International standards for electricity metering
For electricity metering, IEC TC13 WG14 has established the IEC 62056 series of standards: Electricity metering - Data exchange for meter reading, tariff and load control.
- IEC 62056-42: Physical layer services and procedures for connection-oriented asynchronous data exchange
- IEC 62056-46: Data link layer using HDLC protocol
- IEC 62056-47: COSEM transport layers for IPv4 networks
- IEC 62056-53: COSEM Application layer
- IEC 62056-61: Object identification system (OBIS)
- IEC 62056-62: Interface classes
In addition IEC 62056-21: Direct local data exchange (3d edition of IEC 61107) describes how to use COSEM over a local port (optical or current loop)
The standards can be purchased from the National Committees of the IEC or from the IEC Webstore directly.
