scope:

This part of IEC 62056, which is a Technical Specification, describes how in the utility environment an ERP system or a third party system can exchange information with a metering system. In particular, this Technical Specification covers the mapping between information interchange messages of a CIM-based ERP or third party system and a DLMS/COSEM-based metering system.

A typical metering system would comprise a HES and end devices such as meters as well as tariff and load control devices. There may be intermediate devices in the metering system such as NNAPs and LNAPs, as described in the smart metering architecture of IEC 62056-1-0. These intermediate devices are outside of the scope of this Technical Specification.

CIM ReadingType, EndDeviceControlType and EndDeviceEventType codes as specified in IEC 61968-9 are mapped to OBIS codes as specified in IEC 62056-6-1.

In some cases the CIM models and COSEM models are differently structured, in which case it is not possible to provide a one-to-one mapping between the OBIS codes and the CIM data type codes. In these cases the mapping is thus performed between the CIM UML object attributes and the COSEM object attributes (see 4.3.4 UC3).

CIM EndDeviceControlType codes as specified in IEC 61968-9 are mapped to COSEM IC attributes and methods as specified in IEC 62056-6-2.

CIM verbs and nouns as specified in IEC 61968-9 are mapped to DLMS service requests and responses as specified in IEC 62056-5-3.

Only the most commonly used UCs are given in order to illustrate possible applications. Extensions may be considered in future editions.
