C001H
• At initial processing, the IP address setting
value of the Ethernet module is incorrect.
• When using the router relay function, the
setting value of the sub-net mask field is
incorrect.
• Correct the IP address.
Set the class to A/B/C.
• Correct the sub-net mask.
C002H
At initial setting, some of the various timer
setting values are outside the allowable range.
• Review and correct the necessary timer
values at initial processing.
C004H
The setting value of the sub-net mask field is
incorrect.
• Correct the sub-net mask and execute the
initial processing again.
C005H
• The setting value of the default router IP
address for the router relay function is
incorrect.
• Network address (network address after sub-
net mask) of the default router IP address is
different from the network address of the local
station's Ethernet module IP address.
• Correct the default router IP address and
execute the initial processing again.
• Set the network address to the same network
address as the local station's Ethernet
module IP address.
C006H
The setting value of the sub-net address for the
router relay function is incorrect.
• Correct the sub-net address and execute the
initial processing again.
C007H
• The setting value of the router IP address for
the router relay function is incorrect.
• Network address (network address after sub-
net mask) of router IP address is different
from the network address of the local station's
Ethernet module IP address.
• Correct the router IP address and execute
the initial processing again.
• Set the network address to the same network
address as the local station's Ethernet
module IP address.
C010H
At open processing, the setting value of the
Ethernet module port number is incorrect. • Correct the port number.
C011H
At open processing, the setting value of an
external device's port number is incorrect. • Correct the port number.
C012H
The port number set is used in a connection
already opened by TCP/IP.
• Review and correct the port numbers of the
Ethernet module and external device.
C013H
The port number used in a connection already
opened is set in UDP/IP open processing.
• Review and correct the port number of the
Ethernet module.
C014H
Initial processing and open processing of the
Ethernet module is not completed.
• Execute the initial processing and open
processing.
C015H
At open processing, the setting value of an
external device's IP address is incorrect.
• Correct the IP address.
Set the class to A/B/C.
C016H
The pairing open processing of the connection
(or the next connection) designated for pairing
open has already been completed.
• Check that the open processing of both of
the target connections for pairing open is not
executed.
• Review the combination for pairing open.
C017H
A connection could not be established during
the open processing of a TCP connection.
• Check the operation of the external device.
• Check the open processing of the external
device.
• Correct the open settings of the
communication parameters.
• Review the Ethernet module's port number
and the IP address/port number and open
system of the external device.
• Check that the connection cable is not
dislocated.
C018H
The setting value of an external device's IP
address is incorrect.
* When TCP is used, FFFFFFFFH
cannot be set as an IP address.
• Correct the IP address.
