Historical Database 221
5.0 Historical Database
5.1 Introduction
Any Micro-PWC server or client in a group can be configured to collect information from a Micro-PWC
server and store it for use by various applications such as logging, trending and data archiving. This col-
lected data is stored in the historical database.
Historical database configuration is used to create and edit historical database tagnames. Each historical
database tagname is assigned to a point in a Micro-PWC server real-time tag database. Parameters such
as collection rate, storage rate and retention span time are also defined via historical database configura-
tion. Up to 2,000 historical database points can be collected per server node in a console group.
Access historical database configuration using Menu > Configure > Historical Database. The Historical
Database Configuration window (
Figure 5-1 ) will be displayed.
The top area of this window contains a scrollable list of all the points which have been configured in the
historical database. Below this list are buttons which are used to add, locate, edit and delete points in the
historical database.
