Selection help for the PROFIdrive message frames 
By default, the SINAMICS S120 is connected to the Technology CPU via PROFIBUS DP 
(DRIVE). Depending on the desired axis functionality, this connection can be made using 
various device-specific message frames. The following selection table shows the properties 
of the individual message types.

Note 
Message frame types < 100 are standard message frames whose structure is standardized 
by the PROFIdrive profile V3. 
The message frame types > 100 are manufacturer-specific message frames. 
Structure of the PROFIdrive message frames 
If special functions of the drive are to be used or supported, the use of special PROFIdrive 
message frames may be required. 
The following figure shows which data are transferred with each message frame type and 
consequently which functions of the drive can be supported.
