Error Codes
For the error codes (stored in SD0/SD8067) common among CPU modules, refer to the MELSEC iQ-F FX5 User's
Manual (Application).
Error codes of the IP address change function
The description and corrective action for error codes generated by the IP address change function are explained.
Error codes are stored in SD8498 (IP address storage area write error code) or SD8499 (IP address storage area clear error
code).
Error code
Error details and causes
(Hexadecimal)
1920H
IP address setting or other (SD8492 to SD8497) value exceeds
the setting range.
1921H
Write request and clear request (SM8492 and SM8495) turned
from OFF to ON simultaneously.
Error codes of the Ethernet communication
This section contains an explanation of the contents and method of handling of error codes for errors that occur during various
processing for data communication between CPU module (built-in Ethernet) and other devices, and processing requests from
own station (built-in Ethernet).
Error codes are stored in built-in Ethernet error code SD10130 (connection 1) to SD10137 (connection 8). However, in case of
multiple errors, the error code of the last error that occurred is stored in SD10130 (connection 1) to SD10137 (connection 8).
Error code
Error details and causes
(Hexadecimal)
1120H
Clock setting has failed when the system is powered on or the
CPU module is reset.
112EH
Connection could not be established in open processing.
1134H
A TCP ULP timeout error has occurred in the TCP/IP
communication. (The external device does not send an ACK
response.)
2160H
Overlapping IP addresses were detected.
2250H
The protocol setting data stored in the CPU module is not for
(Stores in SD0)
available modules.
C012H
Open processing with the external device failed. (For TCP/IP)
C013H
Open processing with the external device failed. (For UDP/IP)
C015H
• The specified IP address of the external device for the open
processing is incorrect.
• The specified IP address of the external device of the dedicated
instruction is incorrect.
C020H
The send/receive data length exceeds the allowable range.
C024H
Communication using communication protocol is executed in a
connection whose connection method is other than
communication protocol.

13.4 Error Codes
Action
Correct the IP address setting or other (SD8492 to SD8497) value.
Check if write request and clear request (SM8492 and SM8495)
turned from OFF to ON simultaneously.
Action
• Check if the time settings are correctly set in parameter.
• Check if the specified SNTP server is operating normally and there
is no failure on the network accessing to the SNTP server
computer.
• Check the operation of the external device.
• Check if open processing has been performed in the external
device.
• Correct the port number of the CPU module, IP address/port
number of the external device, and opening method.
• When a firewall is set in the external device, check if access is
permitted.
• Check if the IP address of the external device is not denied in IP
Filter Settings.
• Check if the Ethernet cable is disconnected.
• Check the operation of the external device.
• Correct the TCP ULP timeout value of the CPU module.
• Since there may be congestion of packets on the line, send data
after a certain period of time.
• Check if the connection cable is disconnected.
Check and correct the IP addresses.
Write the protocol setting data for available modules to the CPU
module.
Correct the port numbers of the CPU module and the external device.
Correct the port numbers of the CPU module and the external device.
Execute the dedicated instruction again after correcting the specified
IP address of the external device.
• Correct the data length to be sent.
• When the amount of data to be sent exceeds the limit, divide the
data into smaller chunks to send it.
• Check that there is no error in the connection number specification
of the dedicated instruction.
• Correct the communication method of the connection with the
external device.
