<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", "Execution step No.", "Execution program name
or execution program No.", and "Index").
(16 + 50)(date column) + 16(data collection interval column) + 16(execution step No. column) + 22(execution program
number column) + 24(execution program name column) + 10(index column) + (10 + 14)  128(data column) + 264(the
number of tabs) + 4(CR + LF)
= 3494 bytes
<Data name row>
