标准摘要
[中文适用范围]： IEC 62056 的这一部分描述了两种新架构，用于与通电或未通电的站进行本地总线数据交换。对于未通电的站点，总线为数据交换提供能量。第一种架构通过远程传输服务完善了基本协议 (IEC 61142)，而第二种架构则允许使用相同的物理介质和相同的物理层来操作 DLMS 服务。这种完全兼容性保证了在同一总线上使用 IEC 61142 和 IEC 62056-31 设备的可能性。 [外文原描述]： 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 (IEC 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 IEC 61142 and IEC 62056-31 equipment on the same bus. This standard replaces IEC 61142 (1993). This publication is of high relevance for Smart Grid .
