DESCRIPTION
BS EN 62056-42:2002
This standard BS EN 62056-42:2002 Electricity metering. Data exchange for meter reading, tariff and load control is classified in these ICS categories:
29.120.50 Fuses and other overcurrent protection devices
91.140.50 Electricity supply systems
35.100.10 Physical layer
IEC 62056-42:2002 specifies the physical layer services and protocols within the Companion Specification for Energy Metering (COSEM) three-layer connection oriented profile for asynchronous data communication. 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. Annex B gives an explanation of the role of data models and protocols in electricity meter data exchange. This bilingual version (2013-05) corresponds to the monolingual English version, published in 2002-02.
