Consider and plan your alarm strategy.
Decide whether you want to enable Dynamic Alarm Suppression to deal with high
alarm situations like unit trips by temporarily but automatically removing certain
'flow-on' alarms from normal alarm views.
Decide whether you want to enable alarm shelving. Enabling alarm shelving
allows operators to temporarily remove alarms from normal alarm views. For
example, if some equipment is out of action for maintenance, operators can
temporarily remove alarms associated with this equipment from their current alarm
view.
Alerts can also be shelved in the same way.
Formulate a set of rules and guidelines for prioritizing alarms.
System alarm help is supplied with each release of Experion and can be tailored
for a customer's site. For more information about how to do this, see "Configuring
system alarm priorities and help" in the Station Configuration Guide.
Consider your alarm annunciation needs, such as buzzers and horns.
Decide whether you want to create alarm groups. Alarm groups provide an
alternative way of viewing alarms, which is not related to your asset model. For
example, you could create an alarm group to monitor alarms on all electrical
motors in your plant, regardless of their locations within the asset model.
Decide whether you want to create system alarm groups. Unless stated otherwise,
the configuration and usage of system alarm groups is the same as alarm groups.
However, system alarm groups can only include system points and other system
alarm groups. They can be used to create a hierarchy of dashboards for the System
Status display. For more information, see "Creating a dashboard hierarchy for the
System Status display" in the HMIWeb Display Building Guide.
Decide whether you want to create alarm trackers. An alarm tracker provides an
asset-based, graphical view of alarms over time that helps operators identify and
respond to abnormal situations like alarm floods. Alarm Tracker is an Experion
license option.
Consider using alerts for notifications whose urgency and priority are not high
