Error description
code
Some of the various timer setting values for the initial
C002
H
process are outside the allowable range.
The setting value of the auto-open UDP port number for
C003
H
the initial process is outside the allowable range.
C004
The setting value of the subnet mask field is incorrect.
H
• The setting value of the default router IP address for
the router relay function is incorrect.
• The network address (network address after the
C005
H
subnet mask) of the default router IP address is
different from that of the IP address of the Ethernet
module in the own station.
The setting value of the subnet address for the router
C006
H
relay function is incorrect.
• The setting value of the router IP address for the
router relay function is incorrect.
• The network address (network address after the
C007
H
subnet mask) of the router IP address is different from
that of the IP address of the Ethernet module in the
own station.
The send/receive process has been executed while the
C00E
H
IP address in use detection function is being executed.
C00F
One IP address is used for two or more modules.
H
The setting value of the Ethernet module port number
C010
H
for the open process is incorrect.
The setting value of the port number of the connected
C011
H
device for the open process is incorrect.
The port number set is used in a connection already
C012
H
opened in TCP/IP.
The port number used in a connection already opened
C013
H
is set for the open process in UDP/IP.
The initial process or open process of the Ethernet
C014
H
module is not completed.
The setting value of the IP address of the connected
C015
H
device for the open process is incorrect.
The open process of the connection (or the next
C016
connection) specified for pairing open has been already
H
completed.
A connection could not be established in the open
C017
H
process of the TCP connection.
The setting value of the IP address of the connected
C018
H
device is incorrect.
C020
The data length exceeds the allowable range.
H
Action
• Check and correct each timer setting value for the initial process.
• Check and correct the auto-open UDP port number.
• Correct the subnet mask and perform the initial process again.
• Correct the default router IP address and perform the initial
process again.
• Set the same network address as that of the IP address of the
Ethernet module in the own station.
• Correct the subnet address and perform the initial process again.
• Correct the router IP address and perform the initial process again.
• Change the IP address of the Ethernet module in the own station
to the same address as the network address.
Do not execute the send/receive process while executing the IP
address in use detection function.
• Set different IP addresses.
The MAC addresses of the Ethernet modules in the stations with the
same IP address can be checked in IP address duplication status
storage area (5281 to 5286 ).
H H
• Correct the port number.
• Correct the port number.
• Correct the port numbers of the Ethernet module and the
connected device.
• Correct the port number of the Ethernet module.
• Perform the initial process or open process.
• Correct the IP address. Set the class to A/B/C.
• Check that none of the connections targeted for pairing open has
been opened.
• Correct the combination of modules set for pairing open.
• Check the operation of the connected device.
• Check the open process of the connected device.
• Correct the open setting of the communication parameters.
• Correct the port number of the Ethernet module, the IP address
and port number of the connected device, and the open setting.
• Check if the cable is disconnected.
• Correct the IP address.
• Correct the data length.
• When the amount of data to be sent exceeds the limit, divide the
data into smaller chunks to send it.
