Introduction

At present, energy saving, emission reduction, low carbon, environmental protection and the establishment of a sustainable society have become a global consensus: Countries actively build regional capacity

Energy management system to promote efficient and scientific utilization of energy: On this basis, IEC /TC57, TC13 and EN/TC294 jointly established

The transmission protocol of DLMS/COSEM energy measurement system is proposed, in which the electric energy part is completed by IEC 62056, and the non-electricity part is completed by IEC 62056:

EN13757 to complete: Countries around the world have successively converted IEC 62056 into their own national standards: To establish a globally unified, open interoperability

In my country, IEC 62056-XY is equivalently converted into GB/T 17215:6XY:

This document specifies the DLMS/COSEM transport layer based on IP (IPv4 or IPv6) networks, and should be read in conjunction with GB/T 17215:697-

2018:

The IEC 62056 DLMS/COSEM component standard has been developed by IEC /TC13 for electrical measurement purposes: some standards

(especially the COSEM data model) has also been used by other non-coulometric technical committees:

Electrical measurement data exchange DLMS/COSEM components

Part 47: DLMS/COSEM over IP networks

transport layer

1 Scope

This document specifies the transport layer of the DLMS/COSEM communication protocol suite used in IP networks for connectionless and connection

(TL):

These transport layers provide OSI-style services to the application layer of the user DLMS/COSEM: The connectionless oriented transport layer is based on the Internet

Standard User Datagram Protocol (UDP): The connection-oriented transport layer is based on the Internet standard Transmission Control Protocol (TCP):

The main part of the DLMS/COSEM transport layer is UDP and TCP, and the TCP and additional sublayers are called encapsulation sublayers:

Appendix A illustrates how OSI-style transport layer services translate between UDP and TCP function calls:
