Versions of lab view

Hi:
Just a few days ago i put this message:
Hi:
Im trying, to find a way to search, a file stored in different subfolders of a main folder, and copy, i mean i have a VI which makes a folder everyday (the name istoday date, or yesterday date), and inside that folder is a serial1.txt log file, but yesterday (for axample) the same log file (serial1.txt) was generated, how can i search in lab view all of those serial1.txt files?? By putting just in the search field, the main folder name???
And I want to copy each of these serial1.txt, to different paths???
So in this days, i ve working and the file is ready, but this archive just search like this: main directory /2nd directory/ 3rd directory/Files.... I mean if the files is deeper in more subdirectorys, does not work well works for me.
Im working in lab view 8.5 but, when i tried to put the .exe file in the computers where i have to look for my files, sorprise!!! the computers have the version 7 express or somethig like that so i cant use my file. IT Is possible change the version of my file to version 7?????
Solved!

I don't know if you are still asking the same question in this thread or not. If you are, don't start a new thread.
As far as the exe, all you have to do is install the 8.5 run-time engine on the other PCs. If you had created an installer (something you should always do), the run-time would have been included.

Full version of lab view!

Hi ,
does anyone know if it's possible to download a full-version of LABView on
any homepage !
-DS-

DS,
No. Not only is it not available, but there is the whole licensing issue to deal with. Not even the evaluation version of LabVIEW is available online because of the sheer size of it.
If you write to NI, or check their website, they can send you an evaluation copy.
If you are just looking to have something so that your customers can view LabVIEW code and run programs, then check out the LabVIEW Player.
Perhaps if you elaborated on your question, we might better be able to help.

Communication between Lab view and Controller via USB

USB communication between C8051F320 and Lab View. I try doing methods given in the NI site(http://zone.ni.com/devzone/cda/tut/p/id/4478) and atlast, it gives me error −1073807302 so if any one can answer my question please do post me the details concerned to it.

My devices show up as NI-VISA USB but I'm not sure if that makes a difference and I'm not using USB RAW either. One thing that you can run is a VISA Property node like below and see what it reports. Also, what version of VISA are you using? If you are not using 4.0, you can download it from http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C0E91?opendocument&node=1....

I want to get and set windows system time through lab view

Hi
I want to get and set windows system time with the help of lab view 8.5.
please help me out.

Installation of Lab view 8.20, DAQ Assistant has disappeared & Instrument I/O Assistant cant be used

After upgrading to Lab view 8.20 and on a 8.20 new install I
notes’ that
DAQ Assistant has disappeared from the tool pallet completely.
Also that Instrument I/O Assistant cant be used or
configured and produces an error
“NI Measurement & Automation Explorer or the Instrument
I/O Assistant is not correctly installed. Please install these from the Driver
CD”
I have checked both of these and all parts are fully installed
and I cant fined what part of the Full version of Labview would course this
problem.
Would a completely new installation with default settings
clear the problem, what has coursed these tools to be not avalible.

Hi Trevor
You need to load on the Drivers for DAQmx, if you have a CD you can load them on from there otherwise the link to download NIDAQmx 8.3 is:
http://digital.ni.com/softlib.nsf/websearch/7feaee6a4b4aa836862571c00064e6ca
There is a order in which you must load things on for everything to work correctly,
LabVIEW --->> Modules & Toolkits --->> Drivers
This should solve your issue

Application builder for Lab View 8.6.1 , 2009 SP1 and 2010 SP1

All 3 Versions seem to have huge flaws. With 8.6.1 When trying to build and application I get a duplicate name error and the application won't work. With 2009 SP1 I get Error 1003 broken VI when I have no broken VI's. Again Application won't work! With 2010 SP1 After the application is built for some reason lab view can no longer find the Excel sub VI's no matter how I place them in the build. And again application doesn't work. With all 3 versions the Vi's and over all programs work perfectly in the development environment. The application builder seems extremely flawed.
I would currently like assistance with 2009 SP1 problem the Error 1003 broken VI. I have reinstalled and rebooted my machine several times , tried including as much as possible in the build and still get the error about a broken VI. That works perfectly in the development environment. Please HELP?
Thank You

LAB View crashes changing background colour

My LAB View runtime application (7.0) crashes sometimes without error message when changing the background colour of my frontpanel. My operating System is XPP.

We have reproduced the crash with the development environment and with the runtime version (.EXE made with application builder).
Enclosed are 2 word files: one from development crash and one from runtime crash.
The runtime crash is from a computer with visual studion 2003 installed, so I made some visual studio debug snapshots.
At the development crash, there are no internal errors to investigate!

Insytalling lab view 8.5.1 on windows 7

how do install lab view 8.5.1 on windows 7

Did you even bother to do a search? If you had you would have seen that this issue (i.e., installing earlier versions of LabVIEW on Windows 7) has come up, literally, dozens of times and has been answered dozens of times.
Please do a search.

