AS-i, short for Actuator Sensor Interface, is an industrial network system that was developed for the simple and cost-effective connection of sensors and actuators at the lowest automation level. It enables fast and efficient communication between simple field devices and higher-level control systems without the need for complex cabling.
AS-i is typically used in manufacturing and process automation and helps to reduce installation costs and times. The system is characterized by its flexibility and easy expandability, as new components can be added or removed without disrupting ongoing operations.
