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.
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.

Control via AS-i

6.2.5.1

Single slave mode

In Single Slave mode, four bits are available for the communication between the AS-i master
and the inverter. The four bits are used to transfer process data. In parallel, the control can
start a diagnostic request via AS-i.P0.
The following default settings are available; both work with profile 7.F.E.
● Default setting 30: Standard Single Slave mode
● Default setting 32: Modified Single Slave mode
Default setting 30: Standard Single Slave mode
In standard addressing, the control specifies the speed setpoint via the motor control bits
(AS-i.DO0 ... AS-i.DO3).
