into the text or word file but could not be able to do it. I am gettting the data from rs232 interms of 0 or 1. and i have to print it only if thereis a change in data from 0 to 1. if i use if-loop , each as much time there is 0 or 1 is there that much time the data gets printed. i dont know how to do this program please help me if anybody knows the answer
I have attatched the vi. Here in this it receives the data from rs232 as string and converted into binery. and indicated in led also normally if the data 1 comes then the led's will be off. suppose if 0 comes the corresponding data status is wrtten into the text file. But here the problem is the same data will be printed many number of times. so i have to make it like if there is a transition from 1 to o then only print it once. how to do it. I am doing this from few weeks please reply if you know the answer immediatly
thanking you

I have a problem with simulation in Matlab 6.5 and LabVIEW for PID controllers
I have a problem with simulation in Matlab 6.5 and LabVIEW. I have some methods for granting PID controllers in MATLAB to go but not LabVIEW. International Teams degree to transfer two but when I go past the fourth degree no longer work. We changed the formula for calculating the parameters for grade four and gave me some good values for Matlab award but when I put on LabVIEW have not settled. formulas are available in PDF and are. Please help me and me someone if possible. Thanks
lim.4 generation parameters in MATLAB program and comparison methods are for second-degree transfer function.
Solved!

I am using a Dell Inspiron I8100 Laptop with Windows XP Home and am running LabVIEW 5.1 in Windows 95 compatability [I also did so for the install to get rid of the "wrong os" message]. I am able to use nearly all of the functions, but a few of them did not make the transition to my machine. I cannot use some of the VI's contained in the Mathematics sub-palette, I cannot use some of the demos, and it is really setting me back. Instead of an icon for the Mathematics>>Curve Fit sub-palette I get a ? in an icon-sized box that says Curve Fit for it

labview2.bmp 2731 KBFrom your discussion I have seen that you try to use LV 5.1.
It seems that 5.1.1 will work correct. The difference is that 5.1.1 is compatible with Win 2000 and 5.1 is not. This can by a issue.
Another thing I have seen under Win2000 is the rights a user has. Since you use XP Home there should be no restrictions to the user of the machine. One thing to take into account is do you install and use LV as the same user?

Don't forget to give Kudos to good answers and/or questions -
The major issue here is that the test systems must be documented and validated before being released to the production floor. Given this if a test station has multiple test systems deployed on it that have been developed on various versions of LV, TS, and Switch exec how can I force the test system selected to use the correct versions of TS, LV, and Switch exec.? I understand that the solution would be to recomplie everything and bring them up to the latest version but that would then require re-validation according to the QA department. Any advice would be greatly appreciated.
It would be nice if theTS deployment was more like an LV executable... meaning when a LV executable is launched it always knows what LV runtime engine to use when there are multiple engines installed on a PC.Hi,
Multiply versions of teststand can reside on the same system, but only one version can run at a time. They is a utility that has to be run to set the active version.
The SequenceFiles have a version number, and you will find an error will be generate if you try to Load the sequencefile in the wrong version of TestStand.
The labview VIs will only work providing the correct version of the RTE is also installed on your system, even a labview executabe requires the correct RTE to be installed, either as part of the executable installation or as a seperate installation, before the labview exe will work correctly.
I'm not fimilar with the Switch exec but I would expect that it will also require the correct lower level device drivers to be available for the version you are using.
Therefore, as you are indicating that some of your system are at a older version, its difficult to image how you could achive this, considering if you say you have different versions of the software(s). For a start, you may have the problem that newer code/ sequencefiles using additional functionatily not available in the older versions.
I would think your only solution would be to have different deployments covering the different versions you have, or at least bring all your test systems up to the same version of teststand.

I have a application build in Labview 8.5 which wroks fine with Windows XP , this program uses basic read /write functions of NI Visa to communicate with Hardware . This application doesnt work with Windows 7 32 bit/64 and Vista . What changes i need to do to make it work for the said operating system

You need to make sure the machine have the corresponding NI-VISA installed. Check in the NI software pages for the right version.
Also make sure that the com port's can be selected when you first start the application. Eg. if you refer to VISA "COM1" on the XP machine It might be "COM2" on the Win7 machine.

I can not create an Installer on LabView, After install the Vision Builder Demo and then uninstall it. I can not create a Labview installer anymore, it asks me for a Vision Builder Installer, even if My Labview program does not have nothing to do with it...
Solved!
Go to Solution.Hi Shada this can happen if you are including additional installers to your installer for example DAQmx. When you are doing this the installer has to include other files like MAX (Measuremente and Automation Explorer). Probably when you installed Vision Builder it updated MAX, so when your installer is trying to Include MAX, its asking for the source where it was installed in your computer in this case Vision Builder.
Here you can cache the information so its not asked again, or you can download a newer version fo DAQmx, so it will update MAX and change de dependecy.
You can find more details about this issue in this KB:

I've been involved in design and developing Digital Circuits like interlock units, Position monitoring and display systems etc. Now I want to work upon FPGA based circuits. Can anyone suggest me plz that how to start with?

