Bit-modular distributed I/O system
Product Brief · March 2003

SIMATIC ET 200S the multi-functional, extremely
flexible distributed I/O system
SIMATIC® ET 200®S is a distributed I/O
system with degree of protection IP20.
It combines extremely simple installation
and maximum flexibility with
permanent savings in life-cycle costs.
Summary of features
· Bit-modular design for precise adaptation
to the automation task
· Independent wiring
· Wide range of modules:
- Input/output modules
- Process modules
-Motor starters
- Control functionality with CPU integration
· Various connection possibilities for
the terminal modules
· Reserve modules for reservation of
unused module slots
· Replaceable terminal box
· Use also possible for time-critical
tasks
· Integration of "Safety Integrated"
· Replacement of electronics modules
and motor starters during operation
(hot swapping)
· Simple diagnostics for exact channel
permits high availability: High-feature
or standard; system faults, for
example a missing supply voltage, are
automatically signalled as plain text
using the bus without programming
input.
Applications
· The comprehensive range of modules
with uniform handling for configuring,
installation and programming
mean that the ET 200S can be used as
a universal I/O system.
· The mechanical design of the ET 200S
permits use with increased mechanical
loading. The system properties
support high plant availability
requirements. The SIMATIC ET 200S is
therefore exceptionally suitable for
use with extremely time-critical applications.
Design
The bit-modular design permits fast and
optimum adaptation to the requirements
of any automation system:
· No stocking of spares
· No superfluous channels
The plant setting-up times can be significantly
reduced even with frequently
changing requirements by the replacement
or combination of various I/O
modules.
The ET 200S results in wiring savings of
up to 80% for the following reasons:
· All supply voltages are only
connected once, and automatically
connected to the next module when
mounting side by side.
· All motor starters are completely
prewired apart from the motor
connection (with a conventional
design, up to 15 connections must be
made.)

Terminal modules
Motor starters
· The power supply to the individual
motor starters is handled by a power
bus with a rating up to 50 A.
· All terminals have the characteristics
of terminal blocks - signal and motor
cables can therefore be directly
connected to the SIMATIC ET 200S
without intermediate terminals.
· Safety technology is also part of the
system - and thus also prewired as far
as possible.
The compact design, flush mounting
side by side, omission of various cable
ducts and the elimination of terminal
blocks mean that space savings are
guaranteed. This is also particularly
important when using motor starters.
With a completely distributed design
directly on the machine, only the power
supplies and host control systems are
usually required in the control room.
When comparing the ET 200S to established
solutions you can achieve up to
50% less space requirements in the
control cabinet and 80% saving in
wiring!

SIMATIC ET 200S
simple installation and wiring
Installation
It’s impossible to be simpler!
· Snap the interface module onto the
standard rail.
· The terminal modules can then be
fitted side by side without tools.
· The self-coding prevents destruction
of the electronics as a result of an I/O
module being inadvertently plugged
into the wrong position.

Strip-free Fast Connect system
The insulation displacement system
without the need for wire stripping
presents even more advantages when
installing. The TM-P and TM-E electronics
and power modules have been
extended by the Fast Connect insulation
displacement system without wire stripping.
All common conductor
cross-sections from 0.25 to 1.5 mm²
can be connected using the new
system. Preparation for installation is
unnecessary. In addition to the advantages
of the proven ET 200S system, the
new technology also enables:
· Time savings of up to 60% during
installation compared to conventional
connection systems
· No stripping or crimping necessary
· Simple and reliable installation using
a screwdriver
· Reduction in error rate during installation
· Definition of stripping length is
unnecessary
· Reliability with gas-tight connection

