Overview
In object-oriented configuration, as in device-specific configuration via the alarming, events from the monitoring function in WinCC are displayed in form of alarms. The alarms can be acknowledged by the operator and, if necessary, logged. To do this, configure alarms that are separated into alarm classes.
For plant objects you can configure the following alarms that are used to monitor the plant:
-
Discrete alarms: Display status changes
-
Analog alarms: Display limit value violations (value changes),
Configure bit or analog alarms for plant object types on the basis of internal or external data members. From these plant object types you create plant objects.
If you have configured an alarm system for plant objects you can display the hierarchy path of the alarm source and the alarm status of a line or a machine in runtime, filter the alarm control by plant objects and navigate to the alarm source.
You can also filter the most frequently occurring alarms by plant object and only permit the alarm of the respective object and all lower-level objects to be displayed.
Configuration steps
In general, proceed in the following order when configuring the alarms for the plant objects:
-
Configure plant object types
-
Configuring bit or analog alarms for plant object types on the basis of data members.
-
Creating plant objects from plant object types
-
Configuring alarm control in a screen
-
Configuring "Plant view" control as companion control for the alarm control.

Note An alarm is linked to the respective plant object type. If you delete the plant object type the alarm will also be deleted. |
Configuring an alarm view
The alarm view is configured for a screen. Current or logged alarms are displayed in the alarm view in runtime. More than one alarm can be displayed simultaneously, depending on the configured size. Configure the criteria for alarm filtering.
You can also configure multiple alarm views with different contents and in different screens.
