opening a labview 8.5 file with labview 8.21
Hello,I was working on a project at home with labview 8.21, I nearly finished this project but I addes some stuff at school where they have labview 8.5.Today I wanted to open the labview file on my computer, but It gave an error:
labview load error 9: Vi version 8.5 is newer then labVIEW version 8.2.1.Is there any way I can open the file on my computer?Or can I save the file at school als a 8.2.1 file?
thnx in advance,Seppe
Hi Seppe, just save it in school using "Save to previous" from the file menu...
You'll have to reopen the file on a computer with LV 8.5. From there you can do a Save as Previous Version to save back to LV 8.2.1
Hi Seppe, if you have LabView 8.5 you can save your vi for previous verions (8.2.1 and 8.0)Mike
ok, thnx for all the correct answers !
...Can LabView 8.5 read LabView 8.5.1 VIs
Since LabVIEW 8.5.1 is only a bug fix, can LabVIEW 8.5 read any VIs generated in LabVIEW 8.5.1?
Simple answer YES. But it will the VIs compile so it is a good idea to make a mass compile in the folder where the VIs are.

LabVIEW has been cross platform since version 3 (partially in version

Costello, you can update the VIs within the LLB to LV 8.5 if they do not have their blockdiagram removed.....hope this helps,Norbert
How can I update ? When I start the .vi in the lbb he dont found somme .vi located in DAQmx (wrtie.lbb, start task.lbb,...) How can i install this lbb?
Costello, if you get loading errors when opening one VI from the LLB like you the ones you get, you have missing components.Since you spoke of DAQmx, i asume that you didn't install NI DAQmx on your machine. You should catch that up.hope this helps,Norbert
...I need convert LabVIEW 4.0 files to LabVIEW 8.5. Can it be done?
I am running LV8.5. I am upgrading and/or converting an old legacy system. All I have is the disk with the VIs from the old system. I do not have an older version of LV installed.
I can install all the way back to version 5.1. But I am concerned, can LV8.5 convert 5.1? The real question is what is the earliest version of LV that 8.5 will convert and will that version convert 4.0.1?
I have to imagine this has been done. With all the legacy systems going obsolete. This should be a common need.
Thanks for all of the responses. I have about 500+ VIs to convert. I would not be able to post them because of the nature of the projet but thanks for the suggestion. I have to imagine that someone in the office has 8.2 still floating around. I do not want to go back to 6 or 7. I will hunt for an older machine in the AM. Maybe a good job for an intern.
...Installation of LabView 8 after LabView 6
Good afternoon everybody,
I've got a big problem with LabView. The fact is that I begin with this software...
I've just installed LabView 8 on a computer where LabView 6 was installed. Once the installation finished, I tried to launch a VI That was developped under the old version.
The problem is that two VI can't be found :
- AI Sample Channel.vi
- AI Acquire Waveform.vi
Therefore, I can't use anymore the program that was working before... What is the solution to get everything ok please ?
Thank you very much !
the VI will now be opened in LV 8 instead of LV 6. So you need all the
components which have been used during developement in 6 in 8 as well.
The VIs you are missing are from the DAQ-driver. Since the DAQ-driver
has been rewritten in the times of LV 7, the new driver is called
DAQmx. This one is not available for LV 6, but is the driver which is
currently installed with LV (if you installed it with the drivers at
all...). The "old" driver has been changed a little and named
"traditional DAQ" nowadays. You should find the missing VIs in the API
from the trad. DAQ. So i asume that everything you have to do is:
install trad. DAQ.

Need to open my LV 8 VI in LV7, due to different plattforms...
How do I make it possible?
You will have to save out your VI using LabVIEW 8 first, select the Save with options. Then you can select the previous version, which probably is 7.1. ( You will have to repeat the procedure using LV7.1)
If you have used any of the new functions and featured in your VI(s), then these will be lost when you save backwards.
Hope this helps
1) I was just trying your advice on my system and I don't see 'Save with Option' . There is Save, and Save As..
2) I have a llb file and I wish to know which version it is...how can I find out? (I'm using 8.01). I suspect it is 7.1 and I get bunch of errors when it opens.
3) If the vi is 7.1, will LabView automatically convert it to 8.0?
p.s. I'm mainly a CVI developer, and apologize for the "basic" questions...
Thats the trouble when you dont have labview in front of you. Looking at the manual chapter 7-7, there should, be under menu item File a 'Save For Previous Version'.
I think under the VI Properties, under the change history, you should be able to find out what version it is. LabVIEW will try to convert automatically, but there are some issue that it cannot cope with. The release notes should identify these.

Can labview take an existing wav file (previously recorded) and perform an FFT on this file?
Is there any way to do this?Thanks
Sorry wave analysis is not my strong side, but you should be able to pass the wave data to the express vi for spectral measurment and play around with the different analysis modes like power spectrum or peak FFT values, what is the wave file from? what are you trying to analyze? You might consider posting a new topic on analysis and see what advice people come up with.
...upgrading cRIO from Labview 7 to Labview 8
Hi again :)
I have a cRIO system that is running Labview 7. It runs fine. No problems. We've upgraded to LV8 and I'm wondering if I should convert the LV7 system to LV8. The only reason I would do this is because for me LV8 is much easier to work with regarding cRIO (using DMA, setting up the project etc.).
Now, if I attempt to upgrade the LV7 cRIO system, what kinds of problems will I run in to? I assume it means formatting the cRIO, installing LV8, converting the program from LV7 to LV8...
Is there an FAQ regarding this, specifically about the cRIO?
I think our latest CD is LV8.01 or something like this. Since we have the subscription, I usually wait until I receive the CDs.

