With "Read record" and "Write record", PROFINET offers acyclic services that can be
used to transfer parameter data between the PROFINET controller (master) and a
PROFINET device (slave). Via UDP (User Datagram Protocol), the priority of this data
exchange is lower than the priority of the process data exchange.

The user data transported via an acyclic PROFINET service is grouped in a data set.
Each dataset is clearly addressed by the following characteristics:
•
API
•
Slot number
•
Subslot number
•
Index
The structure of data set 47 is used for the parameter exchange with
SEW‑EURODRIVE PROFINET devices. The structure of data set 47 is specified in
the PROFIdrive profile drive technology of the PROFIBUS user organization; as of
V4.0 as PROFINET parameter channel. Different procedures for accessing parameter
data of the SEW‑EURODRIVE PROFINET device are provided via this parameter
channel.
