generated by both internal logical signals and binary input channels. The internal
signals are time-tagged in the main processor module, while the binary input channels
are time-tagged directly in each I/O module. The events are collected during the total
recording time (pre-, post-fault and limit time), and are stored in the disturbance report
flash memory at the end of each recording.
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 , indications and event recorder function.
The event record is stored as a part of the disturbance report information and managed
via the local HMI or PCM600.
Events can not be read from the IED if more than one user is accessing
the IED simultaneously.

Event list
14.7.1
Functionality
Continuous event-logging is useful for monitoring the system from an overview
perspective and is a complement to specific disturbance recorder functions.
The event list logs all binary input signals connected to the Disturbance recorder
function. The list may contain up to 1000 time-tagged events stored in a ring-buffer.
14.7.2
Function block
The Event list has no function block of it’s own.
