PROFIBUS DP   
The control unit can communicate with the following components via the PROFIBUS DP 
interfaces:
Table 2-3
Components on PROFIBUS DP
Component  Function
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
Other controllers (e.g. 
SIMOTION or SIMATIC)
... e.g. higher-level controller (plant controller); modular machine 
concepts with multiple controllers, distributed across individual 
machine modules.
Distributed I/O systems  
SIMATIC ET 200MP Modular I/O system for cabinet installation and high channel densities 
in the SIMATIC S7‑1500 packaging system. SIMATIC ET 200MP 
permits the shortest bus cycle times and fastest response time even 
with large volumes of data.
SIMATIC ET 200M  Modular I/O system for cabinet installation and high channel densities 
in the SIMATIC S7‑300 packaging system.
SIMATIC ET 200SP Finely scalable I/O system for cabinet installation; ET 200SP features 
a single-cable and multi-cable connection with push‑in terminals, 
compact dimensions, high performance, and low part variety. 
SIMATIC ET 200S Finely scalable I/O system for control cabinet configuration and 
particularly time-critical applications; including motor starters, safety 
technology and individual grouping of load groups.
SIMATIC ET 200pro Modular I/O system with IP65/67 degree of protection for machine-
related applications with no control cabinet; with features such as 
compact designs, integrated PROFIsafe safety technology, 
PROFINET connection and live module replacement.
SIMATIC ET 200eco I/O system with IP65/67 degree of protection for cabinet-free use close 
to the machine with flexible and fast ECOFAST or M12 connection 
methods.
Other PROFIBUS I/O
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.
