4C0FH Data logging
function error
• The program file or global label setting file was changed
while the data logging function specifying the label (global
label or local label) as the collection start condition, data
collection target, 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).
• Do not change the program file or global label setting file
while the data logging function specifying the label (global
label or local label) 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 specifying the label (global label or
local label).
• Check and correct the setting of SD940 (Stop direction at file
change on label specification), and execute the function
again.
4C10H CPU module
data backup/
restoration
function error
• 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.
• 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.
4C11H CPU module
data backup/
restoration
function error
• An SD memory card is not inserted.
• An SD memory card is disabled by SM606 (SD memory card
forced disable instruction).
• Insert or re-insert an SD memory card, and execute the
function again.
• Enable the SD memory card operation, and execute the
function again.
4C12H CPU module
data backup/
restoration
function error
• Reading/writing of data from/to an SD memory card
completed with an error.
• 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.
4C13H CPU module
data backup/
restoration
function error
• Reading/writing of data from/to the CPU built-in memory
completed with an error.
• 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.
4C14H CPU module
data backup/
restoration
function 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.
• Delete file passwords, and execute the CPU module data
backup/restoration function.
4C15H CPU module
data backup/
restoration
function error
• The function that cannot be executed simultaneously with
the CPU module data backup/restoration function, such as
the file transfer function (FTP), iQ Sensor Solution data
backup/restoration function, and IP address change
function, is being executed.
• The CPU module data backup/restoration function is
executed when the following functions are being executed.
Online program change
File transfer function (FTP server)
• Execute the function again after a while.
4C16H CPU module
data backup/
restoration
function error
• The automatic backup setting by specification of day and
time is turned on while the setting value (automatic backup
date and time) are out of range.
• The automatic backup setting by specification of time and
day of the week is turned on while the setting value
(automatic backup time and day of the week) are out of
range.
• Review the setting value (automatic backup date and time)
and turn on the automatic backup setting by specification of
day and time.
• Review the setting value (automatic backup time and day of
the week) and turn on the automatic backup setting by
s
pecification of time and day of the week.
4C17H CPU module
data backup/
restoration
function error
• The model of the restoration target CPU module differs from
the model of the backup source CPU module.
• Execute the data restoration function to the CPU module
whose model is the same as that of the backup source CPU
module.
4C18H CPU module
data backup/
restoration
function error
• Data was restored while the operating status of the CPU
module is in RUN or PAUSE.
• Change the operating status of the CPU module to STOP,
and execute the function again.
