Create a custom rule file with an Item.Count LTE parameter value that is
greater than 2000.
If you select None and do not apply rules, clicking [Show Tags] will generate a
list of all points from Logix controllers.
2. Select a Tag file.
The Tag (also called tag attribute) file is an XML file that determines the
properties (attributes) of the points to be created. FTHMETagDefault.xml is the
default. You can view the tag properties files by clicking the icon to the right of
the drop-down menu.
Tag attribute files are managed through the Rule Editor. Use the Rule Editor to
create and edit tag attribute files that you can upload to the module.
3. Set the scan rate.
The scan rate is the rate (in seconds) at which the data will be collected.
If you use multiple tag attribute files that contain a variety of scan rates, you must
select default from the drop-down menu to retain the rates configured in the tag
attribute files.
See “FactoryTalk Historian ME Rule Editor” appendix for more information about
using the Rule Editor.
See “Uploading Files to the Module” for more information on uploading tag attribute
files to the module.
