UNE-EN 62056-6-1:2017

This part of IEC 62056 specifies the overall structure of the OBject Identification System(OBIS) and the mapping of all commonly used data items in metering equipment to theiridentification codes.OBIS provides a unique identifier for all data within the metering equipment, including not onlymeasurement values, but also abstract values used for configuration or obtaining informationabout the behaviour of the metering equipment. The ID codes defined in this standard areused for the identification of:" logical names of the various instances of the ICs, or objects, as defined in IEC 62056-6-2;" data transmitted through communication lines;" data displayed on the metering equipment, see Clause A.2.This standard applies to all types of metering equipment, such as fully integrated meters,modular meters, tariff attachments, data concentrators, etc.To cover metering equipment measuring energy types other than electricity, combinedmetering equipment measuring more than one type of energy or metering equipment withseveral physical measurement channels, the concepts of medium and channels areintroduced. This allows meter data originating from different sources to be identified. Whilethis standard fully defines the structure of the identification system for other media, themapping of non-electrical energy related data items to ID codes needs to be completedseparately.NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators, thermal energy,gas, cold water and hot water.
