Alarm presentation
DeltaV Live provides several alarm components and features to help you customize the operator interface and manage how alarms are presented to operators. These components and features help operators to maintain situational awareness of abnormal conditions and respond efficiently to their alarms. This topic explains these components and features.
The alarm list
The alarm list provides a list of the active alarms in an operator's scope of responsibility and the means for operators to respond efficiently to those alarms. Graphics Studio provides four DeltaV-installed alarm list displays: the Alarm List, Alarm Summary, Suppressed Alarm List, and Batch Alarm List displays. An alarm list graphic element, which can be used when creating your own displays, is also provided. The alarm list graphic element offers various configuration options, including its look and feel, which interactions are available for operators to respond to alarms, and the context for the alarms. You can also configure the alarm list to dynamically adjust its context online, so that the same list could show alarms for a different area, unit, equipment module, control module, device, or hardware node.
Dual- and quad-monitor layout templates are pre-configured with two alarm lists, each on a separate screen. Single-monitor layout templates do not contain an alarm list.
The alarm banner
The Alarm Banner display provides operators with the means to maintain awareness of the most important alarms in their scope of alarm responsibility and the means to respond to those alarms. DeltaV Live provides four DeltaV-installed Alarm Banner displays, two for Batch displays and two for non-Batch displays. Single-monitor layout templates are pre-configured with one alarm banner, while dual- and quad-monitor layout templates are pre-configured with two alarm banners, each on a separate screen. Like other displays, the alarm banner displays are referenced from a display frame on the screen. The second alarm banner is used to extend the alarm banner across multiple screens while maintaining continuous alarm numbering.
The alarm rollup
- Alarm roll-ups show a count of active alarms in modules, devices, and nodes associated with either the display's configured plant hierarchy (area, unit, or equipment module) or primary control display.
- The alarm rollup count can be configured to do one of the following:
- show all active alarms
- filter alarms in the same manner as the alarm banner (per alarm thresholds)
- The alarm roll-up includes alarms from both the parent display and its child displays (according to the display set hierarchy).
- The alarm roll-up color indicates the top alarm's priority.
