电力公用事业自动化通信网络和系统 第 80-5 部分：IEC 61850 和 IEC 61158-15 之间映射信息指南

[中文适用范围]： 本部分为IEC 61850的技术报告，规定了通过利用IEC 61850和IEC 61158-6之间的网关，使用IEC 61850和IEC 61158-6（工业通信网络 - 现场总线规范，CPF类型15，Modbus）协议构建和配置系统的映射规则。目的是实现这些IED/子系统之间的运行时数据交换，并尽可能自动化网关的配置。 本文件主要关注电力公用事业行业，但其他提供能源和水的行业如果计划在其系统中同时使用Modbus和IEC 61850，也可以使用本文件。 [外文原描述]： IEC TR 61850-80-5:2024, which is a Technical Report, specifies the mapping rules for building and configuring a system using both IEC 61850 and IEC 61158-6 (Industrial communication networks - Fieldbus specification, CPF Type 15, Modbus) protocols by utilizing gateways between IEC 61850 and IEC 61158-6 IEDs / subsystems. The objective is to enable operational run-time data exchange among these IEDs / subsystems, and to automate the configuration of a gateway as much as possible. Please note that for the purposes of this document, "Modbus" is used to represent both serial Modbus (Modbus RTU) and IEC 61158-6 (Modbus TCP). Within the capability of each protocol, some configuration attributes (IEC 61850-7-3:2010+AMD1:2020 attributes with functional constraint CF) are also mapped in addition to the operational real-time data. The rules specified in this document are based on the published standards and do not make any proposed changes to IEC 61850 or 61158-6. This standard does not specify any rules for an IEC 61850 IED to directly communicate with a Modbus IED and vice versa, except through a gateway. This document does not mandate which data items that a particular IED shall support, regardless of whether the implementation uses Modbus or IEC 61850. Instead this document provides rules specifying how a gateway maps any given data item from one protocol to the other, given that the data item is already available and is transmitted using one of the protocols. Similarly, this document does not mandate which mapping rules a given gateway shall support. When this document is republished as a Technical Specification, conformance requirements will be identified. This document recognizes that there will be situations in which a user will require that a gateway perform non-standard protocol mappings. Non-standard mappings are outside the scope of this document. This document also recognizes that gateways typically manipulate the data passing through them in a variety of ways. Some of these functions include alarm trigger grouping, data suppression, interlocking and command blocking. Conformance to this document does not preclude a gateway from performing such functions, even though this document primarily specifies "straight through" mapping of Modbus data to IEC 61850-7-3:2010+AMD1:2020 data. Subclause 7.4 of this document describes how some of these functions may be specified to a gateway by a mapping tool using equation notation in XML. However, some of these functions may be too complex for a mapping tool to specify in an automated manner. The mapping architecture for the exchange of the run-time information consists of four parts: 1) Conceptual architecture of a gateway and associated use case 2) Mapping of the information model (Assign semantic to the Modbus data) 3) Mapping of the data (which is in fact part of the information model) 4) Mapping of the services (out of scope for this document)
