3 WHEN COMMUNICATING USING THE QnA COMPATIBLE 3E/3C/4C FRAMES OR 4E FRAME
(r) File lock mode: For QnACPU files
This flag designates whether or not a file lock is to be forcefully cleared in
order to allow access to the designated file from another device.
1) Data communication in ASCII code
The value shown below is converted to a 4-digit (hexadecimal) ASCII
code and sequentially transmitted beginning from the most significant
digit "0".
2) Data communication in binary code
The 2-byte value shown below is transmitted from the low byte (L: bits
0 to 7).
3) The values and options that can be designated for the file lock mode
are as follows; other values cannot be designated.
Designated value
0000 Normally execute file lock cancel.
H
0002 Forcefully execute file lock cancel.

4) When a file lock cancel instruction is issued for a designated file, the
normal execution and forced execution differ as follows.
• Normal execution
The file lock cannot be canceled when another device has
registered the file lock.
When the file lock cancel is requested, an error occurs and an
abnormal response is returned.
• Forced execution
The file lock is forcefully canceled even if another device registered
the file lock.
Use the forced execution function when a file lock cannot be
canceled because of problems in the device that registered the file
lock.
(s) Copy mode: For QnACPU files
This flag designates whether or not to copy the last update time and data of
the source file to the target file at the completion of copying.
When the date and time are not copied, the QnACPU management time
when a new file was created, remains unchanged.
1) Data communication in ASCII code
The value shown below is converted to a 4-digit (hexadecimal) ASCII
code and sequentially transmitted beginning from the most significant
byte.
2) Data communication in binary code
The 2-byte value shown below is transmitted from the low byte (L: bits
0 to 7).
3) The values and options that can be designated for copy mode are as
follows.
Designated value
Do not copy the date and time the source file was last updated at the completion of
