Property Mapping
The various names (for example, PrVal = Present_Value) for individual systems to be integrated must be mapped to a Function using a mapper for uniform display of objects based on Function. The number of Object Model properties of the individual subsystems may differ from Function (see the Object Models on System 3 under Examples 2).
Example 1: The Temperature Sensor Function is used for only one subsystem:

Example 2: The Temperature Sensor Function is used by multiple subsystems:

Although different property names are defined for the various subsystems, the Function Mapper allows for easy assignment of these names to the corresponding Object Model.
