A-5 CoE Objects
This section explains the CoE objects that are implemented by the EtherCAT Coupler Unit.
The CAN application protocol over EtherCAT (CoE) is based on the object dictionary for the CAN appli-
cation protocol.
All objects are assigned 4-digit hexadecimal indexes. The objects are structured in the following areas.
The following data types are used in this profile.
