A-1 CoE Objects
This section describes the CoE objects that are implemented in the IO-Link Master Unit.
Precautions for Safe Use
After you change the settings of the IO-Link Master Unit, always sufficiently check the safety at
the connected devices before you cycle the power supply.
A-1-1
Object Dictionary Area
The CAN application protocol over EtherCAT (CoE) is based on the object dictionary for the CAN ap-
plication protocol.
All objects are assigned 4-digit hexadecimal indexes and consist of the following areas.
Index
0000 hex to
0FFF hex
1000 hex to
1FFF hex
2000 hex to
2FFF hex
3000 hex to
5FFF hex
6000 hex to
9FFF hex
A000 hex to
EFFF hex
F000 hex to
FFFF hex
