Schneider Electric PM5300 manual Memory Allocation for Log Files, Alarm Log Storage

PowerLogic™ PM5300 series user guide Chapter 8—Data Logs

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.

	Max. Records	Storage	Power and
Log Type			Energy Meter
	Stored	(Bytes)
			Model
Alarm Log	100	2,200	All models
Data Log	5760	256k	All models

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.
