This part of IEC 62453, which is a technical report, defines how the common FDT principles are implemented based on the Microsoft1 COM technology, including the object behavior and object interaction via COM interfaces.

This part specifies the technology-specific implementation of the protocol-specific functionality and communication services.

This part of IEC 62453 is informative, however when this part is applied its requirements need to be implemented as specified.

This part specifies FDT version 1.2.1.
