When the Alarm Summary feature is enabled, alarm summary data is stored in alarm summary files which are completely separate to Event Journal, Configuration Change and Historic Data files. They include detailed information about alarms that have occurred on your system.
To enable or disable the Alarm Summary feature:
- Access the ClearSCADA Server Configuration Tool, (see Accessing the ClearSCADA Server Configuration Tool).
- Expand the Historic Configuration branch.
- Select the Alarm Summary entry.
- Either:
- Select the Enabled check box in the Alarm Summary section to allow ClearSCADA to record alarm summary data in the historic database.
Or:
- Clear the Enabled check box in the Alarm Summary section if your system is not required to record alarm summary data.
- Apply the changes to the server.
If you have enabled the Alarm Summary feature, you can view alarm summary data by selecting the Display Alarm Summarypick action for a database object Group (see Display an Alarm Summary for an Item or Group in the ClearSCADA Guide to Alarms).
You can also view alarm summary data in a Queries List or via QueryPad (by editing the SQL of a List so that the list gets its data from the CDBAlarmSummary table). Alternatively, you could create a Mimic that uses expressions to get data from those tables.
