Alarm Handling

arrow1_rotationAcknowledgement arrow1_rotationAlarm States arrow1_rotationIndications

When an input, output or value in a connected device is configured to generate an alarm, Operator Display allows you to view and acknowledge the alarm. Inputs, outputs or values can be configured to generate an alarm when it is, for example, out of range or in a fault state.

On the Alarms screen, active alarms and reset alarms that have not been acknowledged are displayed. On the Alarm screen you also get information such as the alarm state, the name of the input, output or value generating the alarm, and the alarm message. For more information, see Alarms Screen .

Acknowledgement

When you acknowledge an active alarm, you let other users know that you have seen and taken responsibility for the issue causing the alarm. Acknowledging an alarm does not necessarily mean that you are personally solving the cause of the alarm. When you acknowledge an an active alarm the color and icon of the alarm in the Alarms pane changes. You also acknowledge reset alarms to remove them from the Alarms screen. For more information, see Acknowledging an Alarm .
