SEL-411L-R117-V2-Z009002-D20151029
SEL-411L-1-R117-V2-Z009002-D20151029
➤ Modified the Ethernet port initialization to prevent loss of
communication to the serial port when certain settings are sent
to the relay immediately following a power cycle.

SEL-411L-R117-V1-Z009002-D20150716
SEL-411L-1-R117-V1-Z009002-D20150716
➤ Improvements for manufacturability. 20150716
SEL-411L-R117-V0-Z009002-D20150626
SEL-411L-1-R117-V0-Z009002-D20150626
➤ Enhanced the Out-of-Step blocking logic to be more dependable
during single-pole open conditions.
➤ Added supervision to the quadrilateral phase- and ground-
distance elements for unusual unbalanced load conditions.
➤ Modified code to maintain VMEMC setting value during an upgrade.
➤ Added polarization voltage validation check to supervise
quadrilateral phase-distance elements.
➤ Added the option to change settings groups with IEC 61850.
➤ Added the LPHD.Sim logical node so the relay will accept
GOOSE messages with the test flag asserted.
➤ Added support for the stSeld attribute in IEC 61850 SBO controls.
➤ Added total energy analog quantities to the DNP3 analog input
reference map, and the imported and exported energy scaled and
labeled to KW to the binary counter reference data map.
20150626
➤ Added Isolated IP mode (NETMODE = ISOLATEIP) which
permits IEC 61850 GOOSE messages on two ports, but restricts
IP traffic to just one port.
➤ Added pulsed remote bits in Automation SELOGIC.
➤ Added FRQST and PMLEGCY settings to maintain backward
settings compatibility.
➤ Added aliasing capability for the phasors, analogs, and digitals
in the synchrophasor data.
➤ Enhanced the report time records to save the active UTC offset
(UTCOFF) value with each report. Now, when the relay collects
a report, it assigns the time stamp based on the UTC time and
the UTCOFF value at the time the relay stores the report.
➤ Removed the port uniqueness requirements for the PMOUDP1
and PMOUDP2 settings.
➤ Enhanced the embedded HTTP server user interface to be
consistent with other SEL relays.
➤ Improved the Sequential Events Recorder (SER) resolution to
0.5 ms for level sensitive contact inputs.
➤ Modified the relay to support MMS file transfer service even if
the relay contains an invalid CID file.
➤ Modified the embedded HTTP server web access to always
require a valid relay Access Level 1 (ACC) password.
➤ Updated the maximum and minimum line metering data
(MET M commands) to display local time for all data.
➤ Reset the port timeout on transmitted Telnet messages.
➤ Updated the profile and compressed profile commands (PRO
and CPRO, respectively) to display the available analog signal
profiling records regardless of the state of the signal profile
enable (SPEN) setting.
