No but there are workarounds.
You can go online with one instance of RSLogix, and drag and drop the data files into another instance of RSLogix in order to get a snapshot of the data. You will have to do this for entire files in order for it to work.
Then download the new file. This won't capture changes that might occur to the data between the time you copy it and the time you download so it is not perfect, but better than nothing.
Another workaround would be to set up a DDE topic and use an external application like Microsoft Excel to capture the data before the download, perform the download, and then use Excel to send the captured data to the SLC.
This workaround requires more trouble to set up, but has the advantage of being more flexible allowing you to pick and choose specific elements within any file(s) to capture. It can also be much faster, depending on the locations of these captured elements and your VBA coding skills.
