Error details
The specified command cannot be executed
because the data logging function is being
performed (i.e. logging, saving the logging data,
completing, on hold, or in error).
The number of stored files has exceeded the
value set in advance.
The number of stored files has reached to the
maximum.
Common setting file does not exist.
A data logging is being performed (logging in
execution, logging data are being saved,
completing, on hold, or in error) in the same file
storage destination.
• Data logging file transfer function settings are
mistaken.
• A data logging setting file is corrupt.
• A data logging file to be transferred was
deleted during transfer by file switching.
• Reading of a data logging file failed.
• A data logging file was accessed while the SD
memory card has been forcibly set to be
disabled.
• Since a file was switched before file transfer, a
new data logging file is saved.
• Since a file was switched during a retry, a new
data logging file is saved.
File transfer failed due to the stop operation of
file transfer.
A file transfer test was executed from another
CPU Module Logging Configuration Tool during
execution of a file transfer test.
The data logging setting for different
programmable controller series was registered.
The total buffer capacity for realtime monitor and
data logging exceeds the maximum limit.
Online change was executed during execution of
realtime monitor where a step number is
specified as a timing condition or trigger
condition.
Corrective action
Stop the data logging and then execute the
command.
The number of files stored in the storage
destination memory has exceeded the setting
value. Delete files or change the storage
destination and then register.
The number of stored files has reached to the
maximum of FFFFFFFF. Delete files or change the
storage destination and then register.
• Write the common settings to the target memory.
• Register the data logging to the memory where
the common settings are stored.
Stop the data logging destined for the same
storage and then register.
Alternatively, change the storage destination of the
file and then register.
• Check settings of the data logging file transfer
function.
• Write the settings using the CPU Module
Logging Configuration Tool.
• Correct "File switching timing" and "Number of
saved files" in the "Save" screen.
• Check that data logging files are not deleted
using the CPU Module Logging Configuration
Tool.
• Check that an SD memory card is inserted.
• When the SD memory card access control
switch is on the upper position, slide it down,
and check that the SD LED turns on.
• If the SD memory card has been forcibly
disabled, cancel the setting.
• Correct "File switching timing" in the "Save"
screen to reduce the frequency of file switching.
• Correct the number of sampled data and
"Sampling interval" in the "Sampling" screen to
reduce the number of sampled data.
• Correct the settings in the "CSV output" screen
to reduce the file size.
• Check connection with the FTP server.
Check that data logging is not started from the
CPU Module Logging Configuration Tool before file
transfer is completed.
Execute the file transfer test again after the
ongoing test is completed.
Set the data logging for the programmable
controller series used.
• Correct the buffer capacity so that the total
capacity for data logging and realtime monitor
does not exceed the maximum limit. To change
the buffer capacity for data logging, write the
changed data (common setting) to the CPU
module and start data logging again, or power
off and on or reset the CPU module to restore
the data logging function to the initial state.
• Stop the realtime monitor function, and restart
data logging.
After the online change processing has completed,
check the step number, and execute the realtime
monitor again.
