Error Error definition and causes
code
C05DH The "Monitor Request" command is
received before the monitor registration is
performed by the "Monitor Registration/
Clear" command of the SLMP message.
C05EH The time between reception of the SLMP
message by the Ethernet-equipped
module and the returned response from
the access destination exceeded the
monitoring timer value set in the SLMP
command.
C05FH This request cannot be executed to the
access destination specified by the SLMP
message.
C060H The request details for bit devices of the
SLMP message is incorrect.
C061H • The request data length of the SLMP
message does not match the No. of data
in the character (a part of text).
• The write data length specified by the
label write command is not even byte.
• When the iQSS function is executed,
incorrect frame is received.
C06FH The network No. of request destination
specified by the SLMP request message is
not available for communications with the
station No. 121 or larger.
C070H The device memory cannot be extended
for the access destination specified by the
SLMP message.
C071H The number of device points for data read/
write set for modules other than a
MELSEC iQ-R/Q/QnACPU is out of the
range.
C072H The request details of the SLMP message
are incorrect. (For example, a request for
data read/write in bit units has been issued
to a word device.)
C073H The access destination of the SLMP
message cannot issue this request. (For
example, the number of double word
access points cannot be specified for
modules other than a MELSEC iQ-R/Q/
QnACPU.)
C075H The request data length for the label
access is out of range.
C081H The termination processing for the
Ethernet-equipped module that is involved
with the reinitialization processing is being
performed, and arrival of link dedicated
instructions cannot be checked.
C087H IP address of the destination external
device could not be acquired.

3.5 List of Error Codes
Action
Register the monitoring data using "Monitor Registration/Clear" command
and perform monitoring.
• Increase the monitoring timer value.
• Check if the access destination is operating normally.
• Correct the network No. or request destination station No..
• If the access destination is a module with a different network No., correct
the routing parameter setting.
• If the access destination is a module with a different network No., check if
the network No. is not in use.
Correct the access destination.
Correct the request details and send the SLMP message to the Ethernet-
equipped module again.
• Check and correct the text or request data length, and send the SLMP
message to the Ethernet-equipped module again.
• Add one byte of dummy data, and specify the length as an even number of
bytes.
• Check the operating status and connection status of the target device at
the time the iQSS function is executed.
• Check the connection of the Ethernet cable and hub at the time the iQSS
function is executed.
• Check the line status of Ethernet at the time the iQSS function is executed.
• Reset the CPU module and device to be targets of the iQSS function, and
retry the operation.
For errors that occur when the iQSS function is executed, contact the
manufacturer of the target device if the above actions do not solve the
problem.
• If the SLMP3E or 4E frame is used, check that there is no error for the
network No. of request destination and station No..
• If the SLMP6E frame is used, check that there is no error for the network
number of request destination, station No., and extension station No..
• Correct the SLMP message to read/write data without the device memory
set for extension.
• Specify the extension of the device memory only for an Ethernet-equipped
module mounted station and a MELSEC iQ-R/Q/QnACPU via CC-Link IE
Controller Network, MELSECNET/H, or MELSECNET/10.
Correct the number of read/write points and send the SLMP message to the
Ethernet-equipped module again.
• Check if the data can be requested to the access destination.
• Correct the request details and send the SLMP message to the Ethernet-
equipped module again.
Correct the request details of the SLMP message.
• Correct the number of read/write points and send the SLMP message to
the Ethernet-equipped module again.
• Correct the label to shorten the label name and send the SLMP message
to the Ethernet-equipped module again.
Finish all the communications to perform the reinitialization processing of the
Ethernet-equipped module.
• Correct the IP address in the network station No.  IP information setting.
• Check if the network or station No. of the external device is correctly
specified by using control data of the dedicated instruction.
• Check if the connection cable is disconnected.
