10 TROUBLESHOOTING
10.5 List of Error Codes
C05CH • The received request data of the SLMP
message is incorrect.
• The setting value of the communication setting
when the iQSS function is executed is out of
range.
• When the iQSS function is executed, the items
of communication setting which cannot be set
on the target device are set.
• When the iQSS function is executed, the
required setting items have not been set to the
target device.
• Correct the request data and send the SLMP message to the
Ethernet-equipped module again.
• Correct the setting details of when the iQSS function is executed,
and retry the operation.
C05DH The "Monitor Request" command is received
before the monitor registration is performed by the
"Monitor Registration/Clear" command of the
SLMP message.
Register the monitoring data using "Monitor Registration/Clear"
command and perform monitoring.
C05EH • The time between reception of the SLMP
request message by the Ethernet-equipped
module and the returned response from the
access destination exceeded the monitoring
timer value set in the SLMP command.
• An unresponsive command was sent to another
network station as the access destination. (If
this error does not cause any problems, it can
be ignored.)
• Increase the monitoring timer value.
• Check if the access destination is operating normally.
• Correct the network number or request destination station number.
• If the access destination is a module with a different network
number, check if the network number is not in use.
C05FH This request cannot be executed to the access
destination specified by the SLMP message.
Correct the access destination.
C060H The request details for bit devices of the SLMP
message is incorrect.
Correct the request details and send the SLMP message to the
Ethernet-equipped module again.
C061H • The request data length of the SLMP message
does not match 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 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 industrial switch 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.
C06FH The network number of request destination
specified by the SLMP request message is not
available for communications with the station
number 121 or larger.
• If the 3E or 4E frame is used at SLMP, check that there is no error
for the network number of the request destination and station
number.
• If the station number extension frame is used at SLMP, check that
there is no error for the network number of the request destination
and station number.
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 MELSEC iQ-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 a MELSEC iQ-R/Q/
QnACPU with the SLMP message 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 are
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.
