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",
"Execution step No.", "Execution program name or execution program No.", and "Index").
28(date column) + 24(data collection interval column) + 16(execution step No. column) + 22(execution program number
column) + 24(execution program name column) + 10(index column) + (6  128)(data column) + 264(the number of tabs) +
4(CR + LF)
= 1138 bytes
<Device comment row>
The device comment row for each column is displayed.

Ex.
The size of the device comment 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" (the output format is YYYY/
MM/DD hh:mm:ss.sss), "Data sampling interval", "Execution step No.", "Execution program name or execution program No.",
"Index", and "Device comment output" (only for devices from D200 to D227)).
