Status Area and Troubleshooting Section 10-2
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 (except
for Units used in duplex
operation).
The Unit is connected
to a SYSMAC LINK net-
work (Optical Units
only). Check the network and
reconnect cables cor-
rectly.
EEPROM error (CIO 1500 + 25
×
n,
bit 7) is 1: ON
An error has occurred
while writing data to the
CPU Unit’s EEPROM. Check the status of bits
00 to 02 in CIO 1500 +
25
×
n, and correct any
problems found. If the
error occurs again,
replace the CPU Unit.
PLC system setting error (CIO 1500
+ 25
×
n, bit 3) is 1: ON
The CPU Unit’s
EEPROM data is dam-
aged. Check the status of bits
00 to 02 in CIO 1500 +
25
×
n, and correct any
problems 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 damaged. Refer to 7-4 Setting
Routing Tables 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 7-4 Set-
ting Routing Tables 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 CPU Bus Unit
Area is damaged. 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.
There is an error in the
data link table settings. When using manually
set data links, refer to 5-
3 Starting and Stopping
Data Links and remake
and set the data link
