3 TROUBLESHOOTING
3.5 List of Error Codes
C061H • The request data length of the SLMP message does
not match with the number 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.
• Check and correct the text or request data length, and
send the SLMP message to the Ethernet-equipped
module again.
• Add the dummy data for one byte, and specify the
length by even byte.
• Check the operating status and connection status of
the target device of when the iQSS function is
executed.
• Check the connection of an Ethernet cable and a hub
of when the iQSS function is executed.
• Check the line status of Ethernet of when the iQSS
function is executed.
• Reset the CPU module and device to be targets of the
iQSS function, and retry the operation.
For the error occurred when the iQSS function is
executed, contact the manufacturer of the target device if
the above actions do not solve the problem.
C070H The device memory cannot be extended for the access
destination specified by the SLMP message.
• 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 R/Q/
QnACPU via CC-Link IE Controller Network,
MELSECNET/H, or MELSECNET/10.
C071H The number of device points for data read/write set for
modules other than an R/Q/QnACPU is out of the range.
Correct the number of read/write points and send the
SLMP message to the Ethernet-equipped module again.
C072H The request details of the SLMP message is incorrect.
(For example, a request for data read/write in bit units
has been issued to a word device.)
• 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.
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 R/Q/QnACPU.)
Correct the request details of the SLMP message.
C075H The request data length for the label access is out of
range.
• 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.
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.
Finish all the communications to perform the
reinitialization processing of the Ethernet-equipped
module.
C083H The communication processing was abnormally ended in
the link dedicated instruction communications
• Check if the relay station and external station are
operating normally.
• Check if there is an error with the cable connection
between the own station and the external station.
• If the line is heavily loaded, reduce the load, and retry
the operation.
• Increase the number of resends for the link dedicated
instructions and execute the operation.
C084H The communication processing was abnormally ended in
the link dedicated instruction communications
• Check if the own station/relay station/external station is
operating normally.
• Check if there is an error with the cable connection
between the own station and the external station.
• Increase the TCP resend timer value of the Ethernet-
equipped module.
C085H The target station's channel specified by the link
dedicated instruction SEND is currently in use.
Correct the target station's channel of the SEND
instruction.
