compression deviation specification for them.

default, tag attribute files are stored in the same location as the rule file. Tag
attribute file names have a TCFG prefix. The tag attribute file is displayed in the

files.
After you create the Tag Attribute file, go to the FactoryTalk Historian ME web
interface. Select Advanced in the top navigation, then click Upload Management,
and upload the file to FactoryTalk Historian ME. You must have administrator
privileges to upload files. Ensure that you select the proper file type for the uploaded
file. Select DiscoveryRuleFile from the drop-down menu for rule files, and select
TagAttributeFile for tag attribute files.
