Can I convert a Labview 7.x vi to a 6.x vi?

[awomack]

I have created a vi in Labview 7.1 that I need to use on a machine with Labview 6.1. Labview 6.1 will not open the file. Is there an easy remedy to the problem (i.e. a conversion utility), or am I doomed to either upgrade or re-creation?

You can always save as one version below your current version using:
File >> Save with Options, then select [Save for previous].

However, this will only take you from 7.1 to 7.0.
I believe 7.0 can save files for version 6.1, so if you can get your hands on a 7.0 version, you should be able to get it down to 6.1. Unless you use Express VI's off course because they were not introduced before 7.0 and will not work in 6.x

Good Luck,

Unfortunately there isn't an easy way to do this, unless you have LabVIEW 7.0. LabVIEW 7.1 will save to the previous version (7.0) but not further back. 7.0 should be able to save to 6.1. Keep in mind that there were many features added between these versions and if the 7.1 program uses them it they won't convert. There were some other changes made as well that aren't as apparent. If the program isn't too large rewritting it in the earlier version may be the best, if not only solution.

Good Luck

Each version can save one version backwards (7.1 to 7.0, 7.0 to 6.1), so you need 7.0 as well. If you don't have it, you can post your VI here (assuming it's not too big).
Keep in mind that new functionalities in 7.1 won't work in 6.1.

I have posted a vi that i have converted from 7.1 to 7.0.
Could someone with 7.0 please convert it to 6.1 and post it?
Thanks

I have posted another file converted from 7.1 to 7.0.
Could someone with 7.0 please convert it to 6.1 and post it?
Thanks

Here you go. 🙂

(NOTE: There are some errors because express VIs did not exist in 6.1. They cannot be converted down)

Actually, the missing express VIs was just a delay in seconds. I have substituted a wait(ms) with the old input mutiplied by 1000.

I indicated the diagram location of the modification with red arrows (two modifications in each VI).

You still need to test if there are any other issues, but now they are at least without error.

Just a side not here.

Some Express VIs can actually be saved back to 6.1 or earlier.

To try it, right click on the express block and select “Open Front Panel”. You’ll get the warning about not being able to go back to the Express VI. Hit OK and the actual front panel of the subVI that the Express VI built will open. You can now save this subVI as a regular subVI, and depending on what’s in it, it might convert back.

Most of the Express VIs contain fairly simply code behind them built mostly from the existing subVIs that ship with LabVIEW, once you get rid of the Express configuration dialog.
