SIMATIC ET 200M
The S7-300 I/O with high channel density
The ET 200M distributed I/O system is modularly designed
with IP20 degree of protection. Up to 12 multi-channel sig-
nal modules (e.g. 64 digital inputs) and function modules
as well as S7-300 communications processors can be used
as I/O modules – the interface to the process.
There are no slot rules. Hot swapping and expansion of mod-
ules is permissible when using active bus modules.
Connection to PROFINET and PROFIBUS is made via interface
modules.
In addition to screw-type and spring-loaded terminals, con-
nection of the signals can be made even simpler and faster us-
ing SIMATIC TOP connect. Preassembled front connectors with
single conductors and a complete plug-in modular system are
available. FastConnect plugs do not require the cables to be
stripped. The cable is simply plugged in and the contact is
made using the insulation displacement method.
The PROFINET version of the ET 200M offers new functions,
e.g.:
• Shared device
• Media redundancy protocol (MRP)
When the ET 200M is operated with an S7-400H/FH on
PROFIBUS, the availability of the plant can be increased:
• Switched connection:
One ET 200M with two interface modules
• Redundant connection:
Two ET 200M with one interface module each
When the ET 200M is connected to PROFIBUS on an S7-400,
the controller can be configured during normal operation
(Configuration in RUN - CiR).
In this manner,
• complete ET 200M I/O stations can be added,
• individual modules can be added within a station, and
• individual digital and analog module parameters can be
modified.
Hot swapping of signal modules is possible, thus reducing
downtimes. Failsafe I/O modules permit the integration in
safety-related plants with SIMATIC Safety Integrated.
SIPLUS components also enable operation in the extended
temperature range -40 °C ... +70 °C and in corrosive atmo-
spheres or under condensation conditions
(for details, see: www.siemens.com/siplus-extreme).

FastConnect
The insulation displace-
ment method Fast Connect
offers even more benefits
when wiring the I/O
modules:
• Available as 20-pole and
40-pole variants
•Suitable for all S7-300
I/O modules
• Permissible core cross-
sections: 0.5 … 1.5 mm²
• Suitable for rigid and
flexible conductors
• Opening for test tip with
a diameter of up to
1.5 mm
• Time savings of up to
60% for installation as compared to conventional connec-
tion methods
• No stripping or crimping necessary
• Easy, secure installation with a screwdriver
• Reduction in the number of installation errors
• The stripped length does not have to be determined
