Data structures within PROFIdrive Profile
User data structure defined in PROFIdrive Profile 4.0
The SINAMICS G120 range of inverters can be controlled through the cyclical
PROFIBUS DP channel. The structure of user data for the cyclical/acyclical channel is
defined in the PROFIdrive Profile, version 4.0.
The PROFIdrive Profile defines for the inverters, the user data structure with which a master
can access the inverter slaves using the cyclical/acyclical data communication method.
Extended configuration for the SINAMICS G120
Up to 6 process data words (PZD), with a different number of setpoints and actual values if
desired, can be configured on the SINAMICS G120. They are combined to standard and
manufacturer-specific telegrams.
Telegrams
The selection of a telegram via P0922 determines on the drive unit side which process data
