1 Scope
This part of IEC 62656 provides an application guide for the data parcels specified in IEC 62656‑1 and used for the definition of a domain data dictionary that may be imported from
and exported to the IEC common data dictionary, or IEC CDD for short, maintained as
the IEC 61360‑4 database [1] 3. This part of IEC 62656 provides instructions for the interpretation and use of the technical specification
defined in IEC 62656‑1 within a software application, to avoid misuse of the data constructs available in
IEC 62656‑1.
This application guide contains the following items:
-
• principal information for implementing data parcels for data dictionaries from/to the IEC CDD,
-
• typical examples of how to implement typical features on data parcels,
-
• extension of conformance classes for implementation of parcel-based systems to import/export data parcels from/to the IEC CDD.
The following items are outside the scope of this part of IEC 62656:
-
• procedures for building IEC 61360 compliant domain data dictionaries,
-
• semantics of a standard data dictionary itself,
-
• theoretical explanation of the logical structure of data parcels, which is considered in IEC 62656‑1,
-
• interface for the common information model (IEC 61970‑301 [2]), which is considered in IEC 62656‑3 [3].
