Overview
SIMATIC ET 200 distributed I/O
SIMATIC ET200 – offers the right solution for
every application
SIMATIC ET 200 offers a broad range of distributed
I/O systems - for solutions in the control cabinet or without a
control cabinet directly at the machine and for applications in
hazardous areas. Thanks to their modular design, ET 200
systems are easy to scale and expand in small steps. Ready
integrated add-on modules reduce costs while at the same time
offering extremely diverse application potential. A huge range of
different combinations can be selected: Digital and analog in-
puts/outputs, intelligent modules with CPU functionality, safety
engineering, motor starters, pneumatic systems, frequency con-
verters and a variety of technology modules, e.g. for counting
and positioning tasks.
The communication via PROFIBUS and PROFINET, the uniform
engineering, the user-friendly diagnostic tools and the optimum
interfacing with SIMATIC controllers and HMI equipment are all
proof of the unique consistency of the Totally Integrated Auto-
mation.
PROFIBUS
PROFIBUS is the international standard (IEC
1158/61784) for the
field level. It is the only fieldbus to allow communication both in
manufacturing applications and in process-oriented applica-
tions.
PROFIBUS is used to connect field devices such as distributed
I/O devices or drives to automation systems such as
SIMATIC S7, SIMOTION, SINUMERIK or PCs.
PROFIBUS is standardized in accordance with IEC 61158 and
is a powerful, open and rugged fieldbus system with short
response times. PROFIBUS is available in different forms for
various applications.

PROFIBUS DP (distributed I/O)
PROFIBUS DP is used for connecting distributed field devices,
e.g. SIMATIC ET 200 or drives, with extremely fast response
times. PROFIBUS DP is used when actuators/sensors are dis-
tributed at the machine or in the plant, e.g. at field level.
PROFINET
PROFINET is the open, cross-vendor Industrial Ethernet
standard (IEC 61158/61784) for automation.
Based on Industrial Ethernet, PROFINET enables direct commu-
nication between field devices (IO devices) and controllers
(IO controllers), up to and including the solution of isochronous
drive controls for motion control applications.
As PROFINET is based on Standard Ethernet according to
IEEE 802.3, any devices from the field level to the management
level can be connected.
In this way, PROFINET enables system-wide communication,
supports plant-wide engineering and applies IT standards, such
as Webserver or FTP, right down to field level. Tried and tested
fieldbus systems, such as PROFIBUS or AS-Interface, can be
easily integrated without any modification to the existing de-
vices.
