Slave-to-slave communication

"Direct data exchange" is sometimes called "slave-to-slave communication" or "data
exchange broadcast". With direct data exchange, slaves exchange data without any direct
involvement of the master.
Further information about the "Direct data exchange" function is provided in the Fieldbus
function manual.
6.2.4.7

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
Further information about acyclic communication is provided in the Fieldbus function manual.