I have to send UDP multicast and Unicast messages to a remote port from a single source/local port. I tried by opening UDP unicast and multicast in the same port and got the expected error. I tried by opening a unicast connection and sending unicast messages.After that when multicast messages has to send I closed unicast and opened multicast in the same port.This is not throwing any error. But my requirenment is to comminicate with another application in C ++ which recieves this data, throwing an error of lost connectivity and both the applications are not abled to communicate properly.
In the other application with C++ this is implemented using port sharing. So how port sharing can be implemented in labview so that I can send both multicast and unicast messages from the same port?
Thanks in advanceUDP is a sessionless protocol, meaning that anyone listening on the specified port CAN receive the data. CAN because as you noted there is no guarantee in the protocol that it will be received. And if you send the data not to a specific address but a multicast address not only one computer can receive it but in fact every computer on the same subnet listening to that multicast address and depending on the TTL of the packet also computers in neighbouring subnets, although that last one is not a very reliable operation since routers can be configured to drop multicast packages anyhow despite of a different TTL saying otherwise.
Accordingly there is no real way to make sure that a receiving UDP port is not already in use, since you don't build up a connection. UDP is more or less analogous to shouting your messages through a megaphone, and anyone listening on the right frequency (port) can hear it. You do bind the sender socket to a specific port number but that makes little difference.

I have written a binary file with a specific header format in LABVIEW 8.6 and tried to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?
I can think of two possible stumbling blocks:
What are your 8.6 options for "byte order" and "prepend array or string size"?
Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

alled in PCI-bus IBM PC, which does not have GPIB interface. Which way would be easier for developing my own instrument driver: a new GPIB controller + interface or 2915 Kinetic Sys. PCI-bus in-slot interface? Can the latter interface be used with LabView?
Many thanks.
Victor. I have got a 1500 Kinetic Systems CAMAC crate and 3932 controller. I want to use it with LabView installed in PCI-bus IBM PC, which does not have GPIB interface. Which way would be easier for developing my own instrument driver: a new GPIB controller + interface or 2915 Kinetic Sys. PCI-bus in-slot interface? Thanksalled in PCI-bus IBM PC, which does not have GPIB interface. Which way would be easier for developing my own instrument driver: a new GPIB controller + interface or 2915 Kinetic Sys. PCI-bus in-slot interface? Can the latter interface be used with LabView?Victor,
I couldn't find an Instrument Driver for the 3932 crate controler. There is a driver for the 3988: http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/045f8392cc4d1b01862568ab005fbb49?OpenDocument
If you look at the driver it isn't too complex. Well ... actaully there are certain differences when using the 3988 GPIB controller that the driver takes care of that relate to correctly passing commands (FAN).
If the 3922 controller is similar then maybe you can use the 3988 driver and modify it to meet your needs. I'm not familar with the 2915 Kinetic system so I'm not sure what would be easier.
If you have a GPIB board, then you could try using the 3988 driver with your 3922 controller and see if you can modify the driver to get things to work.
I
've only used the 3988 and that was quite three years ago but it might be worth a try.
Best of luck,

I have some question on "Use LabVIEW to Control two DSP and RTDX"
I have some question when writing LabVIEW. I have DSP6711 and DSP6416, I use RTDX to send data to LabVIEW.
I write three programes for LabVIEW, one is RTDX for DSP6711, another is RTDX for DSP6416, and the final is RTDX for two DSPs.
The program of LabVIEW is workable when doing DSP6711 or doing DSP6416. But there is some problem when running DSP6711 and DSP6416 on LabVIEW at the same time.
How to tell the LabVIEW's tool of " RTDX read" to get the datas from different DSPWhat you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.

If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.

I have Labview for HP-UX and a HPIB card. Is there a way to make them work?
I appreciate any pointers.
Jose Chacon
FloridaJose,
There is a KnowledgeBase entry that talks about using NI-VISA 2.5 to communicate with an HPIB board through LabVIEW 6. Unfortunately, this is only possible in Windows. For HP-UX I'm afraid your only option is to use a Call Library Node in your LabVIEW program to make direct calls to the HPIB driver. If you can obtain documentation on the HPIB shared libraries that come with the board, it is viable for you to communicate directly through a Call Library Node.
I hope this suggestion points you in the right direction. Have a good day.
Sincerely,

I have had LabVIEW Basics 1 and 2 what do I do next?
I always recommend the course of action that I took when I learned LabVIEW (in one week).
Go get "LabVIEW for Everyone" and "Power Programming". They are readily available through NI's website, or through a good technical bookstore, or even a college bookstore. From there, just go through the example programs.
I strongly recommend also learning good style. LabVIEW comes with a style guidelines book (which, apparently, only 6 people have ever read...) This will get you started on the road to good practices. LTR is also a good resource.
Good luck.
Oh, also, when you have gotten some experience, I recommend taking Advanced. I took it (three years after I learned LabVIEW) and was very happy with the course. -
When I pushed a button, this pop-up window has to appear. There will be a slide control and a picture from a camera in this window. Is it possible to make appear this windows while main VI Interface continue to run ? How can I do this ? Thank you for your answers.
Cyril.Here you go. This is simple example. Maybe not the best way, I am just
beginner in LV and still not comfortable with data flow that much. I prefer
events, so I would change this to use Event Structures.
When you click on OK button on SliderMain, it opens Slider.vi. Now both
windows are open and you can interact with both. Now if you click on OK
again with Slider.vi open, you run into problems. Only thing I did was
change VI properties of slider.vi, mainly window appearance.
