5.1 The Object Channel
5.1.1 Objects >3500h Manufacturer specific object channel
The Object Dictionary has been expanded beyond Index 3500
h
(reserved object range 3500
h
...
3900
h
) for all Device Objects that can be described in up to 4 bytes of user data.
This range can be dynamically extended, i.e. if extensions are made, new device parameters that
fulfil the above-mentioned format are automatically added to the table for the core firmware.
Object 3500
h
(Subindex 01
h
, read) can be used to show the total number of objects in the Object
Channel (Þ p.101).
The objects in the Object Channel (ASCII parameters) cannot be mapped in a PDO!
Each object in this range is described with the aid of 8 Sub-indices. The structure is built up as fol
