Dismiss alarms at runtime

When an alarm occurs, the run time operator (or system) can acknowledge the alarm to indicate that they are aware of the alarm. An acknowledged alarm that has returned to a normal value will continue to be displayed if the latching feature has been enabled for the Galaxy. With latching enabled, an acknowledged alarm that has returned to normal condition will be placed in the LATCHED alarm state.

LATCHED alarms can be displayed in the current alarms mode to show that the alarms did occur. Alarms go to the LATCHED state if:

• You ACK an alarm from UNACK_RTN state.

  Or

• You return an alarm from ACK state.

To view the LATCHED state, you have to enable the LATCHED state under the global settings. For more information, see the "Enable a Latched State" in the AVEVA OMI help.

You can dismiss the LATCHED alarms to remove the LATCHED alarms from the current mode of the Alarm Client Control grid. The dismissed LATCHED alarms would be visible in the recent mode of the Alarm Client Control.

To dismiss selected alarms

1. Select one or more alarms in LATCHED state.

2. Right-click anywhere on the grid and select Dismiss Selected.

The selected alarm is removed from the grid.
