there is an error.
The file with the specified file name or file No.
does not exist.
The file name and file No. of the specified file
do not match.
The specified file cannot be handled by a user. Do not access the specified file.
The specified file is processing the request
from the other peripheral device.
The file password or drive keyword set to the
target drive (memory) must be specified.
The specified range exceeds the file range.
The same file already exists.
The specified file capacity cannot be obtained.
The specified file is abnormal.
The request contents cannot be executed in
the specified drive memory.
The requested operation cannot be executed
currently.
The specified device name cannot be handled. Check the specified device name.
The specified device No. is outside the range.
There is a mistake in the specified device
qualification.
The unusable device name
(TS,TC,SS,SC,CS,CC) must be specified in
MC protocol random reading, random writing
(word), monitor registeration and monitor
command.
Writing cannot be done because the specified
device is for system use.
Cannot be executed since the completion
device for the dedicated instruction cannot be
turned ON.
Corrective action
• Check the specified drive memory status.
• After backing up the data in the CPU module, execute
programmable controller memory format.
Check the specified file name and file No.
Delete the file and then recreate the file.
Forcibly execute the request, or make the request again
after the processing from the other peripheral device is
completed.
Make access after specifying the file password or drive
keyword set to the target drive (memory).
Check the specified range and access within that range.
Forcefully execute the request forcibly.
Or reexecute after changing the file name.
Revise the specified file contents.
Or reexecute after cleaning up and reorganizing the
specified drive memory.
After backing up the data in the CPU module, execute
programmable controller memory format.
Execute again after setting the CPU module to the STOP
status.
Execute programmable controller memory arrangement
to increase the continuous free space of the drive
(memory).
Execute again after a while.
• Check the specified device No.
• Check the device assignment parameters of the CPU
module.
• Check the specified device qualification method.
• Check the specified device name.
Do not write the data in the specified device, and do not
turn on or off.
Since the completion device for the target station CPU
module cannot be turned ON by the SREAD instruction/
SWRITE instruction, execute again after setting the
operating status of the target station CPU module to the
RUN status.
