标准摘要
[中文适用范围]： IEC 62026 的这一部分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)”。本标准描述了连接开关元件（例如 IEC 60947 内标准化的低压开关设备和控制设备）和控制设备的方法。该方法也可用于连接其他设备和元件。本标准中描述的输入和输出 I/O 的含义与主机有关，与应用程序有关的含义则相反。 [外文原描述]： IEC 62026-2:2008 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.
