Full title and description

Electricity metering data exchange - The DLMS/COSEM suite - Part 9-7: Communication profile for TCP‑UDP/IP networks. This standard specifies the DLMS/COSEM communication profile designed for operation over TCP and UDP/IP network environments, detailing addressing, service mapping and profile-specific parameters for COSEM application layer services.

Abstract

IEC 62056-9-7:2013 defines a communication profile within the IEC 62056 (DLMS/COSEM) family for use on TCP/UDP/IP networks. It covers the targeted communication environments, profile structure, identification and addressing schemes, mapping to supporting layer services, specific COSEM application-layer service parameters and implementation considerations or constraints. The document provides normative references and guidance needed to implement DLMS/COSEM over IP-based networks.

Scope

IEC 62056-9-7:2013 specifies the DLMS/COSEM communication profile tailored to TCP and UDP over IP networks. The scope includes definition of targeted communication environments, the structure of the profile(s), identification and addressing schemes for devices, the mapping of COSEM application-layer services onto underlying transport and network services, profile-specific service parameters, and implementation constraints and considerations for reliable operation over IP-based networks.

Key topics and requirements

• Definition of targeted TCP/UDP/IP communication environments and assumptions.
• Structure and variants of the communication profile(s) applicable to IP networks.
• Identification and addressing schemes for DLMS/COSEM devices on IP networks (how devices are located and addressed across IP).
• Mapping of COSEM application‑layer (AL) services to supporting layer services provided by TCP/UDP/IP and related transport layers.
• Specification of communication‑profile specific service parameters for COSEM AL services (timeouts, retries, addressing fields, port usage, etc.).
• Specific considerations and constraints for reliable operation (security considerations, fragmentation, transport limitations and recommended practices).
• Normative references to other IEC 62056 parts and related standards required for full implementation.

Typical use and users

This standard is used by meter manufacturers, firmware and device software developers, utility communications engineers, system integrators and test laboratories implementing or validating DLMS/COSEM over IP networks. It is applied when designing meters and head‑end systems that communicate via TCP/IP or UDP/IP (for example, Ethernet, cellular IP, or routed network segments) and when integrating DLMS/COSEM stacks into IP-based AMI/MDM infrastructures.

Related standards

IEC 62056-9-7 is part of the IEC 62056 DLMS/COSEM suite. Key related parts include IEC 62056-5-3 (DLMS/COSEM application layer), IEC 62056-47 (COSEM transport layers for IPv4 networks) and other communication profiles (such as PLC or neighborhood network profiles). National and regional adoptions (EN/BS/UNE, etc.) implement this IEC part identically.

Q: What does it cover?

A: It covers targeted communication environments, profile structure, identification and addressing schemes, mapping of COSEM application-layer services to supporting transport/network services, profile-specific service parameters and implementation constraints for IP networks.

Q: Who typically uses it?

A: Meter manufacturers, firmware and protocol-stack developers, utilities and communications engineers, system integrators, test houses and certification bodies involved in implementing or validating DLMS/COSEM over IP networks.

Q: Is it current or superseded?

A: The 2013 edition (Edition 1.0) is the published IEC edition; as with all standards, practitioners should verify with the IEC or national standards body for any amendments or newer editions before relying on it for new deployments. National adoptions published in 2013–2014 mirror this edition.
