Freeze and unfreeze the alarm grid

You can freeze the AlarmApp to prevent the AlarmApp tree from being updated with any further changes.

For example, if new alarms occur while the AlarmApp is frozen, the new alarms are only shown after you unfreeze the AlarmApp.

You can configure a time period after which the AlarmApp automatically unfreezes to avoid the AlarmApp being unknowingly frozen. For example, the operator leaves the workstation and returns without realizing that the AlarmApp is still frozen.

The AlarmApp unfreezes automatically if one of the following changes:

• Alarm Mode

• Alarm Query

• Query Filter

After you unfreeze the AlarmApp, the grid updates with the new alarm records and any other updates while the grid was frozen.

To freeze or unfreeze the AlarmApp grid

1. Right-click the AlarmApp grid. The shortcut menu appears.

   

   A check mark next to the Freeze option indicates if the grid is currently frozen.

2. Click Freeze. The AlarmApp grid is either frozen or unfrozen.
