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].
