Industrial Communication for Automation and Drives - Induteq

AS-interface is a single-master system.
Communications processors (CPs) are
available for SIMATIC families which serve
as master for controlling processor or
field communication.
Extended AS-Interface Specification V2.1
permits interfacing of up to 62 slaves.
Thanks to the integration of analog-value
processing in the masters, accessing
analog values is just as easy as accessing
digital values. A DP/AS-Interface Link is
used to interface the SIMATIC S7-400 ®
to the AS-i network. DP/AS-Interface Link
20E in IP20 is available for connecting
the AS-Interface network directly to
PROFIBUS DP, making it possible to use
AS-i as PROFIBUS DP subnetwork.
This is how you save costs
AS-Interface replaces high-overhead
cable harnesses and connects binary
actuators and sensors such as proximity
switches, valves and indicator lights to a
programmable controller, for example
SIMATIC. In practice, this means problemfree
installation, since data and power
are transported over a single cable.
Thanks to a specially developed cable
and cable-piercing technology, the
AS-Interface cable can be tapped at any
point. This concept gives you enormous
flexibility and is exceptionally cost-saving.
Special knowledge of installation and
commissioning are unnecessary. In
addition, easy cable installation, a clear
cable structure and the special design of
the AS-i cable not only greatly reduce the
risk of errors, but also the overhead for
service and maintenance.
