Figure 9.1 Example Event Summary
The latest 80 event summaries are stored in nonvolatile memory and are
accessed by the HISTORY command. The HIS C command clears the event
summaries and corresponding full-length standard event reports from
nonvolatile memory. See HIS (History of Events) on page 7.19 and HIS C
(Clear History and Events) on page 7.19 for more information.
Event Type
The Event: field shows the event type. The possible event types and their
descriptions are shown in Table 9.1. Note the correspondence to the preceding
event report triggering conditions (see Standard Event Report Triggering on
page 9.2).
The order of precedence for listing the event type in the summary is:
TRIP,
CLOSE, ER, PULSE, TRIG (as implied by Table 9.1). If more than one type of
report trigger occurs within the same report period, the type of highest
precedence will be shown in the
Event: field of the report summary.
Targets
The target field shows all front-panel targets that were illuminated at the end
of the triggered event report. The targets include:
TRIP, INST, 87-1, 87-2,
87-3, 50, 51, A, B, C, N, W1, W2, W3, and W4.
NOTE: SEL-387-0 firmware versions
R100–R105 display 99 event
summaries. SEL-387-6 firmware
versions R304 and R405 display 40
event summaries. All other firmware
versions display 80 event summaries.
