Setting up alarm and event history logging
FactoryTalk Alarms and Events generates messages to record the alarm activity that
occurs at tag-based and device-based alarm servers in an application.
The Alarm and Event Historian software, which is installed with FactoryTalk Alarms and
Events, logs alarm information to the databases set up to store logged data. It also
manages connections and data buffering between alarm servers and their databases.
Following are the tasks involved in setting up FactoryTalk alarm logging:
 Install Microsoft SQL Server and supporting components, on computers that will host
alarm and event log databases. For details, see the FactoryTalk Alarms and Events
Help.
 Create database definitions at the FactoryTalk Directory. For more information,
“Defining an alarm and event log database,” next.
 Set up support for alarm and event history logging, for each alarm server in an
application. For more information, see page 12-32.
 Set up alarm and event log viewers to display logged data at run time. For more
information, see “Viewing alarm and event history logs” on page 12-49.
Defining an alarm and event log database
The FactoryTalk Alarm and Event Historian routes FactoryTalk alarm-related data from
alarm servers to Microsoft SQL Server databases. Information is logged when:
 A tag goes into alarm or returns to normal.
 An alarm is acknowledged.
 An alarm is suppressed or unsuppressed.
 An alarm is enabled or disabled.
 An alarm fault is generated or cleared.
 An alarm is reset.
 An alarm is shelved or unshelved.
Database definitions are stored in the FactoryTalk Directory, and can be shared by
multiple alarm servers in an application.
FactoryTalk Alarms and Events also generates audit and diagnostic messages. For information
about logging and viewing these messages, see the FactoryTalk Alarms and Events Help.
