1.2  System components 
Central components 
SIMOTION D4x5 communicates with automation components via the following interfaces:   
●  PROFIBUS DP 
●  Ethernet 
●  PROFINET IO (when using a CBE30) 
●  DRIVE-CLiQ (DRIVE Component Link with IQ). 
SIMOTION D features a SINAMICS Integrated drive element. Communication with the 
SINAMICS Integrated is via PROFIBUS mechanisms (DP Integrated). 
The most important components of the system and their functions are shown below. 
Table 1- 1  Central components  
Component  Function 
SIMOTION D4x5 controller  ... is the central motion control module.  
This module contains the programmable SIMOTION runtime for the 
SIMOTION D4x5 and the SINAMICS S120 drive software. 
You can use the integrated high-speed digital I/Os as: 
•  Homing inputs 
•  Inputs for measuring inputs 
•  User-addressable process I/Os 
•  Outputs for fast output cams 
The measuring sockets can output any analog signals. 
System software  The basic functionality of SIMOTION D is supplied on a CompactFlash 
card containing the following: 
•  SIMOTION runtime (kernel) 
•  Drive software of SINAMICS S120 - implements all drive functions 
Power supply  ... provides the electronic power supply for SIMOTION D, e.g. via the 
SITOP power supply.
