This part of IEC 62056 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. This first architecture completes the base protocol (IEC 61142) with remote transfer services while the second one allows operation of DLMS services using the same physical medium and the same physical layer. This complete compatibility guarantees the possibility of using IEC 61142 and IEC 62056-31 equipment on the same bus.
