Introduction
1.5 System components
Component Function
automation landscape by means of Ethernet
interfaces:
• Programming devices (PGs/PCs)
• SIMATIC HMI devices
• Other devices via UDP
Distributed I/O systems
The control unit can communicate via two PROFIBUS-DP interfaces with the following
distributed I/O systems:
Table 1-4 Distributed I/O systems
Distributed I/O Function
SIMATIC ET 200M Modular I/O system for control cabinet installation
and high channel density
SIMATIC ET 200S Highly modular I/O system for control cabinet
installation including motor starters, safety
technology, and individual grouping of the load
groups
SIMATIC ET 200X Modular I/O system with IP 65/67 degree of
protection for machine-related use outside a
control cabinet including motor starters and
pneumatic modules as well as DESINA and
ECOFAST-compliant modules
SIMATIC ET 200eco I/O system with IP 67 degree of protection for
machine-related use without a control cabinet
with flexible and fast ECOFAST or M12
connection methods
Drive units Also as an isochronous slave on PROFIBUS-DP
Other PROFIBUS I/O
ADI4 For the connection of drives with analog ±10 V
setpoint interface
Optional components
The following components enable an expansion of the functionality.
