Object Directory - Structure
All the CANopen objects relevant for the Bus Coupler are entered into the CANopen object directory. The
object directory is divided into three different regions:
1. communication-specific profile region (index 0x1000 – 0x1FFF).
This contains the description of all the parameters specific to communication.
2. manufacturer-specific profile region (index 0x2000 – 0x5FFF).
Contains the description of the manufacturer-specific entries.
