SIMATIC ET 200pro 37
Interface module CPU module
for PROFINET
The interface module (IM) for PROFINET contains a 2-port
switch for easy configuration of a line structure. There is an
M12 connection for PROFINET and a 7/8" connection for the
power supply. More parameters are possible per station using
PROFINET, and therefore more high-function modules can be
used. When servicing, the IM can be replaced without using a
programming device – the device name and parameters are
saved on the the module.
With the interface module IM 154-4 PN HF, the interface mo-
dule and terminal module are separated as with the PROFIBUS
variant so that different connection methods are available.
The interface module offers both the tried and tested M12 7/8"
terminal and the possibility of a push-pull connection. The
integrated switch permits the easy setup of line structures.
The following connection modules are available:
CPU module
The interface module
IM154-8 CPU with CPU
functionality is based on
the CPU 315-2 PN/DP and
offers the same quantita-
tive framework and func-
tions. The IM154-8 CPU
has two communication
interfaces,
■ a combined MPI/PROFI-
BUS DP interface and
■ a PROFINET interface with three ports.
The IM 154-8 CPU supports both PROFINET IO (up to 128 IO
devices can be connected) and PROFINET CBA, as well as
PROFIBUS DP (as a master for up to 124 slaves).
The IM 154-8 CPU is not only compatible with the S7-300 CPUs
with regard to programming, but it also features a high degree
of data retentivity (protection against voltage failure). A sepa-
rate LED indicates maintenance alarms. Thanks to the Micro
Memory Card, modules can be replaced without any prob-
lems. A firmware update can be installed over the network.
Web-server functionality is also available for information, sta-
tus, diagnostics and time-synchronization over Ethernet
(NTP). The open Ethernet communication (TCP/IP, UDP, ISO-
on-TCP) offers fast and reliable exchange of data. Isochronous
mode is possible on PROFIBUS.
There is less loading on the central controller because individ-
ual plant sections can be configured, started up, diagnosed
and operated individually.
