Alarm Banner ​

The newest unacknowledged alarm with its Acknowledge button and a "+N more" count, for the top or bottom of every screen.

In Studio ​

In Studio, double-click Alarm Banner in the Components category of the Components panel. It is added to the open view, where you can drag it into place.

When to use ​

Use Alarm Banner in a header or footer dock so an operator always sees the alarm that needs them, without opening the Alarm Table. Pick filled for the strongest look (priority 1 only by default) and counts for a header that shows totals per priority.

Properties ​

PropertyTypeDefaultDescription
Styleoutline, filled, countsoutlineHow it looks: outline (default, the ring takes the priority color), filled (filled in the priority color, for priorities up to Filled Up To) or counts (per-priority totals plus the newest alarm's text).
Filled Up To Priority1, 2, 3, 41The filled style applies to priorities 1 up to this one (default 1). Lower priorities fall back to the outline.
Source FilterString(none)Only alarms whose tag is in this folder or below. Accepts {view.params.X} and {page.params.X}. Set but empty or unresolved shows nothing; blank shows every alarm.
Ack Button TextStringAcknowledgeThe text on the Acknowledge button.
Text When ClearStringNo unacknowledged alarmsWhat the banner says when nothing is unacknowledged.

Binding ​

This component has no single value binding.

Acknowledge uses the same endpoint and permission as the Alarm Table: it is not offered on a read-only page, nor to an anonymous session unless the project allows anonymous acknowledge, and the gateway still enforces the role. A failed alarm fetch reads "Alarms unavailable", never "no alarms". In the designer the banner draws a sample alarm set so the style can be seen.