i am on my labview working with 8.5but at work, we only have labview 7.0.what would be my best way to get my vi to be 7.0?thank you so muchMessage Edited by krispiekream on 06-19-2008 03:59 PM
In order to go from LV 8.5 to LV 7, you will need to have LV 8.5 (save it back to 8.0), LV 8.0 (save it back to 7.1) and LV 7.1 (to save back to 7.0).
If it's only a few small VI's, you can post them on the forum and ask someone to do the saves for you. (Best if you do the save back to 8.0 and post that in order to eliminate 1 of the 3 steps for whoever will do the rest of the conversions for you.)
yeah. great.. i did all those steps.i went from 8.0 to 7.1i dont have labview 7.1 so i can't go to 7.0.can someone please help me.
Please try the attached to see if it works with LV7.0
Hopefully it does!!
thank you so much. i'll try it right now.

Hello I need some help with regard to calling a LabVIEW-built DLL in
LabVIEW.I have created a vi in LabVIEW. I made the DLL for this vi. I
called this VI as a re-entrant in another vi.This vi(calling DLL) has
been working fine till yesterday. Since yesterday, it started crashing
LV.I need some help in this regard.I am attaching the
screenshots of the Application Builder configuration window, the B.D of the vi
using DLL and that of the configuration window which pops up when i call the
DLL.I made a vi which performs FRA. I built its DLL.I have around 10
inputs. I output 3 one-dimensional arrays, and a string from the DLL.When i
build the DLL, the builder defines the outputs 'gain', 'phase' and 'frequency'
as arrays of 8-byte double.When i call this DLL in my vi, the configuration
window sets them as 'numeric' outputs.Why does this happen? What is the
solution to this?When i try to set them as 'array' in this configuration
window, i get a warning that i am trying to change the data types which do not
match with the data type found in the DLL. Is this the problem with my
code or with the Application Builder?Now, after i change the 3 output
datatypes to Arrays, and set their minimum length(i assumed that this value
means the size of the array ), the vi runs and crashes LV. I am nto sure when it
crashes, why it crashes. It runs fine at one time. It crashes at another time. I

...why labview 8.51 change the variable name programatically and is there a better practice to create a driver for a modbus application using the DSC embeded driver in labview
let me give you a few backgound,
im a developer (labview dsc) i work in the industry and im working in a project we choose labview because it works very ok with other application so we picked up for this one,
the problem is that this application is this big:
150 variables per device
the variables include boolean, strings, double and some re-created variables,
most of this must be historized, so
the trouble i have is this one:
when i create a new device, i use a library per device i used to copy the variables and create a new modbus driver for the device, inside the library, im using modbus tcp, so
to do this faster i copy the variables and then in the variable editor i link it to the right library name, so this sound very good,
obviously this sounds very easy, but well theres a think that i cannot escape, i always have to update the .vi with the new tags and it take a long time,
but well thats my work,
well my problem begins when i return to my application with 4 devices and realize that it changes de variable path to another library i men it gave me the data of other device and not the right one, so thast the first one,
and well in a stand alone app this could not be good,
the second trouble i ve recently,
ive add the 5, 6 devices,
the variable went down
giving me bad values,
i test it with kepware opc and it gave me the right values so its a labview problem,
my question is:
is there a reazon for this,
what am i doing wrong?

I would be extremely grateful for your assistance in helping me understand the timing in LabVIEW.
Here are the details of the system. The data acquisition is done using a simple LabVIEW 8.2 based program consisting of a DAQ Assistant VI and a Write to Measurement File VI, which writes data in TDM format (binary with XML header).
The hardware consists of a 1042Q chassis that contains 2 PXI-6133 cards. 16 transducers are connected to these 8 channel cards. The chassis is connected to a PC by means of MXI-4 fiber optic cable and a PCI-8336 card.
I would like to sample all 16 channels simultaneously at 500 kS/s for 2 secs. or 1MS/s for 0.5 secs.

Several attendees requested LabVIEW 8.5 data for the benchmarks I showed at my NI Week presentation - TS1284 - Reference Objects in LabVIEW. In addition, the severe performance degradation seen in Datasockets going from LabVIEW 7.1 to 8.2 was an artifact of my testing environment. I have fixed it and now actually see a performance improvement. I have updated the presentation and zipped it and the test code in the attachment below.

Dear NI tech support
I have found an error in the Read LabVIEW Measurement File. As I try to read a normal data file created by the Write LabVIEW Measurement File, I received the error 100. As I investigated the issue, the problem is in the ex_GetHeaderFromChunk.vi. Sometimes, for an empty input chunk, it is unable to cut the header correctly, and the next data reading would then return an error. The problem was found in 3 out of 15 data files (all very large).
I have managed to find a temporary solution by changing the chunk size from 65000 to a much higher number (+1...N).
Upon your request, I am uploading an example onto the ftp site. The file name is dataX7.zip.
It includes the data file (the smallest of the ones that did not work), the LV program to run, and a text file with some old comments.
The largest data file I have is 1.6GB. It took me several hours to find the chunk size that would allow me to process the file successfully.
LV is v7.1.
What version of LabView did you use to receive no errors? I used 7.1. This error might have already been corrected in the current release. Please let me know in which version was this error corrected.
I did run the VI in the same directory, as well as from another directory. This makes no difference.
The error happened in LVM segment #28. Could you please let me know what other information you require.