"Independent wiring"
The so-called independent wiring is a
specific characteristic of SIMATIC
ET 200S: the mechanical components
(terminal modules) are isolated from
the electronic components (electronics
modules, power modules, motor
starters). The independent wiring not
only facilitates design of the station, it
also has a positive effect on the availability
during operation:
· Complete prewiring is possible prior
to fitting the electronics modules and
motor starters - either using screw or
spring-mounted terminals as well as
the Fast Connect system without
stripping.
· The subsequent wiring test is even
possible under power because endangered
electronics components have
not yet been inserted.
· Thanks to the self-assembling power
buses, much of the cross-wiring
belongs to the past - this reduces test
requirements and possible sources of
error.
· The terminal modules have been
designed with the form and function
of a commercially available terminal
block. This guarantees simple, clear
wiring with acquainted handling.
· The module inscriptions are not
hidden by the wiring.
· The removable terminal box permits
simple connection of simulation
computers for preliminary commissioning.
Plug on finished!
Hot swapping for maximum availability
Hot swapping of electronics modules
and motor starters is possible without
tools. The SIMATIC ET 200S can
continue operation during swapping,
meaning that the application remains
fully functional in many cases.
With motor starters, it is even possible
to omit isolation of the system which is
usually obligatory.
Accessories
The ET 200S is well equipped for practice
with a versatile range of accessories:
· System-integrated shield connection
system with the following advantages:
- Low-impedance connection via
3 x 10 mm busbar
- Individual lengths
- Simple, fast installation with plug on
technology
- Space-saving
- Cost-effective as result of standard
components
· Individual colored labels for the
terminals on the terminal modules
and for identification of slot numbers;
available in various colors and also
individually packed.
· Identification labels for numbering
the terminal modules: pre-labelled or
blank.
· DIN A4 labelling sheets in various
colors, pre-perforated, suitable for
printing with laser printer

SIMATICT ET 200S
increased safety with fail-safe signal modules
The ET 200S provides you with the
capability to design economical solutions
for safety-oriented applications for
the production industry. It comprises a
fail-safe CPU S7-315F, corresponding
fail-safe I/O modules for the ET 200S
distributed I/O system, and special
drivers for interfacing field devices from
other vendors.
Fail-safe components
The following fail-safe CPUs are available:
CPU 315F of the S7-300®,
CPU 416F of the S7-400® and
IM 151-7F-CPU of the ET 200S.
Applications with the maximum safety
category 4 to EN954-1 can be implemented
in a simple manner using the
new fail-safe modules of the ET 200S
system and a SIMATIC F-CPU.
Safety signals, for example from light
barriers, EMERGENCY STOP buttons,
protective door switches etc., are
recorded on site by the distributed
fail-safe input module "4/8F-DI" of the
ET 200S system. The safety-oriented
data are then transmitted together with
the standard data to the host PLC via a
common PROFIBUS DP cable using the
PROFIsafe profile. A special bus cable,
or even an extra safety bus system, is no
longer necessary. "Safe" and "normal"
modules can be mixed together.
Advantages compared to conventional
safety systems
· Significant saving of components
(less hardware)
· Less assembly and installation work
· High flexibility
· When changes are necessary,
programming replaces wiring
· Implementable fail-safe and
fault-tolerant motor starters

ET 200S
Motor starters for every application
The ET 200S motor starters are used for
protecting and switching all kinds of AC
loads. The completely prewired devices
are available in a variety of performance
classes as direct, reversing or soft starters
up to a max. power of 7.5 kW. The
terminal modules contain the self-assembling
power bus (one-time infeed
for up to 20 motor starters) and the terminals
for direct connection of the motor
cable. A motor starter can be
plugged/unplugged without isolating
the plant.

