Section 9. Events and Diagnostics
associated with the event will be available. To view
either of these, highlight the event and click on
either the View Fault Data or Waveform button at
the top of the SOE screen.
The Fault Report screen consists of a table of all
circuit breakers in the system with the RMS current
recorded by each circuit breaker's Messenger in
the half-cycle just before the event is shown for
each circuit breaker.
The SOE configuration screen can be opened by
clicking the Preferences button at the top of the SOE
window. The options here allow you to customize the
information retained and displayed to meet your
needs. The following configurations can be selected:
• Events Filter – Select which events are displayed
in the SOE. The filtering enables the user to limit
the types of events displayed by checking the
desired boxes. Events not selected for display
are still maintained in nonvolatile memory. These
can be viewed at any time by selecting the
appropriate type of event in the filtering list. The
user can filter by Event Category. Each type of
event is categorized by severity (Attention, Caution,
Trip, Alarm, Other), or you can select All categories
to be shown. There are also filters to select HMI
and CPU events and a specified date range.
• Protect vs. Overwrite – In Protect mode, the event
logger stops recording events if the maximum
size of the daily log is reached. In Overwrite mode,
the oldest events are overwritten on a FIFO basis,
if the maximum size of the daily log is reached.
Thus, the newest log information is always available
in the log.

• Event Log Size – This specifies the maximum size
of the daily log.
• Maximum Fault Reports – This specifies the max-
imum number of Fault Reports the HMI retrieves
and stores in a given day.
• Retention Days – The number of days event
records are retained before automatic deletion
to manage hard drive space.
Waveform Capture
All waveform captures are performed for the entire
Entellisys system . This means that all available
channels configured for recording are recorded
simultaneously for each waveform capture. The
following channels at each point are recorded:

• Command (Control) Transitions – Open, Close,
and Trip
• Status (Operation) Transitions – Open, Closed,
Spring Charge, Analog IOC, Backup Trip
Waveforms are captured by both internal and
external Entellisys system circumstances. Waveforms
for every circuit breaker in the system are captured
by the following conditions:
• Any protective relay (including overcurrent)
alarm reaches its alarm set point
• Any protective relay (including overcurrent) trip
reaches its trip set point
• Any circuit breaker operation (open, close, trip)
initiated from the HMI
• A specified FlexLogic virtual output operates. All
