概述
为了实施通信，以下组件
系统安装可用：
•
中央控制单元（例如Simatic S7）的AS-I模块，
ET 200M/ET 200SP distributed peripherals, or network
transitions from PROFIBUS or PROFINET to AS-Interface
•
Power supply unit, if required in combination with a data
decoupling module for the power supply to the slaves
•
AS-Interface shaped cables
•
网络组件，例如中继器和扩展插头
(不能用于我Power24V)
•
I/O modules (AS-i slaves) for connection of standard
传感器/执行器
•
Actuators and sensors with integrated AS-i slave
•
安全的I/O modules (ASIsafe slaves) for transmitting
通过As-Interface与安全有关的数据
•
Addressing device for setting slave addresses during
commissioning
