Manufacturer specific object channel (from PNU 1600)
The object catalogue was expanded by all existing parameters and commands from PNU 1600 on
(reserved object range PNU 1600 - PNU 2000).
This object range is called SDO channel (SDO - Service Data Object). The SDO channel is
expansible dynamically, new parameters will be added to the table
automatically
. The PNU is cal-
culated by 1600 + ASCII object number.
Each of the object in the SDO channel is described by 8 subindexes (octet 3).
In the following, the structure of the subindexes is shown:
