Component Function
Distributed I/O systems
SIMATIC ET 200M Modular I/O system for control cabinet installation and high channel
density
SIMATIC ET 200S Finely modular I/O system for control cabinet installation including
motor starters, safety technology, and individual grouping of the load
groups
SIMATIC ET 200pro Modular I/O system with IP65/66/67 degree of protection for cabinet-
free use close to the machine; with new features such as small
frame size, integrated PROFIsafe safety technology, PROFINET
connection and hot swapping of modules.
SIMATIC ET 200eco I/O system with IP 67 degree of protection for cabinet-free use close
to the machine with flexible and fast ECOFAST or M12 connection
methods
Gateways
• DP/AS-Interface link 20E and DP/AS-Interface link Advanced for
the PROFIBUS DP gateway to AS-Interface
• DP/DP coupler for connecting two PROFIBUS DP networks
Drive interfaces
• ADI4 (Analog Drive Interface for 4 axes) for connection of drives
with analog ± 10 V setpoint interface or for external encoders
• IM174 (Interface Module for 4 axes) for connection of drives with
analog ± 10 V setpoint interface, for external sensors, or for
connection of stepper drives with pulse-direction interface
Drive units with
PROFIBUS DP interface (e.g.,
SINAMICS S120)
... convert speed setpoints into signals for controlling the motor and
supply the power required to operate the motors.
Also can be operated as an isochronous slave on PROFIBUS DP.
Ethernet
The control unit can communicate with the following components via the Ethernet interfaces
or be embedded in an automation environment:

Programming device (PG/PC) ... configures, parameterizes, programs, and tests with the
"SIMOTION SCOUT" engineering system (ES)
SIMATIC HMI device ... is used for operating and monitoring functions. This is not an
essential requirement for the operation of a control unit.
Master computer ... communicates with other devices via UDP, TCP/IP
