标准摘要
[中文适用范围]： 本文件规定了核电厂执行 A 类功能的系统中使用的数据通信的要求。它还涵盖执行 A 类功能的设备与其他系统（包括执行 B 类和 C 类功能以及对安全不重要的功能的系统）的数据通信的接口要求。本文件的范围仅限于考虑工厂 IC 安全系统内的数据通信。不包括电话@无线电@语音@传真@电子邮件@公共地址@等方式的通信。数据通信设备的内部操作和详细技术规范不属于本文件的范围。本文件不适用于处理器单元@其存储器和控制逻辑的内部连接和数据通信。它不涉及仪器仪表和控制计算机系统的内部处理。本文件参考了在IEC 61513框架内制定的IEC 60880和IEC 60987@，给出了在线工厂数据通信的功能和属性要求。它要求根据IEC 61226@对通信功能进行分类，而IEC 61226@又要求环境符合 IEC/IEEE 60780-323 和 IEC 60980 的抗震资格（即安全功能需要运行的环境）。 [外文原描述]： IEC 61500:2018 establishes requirements for data communication which is used in systems performing category A functions in nuclear power plants. It covers also interface requirements for data communication of equipment performing category A functions with other systems including those performing category B and C functions and functions not important to safety. This document gives requirements for functions and properties of on-line plant data communication by reference to IEC 60880 and IEC 60987, produced within the framework of IEC 61513. It requires categorisation of the communication functions in accordance with IEC 61226. This new edition includes the following significant technical changes with respect to the previous edition: - the changes introduced to previously referenced standards have been confirmed to apply; - relevant newly published standards have been referenced; - lessons learned from several industrial applications have been incorporated.
英文名称Nuclear power plants - Instrumentation and control systems important to safety - Data communication in systems performing category A functions