Standard motor starter
· Circuit-breaker/contactor combination
up to 5.5 kW
· Direct or reversing starter
· Self-assembling power bus up to 40 A
· SIGUARD safety technology optional
High-feature motor starter
· Combination of starter circuit-breaker,
electronic overload relay and
contactor or soft starter up to 7.5 kW
· Extensive diagnostics messages, e.g.
momentary current value
· Statistics, e.g. current of the last overload,
can be read-out using the ES
motor starter service and startup software
switch
· Parameterization via bus
· Only two current setting ranges up to
7.5 kW
Graded safety concept
The motor starters of the ET 200S offer
a graded safety concept. Depending on
application it is possible to select the
optimum solution on a function/cost basis
to suit each case in hand.
ET 200S SIGUARD
ET 200S SIGUARD saves a lot on wiring
on the basis of conventional safety relays
in less complex local safety applications.
Power modules for Emergency-Stop
or safety door applications are
available just like modules for time delay
and contact multiplication.
The safety sensors are connected directly
on these local modules.
Function monitoring, e.g. for cross connection,
is implemented just like the
monitoring of the switching function of
the motor starters in the ET 200S
SIGUARD modules. ET 200S SIGUARD
modules automatically signal operating
and error states via PROFIBUS diagnostics
to the higher-level controller.
Cascading of safety segments within an
ET 200S station is possible by corresponding
combination of SIGUARD modules
or their terminal modules.
For Category 3 or 4, external redundancy
contactors are looped into the power
infeed of the power bus. These contactors
are also controlled and monitored
by the SIGUARD modules.
Fail-safe motor starter
As soon as more complex or physically
remote safety applications are involved,
the fail-safe motor starter is the optimum
solution in combination with the
power module PM-D F PROFIsafe. Signals
from safe sensors are read in via
safe inputs at a random location in the
plant, transmitted via PROFIBUS and the
PROFIsafe message frame to the failsafe
controller and linked there in the user
program to the fail-safe motor starter or
the associated power module.
These motor starters based on the
high-feature motor starter offer a completely
new and patented technology
for safety disconnection: whereas in
normal operation the contactor
performs disconnection, the integrated
double processor monitor also switches
off the circuit breaker in the event of a
fault, e.g. welded contactor contacts.
Each individual motor starter thus
achieves Category 4 or SIL 3 without an
additional redundancy contactor.
Since the fail-safe motor starters monitor
the contactor function regardless of
whether the application is safety-relevant
or not, these devices are also suitable
for use in fault-tolerant processes.
Additional features for high availability
are:
· Type of coordination 2 over the entire
power range up to 7.5 kW
· Emergency Stop function permits important
processes to be finished despite
reason to switch off, e.g.
overload.
Advantages in comparision to conventional
safety technology:
· Considerably fewer components,
clearer design and much less hardware
configuring and wiring
· Easy installation thanks to simple connection
· Motor starters have a high availability
and are fail-safe
· High flexibility through software-oriented
assignment of the safety
groups
· Minimum overhead when modifying
the safety application, since the
wiring remains the same

SIMATIC ET 200S
increased functionality with CPUs, IQ Sense
and power supply
Distributed intelligence -
intelligent CPU of the ET 200S
The IM 151-7 CPU can be used for
distributed automation solutions with a
medium program size. It permits distributed
preprocessing of production data
on site.
The CPU communicates with the host
controller via the coexistent
MPI/PROFIBUS DP slave interface. This
results in the following advantages:
· Reduced loading on central controller
· Reduced response times to critical
local signals
· Programs become clearer and shorter
· Troubleshooting is facilitated
· Reduces loading on bus system
· Permits modular plant design and
preliminary commissioning - even at
different locations
Using the new DP master module it is
possible to add an integrated DP master
interface to the IM 151-7 CPU and thus
implement an underlying PROFIBUS
line with additional distributed I/Os.
All this does not require additional software
handling, since SIMATIC ET 200S
can be configured, programmed and
diagnosed on the PROFIBUS from any
position using STEP 7. The STEP 7 Lite
programming tool is available for
non-networked applications.
Status/control functions are also
possible via the PROFIBUS. Thanks to
the plug-in SIMATIC Micro Memory
Card, the application program is immediately
available again following
module replacement. Thus SIMATIC
ET 200S with IM 151-7 CPU can be used
as a bit-modular small control system.
IM 151-7 CPU interface module with integral
CPU (also available as an F-version) and
master module
Intelligent sensor module -
IQ Sense®
The four-channel IQ Sense® sensor
module together with the new
IQ Sense sensors provides a new
concept for intelligent linking of sensor
technology into automation technology.
The ET 200S provides all functions
for any PROFIBUS DP master
modules.
Standard function blocks are offered for
simple handling on a SIMATIC S7.
Up to four sensors can be connected
with just two lines each, and parameterized
using the Intelliteach® function.
Main applications are plants and
machines
· with high availability demands,
· with high probability of mutual influencing
of sensors
· with high flexibility or dynamic modifications
for the sensor parameters

Power supply
A highly compact power supply measuring
a mere 90 mm wide is available for
the ET 200S. The ET 200S power supply
permits 2-phase connection of 240 or
400 V AC.
The stabilized output voltage of 24 V DC
can supply a maximum of 5A continuous
current and is stable at no load
and is short-circuit resistant. With a high
efficiency of over 92% the ET 200S
power supply ensures efficient power
conversion and a cool switchbox. The
power supply can be set to standby
mode and the output side thus switched
to voltage-free. Three LEDs
provide users at all times with clear
information on the present operating
status.
6
A plug-in terminal is used for the wiring,
which means that if the worst comes to
the worst the power supply can be
changed quickly and reliably without
rewiring. Due to its compact size the
power supply can also be used in distributed
applications independently of the
ET 200S.
