Full title and description
Electricity metering - Data exchange for meter reading, tariff and load control - Part 31: Use of local area networks on twisted pair with carrier signalling. This International Standard specifies local bus architectures and protocol elements for data exchange on twisted-pair carrier-signalled networks used for meter reading, tariff and load-control functions.
Abstract
IEC 62056-31:1999 defines two architectures for local bus data exchange over twisted-pair carrier signalling (the Euridis-style bus): one for energized stations and one that supports non-energized stations supplied from the bus. The document details physical, data link and application-layer behaviours, supports remote reading and programming services, and describes how DLMS/COSEM services may be carried over the same physical medium to ensure interoperability with existing IEC protocols.

Scope
Specifies signalling and protocol profiles for local area networks over twisted pair using carrier signalling to support meter reading, tariff management and load control. The standard covers the physical interface and timing (including wake-up signalling for non-energized stations), data link management, application services for remote reading/programming and options to transport DLMS/COSEM services on the same physical medium to enable coexistence and interoperability with IEC 61142 and other IEC 62056 family elements.
Key topics and requirements
- Two local-bus architectures: for energized stations and for non-energized stations powered from the bus.
- Physical layer specification for twisted-pair carrier signalling (Euridis-style bus), including timing and wake-up procedures.
- Data link layer functions and state machines for primary/secondary station exchanges, half-duplex transaction management and error handling.
- Application-layer services supporting remote reading, remote programming, broadcast and point-to-point transfer.
- Compatibility provisions so IEC 61142-based equipment and DLMS/COSEM services can operate on the same bus.
Typical use and users
Used by electricity utilities, meter manufacturers, system integrators and testing laboratories involved in the design, deployment and maintenance of local meter-communication networks. It is primarily applicable where a twisted-pair carrier-signalling medium (Euridis bus) is selected for in-building or neighbourhood meter data collection and when support for non-energized (bus-powered) endpoints is required.
Related standards
Part of the IEC 62056 family (the DLMS/COSEM suite). IEC 62056-31:1999 replaced IEC 61142 (1993) functionality for these local-bus exchanges and was itself superseded by IEC 62056-3-1:2013, which extended profiles and incorporated DLMS/COSEM profiles; equivalent European adoption appeared as EN 62056-31:2000. Relevant related references include IEC 61142 and later IEC 62056-3-1 editions covering DLMS/COSEM on twisted pair.

FAQ
Q: What is this standard?
A: IEC 62056-31:1999 is an IEC International Standard that specified the use of twisted-pair carrier-signalled local-area buses for meter data exchange (meter reading, tariff and load control).
Q: What does it cover?
A: It covers the physical, data-link and application-layer definitions for two local-bus architectures (energized and bus-powered non-energized stations), wake-up signalling, transaction and error handling, and mechanisms to carry DLMS/COSEM services over the same medium for interoperability.
Q: Who typically uses it?
A: Utilities, meter manufacturers, integrators and conformity/test laboratories working on local meter communication networks and those implementing or maintaining Euridis-style twisted-pair carrier networks.
Q: Is it current or superseded?
A: Superseded. IEC 62056-31:1999 was withdrawn and replaced by IEC 62056-3-1:2013 (a technical revision that added DLMS/COSEM profiles and modernised link-layer/profile options). The formal withdrawal/replacement date is recorded in IEC publication information (withdrawal noted in 2013).
Q: Is it part of a series?
A: Yes — it belongs to the IEC 62056 family (DLMS/COSEM suite) and is related to earlier IEC 61142 material; later parts and revisions (for example IEC 62056-3-1) continue and expand the work begun in this part.
Q: What are the key keywords?
