AS-Interface serves as a cost-effective system for the lower field level of automation. AS?Interface was specially developed to meet the demands of connecting binary sensors and actuators as well as interfacing to the higher control level. A straightforward, cost-effective installation with minimal connection costs was of paramount importance to the developers. The AS-Interface is often used in systems where numerous actuators and sensors, installed across a wide area, need to be networked cost effectively. Examples include conveyor and handling systems in airports, automated postal sorting, and the food and beverage industry.
