Alarm Journal
The append-only history of every alarm lifecycle event — raised, acknowledged, returned to normal, shelved, suppressed, restored — searchable and filterable, and fast over months of data.
Reach for it when you need:
- Shift handover: what happened, and what is still outstanding
- Incident investigation: the exact order of events and who acknowledged what

Properties
Any property can be bound to a tag, another component's property, or a query.

Events
Attach event actions to these in the Event Manager.
| Event | Label | Group | Payload |
|---|---|---|---|
click | Click | Mouse | The DOM event. |
dblclick | Double click | Mouse | The DOM event. |
contextmenu | Right click | Mouse | The DOM event. |
mouseenter | Mouse enter | Mouse | The DOM event. |
mouseleave | Mouse leave | Mouse | The DOM event. |
contextmenu fires your configured actions at runtime only — in LiveView and in preview. On the Designer canvas the right-click is captured to open the Event Manager, so testing it there will not run your actions. Test right-click in preview.
Notes
The journal is the alarm record, not the security audit journal. Use the audit journal for "who changed the setpoint"; use this one for "when did it trip".
