Duplicate Operating Lev-
els/Refresh Error:
Operating level 0: AR0011
Operating level 1: AR0010
One of the above flags is 1:
ON
The same operating level is
set twice within the same
PLC.
If two units are required,
set them to different oper-
ating levels.
A refresh error has
occurred between the PLC
and the Unit.
Secure the Controller Link
Unit firmly.
For C200HX/HG/HE PLCs,
tighten the screws on the
Bus Connection Unit.
If the error occurs even
when the Unit is mounted
on another PLC, replace
the Controller Link Unit.
Routing Table Error/Unit
Restart:
Operating level 0: AR0113
Operating level 1: AR0112
One of the above flags is 1:
ON
The routing table data
within the DM Area is dam-
aged.
Refer to 7-4 Setting Rout-
ing Tables and reset cor-
rectly. If the error occurs
again, replace the Control-
ler Link Unit.
There is an error in the
routing table setting or a
Routing Table Enable Bit
(software switch) setting
error.
When using routing tables
refer to 7-4 Setting Routing
Tables and reset them cor-
rectly.
When no routing tables are
being used, turn OFF the
Routing Table Enable Flag.
Communications controller
hardware error:
Operating level 0: AR1114
Operating level 1: AR1514
One of the above flags is 1:
ON
The Controller Link Unit is
faulty.
Replace the Controller Link
Unit.
EEPROM error:
Operating level 0: AR1115
Operating level 1: AR1515
One of the above flags is 1:
ON
An error occurred when
writing data to EEPROM.
Remake and set the data
link table and the network
parameters. If the error
occurs again, replace the
Controller Link Unit.
The EEPROM data link
tables or the network
parameters are damaged.
There is an error in the
data link or network param-
eter settings.
Inconsistent network
parameters:
Operating level 0: AR2407
Operating level 1: AR2406
One of the above flags is 1:
ON
Indicates that the network
parameters in the
EEPROM of the Controller
Link Unit differ from those
in the Network.
Check the network param-
eters on the Network,
using the Controller Link
Support Software, and
reset the necessary
parameters.