When opening my vi file on lab view 6 it asks for AI read.vi

Ok so I installed version 6 of lab view on to my laptop because apparantly that's what the program i would like to run was written in. After finally downloading all the files and installing them, I get this message where it tries to locate the file AI Read. vi and AI Clear.vi
I have no idea where to get them from
Message Edited by problem finding "AI Read.vi" o on 09-21-2009 04:37 PM

They are part of the Traditional DAQ driver. You need to install that after installing LabVIEW.
By the way, why didn't you come up with a more creative login name rather than just a statement of your current issue? If you ever need to post again to the forums, that login name is going to look rather silly.

Lab View crashing when creating new bound variable

Hi,
I have to connect to an OPC server from Lab view and have played around a bit with the OPC client options.
I would like to use shared variables as that seems like a handy way to access the needed variables. I have followed the instructions in http://zone.ni.com/devzone/cda/tut/p/id/7450 .
However when i use the create bound variables feature LabView crashes when i browse for OPC tags, step3 under "Create Shared Variables that Connect to the OPC Tags through the I/O Server". If i try to expand the node "OPC1" LabView crashes. I try to access the built in NI OPC server locally.
Also during this process LabView gives warning box saying "Configure OPC server to run with an identity of interactive user". we did try the the steps in http://zone.ni.com/reference/en-XX/help/371618G-01/lvdschelp/config_local_opc_serv/ . However the The interactive user button was disabled under NI OPC sever properties.
Is there something i have missed? Something that needs to be configured before going through that tutorial?
I run LabView 2011 on a 64 bit Win7P computer. The DSC module and the NI OPC Servers are installed and seem to work (when running the OPC examples ).
Thanks.

Hello AmritaNikhil,
Thanks for the post, I have a few questions for you about this issue.
What versions of NI OPC Servers are you using?
Is the server hosted on your local machine or on a remote machine?
Are you able to successfully connect NI OPC Servers and NI OPC Quick Client?
Have you been successful in using OPC IO Servers in the past or has this issue occurred since you have started your application?
Can you consistently reproduce this crash?
You can try to work around this issue by using Network Items rather than Project Items when creating bound variables in the Create Bound Variables window. Please try this option and let me know if you have any additional information about your application that may be helpful in solving this issue. In addition, I have also included a link to a similar post. Hope this helps!

Looking for lab view example

My application consists of collecting data from a bank of sensors as pressures and tempratures vary. I would like to run a lab view VI that tests the sensors, varies the environment and keeps track of all results, sorting them into good and bad. Each sensor needs to be tested in different pressures, then the temprature increases and the pressure test begins again. If there is a lab view example that might be able to get me started, I really need to find it. Thanks for any and all help.

There are a number of examples that ship with LabVIEW and their usefulness will depend on information not specified in your questions - such as what version of LabVIEW you have, what type of DAQ card(s) you have, and if you are using any SCXI hardware. If you open LabVIEW and go to Help >> Find Examples, you can search through a number of different examples.
For the application it sounds like a good place to start would be with an Acquire to Spreadsheet type of file that reads, graphs, and logs data. From there, depending on what you mean my using the card to vary the environment, you can find other examples of AO and DIO to perform these type of functions. These examples will give you a good starting place as to how a LabVIEW program works and the general flow
that you will need to follow.
Also, depending on your other needs, you might considering looking into examples with triggering to enable you to control when your program starts.

Getting error messages upon startup after installing Lab View 5.1.1.

I have recently purchased a DAQ system along with a computer, which uses a readout program written in Lab View. however, after installing Lab View 5.1.1 on this same system, I started getting some error messages and the readout program no longer works. Here are the error messages:
"The \SystemRoot\system32\drivers\nidmmk.dll device driver could not locate the entry point ?single PointWrite@mdsSimpleDIGPortPrimitive@@UAEXKKKAAJ@Z in driver Nidaq32K.sys"
as well as
"The ordinal 2011 could not be located in the dynamic link library nidaq32.dll. An error occurred while loading VT Digital buffer write.vi"
I would greatly appreciate any help I can get.

