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
| group | description | examples |
|---|---|---|
| A | medium | 1 = electricity, 8 = water |
| B | channel | 0 = no channel available |
| C | physical unit, depends on A | power, current, voltage... |
| D | measurement type, depends on A and C | maximum, current value, energy... |
| E | tariff | 0 = total, 1 = tariff 1, 2 = tariff 2 ... |
| F | separate values defined by A-E | billing periods, 255 if not used |
Examples
1-0:1.8.0*255 | Positive active energy (A+) total [kWh] |
1-0:3.8.1*255 | Positive reactive energy (Q+) in tariff T1 [kvarh] |
