Configuration concept (RT Unified) - WinCC Unified

Requirements

• You have experience in configuring with WinCC and STEP 7.

• The TIA Portal project has been created.

• The WinCC Unified PC RT HMI device has been created.

• A SIMATIC S7-1500 PLC has been created.

• Data blocks are configured in the PLC.

Workflow for configuration

The starting point for the definition of a standardized object-oriented plant model in object oriented configuration is the existing plant structure.

If you want to create a plant structure, use the following sequence of steps as a guide:

• Analyze the plant structure and break it down into units and components (plant objects)

• Identify required plant object types

• Define data of the plant object types based on FBs and PLC UDTs

• Define hierarchical plant view using instances

• Create a target system

• Map the plant structure

• Position plant objects in the plant structure

• Add functional facets to object types, e.g. assign shift calendars for all machines of a line or plant

Differences between device-oriented and object-oriented configuration

In technology- and object-oriented configuration, you work with objects with relevant names instead of individual tags or faceplates, for example.

You have access to all objects and their properties, methods, etc. in the hierarchy, independent of HMI device assignment.

The equipment from different products and versions is integrated in the object-oriented configuration.

Using multiuser engineering

If you use multiuser engineering in object oriented configuration, you can save your changes only in the server project view. You cannot check the changes you make in the local session into the server project.
