Appendix 9 Data Logging File Format
Description
Always outputs 'MRLB' for file identification.
Outputs '1' as the file version.
Outputs the file type.
1: Continuous logging/trigger logging
2: Event logging
Outputs the module model name which output the binary file.
Outputs 'RD81DL96' in the first 8 bytes, packed with 0x00 in the second 8 bytes.
Outputs the size of a header part.
Outputs the size of 1 record.
Outputs the settings for the respective data which can be selected to output.

1: Outputs trigger flag
0: Does not output trigger flag
Outputs the number of pieces of logging data configured in the logging setting.
Outputs the total size of the data information size (2 bytes) and each of the sizes of (10) data length, (11) data type,
(12) data name per logging data.
Outputs the data length of logging data.
If the data type is bit type, outputs 1 byte.
Outputs the following values according to the data type specified in output format.
0: Bit
1: Signed integer
2: Unsigned integer
3: Float
4: BCD
5: String
6: Raw
■When other than "Value" is specified in output value using trigger logging, the data type is as follows:
• When "Number of times" or "Total number of times" is specified
2: Unsigned integer
• When "Time" or "Total time" is specified
3: Float
Outputs the logging data name specified in setting in Unicode.
Outputs flags to identify the start and end of records.
Outputs the following constant values according to the start/end of records.
0xFF: Record start
0xFE: 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 will be renumbered from 1.
