Freeze the Alarm Control grid

You can freeze the Alarm Control to prevent the Alarm control tree from being updated with any further changes.

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

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

The Alarm Control unfreezes automatically if one of the following changes:

• Alarm Mode

• Alarm Query

• Filter
