ActiveProgrammable controllers—Part 9: Single-drop digital communication interface for small sensors and actuators (SDCI)
可编程序控制器 第9部分：用于小型传感器和执行器的单点数字通信接口(SDCI)
Application Summary AI generated
This standard specifies the physical layer, data link layer, and application protocol for a single-drop digital communication interface (SDCI) used to connect small sensors and actuators to programmable controllers. It is applied in industrial automation and manufacturing environments where compact, cost-effective, and deterministic point-to-point communication is required between a controller and low-power field devices. The standard ensures interoperability and reliable data exchange in applications such as assembly lines, packaging machinery, and process control systems.
