Error details
Disconnection of the data transfer port to the
FTP server failed.
The connection number setting is invalid.
The specified connection has already completed
OPEN processing.
The specified connection has not completed
OPEN processing.
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" was specified in
"Destination" of the simple PLC communication
function, the function was executed while CPU
exchange timing setting (SW7) of the Ethernet
module is off and the CPU module on the
destination is in the RUN status.
• Contents of control data is not correct.
• Open instruction was executed through open
settings parameter even though parameters
are not set for "Open settings".
An error occurred during file transfer to the FTP
server.
Multiple file transfer function (FTP client)
instructions are executed simultaneously.
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" was specified in
"Destination" of the simple PLC communication
function, communications between the CPU
module and the Ethernet module failed. (After
the Ethernet module normally receives a request
from another node, communications between the
CPU module and the Ethernet module ailed due
to a noise or other causes.)
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" is specified in
"Destination" of the simple PLC communication
function, an incorrect device is specified.
When "MELSEC-A (Ethernet Module)/MELSEC-
FX3 (Ethernet Block/Adapter)" was specified in
"Destination" of the simple PLC communication
function, a system error occurred. (The possible
cause is malfunction due to noise or other
causes or hardware failure).
Corrective action
• Check connection with the FTP server.
• Correct "Data transfer mode" in the "FTP
setting" window.
• When a firewall is active or the proxy server is
on the connection path, consult the network
administrator about the settings.
• Specify the connection No. within 1 to 16.
• When using socket communication, check
whether "Socket communication" is selected for
"Open system" parameter.
• When using predefined protocol function, check
whether "Predefined protocol" is selected for
"Open system" parameter.
Perform CLOSE processing and then OPEN
processing.
Re-execute after OPEN processing is completed.
• Turn on CPU exchange timing setting (SW7) of
the destination.
• Set the CPU module on the destination to STOP
and execute the function again.
• Correct the contents of the control data.
• Configure the open settings parameters or
execute the OPEN instruction through control
data.
• Delete unnecessary files on the FTP server to
increase free space.
• Check the connection status of the FTP server.
After the processing of the file transfer function
(FTP client) instruction being executed ends,
execute another file transfer function (FTP client)
instruction.
• Ensure that the operating environment for the
system meets the general specifications of the
CPU module.
• Reset the CPU module.
• Execute again. If the same error code is
displayed, the cause is a hardware failure of the
CPU module. Please consult your local
Mitsubishi representative.
• Check the specified device name.
• Check the specified device No.
• Check the device assignment parameters of the
CPU module (destination).
• Check that the power supply module and the
CPU module are mounted/connected properly.
• Ensure that the operating environment for the
system meets the general specifications of the
CPU module.
• Check whether the power capacity is sufficient.
• Reset the CPU module.
• Execute again. If the same error code is
displayed, the cause is a hardware failure of the
CPU module. Please consult your local
Mitsubishi representative.
