OBIS-Code Configuration
Object identification system (OBIS) Codes are used to identify the different readings of a smart meter transferred in Smart Message Language (SML), which is a commonly used protocol on D0 optoelectronic interfaces. 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 und 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
| Obis Code | Meaning |
|---|---|
| 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] |
