This is an extended version of the metadata function that provides complete information about
the ADIs. This extended version is needed to describe more complex data types such as
Structures.
The information provided is a transparent representation of the attributes available in the host
Application Data object (FEh). See the Anybus CompactCom 40 Software Design Guide for
more information about the content of each attribute.
The ADI metadata is static during runtime.
