Error details and cause
• The online change function was executed while
the data logging function specifying the step
number as a sampling or trigger condition was
being executed (data logging status: RUN waiting
(no collection), Condition waiting (no collection),
Start waiting (no collection), Pause, Collecting,
Trigger waiting (collecting before trigger),
Collecting after trigger, or Saving the logging
data).
• System error
• A data logging is attempted to start with a data
storage memory that is different from the one for
the data logging already registered.
• A data logging file that is being transferred is
deleted.
• Reading from (an access to) a data logging file is
failed.
• The specified file does not exist. Or, the specified
subdirectory does not exist.
• The maximum allowable capacity is exceeded.
• The maximum allowable number of files is
exceeded.
• The upper limit of the backup folder number is
exceeded.
• The maximum length (255 characters) of the file
path is exceeded.
• An SD memory card is not inserted.
• The SD memory card is disabled by SM606 (SD
memory card forced disable instruction).
• Reading/writing of data from/to an SD memory
card completed with an error.
• Reading/writing of data from/to the CPU built-in
memory completed with an error.
• The CPU module data backup/restoration
function cannot be executed because a file
password is set to the data.
• Data was restored to the CPU module where the
same data with a file password has already been
stored.
• Any of the following functions that cannot be
executed simultaneously with the CPU module
data backup/restoration function is being
executed: the file transfer function (FTP), data
backup/restoration (iQ Sensor Solution function),
IP address change function, firmware update
function (via the engineering tool), memory copy
function, or online module change function.
• The CPU module data backup/restoration
function is executed when the following functions
are being executed.
 Online change
 File transfer function (FTP server)
Action
• Do not execute the online change function while the data
logging function specifying the step number is being
executed (data logging status: RUN waiting (no collection),
Condition waiting (no collection), Start waiting (no collection),
Pause, Collecting, Trigger waiting (collecting before trigger),
Collecting after trigger, or Saving the logging data).
• Stop the data logging function specifying the step number.
• Check the specified data, and write it to the CPU module
again.
• Check and correct the setting for the data logging to be
started.
• Check and correct the number of files to be saved in the file
switching setting.
• Check that the data logging file is not deleted.
• Check that an SD memory card is inserted.
• Check the file name and subdirectory name. Then, execute
the function again.
• Increase the free space of the SD memory card and CPU
module, and execute the function again.
• Delete files in the SD memory card and CPU module, and
execute the function again.
• Delete backup data in the SD memory card and CPU
module, and execute the function again.
• Check and correct the folder structure or folder/file names of
backup target data, and execute the data backup function
again.
• Insert or re-insert an SD memory card, and execute the
function again.
• Enable the SD memory card operation, and execute the
function again.
• Check that an SD memory card is inserted, and execute the
function again.
• Replace an SD memory card, and execute the function
again.
• The backup data may have been corrupted. Execute the data
restoration function using another backup data.
• Back up data in the CPU built-in memory, initialize the
memory, and write the data back to the original memory.
Then, execute the data backup/restoration function.
• The possible cause is a hardware failure of the restoration
target CPU module. Execute the data restoration function to
another CPU module.
• Delete file passwords, and execute the CPU module data
backup/restoration function.
• Execute the function again after a while.
