ending character is read, the reading of the characters stops, and whether the
file name is legal is checked. The characters which can be used to constitute a
file name are A~Z, a~z, and 0~9. Besides, the file name extension depends on
the file format. The file which is created is in the default folder. If the file name is
"Test1", the characters are written into the devices as follows.

The default folder path:
Model name
AHCPU530-RS2
AHCPU530-EN
AHCPU530-EN/RM
AHCPU533-EN

16#005F
16#0060
16#0061
16#0062
16#0063

4. If the format of the file into which the data is written is 0, the format of the file from which the
data is read is 0. Otherwise, the data can not be read, and SM453 is ON. The same applies to
the other file formats.
Folder path
PLC CARD\AH500\UserProg
If the file format is 0, 1, 3, or 5, the unit of the value is the word. If the
file format is 2, 4, or 6, the unit of the value is the double word.
If the function option is 0, S
If the function option is 1, the data which is written into the memory
card replaces the values in the file starting from the value indicated by
the value in S .

If an error occurs during the operation of the memory card, the flag is
ON. If the flag is ON, users have to reset it to OFF. The error code is
stored in SR453.
An error occurs when the memory card is initialized.
The path is incorrect, or the file does not exist.
The default folder can not be created.
The memory space is insufficient.
The memory card is write protected.
An error occurs when the data is written into the file.
