Factory Talk View ME Downgrade

There is no easy way to downgrade the entire project; however, there is a very easy way to "downgrade" your graphics. You will have to create an identical program in the previous version, and you should be able to manually import / add component for all of your tags, parameter file, etc.

As for the screens, the trick will be to export your original screens as .xml files using the import/export wizard. You will then need to open the files using Notepad. You will have to change the first two lines of the file which reference the ME Version. The easiest way to change is to export a black display from the previous version and copy the first two lines from that file to the new screens. After you make the change, simply import the screens into the older revision.

Note: You may need to remove small sections of code if you happen to find any new components that don't exist in the previous version.

Maybe you are referring to downgrading the runtime file?

I think for 3.0 and up there is a selection box when you create your runtime and you can select an older runtime format.

Is that what you are looking for?

Darren is correct - when creating the runtime file, you can select an older version of the firmware. Its in a drop down box below the location where you type in the file name.
