标准摘要
[中文适用范围]: 本国际标准规定了核电厂执行 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。该标准的范围仅限于考虑工厂 IC 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标准的范围。本标准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。该标准参考了在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 60780 和 IEC 60980 的抗震资格(即@需要安全功能运行的环境) [外文原描述]: IEC 61500:2009 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 second edition is intended to accomplish the following: - to change the focus from multiplexed data transmission to data communication; - to restrict the scope to communication in systems performing category A functions.
