Always outputs 'MDLB' as file identification.
Outputs 1 as the file version.
Outputs the file type.
1: Continuous/trigger logging
2: Event logging
Outputs the module model name which output the binary file.
Outputs 'QD81DL96' in the first 8 bytes, packed with 0x00 in the second 8 bytes.
Outputs the size of the header portion.
Outputs the size of 1 record.
For the data which can be selected to output, outputs information on whether they
are being output.

1: Outputs trigger flag
0: Does not output trigger flag
Outputs the logging data count configured in logging.
Outputs the total size of the data information size (2 bytes) and each of the sizes of
data length (10), data type (11), data name (12) per logging data.
Outputs the data length of logging data.
(If the data type is bit type, outputs 1 byte.)
Matched to the data type specified with output format, outputs the following values.
0: Bit
1: Signed integer
2: Unsigned integer
3: Float
4: BCD
5: String
6: Raw
Outputs the logging data name specified with the settings in ASCII code.
Outputs flags to identify the start and end of records.
Matched to the start/end of records, outputs the following constant values.
0xFF: Record start
0xFF: Record end
Outputs the number of elapsed seconds from January 1st 1970.
Outputs the remainder of time which is less than a second from the number of
elapsed seconds from January 1st 1970 in nanoseconds.
Outputs a numerical value starting from 1 incremented in ascending order.
When the value exceeds the upper limit of 4294967295, it is returned to 0 and
increments again in the range of 0 to 4294967295.
When missing sampling data occurs, the index is renumbered again from 1.
