10.5 Transmitting parameter data
Parameter data are the so-called indices.
Parameters are usually set only once during the commissioning.
Parameter data are transmitted as so-called SDOs (
Service Data Objects )viathe
system bus and acknowledged by the receiver, i.e. the transmitter gets a feedback
if the transmission was successful.

There is an offset of 64 between the identifiers for parameter
channels 1 and 2:
z Output of parameter channel 1 = 1536
z Output of parameter channel 2 = 1536 + 64 = 1600
