AlarmMostUrgentAcked custom property

The Boolean value of AlarmMostUrgentAcked indicates if the most urgent alarm associated with a symbol's measured value has been acknowledged or not.

During an active alarm state, the alarm border blinks when the most urgent alarm is acknowledged. Alarm Border animation remains around the symbol until the measured value returns to normal and the alarm is acknowledged.

Assign values to the AlarmMostUrgentAcked custom property

Alarm Border animation is primarily intended for managed applications that use ArchestrA automation objects, which include a set of aggregate alarming attributes. These attributes can be assigned as references to a symbol's set of Alarm Border animation custom properties.

Modern applications that use tag-based references do not have a comparable set of aggregate alarming attributes. References to your aggregate alarm data must assigned to the custom properties of Situational Awareness Library symbols that are part of tag-based Modern applications.
