3 Connection Establishment to SINAMICS S120
You are provided with information on…
how to access SINAMICS S120 online via the S7T Config configuration
tool.
3.1 Connecting the hardware components
Interfacing SINAMICS S120 to the S7T Config configuration tool is always
performed via the technology CPU.
SINAMICS S120 is connected to the technology CPU via the DP(Drive)
interface. The configuration computer, however, is connected to the CPU
via the Profibus interface. A direct connection between configuration
computer and SINAMICS S120 for configuration via S7T Config is not
possible.

3.2 Setting the Profibus address
Basically, we recommend setting a fixed Profibus address directly at
SINAMICS S120 via the DIP switches for the operation of SINAMICS S120
with the technology CPU.
The DIP switches for setting the Profibus address are located below the
cover plate at the lower end of the control unit.
The Profibus address is entered via the DIP switches in binary coded form
in the range of 1…126. When setting the values 0 (all switches OFF) or 127
(all switches ON), the Profibus address set in the parameter p0918 is used
for the communication.
