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.

Event list

12.7.1

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 every status change of 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.
12.7.2

Function block

The Event list has no function block of its own.

Signals

12.7.3.1

Input signals

The Event list logs the same binary input signals as configured for the Disturbance report function.
12.7.4

Operation principle

When a binary signal, connected to the disturbance report function, changes status, the event list
function stores input name, status and time in the event list in chronological order. The list can
