10.1 as-interface connection
AS-Interface (Actuator Sensor Interface) is a field bus system which is used primarily for networking binary sensors
and actuators (slaves) with a higher-level control (master).
Bus line
Unshielded two-wire line (AS-Interface line as AS-Interface cable harness) along which both information (data) and
energy (supply voltage for the actuators and sensors) are transmitted.
network topology
Freely selectable within wide limits, i.e. star, tree and line networks are possible. Further details describe the AS-
Interface specification (A/B slave model conforms to the version 3.0 specification).
