5.4 Transmitting parameter data
Parameter data are the indices.
The parameters are mostly set once during commissioning.
Parameter data are transmitted as SDOs (Service Data Objects) via the system bus and confirmed by
the receiver, i.e., the transmitter receives a feedback whether the transmission was successful.
