Events
An event is a significant change in the status of an element of the system such as a point or
piece of hardware. Examples of events are the occurrence of an alarm, an alarm returning to
normal, an operator signing on, and a batch process starting.
Event details, which include the source of the event, the condition and a timestamp, can be
viewed on displays and included in reports.
Events are initially collected in a system database, and are periodically copied to a Microsoft
SQL Server online event database for queries and reporting. The events are kept in database
for a specified period, after which they are deleted.
Event storage and archiving
If you want to retain events for more than a few weeks, you need to use Event Archiving to
configure:
n
How long events are kept online
n
How often events are archived
Event Archiving allows you set up automatic archiving, or to configure an alarm which alerts
the operator to archive events at appropriate intervals. Event Archiving enables you to archive
events to a network file server or to tape. Archiving to tape uses the Windows Backup
program. Events archived to a network file server can be copied to other media such as CD,
or included in a system backup.
For more information about Event Archiving, see the “Configuring Event Archiving” section
of the Station Configuration Guide.
