Clearing of record

The load profile record can be cleared with Reset load profile rec via HMI,
communication or the ACT input in PCM600. Clearing of the record is allowed only
on the engineer and administrator authorization levels.
The load profile record is automatically cleared if the quantity selection parameters
are changed or any other parameter which affects the content of the COMTRADE
configuration file is changed. Also, if data source for selected quantity is removed, for
example, with ACT, the load profile recorder stops recording and previously collected
data are cleared.

Configuration

The load profile record can be configured with the PCM600 tool or any tool
supporting the IEC 61850 standard.
The load profile record can be enabled or disabled with the Operation setting under the
Configuration/Load Profile Record menu.
Each protection relay can be mapped to each of the quantity channels of the load
profile record. The mapping is done with the Quantity selection setting of the
corresponding quantity channel.
The IP number of the protection relay and the content of the Bay name
setting are both included in the COMTRADE configuration file for
identification purposes.
The memory consumption of load profile record is supervised, and indicated with two
signals MEM_WARN and MEM_ALARM, which could be used to notify the customer that
recording should be backlogged by reading the recorded data from the protection
relay. The levels for MEM_WARN and MEM_ALARM are set by two parameters
Mem.warn level and Mem. Alarm level.
