Legend.

base. This tagname can be up to 37 characters in length, and cannot contain spaces. The historical data-
base tagname must also be unique on the network.
If no entry is made in the Tagname entry box, the historical database tagname will default to the tag.atom

Micro-PWC tagname. If data is to be gathered from several different
atoms belonging to the same Micro-PWC tag, a separate historical
database tagname must be configured for each one.
