Industrial communication
AS-Interface
AS-Interface is the simple, low-cost, effective
networking system for the field level.
Data and energy are transferred over a single
cable. As an open manufacturer-independent
bus system, it transfers digital and
analog signals that are closely related to the
process and machine. On the other hand it
also functions as a universal interface
between simple binary actuators and sensors as well as to the higher
control levels – for standard and safety engineering. (for ASIsafe, also
refer to the Safety Integrated section)
Thanks to the AS-i master for interfacing to SIMATIC or the routers to
PROFIBUS or PROFINET, AS-Interface can be completely integrated in
TIA. All the diagnostic information of the AS-Interface network is then
available in the controller plant wide and can be read out, for example,
using Operator Panels or in the control room.

For further information about ASIsafe, refer to the chapter
Safety Integrated on page 97.
Connecting AS-Interface to the controller -
CPs for SIMATIC
Make your controller fit and ready for connection to AS-Interface
• Plug-in modules to AS-i Spec. 3.0 for
connection to the backplane bus of the
controller
• The controller becomes an AS-Interface
master and offers support for as many as
62 AS-Interface slaves (A/B system)
• Fast display of the slave states by means of
LEDs on the front panel
• Integrated analog value transmission
• No configuration necessary; optional for
S7-300: Upload the AS-i configuration into
STEP 7
Routers –

Further information about routers for AS-Interface can be found in this
chapter on page 132 et seq.
