The list can be configured to show oldest or newest events first with a setting on the
local HMI.
The sequential of events function runs continuously, in contrast to the event recorder
function, which is only active during a disturbance, and each event record is an integral
part of its associated DR.
The name of the binary signal that appears in the event recording is the user-defined
name assigned when the IED is configured. The same name is used in the disturbance
recorder function , indications and the event recorder function .
The sequential of events is stored and managed separate from the disturbance report
information.

Trip value recorder
Functionality
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.
The trip value recorder information is an integrated part of the disturbance record
(Comtrade file).
Function block
The Trip value recorder has no function block of it's own.
