8.2.3 Screen information
Figure 8.2-5 illustrates the structure about the ‘Event Recored1’ group, which can be shown
the latest event#1 at the top structure (line ○

). The lines ○
c
and ○
d
describes how an event
occurred for the event#1. Preceding event#2, event#3, etc. are shown below the event#1.
Similarly, the information about the ‘Event Record2’ and ‘Event Record3’ groups are displayed
on the IED screen.

8.2.4 Setup for the event recorder
Consider that a trip-command, which is denoted with Data ID ‘4A1001 8300001B6F’, should
be sorted into the ‘Event record1’ group. The settings [End of E.Record-1]=256 and [End of
E.Record-2]=512 have been made as default; hence, we may select it with the trigger#157 by
setting the [Trigger ID157]= ‘4A1001 8300001B6F’. Set On-OFF for the [Trigger Mode157],
because the pulse-train of the trip command should be recorded along the pick-up and drop-off
times. Remember that the preferred name for the Trigger ID157 should be set using the [Event
Name157].
