4.3 Data Broker
The Data Broker decouples individual components from each other
and distributes the data streams between the interfaces. The
targeted forwarding of the data ensures a high level of functionality
between the data sources and data sinks of the module.

Internal mapping by the Data Broker
Mapping
You have the option to define the allocation (mapping) yourself. This
allows you to define which input register the Data Broker should
accept data from and which output register it should transfer data to.
You can define up to 8 register areas with freely definable lengths in
the respective output register area for each of the interfaces. Any
register area of the same length is assigned to the output register
areas from one of the input register areas of all interfaces. Here, the
8 target areas are always on consecutive output register positions,
starting with the lowest register address for the respective interface.
