being used by two different
Units.
The Unit is connected to a
SYSMAC LINK Network
(Optical Units only).
Routing table setting error
The Unit is mounted to a
non-compatible PLC.
An error has occurred in
the PLC.
EEPROM error
Two Units connected to the
same PLC have the same
unit number.
Either there is an error in
the PLC I/O table or no
table has been created.
Probable cause
Check the power supply
voltage and supply at the
recommended voltage.
Secure the Controller Link
Unit firmly.
Refer to CS-series PLCs
or CJ-series PLCs and
mount the Unit correctly.
If the indicators do not light
when the Unit is mounted
in another PLC, replace
the Controller Link Unit.
Reset so that each node
address is used only once
within the same Network.
Check the Network and
reconnect cables correctly.
Remake and set the rout-
ing table correctly, referring
to 7-4 Setting Routing
Tables. When no routing
table is being used, delete
the routing table.
Refer to 1-2-4 Controller
Link Unit Models and PLCs
and reinstall the Unit on
the appropriate PLC.
Refer to the PLC’s opera-
tion manual and correct
the error. If the error occurs
again, replace the PLC.
Refer to 9-2 Status Area
and Troubleshooting, cor-
rect the data where the
error has occurred, and
reset the Unit. If the error
occurs again, replace the
Controller Link Unit.
Reset so that Units con-
nected to the same PLC
(including the CPU Expan-
sion Racks), do not have
the same unit number.
Create a correct I/O table
for the PLC.
