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.
C002
H
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.
C004
H
The setting value of the sub-net mask field is
incorrect.
• Correct the sub-net mask and execute the
initial processing again.
C005
H
• 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.
C006
H
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.
C007
H
• 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.
C010
H
At open processing, the setting value of the
Ethernet module port number is incorrect.
• Correct the port number.
C011
H
At open processing, the setting value of an
external device's port number is incorrect.
• Correct the port number.
C012
H
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.
C013
H
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.
C014
H
Initial processing and open processing of the
Ethernet module is not completed.
• Execute the initial processing and open
processing.
C015
H
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.
C016
H
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.
C017
H
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, FFFFFFFF
H
cannot be set as an IP address.
• Correct the IP address.
