Download from Crio to Labview

[MachineSMMC]

Is it possible to download from Crio to Labview. I want to be able to pull the code off of the Robot and put it back on the PC to make sure we are editing the correct program. (we lost all of our programmers last year)

Thanks

The file on the cRIO is an executable program generated from the LabVIEW project. You can retrieve it from the cRIO if you want (using ftp), but you won't be able to do anything with it. It is not in a form that can be edited, and there aren't any tools to turn the executable back into the VIs that were used to create it.

Think of the VIs you edit as the equivalent of eggs and flour and sugar, and the .exe file on the cRIO as a baked cake. If you don't have the ingredients, you can't really use one cake as the raw material to make another one.

Alan, please correct me if I am wrong but would it be possible to pull that executable off and compare it to an executable produced by code they do have?(I am assuming they are trying to find which version of code they last used and have all their code) Similar to when you compare the checksums of files to make sure they downloaded properly?

Assuming they haven't made any configuration changes to their development system in the meantime, that seems like a very good suggestion.

Basically, bake another cake and see if it looks and tastes the same as the one you already have. If they match, you know you have the right recipe.
