7.6 Reading/Writing Data Instructions
• An integral multiple of "Number of columns" should be specified for "Number of request write data".
Otherwise, numbers of columns will be apart.
• The last data is always followed by a line feed code. In addition mode, therefore, data is added starting from
the beginning of a new line.
• When data is added to the end of a file, columns are shifted if "Number of columns" is changed from the
previous writing.
• The following figures show an example of specifying "String (ASCII data)" for the execution/completion type.
Ex.
Writing data after converted to CSV format (string (ASCII data))
• Set 00H (NULL) in the end of the string in an element. When the number of bytes of the string is even, set
0000H (two bytes of NULL) in the next one word.
• The maximum number of characters in one element is 1999. If this maximum number is exceeded and 00H
(NULL) is not stored, characters of 2000th character and after are not written and the write processing shifts
to the next element.
• A maximum of 1023 elements can be written in a single instruction execution.
[Data to be written to a file]
(1) Data to be written
(2) File name
(3) Control data
