Use Data Structure as Defined in PROFIdrive Profile V4.1
Introduction
The SINAMICS G120 range of inverters can be controlled through the cyclical
PROFIBUS DP channel or the acyclic DPV1 channel. The structure of use data for the
cyclic/acyclic channel for is defined in the PROFIdrive Profile, version V4.1.
The PROFIdrive profile defines the inverters, the use data structure with which a master can
access the inverters (slaves) using the cyclic or acyclic data communication method.
Note
PROFIdrive for drive technology is standardized and described in the following document:

Telegram data structure
The use data structure for cyclical data traffic is divided into two areas which can be
transmitted in each telegram:
● Process data area (PZD)
Process data includes control words (status information) and setpoints (actual values).
Process data are transmitted in the process data area.
The transferred process data do not take effect until the bits used in the control words,
setpoints, status words and actual values have been routed in the inverter.
● Parameter channel
This area is reserved for reading/writing parameter values.
This telegram section is used to monitor and/or change any parameter in the inverter. For
further information to the parameter channel, refer the Function Manual.
