Status of logging
The status of logging in progress can be checked by System.LoggingRef[1..10].Md.LoggingStatus,
System.LoggingRef[1..10].Md.TriggerStatus[1..32], System.LoggingRef[1..10].Md.Triggered, and
System.LoggingRef[1..10].Md.SaveStatus.
The following explains the operation at trigger logging when Data = 100 is set for a "Trigger condition", and 2 is set for a
"Number of trigger logging".

It turns TRUE while trigger condition is processed for System.LoggingRef[1..10].Md.TriggerStatus[1..32], and after trigger
condition is processed for System.LoggingRef[1..10].Md.Triggered. After the completion of collecting the number of records
set to the "number of records after trigger", they both returns to FALSE.
After the completion of saving files, it turns the state of System.LoggingRef[1..10].Md.SaveStatus as follows.
3: FullySaved
• When the number of records specified during continuous logging "Number of file switching records" is all saved in a file.
• When the number of records specified during trigger logging "Number of records after trigger" is all saved in a file, and
when the files are saved at the number of specified times at "Number of trigger logging".
2: Saved
• When the file is saved with the state that does not meet the condition of "3: FullySaved".
However, after the status becomes "2: Saved" or "3: FullySaved", the status moves to be "0: UnSave" immediately if the
logging is in progress.
