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:

1 Scope

This document specifies how COSEM clients use Web services to access DLMS/COSEM servers: Web services are

Inter-CAS (COSEM Access Service, COSEMAccessService) is provided: The DLMS/COSEM server contains an application server

The server supports the data model of IEC 62056-6-1 and IEC 62056-6-2 and the application layer of IEC 62056-5-3: This document does not cover

Covers the lower communication layer between the CAS and the DLMS/COSEM server: Rather, it is assumed that these communication configuration standards already exist, which

This standard describes how the underlying communication technology can be used to connect IEC 62056-6-1, IEC 62056-6-2 and IEC 62056-5-3:

The web services specified in this document refer to the G2 interface in the architecture defined in IEC 62056-1-0:

This document specifies CAC (COSEM Access Client, COSEM AccessClient) and CAS (COSEM Access Service,

COSEMAccessService), as shown in Figure 1:
