With CM 1243-5, the SIMATIC S7-1200 can be operated as a PROFIBUS master.
A SINAMICS drive can be used as PROFIBUS slave and be controlled by
SIMATIC S7-1200. The application description covers the following drive types
(with FW ≥ V4.6):
 G110M
 G120 with CU240E-2 DP or CU250S-2 DP
 G120C DP
 G120D with CU240D-2 DP
 G120P with CU230P-2 DP
The abbreviation G120 used in this document refers to the above devices. Using
the example of a SINAMICS G120C DP with PROFIBUS DB interface illustrates
how to configure the drive, start it up, and access process data and parameters.

Explanation
Access to process data
The SINAMICS G120 shall be switched on and off via the
control word, and the speed value is to be specified as quickly
as possible.
Access to parameters
Read and write access from the SIMATIC S7-1200 to the
parameters in the SINAMICS converter (in this example: ramp-
up and ramp-downtime) should be possible
and performed using as few resources as possible, i.e. small
communication load.
Safety function of the
SINAMICS G120
The SINAMICS G120 has the option of performing a fail-safe
shutdown (STO).
