Acknowledging alarms means confirmation of current alarms (alarm object in Alarm state) by the operator. Acknowledgement of an alarm changes its status to a Normal state. But you can also acknowledge the next alarm state – Unacknowledged. This state occurs for an Alarm type object which is defined as an acknowledgement-required alarm at its configuration in the D2000 CNF process, when the condition to raise alarm is not met.
To acknowledge an alarm
Alarm acknowledgement is presented by the change of the alarm graphic symbol to symbol. In case the acknowledged alarm is the last active one in the system then the visual and audible alert will stop after its acknowledgement.
