SIMATIC ET 200S 25
Distributed intelligence
The interface modules with
integrated CPU can be used
both in stand-alone mode
and for distributed automa-
tion solutions with a medi-
um-sized program. They
correspond to a CPU 314
and enable distributed
preprocessing of the pro-
duction data locally – even
in the failsafe version.
Depending on the version,
communication can take place via MPI/PROFIBUS and/or
PROFINET. This has the following advantages:
• Relieves the central control unit
• Reduction in the response times to critical local signals
• More transparent and shorter programs
• Easier trouble-shooting
• Less load on the bus system
• Modularization of the system structure and precommis-
sioning – also at different sites
Additional PROFIBUS line
The DP master module for
the interface module with in-
tegrated CPU is used to ex-
pand the ET 200S as master
with an integrated DP master
interface.
A lower-level PROFIBUS line
can then be configured with
further distributed I/O.
Options handling
With the use of options handling with SIMATIC ET 200S, the
entire station including all options is configured. Modules for
unnecessary options are either replaced by reserve modules
or can be completely eliminated. Optional functions are acti-
vated during operation without new configuration.
Options handling is available in two versions:
With reserve modules
In this case, the station is configured with all options. I/O mod-
ules that are not required are replaced by cost-effective re-
serve modules. Later, they can be exchanged for the config-
ured modules without new configuration, even during ongo-
ing operation.
Without reserve modules
In this case, the station is configured with all options, howev-
er, only the necessary modules (terminal and I/O modules) are
plugged in. The modules which are not plugged in can be later
retrofitted as required without new configuration.
Options handling is available for interface modules with PRO-
FINET interface and for those with PROFIBUS interface.
SIMATIC ET 200S COMPACT –
The block I/O featuring bit-modular expansion
SIMATIC ET 200S COMPACT is
the new interface for the bit-
modular ET 200S I/O system.
The new IM 151-1 COMPACT
interface module expands
the well-known range of
proven ET 200S modules and
permits use as a block I/O.
The functionality is based on
the IM 151-1 BASIC and
comprises an interface mod-
ule and 32 channels in one
block. Two different variants of the ET 200S COMPACT are of-
fered – either a station with 32 digital inputs or mixed with 16
digital inputs and 16 digital outputs.
By expanding the block with ET 200S modules (up to 12 mod-
ules), a total of 128 channels can be connected to the SIMATIC
ET 200S COMPACT. This means that frequently required in-
puts/outputs in block form can be combined with bit-modular
specialist modules such as motor starters, pneumatics, etc.
Expansions with the
8-channel modules support
an extremely high
packing density. As a result,
one terminal box can accom-
modate more components or
a smaller terminal box can be
used.
