Event recorder
Signals are generated in the logics of BIO modules etc. in the IED. The event recorder can
memory the generated signals as events. To operate the event recorder, the user should pick a
preferred signal as a trigger of the event recorder; the event recorder can have 768 triggers,
some of which have been set as a default. The user can group the triggers into three categories;
consequently, it is possible that a number of the events are divided depending on the degree of
the errors, the meaning of the operations, and the signals of relay elements, etc. The user can
also program how an event is to be detected. An event is recorded with millisecond accuracy.
The information are memorized until the number of the events reaching 1024; the oldest event
will be deleted when a new event appears.
8.2.1 Trigger signals
The event is memorized when the event recorder detects changing the trigger signal that is
connected with the logic signal; they are defined using settings [Trigger ID1] to [Trigger ID768].
Settings [End of E.Record-1] and [End of E.Record-2] are provided for grouping†; the user can
adjust the size of the ‘Event Record1’ group using the [End of E.Record-1]. The next ‘Event
Record2’ group is set with the [End of E.Record-2]. The remains are set for the ‘Event Record3’
group. Remember that the [Trigger ID1] etc. are required to set together with the [Event
Name1] etc.; user’s preferred names should be less than 18 letters.

Figure 8.2-1 Relation between function signals and triggers for Event record1
Figure 8.2-1 illustrates signals connected with triggers in the event recorder. For example,
‘SYS_CHG’ is connected with trigger#7 using the [Trigger ID7] and ‘FR_CLR’ is connected with
