Retrieving Event Reports

Use the serial port EVENT command to retrieve
event reports. There are several options for
customizing the report format. The general
command format is shown in Table 9.2. Table 9.3
lists example EVE commands.
Event n R
Where:
Event number (1 – 14). Defaults to 1 if not listed,
where 1 is the most recent event. If you request an
n
event that does not exist, the relay responds Invalid
Event.
Specifies the unfiltered (raw) event report. Displays 16
R
samples per cycle.
Table 9.2 Event Commands
Serial Port
Command
Display the most recent event report at
EVE
1/4-cycle resolution.
Display the second event report at 1/4-cycle
EVE 2
resolution.
Display most recent report at 1/16-cycle
EVE R resolution; analog data are not digitally
filtered (raw).

The SIMPRO-100 Relay also provides a facility to
allow you to download event report data using
Modbus, protocol and the rear-panel serial port.

Description
9.5.3 Event Report Data Column
Definitions
The event report data is arranged in columns and
rows. Each column includes a single type of data
such as A-phase current samples or the state of
two output contacts. Each row displays the
measurements and results of a single instant in
time. Event reports you view using the EVENT
command contain four samples per power
system cycle. Raw event reports and the
compressed event format that the SIMPRO-PC
software uses to display oscillographic
information include data for 16 samples per
power system cycle. In event reports, time runs
down the page; first occurrences are shown at
the top of the page, final conditions at the bottom.
Events contain 3 cycles of pretrigger data and 12
cycles of posttrigger data to show the motor and
system conditions before, during, and after the
fault. Definitions and descriptions of the event
report data columns are shown in Table 9.4 and
Table 9.5.
9.5.3.1 Current & Voltage Columns
Table 9.4 summarizes the event report current
and voltage columns
Column

IA Current measured by channel IA (primary A)
IB Current measured by channel IB (primary A)
IC Current measured by channel IC (primary A)
IG Residual current (IA + IB + IC, primary A)
IN Current measured by channel IN (primary A)
VA or VAB Voltage measured by channel VA or VAB
(primary V)
VB or VBC Voltage measured by channel VB or VBC
(primary V)
VC or VCA Voltage measured by channel VC or
calculated from VAB and VBC (primary V)
