标准摘要
[中文适用范围]： IEC 62026-2:2008+A1:2019规定了单个控制设备和开关元件之间的通信方法，并建立了具有指定通信接口的组件互操作性的系统。完整的系统称为“执行器传感器接口（AS-i）”。 IEC 62026-2 第二版取消并取代了 2000 年发布的第一版。它构成了技术修订。相对于前一版本的主要变化如下： - 通过引入子地址，从站数量从 31 个增加到 62 个； - 引入 AS-I 安全系统。该合并版本由第二版（2008年）及其修正案1（2019年）组成。因此，无需对本出版物进行修订。 [外文原描述]： IEC 62026-2:2008+A1:2019 specifies a method for communication between a single control device and switching elements, and establishes a system for the interoperability of components with the specified communication interfaces. The complete system is called "Actuator Sensor interface (AS-i)". This second edition of IEC 62026-2 cancels and replaces the first edition published in 2000. It constitutes a technical revision. The main changes with respect to the previous edition are listed below: - doubling the number of slaves from 31 to 62 by introduction of sub-addresses; - introduction of AS-I safety system. This consolidated version consists of the second edition (2008) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
