Technical Description
Fig. 3.4.1.-2 An example of an information flow when something worth
alarming happens. Alarms are evaluated and generated in the
process database.

History database

Events are stored in the history database as event history. The history database
consists of the history database files which each contain events of one day. The
history database is the base for event lists made by LIB 500 Base revision 4.0.2. or
newer. Each event in the history database contains most of the process object
attributes and some history database specific attributes.

Report database

The report database stores historical data and calculated values. It also contains
SCIL programs that are executed based on time or events. The report database
contains data objects, command procedures, time channels and event channels.
Report data in the report database needs to be handled mathematically or
statistically. When data is collected from different sources, SCIL algorithms are
used for data analysis and calculations. The data is then stored in the report database.
The reports can be operational reports, alarm and event reports, trends etc.
Figure 3.4.3.-1 shows how data is put in the report database and how it is then
analyzed.
