In addition to the "Value Limit", Accumulation can be reset by a user-defined "Reset Time" in minutes. A non-zero number defines the reset time.
If the number less than 1440, 1 day, the reset time will be aligned to midnight, otherwise it will be reset on the every M day from the start of the month, where M=reset time/1440.
All the trend/ODBC log data will be recorded before reset, if the record time matches with reset time.
Reset time example:
"Reset Minutes" Execution time
15 0:00, 0:15, 0:30, 0:45, 1:00, 1:15......
60 0:00, 1:00, 2:00...
90 0:00, 1:30, 3:00...
1440 0:00 every day
3000 0:00 on the 2nd, 4'th, 6'th, 8'th... day of each month. (3000/1440 = 2 ).
The "Value Limit" is still in effect. The Acc. point will be reset whenever a time or value limit condition meet.
