PRODUCT OVERVIEW
Master as a compact control for
SIMATIC S7
The SIMATIC C7 621 AS-Interface
unites in one complete housing the AS-
Interface master CP 342-2, a SIMATIC
CPU of the S7-300 class, and an OP3
operator panel. That makes it ideal for
quick and simple automation tasks that
do not require the performance of a hu-
man-machine interface. The addressing
and diagnostics of up to 31 slaves with
up to 124 inputs and outputs (no inte-
grated inputs and outputs) can be ac-
cessed and controlled directly from the
compact control. No additional address-
ing unit is required.
CP 142-2
An AS-Interface master is available for
the distributed I/O system for
PROFIBUS networks ET 200X, too. The
CP 142-2 communication processor is
connected to the ET 200X module via a
12-way connector and uses its standard
I/O range. No configuring is required for
the AS-Interface network. Up to 31
slaves can be addressed by the CP 142-
2 (124 inputs and outputs).
