Electricity metering data exchange - The DLMS/COSEM suite - Part 8-4: Communication profiles for narrow-band OFDM PLC PRIME neighbourhood networks
电能计量数据交换.DLMS/COSEM套件.第8-4部分:窄带正交频分复用可编程逻辑控制器主邻域网络的通信轮廓
IEC 62056-8-4:2018 specifies DLMS/COSEM communication profiles for narrow-band OFDM power line carrier PRIME neighbourhood networks using the modulation as specified in Recommendation ITU-T G.9904:2012.
Three communication profiles are specified:
?a profile using the IEC 61334-4-32 LLC layer;
?a profile using TCP-UDP/IPv4;
?a profile using TCP-UDP/IPv6.
