ÖVE/ÖNORM EN 62056-42

Issue date: 2003 04 01

Electricity metering - Data exchange for meter reading, tariff and load control - Part 42: Physical layer services and procedures for connection-oriented asynchronous data exchange (IEC 62056-42:2002)

This standard specifies the physical layer services and protocols within the Companion Specification for Energy Metering (COSEM) three-layer connection oriented profile for asynchronous data communication. The document does not specify physical layer signals and mechanical aspects. Local, implementation-specific issues are also not specified.In annex A, an example of how this physical layer can be used for data exchange through the Public Switched Telephone Network (PSTN) using intelligent Hayes modems is given. The use of the physical layer for the purposes of direct local data exchange using an optical port or a current loop physical interface is specified in IEC 62056-21. Annex B gives an explanation of the role of data models and protocols in electricity meter data exchange.

Frequently Asked Questions about ÖVE/ÖNORM EN 62056-42

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
