Events
Events
The Events page allows you to view and analyze all events recorded by the system for one or more plants within a selected time range. It is intended for operators.
What are events
An event represents information recorded by the system during plant operation.
Events are grouped into three categories:
- Status indicate the operational state of a device or subsystem
- Alarm indicate alarms or abnormal conditions
- Command represent commands or actions executed on the system
All event types are displayed together in the same view.
Plant and time range selection
To view events, you must:
- Select one or more plants from the tree in the toolbar
- Select a time range (start and end date/time)
- Click Search events
Event list
After the search, events are displayed in a table. For each event, information such as the following is available:
- date and time
- plant
- subsystem, section, and device
- event type (Status, Alarm, Command)
- name and description
- value and related message
- data validity
- alarm status and acknowledgment (ACK)
The total number of events found is shown above the table.
Filters and navigation
You can:
- apply filters to limit the displayed events
- reset filters with a single button
- navigate through result pages
- change the number of rows per page (options: 50, 100, 200, or 500 rows)
Filter types
The table supports different filter types depending on the column:
| Filter Type | Columns | Description |
|---|---|---|
| Multi-select list | Plant, Subsystem, Section, Device, Type, Name, Valid, Alarm, ACK, User, Level, Agent | Select multiple values with search functionality |
| Date filter | Timestamp | Filter by date range |

Active filters indicator
The toolbar displays:
- Number of active filters
- Details of each active filter

Advanced filters
The events table supports filtering on all columns, allowing precise refinement of the displayed results.
The following filters are especially useful:
- Alarm
Allows filtering events based on the alarm state (active or inactive). - ACK
Helps quickly identify:- unacknowledged alarms (Not ACK)
- acknowledged alarms (ACK)
- User
Shows the user who executed a command or action, when available.
Useful for tracing manual operations. - Agent
Indicates the system or process that generated the event.- If the field is empty, the event was written by the standard automatic data acquisition process
- If populated, it identifies a system or process that generated the event
Color legend
The page includes a legend explaining the meaning of the colors used.

Frequently asked questions
Why don't I see any events?
Make sure at least one plant and a valid time range are selected.
Why is the number of events very high?
The system may contain hundreds of thousands of events. Use filters and shorter time ranges to refine the search.
Are Status, Alarm, and Command separated?
No. All event types are shown together, but they are distinguishable by type and color.
How do I filter for unacknowledged alarms only?
Use the ACK column filter and select only "false" (or Not ACK) to see all unacknowledged alarms.
Can I search within a filter?
Yes. Multi-select filters include a search box that allows you to quickly find values by typing. The search is case-insensitive.
Is my column layout saved?
Yes. Column order, width, and visibility are automatically saved in your browser and restored when you return to the page.
How can I restore the original column configuration?
When you move or hide columns, the Reset columns button automatically appears in the toolbar. Clicking it restores all columns to their default visibility and order.
What do the different text colors mean?
The colors indicate the event state. Click on the legend icon in the toolbar to see a full explanation of all colors used.
