Full title and description
IEC 62056-47:2006 — Electricity metering — Data exchange for meter reading, tariff and load control — Part 47: COSEM transport layers for IPv4 networks. This part of IEC 62056 specifies the COSEM transport-layer profiles for use over IPv4 networks, providing both a connection‑less (UDP-based) and a connection‑oriented (TCP-based) transport layer that deliver OSI‑style services to the COSEM application layer.
Abstract
IEC 62056-47:2006 defines transport-layer behaviour and service interfaces for DLMS/COSEM communication over IPv4. It describes a UDP-based connection‑less transport profile and a TCP-based connection‑oriented transport profile, the service primitives offered to the COSEM application layer, and protocol-level requirements needed to map COSEM services onto standard IPv4/TCP/UDP mechanisms. The standard is intended to support reliable and interoperable meter reading, tariff management and load control across IP networks.

Scope
This part of IEC 62056 specifies the transport layers for COSEM communication profiles intended for use on IPv4 networks. It defines both a connection‑less transport layer using the User Datagram Protocol (UDP) and a connection‑oriented transport layer using the Transmission Control Protocol (TCP). The document covers the services provided to the COSEM application layer, the mapping of COSEM primitives to IPv4/TCP/UDP constructs, and protocol behaviour necessary for meter reading, tariff management and load control over IP networks.
Key topics and requirements
- Definition of COSEM transport service primitives and the service interface to the COSEM application layer.
- Specification of a connection‑less transport profile based on UDP (packet formats, addressing/port usage, service semantics).
- Specification of a connection‑oriented transport profile based on TCP (connection setup/teardown, sequencing, acknowledgements and reliability behaviour).
- Mapping rules between COSEM transport-layer services and standard IPv4/TCP/UDP mechanisms.
- Protocol timers, retransmission behaviour (where applicable), and error handling expectations for interoperability.
- Requirements to support DLMS/COSEM applications for meter reading, tariff and load control over IPv4 networks.
- Conformance and interoperability considerations for implementers (expected behaviours to achieve inter‑vendor compatibility).
Typical use and users
Primary users are electric meter manufacturers, utility communication engineers, system integrators, smart‑grid solution providers, and test/laboratory organisations. The standard is used when implementing DLMS/COSEM stack transport layers over IPv4 — for example in IP‑connected smart meters, data concentrators, head‑end systems and gateways that require interoperable meter‑to‑system transport behaviour.
Related standards
IEC 62056 is a multi‑part family (DLMS/COSEM). Closely related parts include IEC 62056-21 (direct local data exchange), IEC 62056-53 (COSEM application layer), IEC 62056-62 (interface classes), and the later consolidated/restructured part IEC 62056-4-7:2015 which replaced IEC 62056-47:2006. The transport layer definitions rely on standard Internet protocols (IPv4, TCP, UDP) and are used in conjunction with DLMS/COSEM application specifications.

FAQ
Q: What is this standard?
A: IEC 62056-47:2006 is a part of the IEC 62056 (DLMS/COSEM) suite that defines COSEM transport-layer profiles for operation over IPv4 networks, specifying both UDP‑based and TCP‑based transport behaviours for meter communication.
Q: What does it cover?
A: It covers the COSEM transport service interface and two transport profiles (connection‑less via UDP and connection‑oriented via TCP), mapping rules to IPv4/TCP/UDP, expected protocol behaviour (timers, retransmissions, error handling) and interoperability considerations for meter reading, tariff and load control applications.
Q: Who typically uses it?
A: Meter vendors, utilities, system integrators, gateway designers and test labs implementing or validating DLMS/COSEM over IPv4 networks use this standard to ensure interoperable transport‑layer behaviour.
Q: Is it current or superseded?
A: IEC 62056-47:2006 has been withdrawn and was replaced by IEC 62056-4-7:2015. The withdrawal was effective 20 May 2015, so implementers should refer to the 2015 consolidated part for current normative text.
Q: Is it part of a series?
A: Yes — it is one part of the IEC 62056 DLMS/COSEM series of standards covering application, transport and interface definitions for electricity metering data exchange.
Q: What are the key keywords?
A: COSEM, DLMS, transport layer, IPv4, UDP, TCP, meter reading, tariff, load control, IEC 62056.
