Basics
Object Dictionary
Description
Each CANopen device manages an object dictionary which contains the objects for communication.
Index and Subindex
The objects are addressed in the object dictionary via a 16 bit index.
One or more 8 bit subindex entries for each object specify individual data fields in the object. Index and
subindex are shown in hexadecimal notation.
The following table provides the index and subindex entries using the example of the object ramps (203C
hex):
