8. Object Dictionary
These reference design follows CiA402 device profile and used as an interface to integrate Motor Control
Stack and EtherCAT Slave Stack, the CiA402 protocol implement a state machine and object dictionary for
external EtherCAT master access, Master side can control motor, switch operation mode and monitor motor
status by manipulation of object dictionary.
8-1 Objects Description
This section lists out all supported objects in the reference design, please note that some objects may not
implemented actual functions with Motor Control Stack side, but they are accessible in EtherCAT Slave side,
so developer can still add application functions on them.
Object type definition are as below
Object Type
Description
VAR
A single value
ARRAY
A multiple data field object where each data field is a simple variable of same
basic data type.
RECORD
A multiple data field object where the data fields may be any combination of
simple variables.
