9.16 CANopen over EtherCAT (CoE)
The CoE protocol over EtherCAT uses a modified form of the CANopen
object dictionary. This is specified in Table 9-8.
Table 9-8 CoE object dictionary
The object description format describes object related information such
as size, range and descriptions and is detailed in Table 9-9.
Table 9-9 Object description format
For entries having sub-indices
Table 9-10 Object description format with sub-indices
Definitions:
• <index> : A signed 16-bit number. This is the index of the object
dictionary entry specified in four hexadecimal characters.
• <access> : A value describing how the object may be accessed (RW
= read/write, RO = read-only and WO = write-only).
• <size> : The size of the object/sub-index in bytes.
• <unit> : The physical unit (e.g. ms, counts per second etc.).
9.16.1 CoE communication area
The first set of objects specify general communication settings.
