„
Monitors alarms and events from third-party controllers. Tag-based alarm
monitoring also makes it possible to monitor alarm conditions from third-party
controllers, which communicate through OPC Data Servers.
„
Provides accurate time stamps on alarm conditions that are generated from
Logix5000 controllers using device-based alarm monitoring. When you use
device-based alarm monitoring, timestamps are applied immediately in the
controller and are not delayed until alarms reach an HMI server. To make sure that
the timestamps on device-based alarms are accurate, synchronize the clocks of all
controllers that produce alarms. The event time is propagated throughout the
FactoryTalk Alarms and Events system, so inaccurate timestamps can affect
where alarms are displayed in the Alarm and Event Summary or the Alarm and
Event Banner as well as reports about the alarm and event history. For more
information about synchronizing controller clocks, see Appendix G, “Time
synchronization”.)
„
Sends process data with events and messages. You can associate up to four
tags with each alarm to include process data with event information and alarm
messages.
„
Secures access to alarm and event operations through integration with
FactoryTalk Security.
„
Generates messages for logging , including audit messages that track operator
actions, system-related diagnostic messages, and historical alarm and event
messages.
„
Displays alarm messages and status information at run time, from FactoryTalk
View graphic displays.
Choosing between HMI Tag Alarm Monitoring and FactoryTalk
Alarms and Events
HMI tag alarm monitoring and FactoryTalk Alarms and Events are two separate alarm
monitoring systems and do not share alarm information with each other. FactoryTalk
tag-based and device-based alarm information can only be displayed in the
FactoryTalk alarm and event objects. FactoryTalk View HMI tag alarm information
cannot be displayed in FactoryTalk alarm and event objects.
If you are already using HMI tag alarm monitoring in existing applications, or you if
you require server redundancy, you can continue using it. However, to take advantage
of the new features of FactoryTalk Alarms and Events you will need to migrate your
existing alarm monitoring system to FactoryTalk Alarms and Events.
