Oscillography, Events, and SER
Sequential Events Recorder (SER)
To clear all SER data from all serial ports, use the SER CA or SER RA
command, available only from Access Levels P, A, O, and 2. This procedure
would normally be used after relay commissioning or testing.
Use an ASCII terminal or
ACSELERATOR QuickSet to examine SER records.
You can use the SER command to view the SER report by date, date range,
SER number, or SER number range. The relay labels each new SER record
with a unique number.
You can retrieve SER records with
ACSELERATOR QuickSet. The HMI >
Meter and Control menu item gives you the SER report. The latest 200 SER
events are viewable on the front-panel display through the front-panel
EVENTS
MENU
.
CSER
The relay outputs a Compressed ASCII SER report for SCADA and other
automation applications. Issue the CSE command to view the Compressed
ASCII SER report. A sample of the SER report appears in Figure 8.19; this is
a comma-delimited ASCII file. The relay appends a four-digit hex checksum
at the end of the lines in the Compressed ASCII report.
Items included in the Compressed ASCII SER report are similar to the SER
report, although the relay reports the items in a special order. For the purpose
of improving products and services, SEL sometimes changes the items and
item order.

a
The parameters m and n indicate SER numbers that the relay assigns at each SER trigger.
Description
SER Return the 20 most recent records from the SER, with the oldest
(highest number) at the top of the list and the most recent (low-
est number) at the bottom of the list.
SER k Return the k most recent records from the SER, with the oldest
(highest number) at the top of the list and the most recent (low-
est number) at the bottom of the list.
SER m n Return the SER records from m to n.
If m is greater than n, records appear with the oldest (highest
number) at the top of the list and the most recent (lowest
number) at the bottom of the list.
If m is less than n, records appear with the most recent (low-
est number) at the top of the list and the oldest (highest num-
ber) at the bottom of the list.
SER date1
b
b
Use the same date format as Global setting DATE_F.
Return the SER records on date date1.
SER date1 date2 Return the SER records from date1 at the top of the list to date2
at the bottom of the list.
SER C and SER R Clear SER records on the present port.
SER CA and SER RA Clear SER data for all ports.
SER CV and SER RV Clear viewed SER records on the present port.
SER D List chattering SER elements that the relay is removing from
the SER records.
