Systemdescription
5.3 AS interface
5.3.1 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 (power supply
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 are described in the AS interface specification
(A/B slave model conforms to the version 3.0 specification).
