Version Incrementing

The FactoryTalk AssetCentre Archive uses a checksum compare to distinguish between two different files. In order for a newly checked-in file to receive an incremented version number, it must return a different checksum value than the latest file already checked in to the archive.

Due to the way in which the checksum value is calculated, only changes to the file itself will alter the file enough for FactoryTalk AssetCentre to recognize a difference. An example of a file alteration which would not return a different checksum value would be a change to the date/time stamp of the file.
