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
CS/CJ Bus Unit Area differ
from the values of the Net-
work in use.
The same node address
has been used more than
once.
An error has occurred
while writing data to the
CPU Unit's EEPROM.
The CPU Unit's EEPROM
data is damaged.
The PLC is protected.
The routing table data
within the CPU Unit's
EEPROM is damaged.
There is an error in the
routing table setting.
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.
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.
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.
