Object Dictionary
The CAN application protocol over EtherCAT (CoE) protocol uses the object dictionary of CAN
application protocol as its base. Each object is assigned with an index of four-digit hexadecimal value.
The indexes are configured in the areas below.
This profile uses the following data types.
