Electricity metering data exchange - The DLMS/COSEM suite - Part 8-8: Communication profile for ISO/IEC 14908 series networks

IEC 62056-8-8:2020 describes how the DLMS/COSEM Application layer and the COSEM object model, as specified in IEC 62056‑5‑3:2017, IEC 62056‑6‑1:2017 and IEC 62056‑6‑2:2017, can be used over the lower layers specified in the IEC 14908 series, forming a DLMS/COSEM ISO/IEC 14908 communication profile. This document is part of the IEC 62056 series. Its structure follows IEC 62056-1-0 and IEC TS 62056-1-1.
