Electricity meters commonly implement Device Language Message Specification and Companion Specification for Energy Metering (DLMS/COSEM) standardized in the IEC 62056 series. Head-End Systems (HES) for metering systems often use the Common Information Model (CIM), standardized in IEC 61968-9, to communicate with other enterprise systems such as a Customer Information System (CIS) or Outage Management System (OMS).
Every system that uses both DLMS/COSEM for the meters and CIM for the enterprise interface must necessarily implement a mapping from one to the other. While this has been described in IEC TS 62056-6-9, this work is to show a concrete example of how this mapping might be accomplished and to document some of the ambiguities and difficulties encountered along the way.
