Overview
The configuration of screens for operating and monitoring is also available to you in object-oriented configuration. This means that you are working in two areas, under "Project tree> Devices" and "Project tree > Plant objects > Visualization". Here you work with both screens and faceplates that also support the type-instance concept.
In the area "Project tree > Devices", configure screens for HMI devices as usual. In the screens, also configure companion controls that are relevant for the display of screens of the plant objects.
In the "Project tree > Plant objects > Visualization" area, you configure screens for plant objects.
In the "Plant object types > Visualization" area, configure faceplates for plant object types.
In the areas under "Project tree > Devices" and "Project tree > Plant Objects > Visualization", the same predefined screen objects are available in the "Toolbox" task card.
When configuring faceplates, a minimized tool area is available under "Toolbox".
Configuration options
Under "Project tree > Devices", you configure a screen for the created HMI device with the "Plant overview" control and one of the companion controls, such as a screen window. In runtime, navigate the plant structure to the plant objects via the "Plant overview" control. The screen windows in the plant overview display the screens that you have previously configured for the plant object.
The companion controls are connected to one another and supplement one another in displaying the data values.
The following controls can act as companion control for the plant overview:
-
Alarm control
-
Screen window
-
Calendar control (when using the WinCC Unified Calendar option)
When required, configure controls as usual, e.g. screen windows, alarm control, or trend control. Select the specific plant object in the plant hierarchy as data source for the alarm control and trend control. Configure the alarm control and trend control for plant objects on the basis of the data members of the plant object types. The procedure for configuring these controls does not differ from the procedure for the device-specific configuration.
The following options are available in runtime:
-
Display the hierarchy path of the alarm source
-
Display the hierarchy path of the trend values
-
Filter the alarm control by plant objects
-
Display process values for the selected plant object
Use the "Visualization" tab for the direct visualization of plant objects and plant object types. You can create one screen for each plant object, and you can link one faceplate type for each plant object type. The type-instance concept is used for configuring the screens for plant objects and plant object types. All relevant elements are contained in the faceplate type of a plant object type. Drag a plant object into the screen. A faceplate container is created. For example, several faceplates can be integrated into one visualization of a higher-level plant object.
Configuration steps
In general, proceed in the following order when configuring the screens for your plant:
-
Configure plant object types.
-
Configure faceplates for plant object types.
-
Create plant objects from plant object types.
-
Create screens for plant objects.
-
For the display in runtime, configure the "Plant hierarchy" and "Screen window" controls in a screen of the HMI device.
Displaying plant objects and plant object types
In general, you do not have to create a screen for each plant object. Create an overview for the higher-level plant object. Then create faceplates for the plant object types and drag them to the overview screen of the higher-level plant object using drag-and-drop.
If the screens of the plant objects need to differ from the screens used for the plant object types, you can use the faceplates of the plant object types as a basis and configure additional elements.
In runtime, select a plant object in the "Plant overview" control to display its screen.
