Defining Rule Files
By default, FactoryTalk Historian ME provides a rule file named ADDefault.xml, but
you can create your own rule file. The rule file you create is stored on the client
computer and must be uploaded to the module before you can use it for discovering
tags. Rule files are used to discover data points that exist within the controller by
using the rules you create.
The Tag Attribute files are created in the Tag Attribute File dialog box. They are used
to assign specific attributes to the points that are discovered. If you choose not to
create a Tag Attribute file, FactoryTalk Historian ME will use a default Tag Attribute
file named FTHMETagDefault.xml.
By default, rule files are stored in the C:\\Program Files\Rockwell
Software\FactoryTalk Historian M\Rule Editor directory.
