AS Interface - Design

11. AS INTERFACE - DESIGN

Deﬁnition11.1.

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).

Connecting the control heads to higher bus systems is possible using commercially available gateways.

Contact your distribution partner in this regard.

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).

Technical Data of the AS Interface of the Control Head:

See chapter 6. Technical Data

The control heads have been conﬁgured as AS interface version with an extended address range (A/B slaves)

for 62 slaves or optionally as an AS interface version for 31 slaves. For details, see chapter 11.8. Programming
