To set up alarming on a component you need to add an alarm extension to the component’s property sheet. Refer to About alarm extensions for more details about the alarm extensions. Alarm extension types must match their parent component type. For example, an OutOfRangeAlarmExt goes with a Numeric point type and a BooleanChangeOfStateAlarmExt goes with a Boolean point type. For a list of alarm extensions types and their associated point types, refer to Types of alarm extensions.

Alarm extensions are contained in the alarm Palette, as shown in Figure 188.

For details on adding extensions to a property sheet, see To add an extension to a component property sheet view:. Once the extension is added, configure the extension to meet your alarming requirements. Refer to About alarm extension properties for more details.
