Configuring Alarm Settings
The Settings tab represent all settings that are common for all conditions and fields. You can configure alarm settings that are independent of the values on the Fields tab or alarm Conditions tab. See Alarm Types Overview for additional information.
Selecting an alarm type (Limit, Digital, Hi Limit, Lo Limit, etc.) displays the alarm pane. The following image shows an example of a configured Settings tab.
You configure individual setting values by typing the appropriate value or by clicking the S button to open the expression editor. The following table identifies each setting, its functional description, and default value.
