OBIS-Codes

Object identification system (OBIS) Codes are used to identify the different readings of a smart meter transferred in Smart Message Language (SML). They are described in the international standard IEC 62056-61.

Structure

Every code consists of 6 separated group sub-identifiers. In general some of these identifiers may be omitted but our products require the full code. The basic pattern is:

A-B:C.D.E*F

groupdescriptionexamples
Amedium1 = electricity, 8 = water
Bchannel0 = no channel available
Cphysical unit, depends on Apower, current, voltage...
Dmeasurement type, depends on A and Cmaximum, current value, energy...
Etariff0 = total, 1 = tariff 1, 2 = tariff 2 ...
Fseparate values defined by A-Ebilling periods, 255 if not used


Examples




1-0:1.8.0*255Positive active energy (A+) total [kWh]
1-0:3.8.1*255Positive reactive energy (Q+) in tariff T1 [kvarh]
