The OBject Identification System (OBIS) defines the identification codes (ID-codes) for
commonly used data items in electricity metering equipment. This part of IEC 62056 specifies
the overall structure of the identification system and the mapping of all data items to their
identification codes.
OBIS provides a unique identifier for all data within the metering equipment, including not only
measurement values, but also abstract values used for configuration or obtaining information
about the behaviour of the metering equipment. The ID codes defined in this standard are
used for the identification of
? logical names of the various instances of the interface classes, or objects, as defined in
IEC 62056-62;
? data transmitted through communication lines, see Clause A.1;
? data displayed on the metering equipment, see Clause A.2.
This standard applies to all types of electricity metering equipment, such as fully integrated
meters, modular meters, tariff attachments, data concentrators, etc.
To cover metering equipment measuring energy types other than electricity, combined
metering equipment measuring more than one type of energy or metering equipment with
several physical measurement channels, the concepts of medium and channels are
introduced. This allows meter data originating from different sources to be identified. While
this standard fully defines the structure of the identification system for other media, the
mapping of non-electrical energy related data items to ID codes needs to be completed
separately.
NOTE EN 13757-1 defines identifiers for metering equipment other than electricity: heat cost allocators, cooling,
heating, gas, cold water and hot water.
