Probable cause
Error information on the
Controller Link Unit (an
error log) has been
recorded.
The Controller Link Unit is
faulty.
Indicates that the network
parameters recorded in the
CPU Bus Unit Area in the
CPU Unit differ from the
values of the Network in
use.
The same node address
has been used more than
once.
An error has occurred
while writing data to the
EEPROM in the Controller
Link Unit.
Data is corrupted in the
CPU Bus Unit system
setup in the CPU Unit.
The PLC is protected.
The routing table data in
the CPU Unit's Parameter
Area is corrupted.
There is an error in the
routing table setting.
The data link table data in
the CS/CJ CPU Bus Unit
Area is corrupted.
There is an error in the
data link table settings.
Section 9-2
Probable remedy
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.
Replace the Controller Link
Unit.
Check the network param-
eters on the Network in
use using the Controller
Link Support Software, and
reset necessary parame-
ters.
Reset so that each node
address is used only once
within the same Network.
The EEPROM in the Con-
troller Link Unit is for stor-
ing error log data. If the
error occurs again, replace
the CPU Unit.
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.
Set the PLC's protect
switch to OFF.
Refer to 7-4 Setting Rout-
ing Tables and reset the
routing tables correctly. If
the error occurs again,
replace the Controller Link
Unit.
When using a routing
table, refer to 7-4 Setting
Routing Tables and reset
the routing tables correctly.
If no routing tables are
being used, delete the
tables.
Refer to 5-3 Starting and
Stopping Data Links and
reset the data link tables
correctly. If the error occurs
again, replace the CPU
Unit.
When using manually set
data links, refer to 5-3
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.
