11.2.6.4 Viewing @aGlance/IT Current Tagnames
If the number of current tagnames which have been configured exceeds the number which can be dis-
played in the @aGlance Current Tagnames window, click Next to view the next portion of the Current Tag-
names list. Click Prev to move to a preceding portion of the list.
11.2.6.5 Configure @aGlance/IT History Tagnames
The @aGlance/IT interface can be configured to access data in the historical, archival, historical block and
archival block databases. Click History Tagnames to open the @aGlance History Tagnames window
(
Figure 11-5 ).
Configuration of @aGlance history tagnames is accomplished in the same manner as configuration of
@aGlance/IT current tagnames. Follow the procedures described for using tagnames configured in the
historical, archival, historical block and archival block databases.
File name syntax plays a role in determining which database will be accessed for data. Each historical
database tagname must be unique on the Micro-PWC network and represent a Micro-PWC server tag-
name.atom combination. To make a permanent record of the data, it can be archived to tape. Archived
data can be restored for later viewing and use.
The restored data is known as the archival database. Data from the historical and archival databases is
requested in the format:
<
tagname>.<atom>
A historical block is a single entity which contains data collected from multiple points in a Micro-PWC
server. All the tagnames configured for collection by a historical block share the same collection parame-
ters (i.e., collection rate). Like historical data, historical block data can be archived to tape to create a per-
manent record. This archived data can be restored later for viewing and use. The restored data is the
archival block data. Data from the historical and archival databases is requested in the format:
< blockname>..<tagname>.<atom>

✎ Note If no attribute name is entered when performing configuration using
a tagname from the historical database, archival database,
historical block database or archival block database then the
attribute name will default to HST. If the attribute name ARC is
specified only the archival database or archival block database will
be accessed.
