Memory Allocation for Log Files
Each file in the power and energy meter has a maximum memory size. Memory is not
shared between the different logs, so reducing the number of values recorded in one log
will not allow more values to be stored in different log. The following table lists the
memory allocated to each log.
Alarm Log
By default, the power and energy meter can log the occurrence of any alarm condition.
Each time an alarm occurs it is entered into the alarm log. The alarm log in the power and
energy meter stores the pickup and dropout points of alarms along with the date and time
associated with these alarms. With PowerLogic software, user can view and save the
alarm log to disk, and reset the alarm log to clear the data out of the power and energy
meter’s memory.
Alarm Log Storage
The power and energy meter stores alarm log data in non-volatile memory. The size of
the alarm log is fixed at 40 records.
