Creating plant object types

Introduction

You create plant object types.

Then define the "Communications driver" property of the interface:

  • "<Internal communication>": Create data members for internal communication.

  • "SIMATIC S7 1200/1500": Use either function blocks or the PLC user data types of an S7-1500.

    You can add further data members to the linked structure.

Requirement

  • A project is open.

  • A SIMATIC S7-1500 PLC has been created.

Procedure

Create plant object types in the "Plant object types" task card.

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

  2. To create a plant object type, click "Add new plant object type".

    An empty plant object type is created.

  3. Rename the created plant object type accordingly.

  4. To edit the plant object type or create lower-level objects and members for the plant object type, double-click the plant object type in the "Plant object types" tab.

    The plant object type appears under "Interface".

    Note

    The "Communications driver" property is editable for the plant object types. The property "PLC tag" can only be edited with the communications driver "SIMATIC S7 1200/1500".
