When an alarm is reported to the CAS, its state is "unacknowledged." This means that the alarm is new and that a user or the system has not acknowledged its presence. In the alarm view, unacknowledged alarms are identified by a colored bell representing the alarm state. When an alarm is acknowledged, the bell disappears. In the example the alarm is unacknowledged, as evidenced by the bell icon.
Example
On a CygNet Studio/Vision screen, intrinsic tools can be configured to blink to indicate if the tool's point has an unacknowledged alarm.
Note: Alarm blinking is available only for points created using the CygNet Enhanced Point Scheme (Point Scheme number 1 - 15). The blinking feature is not available for points created using the default CygNet Standard Point Scheme (Point Scheme number 0).
You can acknowledge a single alarm, multiple alarms, visible alarms or all alarms. You can configure the CAS to automatically acknowledge based on certain criteria. See Alarm Auto Configuration for more information.
