Data transfer using CANopen

3.1

MICROMASTER object directory

All of the objects of the object directory are listed in the following table. The table
contains the index and subindex of the object as well as a brief description of the
functionality and the data type as well as the default value.
For each object, it is defined as to how it can be transferred. In this case, a
differentiation is made between the two possibilities - SDO and PDO transfer. In
addition, the parameters or connectors, in which the object data are located, are
also listed. If both possibilities are specified in the table, then data transfer can
either be realized as SDO or as PDO.
For more detailed information about the objects, please refer to the CANopen
profiles DS 301 V4.0 and DSP 402 V1.1.
