GB/T 18858.2-2012 in English

《GB/T 18858.2-2012低压开关设备和控制设备 控制器 设备接口（CDI） 第2部分:执行器传感器接口（AS-i）》由TC189（全国低压电器标准化技术委员会）归口，主管部门为中国电器工业协会。

Scope

This part of GB/T 18858 specifies a communication method between individual control equipment and switching elements, and establishes an interoperable system for components with specified communication interfaces. The complete system is called "Actuator Sensor Interface (AS-i)". This section describes the method of connecting switching elements, such as low-voltage switchgear and controlgear within the scope of GB 14048, and controlgear. This method can also be used to connect other electrical appliances and components. When input and output I/O are described within the scope of this standard, the meaning is for the master station, and the opposite is true for the application. The purpose of this standard is to specify the following requirements between control circuit devices and switching elements: - transmission system requirements, and interface requirements between slaves, masters and electromechanical equipment; - within the scope of this standard, in any network Requirements for complete interoperability of different electrical appliances; - Requirements for the interchangeability of equipment within the network described in this section; - Normal working conditions for slave stations, electromechanical equipment and master stations; - Structure and performance requirements; - Consistency verification.