Hello,
Installing LabVIEW should not effect an installation of NI-DAQ. However, it seems to me that we may have installed a different version of NI-DAQ on top of the current version. This is very possible because the old LabVIEW CD�s contain NI-DAQ on them.
In this case, there is not an easy solution, we could try uninstalling and reinstalling combinations, but it will probably save the most time and effort to uninstall all National Instruments products and reinstall them. The best way to do so is from the ADD or REMOVE Programs utility from the Control Panel. Then we want to remove the following registry keys (BE SURE TO BACKUP YOUR REGISTRY!!)
HKEY_CURRENT_USER\Software\National Instruments <-- Delete the entire tree!
HKEY_LOCAL_MACHINE\Software\National Instruments <-- Delete the entire tree!
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ or \ISA and delete registry entries containing any keys with 1093 in them.
Do not worry if any of these trees are not listed. If you have Administrative rights, and you still cannot delete these keys, that is also OK. Continue with the remainder of the process.
Make sure that you do not have any of your own VIs or other files saved in the "C:\VXIpnp", "C:\Program Files\National Instruments", or "C:\WINDOWS\nidaq" folders. If you do, copy them to a different location. If you are concerned about keeping old virtual channels and your SCXI setup intact, then backup the "C:\WINDOWS\niconfig.daq" file, too. Delete all folders and files mentioned above.
Note: If you have Windows NT/2000, replace "C:\Windows" with "C:\WINNT" in the paths listed above.
Once these steps are taken care of, we should have clean system. You probably want to reboot and then reinstall the software. You should install development environments first, and then install drivers.
Just let us know if this does not take care of the problem, or if you have any questions on how to complete a step of the process.
Best regards,

NOTE: Turning off virus scan programs greatly increases the speed of uninstalling and reinstalling.

Installing Lab View 8 Evaluation - My ie6 isnt recognised

Hello guys,
What happens is that when i start installing Lab View 8 Evaluation version it says that
i need ie4 or higher to proceed. I have ie6 installed , though. I already tried to reinstall ie
and also to reinstall labview, but it didnt work.
Any suggestions?
Thank you.
Joao Gabriel

Hello Joao,
LabVIEW uses Internet Explorer for a features such as the help and documentation. It sounds like you have tried reinstalling. Have you also tried to uninstall what you have currently and then reinstall? Have you installed all possible patches for your browser as well? As a last resort, you may also want to try doing a custom install of LabVIEW and deselect the Help and Documentation, just to see if it will install correctly. I hope this gets you started!
Cheers,

How to configure a shell and tube heat exchanger with Lab VIew to get data

HiI
In our undergraduate chemical engineering labboratory we want to configure our shell and tube heat exchanger with a DAq and Lab VIEW to get information about the temperaure (of the cold fluid stream being heated), the pressure (of the steam on the shell side of the heat exchanger) and the flowrate (of the water being heated).
Can anyone suggest thermocouples, pressure transducers and flowmeters to fit between the heat exchanger and the DAq?
P.S. the heat exchanger is already fitted with thermometers, a pressure gauge and a rotameter but we don't know how to connect these hardware to the DAq
Solved!
Go to Solution.

It sounds like you have enough information to pick out appropriate sensors, you just need to do the research. I would start looking through the Omega catalog, or give them a call - they're usually helpful. I can't take the time to spec out parts for you - that would be a lot of time spent on someone else's project. Most pressure sensors put out either a 4-20mA or 0-5V signal, either of which you can read through an analog input on a DAQ; measuring a 4-20mA signal requires a resistor to convert to voltage. Most of the NI DAQ boards can read a thermocouple on an analog input, but make sure that your hardware does support reading thermocouples. For accurate readings, use a device that has built-in cold junction compensation - for example, the SCB-68 connector block - and for the most accurate readings, get a board specifically designed for temperature measurement.
For the flow measurement, a standard, simple solution is an orifice plate. You put a differential pressure transducer across it, look up the appropriate equations, and use them to calculate the flow rate given the density of the fluid (which you'll be able to calculate from the pressure and temperature, since steam tables are widely available). There are other differential pressure devices available as well - at a previous job we used a V-Cone from McCrometer. If you call them they'll spec one for you - but get an approximate cost first to make sure it's within your budget.

How to get lab view to display my plot in DB

hi guys
i desigED n an operational amplifier to determine the gain product band width using a 741 chip and the gain of the circuit is 1000, meaning that the gain bandwidth PRODUCT will occur at a frequency of 100hz. but i have a problem, when i start the frequency sweep from the function generator from 10 hz to 100Khz which IS the final frequency value i have set for the program. when the lab view program stops and i export the data to excel sheet i will be getting the DB axis value in a SMALL VALUES AND IN DIFFERENT UNITES WHEN I PLOT THE GRAPH USING EXCEL, while the frequency is in log10.
pls can any one tell me how to solve this problem to start getting the right cut off frquency on the graph. find aattched my vi and the excel data from the vi that is in a different unit not in DB

thanks Jeff Bohrer for your reply, what i mean is the y-axs of the plot is in DB aleady, but when i export the data to excel i will be seeing the gain in 0.8, 0.7,0.4 which is not normal, which will not give me the -3db point of the gainband width product of the circuit
What you want to do is plot the Log(10) of the frequency on a linear axis!!!!!!! The export - exports the values not the axis scale. exporting a log(10) of the Y axis will export the log of the axis- (of couse, you could change the graph axis scale in Excel too...... but)
