Logging and Reporting Tags
Data logging tags are used to record the values of input and output tags to disk so that they can then be used in the Historical Data Viewer and reports. Reporting tags are used to specify groups of tags upon which to generate timely reports. Notebook tags enable users to add notes on the new Historical Data Viewer page.
The relationship between Historian tags and Logger tags is that Logger tags define when data is to be stored, while Historian tags define where the data is to be stored. Each tag for which data is to be stored must have a unique Logger tag. A single Historian tag is often enough for an application.
