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.

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.
