Displaying alarms for plant objects in runtime (RT Unified) - WinCC Unified

Introduction

The "Alarm control" object displays alarms that occur during the production process in a plant.

Depending on your configuration, the following possibilities are available to you in runtime:

• Display hierarchy path of the alarm source

• Filter alarm control by plant objects

• Display alarm status of a line

• Navigate to the alarm source

• Display the most frequently occurring alarms, filtered by plant object or plant object type

Requirement

• The plant hierarchy has been created and assigned to a device.

• An alarm control with the filter "Range" is configured in the screen by the assigned device.

• Runtime is active.

• The alarm view has been configured.

• Runtime is active.

Filter alarms by plant objects

1. If you want to filter alarms by plant objects, click "Selection display" in runtime.

   The "Selection" dialog opens.

2. Under "Criterion", select the criterion "Range".

   All plant objects of the plant hierarchy are displayed.

3. Select the respective plant object to which you want to display the alarms.

   

   Only alarms for the selected plant object are displayed in the alarm control.

Display alarm context of the plant objects

For analysis purposes, display the value range of the resulting data using the context data.

The evaluation is relevant, for example, in connection with the WinCC Unified Performance Insight to analyze the effectiveness or the fault rate of the plant.

1. In the alarm control, click "Select context".

   The "Alarm context" dialog box opens.

2. In the "Plant objects" selection list, select the respective plant object whose data you want to display in the alarm control.

3. In the "Context" selection list, select the data assigned to the plant object.

   The list of the logging data appears under "Logged context values".

4. Select the value that you want to display.

   

5. Confirm with "OK".

   The alarm control displays the alarms that match your selection.

   Note Make sure that the filter settings match the setting of the alarm context. If no alarms appear in the alarm control, check your settings by clicking "Selection display".
