电能计量数据交换DLMS/COSEM套件第3-1部分:带载波信令的双绞线局域网的使用

[中文适用范围]： 本部分IEC 62056描述了两种配置文件的三个配置文件：第一组配置文件允许客户端和服务器之间的双向通信。这组配置文件由三个配置文件组成，允许本地总线数据交换，无论站点是否通电。对于未通电的站点，总线提供能量进行数据交换。支持三种不同的配置文件： - 基本配置文件：这个三层配置文件提供远程通信服务； - 带DLMS的配置文件：该配置文件允许使用IEC 61334-4-41中规定的DLMS服务； - 带DLMS/COSEM的配置文件：该配置文件允许使用IEC 62056-5-3和IEC 62056-6-2中分别规定的DLMS/COSEM应用层和COSEM对象模型。 这三个配置文件使用相同的物理层并且完全兼容，意味着实现这些配置文件的设备可以在同一总线上运行。传输介质是使用载波信号的双绞线，称为Euridis总线。 第二组配置文件允许在给定的电能计量设备和客户能源管理系统之间进行单向通信。这第二组由三个配置文件组成。 第4.2.1条至第8条规定了使用双绞线信号的双向通信，第9条至9.5条规定了使用双绞线信号的单向通信。 [外文原描述]： IEC 62056-3-1:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62056-3-1:2021 describes two sets of profiles: the first set of profiles allows a bidirectional communication between a client and a server. This set of profiles is made of three profiles allowing local bus data exchange with stations either energized or not. For non-energized stations, the bus supplies energy for data exchange. Three different profiles are supported: • base profile: this three-layer profile provides remote communication services; NOTE 1 This first profile was published in IEC 61142:1993 and became known as the Euridis standard. • profile with DLMS: this profile allows using DLMS services as specified in IEC 61334 4 41; NOTE 2 This second profile was published in IEC 62056-31:1999. • profile with DLMS/COSEM: this profile allows using the DLMS/COSEM Application layer and the COSEM object model as specified in IEC 62056 5 3 and in IEC 62056 6 2 respectively. The three profiles use the same physical layer and they are fully compatible, meaning that devices implementing any of these profiles can be operated on the same bus. The transmission medium is twisted pair using carrier signalling and it is known as the Euridis Bus. The second set of profiles allows unidirectional communication between a given Energy Metering device and a Customer Energy Management System. This second set is made up of three profiles. Subclause 4.2.1 to Clause 8 included specify the bidirectional communication using twisted pair signalling and Clause 9 to 9.5 the unidirectional communication using twisted pair signalling. This second edition cancels and replaces the first edition of IEC 62056-3-1, issued in 2013, and constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: • addition of a profile which makes use of the IEC 62056 DLMS/COSEM Application layer and COSEM object model; • review of the data link layer which is split into two parts: – a pure Data Link layer; – a "Support Manager" entity managing the communication media; • ability to negotiate the communication speed, bringing baud rate up to 9 600 bauds.
