<Data type information row>
The data type for each column is displayed. This information is output in the following format: (Data type)[(Additional
information)].
Ex.
The size of the data type information row is determined by the following equation when data logging of 128 points of data
(signed 16-bit integer, decimal format) is performed (The following sections in the "Output" window are set to be output: "Date"
(the output format is YYYY/MM/DD hh:mm:ss.sss), "Data sampling interval", and "Index").
(8 + 25) (date column) + 8 (data collection interval column) + 5 (index column) + (5 + 7)  128 (data column) + 132 (the
number of commas) + 2 (CR + LF)
= 1716 bytes
<Data name row>
The data name for each column is displayed.
Ex.
The size of the data name row is determined by the following equation when data logging of 128 data points from D100 to
D227 is performed (The following sections in the "Output" window are set to be output: "Date", "Data sampling interval", and
"Index").
4 (date column) + 12 (data collection interval column) + 5 (index column) + (4  128) (data column) + 132 (the number of
commas) + 2 (CR + LF)
= 667 bytes
