Clearing of record

The load profile record can be cleared with

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.

The load profile record can be configured with the PCM600 or any tool supporting

the IEC 61850 standard.

The load profile record can be enabled or disabled with the

the Configuration/Load Profile Record menu.

Any demand output can be connected to any of the quantity channels of the load

profile record. The mapping is done in Application Configuration in PCM600.
