That's fine, but there's just one other thing I forgot to make clear for anyone reading...
Besides which comms they use and RSLinx licensing requirements, the main difference between the Tag Upload Download Tool and the Data Preserve Download Tool is that you can use the former while the controller is in Run Mode (OPC), but the latter must take the controller out of Run Mode before uploading or downloading the tag values. If doing so is not an issue, work away with the Data Preserve Download Tool.

...I can not get the tag data preserve tool to work. I get a cannot connect to controller fault...
I know you can go online to the controller, etc., but is the correct comms path to the controller saved in the offline project? If it's not, you will get the error:
"
Invalid communications path or controller not responding."
Saving a project while online does not save the current comms path to the offline project. You have to set it in the offline project and then save it.
To check if you have any path set, or the correct path set, go to
Communications > Select Recent Path...
See if the
Set Project Path button is grayed out. If so, you have a path currently saved to the offline project, but is it correct for the path you are currently using?
If it's not grayed out, then you currently have no path saved to the offline project. The recent path you have been using should be in the list. Highlight it and the
Set Project Path button should be active. Press it and then save the offline project.
If for some strange reason there is no path in the recent list, then use Communications >
Who Active to browse to the controller and set the path, saving again of course.
You probably know where all that Comms path stuff is. The detail is more for anyone else who might stumble on this thread...
I hope that is all that is wrong.
