Error details and cause
The specified file is being accessed.
The file name is specified in a wrong method.
The file system of the specified drive (memory) is
logically corrupted.
The specified drive (memory) does not have
continuous free space. (The free space for file is
sufficient but the continuous free space is
insufficient.)
The file size is larger than the following:
• the value to be acquired when 2 bytes are
subtracted from 4G bytes.
The request cannot be executed because the
operation is prohibited by the system.
The specified file is already being manipulated from
the engineering tool.
An attempt was made to initialize the drive (memory)
being used.
There are no data written to the data memory.
The request cannot be executed because the
specified module is being changed online.
The remote head module does not support for the
specified method of online module change.
The following operations is requested to the remote
head module in the standby system, but cannot be
performed because they are not supported.
• System switching
Data communications cannot be performed with the
other system because of any of the following
reasons:
• The remote head module of the other system is in
a reset state.
• Hardware failure of the remote head module of the
other system
The request cannot be executed because a
moderate or major error has occurred in the remote
head module of the standby system.
The request cannot be executed because the
operating status of the remote head module in the
control system differs from that of the remote head
module in the standby system.
The request cannot be executed because the
systems are being switched.
The request cannot be executed because the
memory copy function is being executed.
Data communications cannot be performed with the
system specified as a connection destination
(request destination module I/O number) because of
either of the following reasons:
• The request was issued during the system
switching processing.
• The system specified as a connection destination
(request destination module I/O number) does not
exist.
Action
Execute again after a while.
Execute again after checking the file name.
• The file information data may be corrupted.
• Back up data in the remote head module, and
then initialize the memory.
Execute again after deleting unnecessary files.
Specify a smaller value for the file size when
creating a file or changing the file size. Alternatively,
divide the file so that each file size is smaller.
Do not request the file operation because it is
prohibited by the system.
Execute again after the currently performed
operation is completed.
Stop all accesses to the specified drive (memory),
and execute the request again.
Write all the required files to the programmable
controller.
• Execute the request again after the online module
change processing ends.
• If the online module change operation cannot be
completed, power off the system, and change the
module.
Execute the online module change by using the
method that can be used in the current system
configuration.
Perform these operations to the remote head
module in the control system.
Check that there is no error or failure in the remote
head module of the other system, and perform a
retry. If the same error code is displayed again, the
possible cause is a hardware failure of the remote
head module. Please consult your local Mitsubishi
representative.
Check the moderate or major error, eliminate the
error cause, and then execute the request again.
Match the operating status of the remote head
module between the systems, and execute the
request again.
Execute the request again after the system
switching processing ends.
Execute the request again after the memory copy
processing ends. The completion status can be
checked in the following special relay areas.
• SM1654 (Memory copy being executed): Off
• SM1655 (Memory copy completion): On
Check the following, and execute the request again.
• The system switching processing has completed.
• The redundant system has started up
successfully.
