In case of overlapping recordings, due to PostRetrig = On and a new trig signal
appears during post-fault time, events will be saved in both recording files.
The name of the binary input signal that appears in the event recording is the user-
defined name assigned when configuring the IED. The same name is used in the
disturbance recorder function (DR), indications (IND) and event recorder function
(ER).
The event record is stored as a part of the disturbance report information (ER, DR,
IND, TVR and FL) and managed via the local HMI or PCM600.

Function block

The Event recorder has no function block of it's own. It is included in the
DRPRDRE block and uses information from the BxRBDR block.

Input signals

The Event recorder function logs the same binary input signals as the Disturbance
report function.

Trip value recorder

Introduction

Information about the pre-fault and fault values for currents and voltages are vital
for the disturbance evaluation.
The Trip value recorder calculates the values of all selected analog input signals
connected to the Disturbance report function. The result is magnitude and phase
angle before and during the fault for each analog input signal.
The trip value recorder information is available for the disturbances locally in the
IED.
