Key FactoryTalk Alarms and Events concepts
This section presents some of the common terms and concepts used to describe
FactoryTalk Alarms and Events services, components, and data.
Alarms and events
A FactoryTalk Alarms and Events system produces two types of events:
 Condition-related events are associated with changes in an alarm’s state. For
example, a condition-related event is generated when an alarm changes to In Alarm,
Acknowledged, Return to Normal or Disabled.
Also known as alarms, alarm conditions, or alarm activity, condition-related events
are recorded in FactoryTalk alarm and event displays and logs.
 Tracking-related events are associated with monitoring or auditing changes to the
FactoryTalk system. For example, a tracking-related event is generated when an
operator acknowledges an alarm.
Tracking-related events associated with alarm activity are recorded in FactoryTalk
alarm and event logs only.
For details about these types of events, see the FactoryTalk Alarms and Events Help.
Alarm servers
FactoryTalk Alarms and Events services make alarm information available to subscribing
FactoryTalk View SE Clients through two types of alarm servers:
 Rockwell Automation Device Servers (RSLinx Enterprise) provide access to
alarms detected in Logix5000 controllers that support built-in alarm detection.
 Tag Alarm and Event Servers provide access to alarms set up for tags in:
 Older devices (PLC-5 or SLC 500) that don’t support built-in alarm detection.
 Third-party devices communicating through OPC data servers.
 An HMI server’s tag database (HMI tags).
You can also set up tag-based alarms for Logix5000 controllers that do support device-based
alarms, if you prefer not to set up built-in alarm detection.
