PlantWeb Alerts
Fieldbus devices detect and report their device alarms
to a DeltaV system (or other host system). This
includes detecting whether an alert condition is active,
reporting the alarm to DeltaV and later clearing the
alarm when the condition is no longer active. Whether
a particular alert condition can be suppressed,
disabled or configured off-line are all determined by
the device.
For Fieldbus, the DeltaV system is responsible for
knowing which devices have alarms, ensuring that
alarms are properly represented (such as after
controller switchovers) and reporting to operators,
Event Chronicle, AMS, OPC Alarms and Events
server, etc. So the only alarms DeltaV shows for a
Fieldbus device are those the device has defined as
alarms and has reported to DeltaV.
All device alarms are configured and processed in the
DeltaV system identically to process alarms. This
means that how the alarms are communicated within
the system, what workstations are notified, alarm
annunciation, graphical representations, event
recording, acknowledgement, etc. are identical for
process and device alarms. This ensures that device
alarms and process alarms are available to all users
and applications in a consistent fashion.
Setting up PlantWeb Alerts
This section walks you through the steps and
considerations to implement PlantWeb alerts.
DeltaV Hardware and Software
Requirements
The first step to implement PlantWeb alerts is to have
the correct hardware and software:
Figure F-5. Alarms & Display Tab
DeltaV v6.3 or later

While device alerts are
supported on all fieldbus devices, devices that offer
PlantWeb alerts provide significantly more useful
information.

Initial Device Setup
When new FF devices are commissioned on the
DeltaV system, device alarms are automatically
enabled and default priorities are assigned to the
alarms. Select properties on the device, then the
Alarms and Displays tab, as shown in figure F-5 to
view whether device alarms are enabled on a
particular device.
The Enable Device Alarms configuration option
modifies the device configuration. Thus changing this
setting requires a download to the device. Devices that
