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 cur-
rently.
The specified device name cannot be handled.
The specified device No. is outside the range.
There is a mistake in the specified device qualifi-
cation.
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

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.
Do not access the specified file.
Forcibly execute the request, or make the request again after
the processing from the other peripheral device is com-
pleted.

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 speci-
fied drive memory.
After backing up the data in the CPU module, execute pro-
grammable 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 name.
• 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 mod-
