36.4 List of Error Codes
Error details and cause
• In the system where the CPU module is
connected to the request destination device over
Ethernet, the request path and the response path
of IP packets differ.
• When multiple CC-Link IE modules with the
same network number are connected in a
multiple CPU system, the CC-Link IE module
mounted on the lowest number slot is not set as a
controlled module of the CPU module that
transfers IP packets.
• When multiple CC-Link IE modules with the
same network number are connected in a single
or multiple CPU system, the station number of
the CC-Link IE module mounted on the lowest
number slot is not set as a relay station number
in routing parameter.
• The 3rd byte (network No.) of the IP address of
the request destination device is overlapping with
the 3rd byte of the IP address of the CPU module
connected to the request source device over
Ethernet.
• An IP address of a device on CC-Link IE network
or the CPU module is not specified.
• An error occurred in the access destination or the
relay station.
• The specified connection destination (request
destination module I/O number) is incorrect.
• The access destination CPU module has not
started up.
• The target CPU No. specified does not exist.
• The request is not addressed to the CPU module.
• The specified route is not supported by the
specified CPU module version.
• The communication target CPU module is not
mounted.
• A device mounted on the specified route does not
support communications.
• The specified connection destination (request
destination module I/O number) is not supported.
• There is not enough free space for storing the
result file in the target memory.
• Writing of the result file to the target memory has
not completed successfully because the SD
memory card is write-protected.
• Writing of the result file to the target memory has
not completed successfully because the folder/
file structure is incorrect.
• The SD memory card was removed while the
data logging function was being executed (data
logging status: Waiting RUN Not collected,
Waiting to establish collection conditions Not
collected, Waiting start Not collected, Pause,
Collecting, Waiting trigger Collecting before
trigger, Collecting after trigger, or Saving in
progress). Or, writing to the SD memory card has
not completed successfully.
• The number of files in the root directory and
subdirectory in the target memory exceeded the
limit.
• During auto logging, a data logging was not
registered due to a registration failure of the data
logging with another setting number.
Action
• Correct the routing parameter setting so that IP packets
travel the same path for both request and response
transmission.
• When multiple CC-Link IE modules with the same network
number are connected in a multiple CPU system, set the
module mounted on the lowest number slot as a controlled
module that transfers IP packets.
• When multiple CC-Link IE modules with the same network
number are connected in a single or multiple CPU system,
set the station number of the module mounted on the lowest
number slot as a relay station number in routing parameter.
• Check and correct the IP address settings of the CPU
module.
• Check and correct the IP address of the request destination
device.
• Specify an IP address of a device on CC-Link IE network or
the CPU module.
• Check the error occurred in the specified access destination
or the relay station, and take an action.
• Check the connection destination (request destination
module I/O number or PC number) in the request data of
SLMP/MC protocol.
• Check the stop error, and take an action.
• Check and correct the target CPU No.
• Perform operation for the module that can execute the
specified function.
• Check whether the specified route is supported or not.
• Check the mounting status of the CPU module.
• Check the stop error, and take an action.
• An invalid value is set as the start I/O number of the
connection target module. Set the start I/O number of the
target module correctly, and retry data communications.
• Increase the free space, and create the result file again.
• Unlock the write protect switch of the SD memory card, and
write the result file again.
• Check that the target memory is broken.
• Check that the folder or file to be used in the target memory
is deleted.
• Insert the SD memory card and execute the function again.
• Replace the SD memory card and execute the function
again.
• Increase the free space of the drive (memory), and execute
the function again.
• Delete files in the drive (memory), and execute the function
again.
• Clear the error, and start auto logging.
