MR-JET-G-N1 User's Manual (Object Dictionary)
The data that a CAN application protocol over EtherCAT (CoE) device holds, such as control parameters, command values,
and feedback values, is handled as an object composed of an Index value, object name, object type, R/W attribute, and other
elements. The data is exchanged between the master and slave devices. The aggregate of these objects is called an object
dictionary (OD).
