The Actuator-Sensor Interface, called AS-lnterface® for short, is a system with which simple, binary and analog terminals sensors, actuators and control units can be networked via a cable on the lowest field level with the first control level.
AS-lnterface® is not a conventional field bus, but instead is to be seen as an intelligent wiring, which was designed as a universal and open system to provide a manufacturerindependent solution on the lowest field level. Consequently, it handles an area, which can only be reached with difficulty or not at all.
