| Sorting/Filtering |
| |
Operators can filter and sort alarm messages using alarm attribute identifiers included in the alarm messages as the keys. Engineering-less filters such as process alarm filter and plant-hierarchy filter can be used immediately. Users can define unique filters and flexibly create temporary filters. |

|
| Eclipsing |
| |
Alarm messages that are repeatedly activated by the same tag can be collapsed and displayed as a single line. Eclipsing reduces the number of alarm messages being displayed and allows operators to identify critical alarms easily. |
| |
|
| Shelving |
| |
Unnecessary alarms can be temporarily moved to “shelves”. Operators can shelve unnecessary alarms manually. Chattering alarms can be automatically moved to the shelves for a certain period of time or at a certain clock time. Similarly, alarms that match user-defined conditions can be automatically moved to the shelves. |

| Load Shedding |
| |
If too many alarms are displayed in a short period of time due to an unexpected event, predefined filters can be automatically activated to reduce the operators’ monitoring load. |
