List of Error Codes

This section lists the error codes, error details and causes, and action for the errors occur in the processing for data
communication between the Ethernet-equipped module and slave stations or caused by processing requests from the CPU
module on the own station.
Error codes are classified into major error, moderate error, and minor error, and can be checked in the [Error Information] tab
in the "Module Diagnostics" window of an Ethernet-equipped module. ( Page 282 Error Information)
Error Error details and causes
code
1080H The number of writes to the flash ROM has exceeded

1128H The port number is incorrect.
1129H The port number of the external device is not set
correctly.
112CH The request using all stations specification has failed.
112DH The data was sent to the external device while the IP
address setting of the device set in "External Device
Configuration" under "Basic Settings" was incorrect.
112EH A connection could not be established in the open
processing.
1133H The response send failed during socket communications
or communications using the fixed buffer.

Action
Replace the module.
• 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.
• Correct the default gateway IP address.
• Set the same network address as that of the IP
address.
Correct the port number.
Correct the port number of the external device.
Try the request using current station specification.
• Correct the IP address of the external device in
"External Device Configuration" under "Basic
Settings".
• Check that the IP address class of the external device
is set to A/B/C in "External Device Configuration"
under "Basic Settings".
• Check the operation of the external device.
• Check if the open processing has been performed in
the external device.
• Correct the port number of the Ethernet-equipped
module, IP address/port number of the external device,
and opening method.
• When the firewall is set in the external device, check if
the access is permitted.
• Check if the Ethernet cable is disconnected.
• Check the operation of the external device or switching
hub.
• 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 that there is no connection failure with the
switching hub.
• Execute the communication status test, and if the test
was completed with an error, take the corrective action.
• Execute the module communication test, and check
that there is no failure in the module.
• Check the operation of the external device.
• Correct the TCP ULP timeout value of the Ethernet-
equipped 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.
• Correct the IP addresses.
• Set different IP addresses for port 1 and port 2.
