IEC 62026的本部分规定了单个控制装置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系统。整个系统称为“执行器-传感器接口（AS-i）”。 本标准描述了一种连接开关元件（如IEC 60947中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装置和元件。交叉引用:IEC 61800-2IEC 60947-1:2007/AMD1:2010EN 60947-5-2:2007/A1:2012IEC 60204-1:2016EN 60947-4-2:2012IEC 60947-1:2007EN 60529:1991/A2:2013HD 60364-4-41:2007/A11:2017EN 60947-1:2007/A1:2011IEC 60947-5-2:2007/AMD1:2012HD 60364-4-41:2017EN 60947-2-2-2-2:2007EN 60947-2:2007EN 60729:1991/2007EN 60826-2007EN 60646:2006- 4-1:2018IEC 60947-4-2:2011EN 60068-2-27:2009EN 60204-1:2018IEC 60947-5-2:2007EN 60529:1991EN 60947-1:2007IEC 60068-2-6IEC 60068-2-27IEC 60529IEC 61131-2IEC 60364-4-41IEC 61140BS EN 62026-2:2013，其仍然有效，包括以下内容:修订，2020年1月

This part of IEC 62026 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 standard describes a method for connecting switching elements, such as low-voltage switchgear and controlgear, standardized within IEC 60947, and controlling devices. The method may also be applied for connecting other devices and elements.Cross References:IEC 61800-2IEC 60947-1:2007/AMD1:2010EN 60947-5-2:2007/A1:2012IEC 60204-1:2016EN 60947-4-2:2012IEC 60947-1:2007EN 60529:1991/A2:2013HD 60364-4-41:2007/A11:2017EN 60947-1:2007/A1:2011IEC 60947-5-2:2007/AMD1:2012HD 60364-4-41:2017EN 60947-5-2:2007EN 60529:1991/A1:2000EN 60068-2-6:2008IEC 60947-4-1:2018IEC 60947-4-2:2011EN 60068-2-27:2009EN 60204-1:2018IEC 60947-5-2:2007EN 60529:1991EN 60947-1:2007IEC 60068-2-6IEC 60068-2-27IEC 60529IEC 61131-2IEC 60364-4-41IEC 61140Replaces BS EN 62026-2:2013 which remains currentIncorporates the following:Amendment, January 2020
