because all workstations have Area A assigned. Consider lowering the priority of these alarms to ADVISORY until the end of the
commissioning process.
Reporting Alarms and Events to a Workstation
Device alarm and event reporting is no different than control module reporting. Alarm and event reporting to
workstations is determined by assigning areas to workstations. The workstation area assignment is all you need to do
to ensure that you have all of the information (device and process) for that area.
This is important so that ALL of the information about an area -- both the process and device information -- is available
at any workstation that is responsible for that area. That way the Event Chronicle has a complete record for that area,
and any user can drill into a graphic or tag and access all of the information.
This DOES NOT determine WHO views the device alarms. Who views the alarms is determined by filtering at each
workstation.
Now that all of the device (and process) information is assigned to a workstation, the next step is to decide what
priority of device and process alarms cause alarm annunciation to the users on that workstation.
Setting up WHO Sees Device Alarms
The priority of the alarms, and the settings at that workstation determine what alarms are annunciated on a particular
workstation. Annunciated means sound the horn and shown in the alarm banner, Alarm List display, etc.
There are two different approaches that can be used to adjust the device alarm filtering for a particular workstation:
D Adjust the default DeltaV Operate alarm settings in the UserRef/UserSettings file
D Adjust the individual device alarm priorities
By default, DeltaV Operator Stations have all process alarms are annunciated, and show up on the Alarm Banner, Alarm
List, graphical displays, etc. on all operator workstations. Also by default, the device alarms with priority settings below
WARNING (8) are NOT annunciated or shown in the alarm banner. The low priority device alarms can be shown in
graphics and on summaries defined to not be limited by the alarm settings.
The DeltaV Maintenance Station uses the same DeltaV Operate alarm setting for device alarm annunciation. This
license only shows device alarms on Maintenance Station graphics. NO process alarms are shown in the alarm banner
or ANY alarm summary.
Thus, device alarms and process alarms can be either combined and/or separated for specific user installations, based on
their operating philosophy.
Setting DeltaV Operate Device Alarm Annunciation Defaults
DeltaV Operate has default settings in the UserRef.grf file for what priority of device alarms will annunciate and show
in the alarm banner. The default DeltaV Operate alarm settings annunciate device alarms that are of the priority
WARNING (8) or higher. Device alarms below this priority will not sound the horn or show up in the alarm banner.
Operator Station displays can be configured to show any alarms reporting to that workstation. Along with typical
display configuration, alarm summaries can be configured to display alarms that match the alarm banner settings, or
user specified ranges. The standard AlarmSum display is configured to show all alarms reporting to that workstation
(see figure F‐8).
