Alarm Banner

Functional explanation

AlarmBannerObject shows the live alarm list on a page. It is used where active alarms must remain visible to the operator without opening a separate viewer page.

The object is useful on overview pages, control room displays, and faceplates where active alarm awareness is required during operation. It presents alarm data in a tabular banner layout with configurable columns and acknowledgement support.

Use it when active alarms should remain visible inside the current page instead of only in the dedicated viewer page.

Row Buttons

Each alarm row ends with up to three buttons. A button is shown only to users whose user group holds the matching right; for other users its column is hidden, header included.

When Part 11 compliance mode requires an electronic signature for the action key Alarm.Ack or Alarm.Shelve, the Electronic Signature dialog opens before the acknowledgement or the shelve is applied, as in the Alarm Viewer. Shelved alarms and alarms suppressed by design are not listed in the banner; the Suppressed Alarms view of the Alarm Viewer lists them.

Style

The Style setting in the Alarm Filtering group selects how the banner shows its alarms. A new Alarm Banner is created as Flat. A banner created before the setting existed shows Classic until Style is changed.

In both styles the Severity column shows the severity name, a column name that was not changed is shown in the operator's language, a text cell shows its full text as tooltip, and an empty banner shows No alarms. The rows are updated in place when alarms change, so a button keeps its position while the operator points at it.

To change a column width, select the Alarm Banner in the design environment and drag the right border of the column, in the column header or next to the rows. The border follows the pointer, and the widths are saved with the page. In Flat, the column borders are marked in the column header while the banner is selected.
Classic: while the table is narrower than the banner, the column gets wider or narrower and the table with it. When the table fills the banner, the width moves between the column and the next column, and the other columns keep their widths. The narrowest width of a column is the width of its longest word. When the banner is resized, the table adapts to the new width. When the table is wider than the banner, the columns are at their narrowest width and the columns on the right are cut off; hide columns or make the banner wider to show them.
Flat: the width moves between the column and the next column, so the table keeps the width of the banner.
Each style keeps its own column widths, so switching the Style and back restores them.

Header Strip

The header strip above the column headers shows the Table Name when one is set, the filter, the number of active and unacknowledged alarms, and Acknowledge All. For users with the Alarm All Acknowledge Right, Acknowledge All acknowledges every unacknowledged alarm listed in the banner through the same acknowledge dialog as the row button.
Show Header Strip in the Alarm Filtering group shows or hides the strip in both styles. Until it is changed, it follows the Style: checked in Flat and cleared in Classic, so a Classic banner created before the setting existed keeps its look. When it is cleared, the column headers are at the top of the banner.
The texts of the strip follow the operator's language. The Table Name is translated through the project language texts in the same way as the column names, and the Project Language Texts Export on the Parameters page includes it.
