标准摘要
[中文适用范围]： IEC 61162的这一部分是IEC 61162-450的附加标准，适用于需要更高安全和安全标准的场景，例如由于外部威胁增加或需要提高网络完整性。本文档提供了用于符合IEC 61162-460标准的网络设备的要求和测试方法，以及网络本身的要求和与其他网络互连的要求。本文档还包含冗余IEC 61162-460兼容网络的要求。本文档未引入新的应用层协议要求，这些要求已在IEC 61162-450中定义。 [外文原描述]： IEC 61162-460:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61162-460:2024 edition 3.0 and the previous IEC 61162-460:2018+AMD1:2020 CSV edition 2.1. Furthermore, comments from IEC TC 80 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 61162-460:2024 is an add-on to IEC 61162-450 where higher safety and security standards are needed, for example due to higher exposure to external threats or to improve network integrity. This document provides requirements and test methods for equipment to be used in an IEC 61162-460 compliant network as well as requirements for the network itself and requirements for interconnection from the network to other networks. This document also contains requirements for a redundant IEC 61162-460 compliant network. This document does not introduce new application level protocol requirements to those that are defined in IEC 61162-450. The contents of the corrigendum of July 2024 have been included in this copy.
