3.3.4  Activating routing in NetPro 
Introduction 
To establish an online connection between the programming device and the 
SINAMICS S120 drive system, the "Routing of a SIMATIC PC station" in NetPro 
must be activated. 
This is necessary because the programming device is connected via the X1-MPI/DP 
interface to the technology CPU and to the SINAMICS S120 on the PROFIBUS DP (DRIVE) 
of the Technology CPU. 
To allow the programming device to access the SINAMICS S120 online, a routing must take 
place between the X1-MPI/DP interface and the PROFIBUS DP (DRIVE) through the 
Technology CPU.
