Electricity metering - Data exchange for meter reading, tariff and load control - Part 31: Use of local area networks on twisted pair with carrier signalling
Describes two new architectures for local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. The first architecture completes the base protocol (EN 61142) with remote transfer services. The second architecture allows operation of DLMS services using the same physical medium and the same physical layer. This complete compatibility guarantees the possibility of using EN 61142 and IEC 62056-31 equipment on the same bus.
