Full title and description

IEC TS 62056-6-9:2016 — Electricity metering data exchange. The DLMS/COSEM suite. Part 6-9: Mapping between the Common Information Model message profiles (IEC 61968-9) and DLMS/COSEM (IEC 62056) data models and protocols. This Technical Specification describes how an ERP or other CIM-aware system can exchange information with a DLMS/COSEM-based metering system by defining the mapping rules and translation patterns between CIM message profiles and DLMS/COSEM services and objects.

Abstract

This Technical Specification provides a mapping framework and concrete examples to translate information interchange messages from CIM-based systems (as specified in IEC 61968-9) into DLMS/COSEM requests and responses (IEC 62056). It defines reference use cases, translation rules, data model correspondences and sample message flows to support interoperability between enterprise/third‑party systems and metering devices.

Scope

The document covers the mapping between CIM message profiles (IEC 61968-9) used by enterprise and distribution/utility systems and the DLMS/COSEM data models and communication services defined in IEC 62056. It addresses reference architectures, translation components (proxy/translator roles), mapping rules for common object types (meter reading, registers, tariff structures, events), and example use cases including tariff and two‑rate TOU scenarios. The scope is limited to mapping and translation guidance rather than prescribing a specific integration product.

Key topics and requirements

• Definition of a reference environment and actor roles (CIM_System, CIM_DLMS/COSEM_Translator, DLMS/COSEM_Server).
• Mapping rules from CIM message elements to DLMS/COSEM objects, attributes and methods.
• Translation patterns for common metering functions: reading retrieval, register mapping, tariff and TOU data, and event/alarms.
• Message flow examples and sequence diagrams for request/response translations.
• Annex with an informative example (e.g., 2‑rate TOU tariff) to illustrate mappings and payloads.

Typical use and users

Intended users include utility architects, system integrators, meter manufacturers, software vendors implementing DLMS/COSEM clients or CIM‑aware enterprise interfaces, and consultants working on smart‑meter integration projects where enterprise systems must interoperate with DLMS/COSEM metering infrastructure. The TS supports design and verification of translation/proxy components and integration testing.

FAQ

Q: What is this standard?

A: IEC TS 62056-6-9:2016 is a Technical Specification that defines mapping rules and translation guidance between Common Information Model (CIM) message profiles and DLMS/COSEM data models and protocols to enable information exchange between enterprise systems and metering devices.

Q: What does it cover?

A: It covers reference architectures, mapping of CIM elements to DLMS/COSEM objects and services, translation patterns, example message flows and an informative annex (for example, a 2‑rate TOU tariff mapping). It focuses on interoperability guidance rather than prescribing a single implementation.

Q: Who typically uses it?

A: Utility IT architects, system integrators, meter manufacturers and software vendors implementing DLMS/COSEM clients or CIM interfaces; also consultants and test labs validating integrations.

Q: Is it current or superseded?

A: The Technical Specification was published in May 2016 (Edition 1.0). According to the IEC record it carries a stability date through 2026, so as of February 26, 2026 it remains the published TS and is not listed as superseded. Users should check IEC publications for any amendments or later parts beyond that date.

Q: Is it part of a series?

A: Yes — it is part of the IEC 62056 DLMS/COSEM suite (multiple parts covering object models, communication profiles and application layers) and specifically maps to CIM message profiles defined in the IEC 61968 series.

Q: What are the key keywords?

A: DLMS, COSEM, CIM, mapping, translator, meter data exchange, smart metering, tariff, TOU, interoperability.
