Sequential Events Recorder (SER)
The Sequential Events Recorder (SER) gives you detailed information on
relay states and relay element operation. The SER captures and time-tags state
changes of Relay Word bit elements and relay conditions. These conditions
include power-up, relay enable and disable, group changes, settings changes,
memory overflow, diagnostic restarts, and SER autoremoval/reinsertion. The
relay stores the latest 1000 SER entries to nonvolatile memory. Figure 8.18 is
a sample SER report.
The SER report contains the following:
➤ Standard report header
➢ Relay and terminal identification
➢ Date and time of report
➤ SER number
➤ SER date and time
➤ Relay element or condition
➤ Element state
Figure 8.18 Sample SER Report
In the SER report, the oldest information has the highest number. The newest
information is always
#1. When using a terminal you can order the positions
of the SER records in the SER report.
Viewing the SER
Report
The relay displays the SER records in ASCII and binary formats.
Access the SER report from the communications ports and communications
cards in Access Level 1 and higher. You can independently clear/reset already
viewed SER data at each communications port (with the SER CV or SER RV
command) so that users at other ports (SCADA, Engineering, for example)
can retrieve complete SER reports. The SER CV or SER RV command will
not clear any SER data that has been recorded, but not viewed, on a particular
serial port. To clear all SER data on a serial port, use the SER C or SER R
command.
