Example: Creating plant objects and plant object types (RT Unified) - WinCC Unified

Task

You create plant object types from which you will create plant objects in the plant view in the next step. The plant objects represent the units and production lines of the brewery. These are the following elements in our example:

• Filling tank (unit)

• Conveyor (unit)

• Robot (unit)

• Bottling (production line)

• Packaging (production line)

Next, you define the "Communication driver" property of the interfaces.

Requirement

• The project is open.

• A SIMATIC S7-1500 PLC has been created.

• At least one program block is configured in the PLC.

• The "Brewery" plant view is created, assigned to an HMI device and open.

Procedure

1. To display the "Plant object types" task card, click the "Show plant object types" button under "Project tree > Plant objects".

2. Create a plant object type for each unit and assign the following names:

   • Conveyor

   • Robot

   • Filling Tank

   • Bottling

   • Packaging

3. Specify "SIMATIC S7 1200/1500" as communication driver for each plant object type.

4. As PLC tag, specify the function block that contains tags which match the unit.

5. Now create the following plant objects from the plant object types by dragging the respective plant object type to the plant view and adapting the name:

   • Packaging

   • Bottling

6. In the "Bottling" plant object, create the following lower-level plant objects by dragging the respective plant object type to the "Bottling" plant object:

   • Robot_1

   • Robot_2

   • Robot_3

   • Conveyor_1

   • Tank_1

7. In the "Packaging" plant object, create the following lower-level plant objects by dragging the respective plant object type to the "Packaging" plant object:

   • Robot_4

   • Robot_5

   • Robot_6

   • Robot_7

   • Conveyor_2

   • Conveyor_3

8. Under "Connection", assign each plant object the HMI connection and an instance data block as PLC tag.

Result

You have created plant object types for the units and production lines of the brewery. From the plant object types, you have created plant objects in the plant view.

The plant view should have the following structure:
