...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.

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

It is not possible directly. Somebody with access to version 8.5 needs to save it for version 8.2.
Could you attach that particular vi in your post so that somebody can save it for 8.2
Or you can install Labview 8.5 demo. Works for 30 days....

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 !
...LabVIEW 8.0 changed a constant that was wired to a Case structure to a hidden control to maintain compatibility with LabVIEW 7.1 and earlier.
Y am i getting this msg?
This happened because "...LabVIEW does not compile code on the block diagram that does not execute. For example, LabVIEW does not compile any code that exists within the inactive subdiagrams of the Conditional Disable structure. In addition, LabVIEW does not compile code within a Case structure that has a constant wired to it that would not execute the case with the code..."In the other words, if you have case structure, which is wired to T/F constant, then prior to version 8.x both cases will be compiled. From version 8.x the only "executed" case will be compiled. So, LabVIEW replaces constant with control for ensure that both cases will be compiled as before.

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!!

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. I also tested in LabVIEW 8.5 with the following results, which can be compared to the presentation (same experimental setup).10,000 DBL read/write cyclesMode - Time (ms)Global - 7.6Single Process Shared Variable - 12.8Network Shared Variable - 1980Datasocket - 10700Configuration VI - 745Control Reference - 2440GOOP 1.0 - 2000LV2 Global - Semaphore - 294LV2 Global - Action Engine - 13.7Single Element Queue - 41.4Read of 1MByte BufferMode - Time (ms)

I started using SPC toolkit for a project in Labview 8.2.1, had no problem until I upgraded my system to labview 8.5. It said something like: Some subvis are too old to be converted to 8.5.I went to the Labview Developer suite CD album (labview 8.5), and couldn't find the SPC for LabVIEW, only for LabWindows / CVI. Then I went to NI's website and tried to find more about the toolkit, it seems this one had disappeared into thin air, along with the Enterprise connectivity toolkit (or Enterprice toolkit).Does anybody know if NI stopped developing / supporting the SPC toolkit? Or if NI included it into other toolkit or product?Thanks,-Joe
it could be that there are some vi�s from LV5. So i think if you save the vi�s which are to old to use with LV8.5 with 8.2.1 then it should work.
It is included with the DSC module in 8.5.
Got it! Thanks! -Joe
sorry for a silly question, but I tried to locate the LabVIEW DSC Module 8.5 in my Professional development environment and I cannot find it.
Would you please tell me which disk is it on?
It doesn't come with the pro version. As mentioned, it comes with the DSC which is an option for the Developer Suite or you can buy it separately.

Our testing computer right now just has the user run the corresponding .vi file since we have LabVIEW 7.1 installed on the computer.
If I use 8.5 to compile this .vi to an executable, I realize that I must install the run-time support for 8.5. My question is what effect will installing the 8.5 run-time have on the ability to continue to run the other 7.1 VIs with LabVIEW 7.1.
Should I be concerned with losing MAX settings when installing the run-time support for 8.5? I want to be able to run 8.5 executables but also able to open up a 7.1 .vi file in LabVIEW 7.1 and run it that way also.
Thanks for your help! I have 8.5 on my system and the idea is to slowly replace the running of the .vi files with .exe files, I was just curious in case my .exe doesn't work I can still run the tests with .vi in the mean time.
Thanks for your help folks!
...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.
...labview 8.2 to 8.5?
I have an older version of labview (8.2) and wanted to know if i could update it to the current version without having to buy a whole new system.
Are you asking if there are additional costs to upgrading from LV8.2 to LV8.5?
If that is asking, the answer is yes. You can purchase a Standard Service Program (which is typically included for the first year), which means you automatically get upgrades.
The other option is to go to this link: <a href="http://www.ni.com/labview/" target="_blank">http://www.ni.com/labview/</a> and select upgrade. You then enter your serial number and it should tell you how much to upgrade to 8.5 and/or to a more complete version of LabVIEW.
A third alternative is to contact your local NI representative with whom you can discuss your LV sw / upgrade needs.

Good afternoon everybody,
I've got a big problem with LabView. The fact is that I begin with this software...

Thank you very much !

under Labview 8.2.1 (Jubilee Edition), but under Labview 8.5 the VI
seems to be not correct. The "Run"-Arrow is displayed broken, nothing
Funny Effect in Labview 8.5 beside: In a few cases i've seen the
effect, that my VI works just one time, then never again ?
Have i done mistakes while installing anything. Or are there hidden
registry entries ?

I've seen on a colleagues PC a similar effect with .net-based VI: It

Yes, the examples work fine, with one ugly difference:
In LabVIEW 8.5 the code (e.g. "...Moving from Labview 8.0 ->8.5
I was developing in Labview 8.0 and things were going fine. However when I upgraded to Labview 8.5 my solution just began to behave wierdly.
My event parameter from a C# DLL which is an array that were being passed suddenly arrive empty arrays. When I use the Labview 8.0 to recheck,
the event parameter was being passed correctly with data. Thus I copied out the C# dlls and created a small portion of the solution with the event handling in a new project in Labview8.5 and behold that the event now works.
I would like to know is there any steps that I should be doing when migrating from 8.0 -> 8.5 such as changing paths or etc? I certainly do not want
to recreate the entire solution in Labview 8.5
I just thought I'd chime in on this. I believe there may be some sort
of bug around this. I used the import shared library function today in
8.5 to create an interface to a dll. After tweaking the inputs and
output parameters as necessary, I ran a test vi. In 8.5, the dll is
seeing null pointers when I am sending in pointers to fully populated
arrays of singles. I saved to 8.2 and ran again without changes. It
seems to work.
I'm going to see if we can generate an example dll to illustrate the problem.

In older versions of LabVIEW, when you set the non-default input limits for a numeric and an input was coerced to be within the limits, it was coerced when the input was changed from the front panel or when passed to it from a calling VI. Now, the coercion only occurs when changed on the front panel.. In your case, you can probably ignore it. I th...How to upgrade LabView 5.1.1 project to 8.5?

...VISA issues when switching from Labview 5.0 to 8.5
I am using a pressure transducer that I read using RS-232. In Labview 5.0 I used the Read Serial VI and it worked with no issues (I also tested it with the VISA from 5.0 with no problems either). Now I have upgraded to 8.5 and I seem unable to communicate with it anymore. The usual error I get when i try to read is a timeout error.
I ran the Troubleshooting Serial Line Monitor VI and it seems to work (RI blinks when the output lines are off, DCD RI and CTS blink when DTR is on, and RI DSR and CTS blink when RTS is pushed) The Basic Read and Write VI does not work however. Whenever I get bytes at port it always returns 0. I am using a USB-RS232 converter but this problem remains when I tried using an RS232 port on another computer running 8.2.
I recently added the VISA 4.3 drivers but this did not help.
Thanks for any ideas.
There were some changes to the VISA serial communication from LV5 to LV8.x.
Can you post your code (LV8.5) so that we can see how you have implemented it?

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 am getting an error that the new version does not support these old files. I just want to open these files and look at the code for reference. Can anyone suggest a way to open these files.
One way would be for someone to open it in a version that still supported it and is supported by LV8.5.
For instance, if you post the VI(s) (and hopefully not too many of them), I could open and save them as LV7.x. Hopefully nothing gets broken to this stange and the VI could then be opened and saved to LV8.5.
Thanks a lot for your offfer.
I have a .llb file which has a group of files and one vi files. It will be very helpfull ... Thanks in advance.
The llb cannot be converted because the VIs have no block diagrams. Find the original llb with the source code or you will have to rewrite everything from scratch.
