Error log exists (CIO 1500
+ 25
×
n, bit 15) is 1: ON
Error information on the
Controller Link Unit (an
error log) has been
recorded.
Using the Controller Link
Support Software or an
FINS command, read the
cause of the current error.
Alternatively, use past error
log records to troubleshoot
the problem.
Communications controller
send error (CIO 1500 + 25
×
n, bit 11) is 1: ON
The Controller Link Unit is
faulty.
Replace the Controller Link
Unit.
Inconsistent network
parameters (CIO 1500 +
25
×
n, bit 10) is 1: ON
Indicates that the network
parameters recorded in the
Controller Link Unit’s
EEPROM differ from the
values of the Network in
use.
Check the network param-
eters on the Network in
use using the Controller
Link Support Software, and
reset necessary parame-
ters.
Node address duplicate
setting error (CIO 1500 +
25
×
n, bit 9) is 1: ON
The same node address
has been used more than
once.
Reset so that each node
address is used only once
within the same Network.
EEPROM error (CIO 1500
+ 25
×
n, bit 7) is 1: ON
An error has occurred
while writing data to the
Controller Link Unit’s
EEPROM.
The EEPROM in the Con-
troller Link Unit is used to
store the error log.
If this error persists,
replace the CPU Unit.
PLC system setting error
(CIO 1500 + 25
×
n, bit 3)
is 1: ON
The system settings for the
Controller Link Unit as a
CPU Bus Unit in the CPU
Unit are corrupted.
Check the status of bits 00
to 02 in (CIO 1500 + 25
×
n, and correct any prob-
lems found. If the error
occurs again, replace the
CPU Unit.
The PLC is protected.
Set the PLC’s protect
switch to OFF.
Routing table error
(CIO 1500 + 25
×
n, bit 2)
is 1: ON
The routing table data
within the CPU Unit’s
EEPROM is corrupted.
and reset the
routing tables correctly. If
the error occurs again,
replace the Controller Link
Unit.
There is an error in the
routing table setting.
When using a routing
table, refer to
and reset
the routing tables correctly.
If no routing tables are
being used, delete the
tables.
Data link table error
(CIO 1500 + 25
×
n, bit 1)
is 1: ON
The data link table data in
the EEPROM of the CPU
Unit is corrupted.
and
reset the data link tables
correctly. If the error occurs
again, replace the CPU
Unit.
There is an error in the
data link table settings.
When using manually set
data links, refer to
Starting and Stopping Data
Links
and remake and set
the data link tables cor-
rectly. When manually set
data links are not being
used, delete the data link
tables.
