■When reading data after converted to CSV format
• Elements in the CSV format file (cells in Excel
• If the extension of the target file is omitted, the extension will be ".CSV".
• If the specified file does not exist, an error occurs.
• If the position is specified exceeding the existing file size, 0 point of data is read and the processing completes successfully.
• The number of data specified by (d1)+2 is read from the beginning of the file. If the last data in the file is read before
reaching to the number specified, only the available number of data is read.
• When the number of columns is set to 0, the data are read by ignoring the rows in the CSV format file.
• The string data in the CSV file and the value stored in the device after it is read are determined by the execution/completion
type.
Execution/completion type
0100H: Decimal (16-bit data)
0110H: Decimal (32-bit data)
0120H: Hexadecimal (16-bit data)
0121H: Hexadecimal (32-bit data)
0130H: String (ASCII data)

NULL (00H) is added to the end of the string.
When the number of bytes of the string in the
CSV file is even, 0000H is stored in the next
one word.
When the string in the CSV file contains 00H,
it is ignored.
If the number of characters in one element
exceeds 1999, characters until the 1999th
character are read as one element. The
2000th character and after are not read and
the next element is read.
