Slave-to-slave communication

"Direct data exchange" is sometimes called "slave-to-slave communication" or "data
exchange broadcast". Here, slaves exchange data without any direct involvement of the
master.
You can find more information in: "Manuals for your inverter in the fieldbus function manual
(Page 387)".
6.2.2

Acyclically reading and writing inverter parameters

The inverter supports the writing and reading of parameters via acyclic communication:
● For PROFIBUS: Up to 240 bytes per write or read request via data set 47
● For PROFINET: Write or read requests via B02E hex and B02F hex
You will find more information on acyclic communication in the Fieldbus Function Manual;
see also section: Manuals for your inverter (Page 387).
