Firmware and Manual Versions
Firmware
➤ Made all of the INxxx and OUTxxx Relay Word bits visible
regardless of hardware configuration.
➤ Revised the firmware to display the alias Relay Word bits names
instead of "Unused" in the COMTRADE .cfg file.
➤ Changed the 81UVSP default setting from 56 V to 85 V.
➤ Added third pass-band filter to synchrophasor filter selections.
➤ Added Traveling Wave peak arrival times to DNP map and IEC
61850.
➤ Enhanced synchrophasor digital and analog mapping.
➤ Added phase-phase current-only fault identification Relay Word
bits.
➤ Increased number of binary outputs to 100 in custom DNP map.
➤ Implemented multiple updates to the DNP3 control point
operations.
➤ Made frequency elements immune to TRIP condition.

➤ Manual Update only (see Table A.5) 20150126
SEL-411L-R116-V0-Z008002-D20141224
SEL-411L-1-R116-V0-Z008002-D20141224
➤ Added support of 87L line current differential protection using
Ethernet communications.
➤ Added DNP reference FFROM to indicate the fault location
reference terminal.
➤ Enhanced G.703 protocol to either produce its own clock signal
or recover an external clock signal to synchronize its transmit
rate. Setting 87TIMC was added to control this behavior.

SEL-411L-R115-V0-Z007002-D20140912
SEL-411L-1-R115-V0-Z007002-D20140912
➤ Changed the 87L blocking function to include group setting
E87L = N. This prevents inadvertent operation of the
differential element when E87L is changed to N at one terminal.
➤ Improved 87L channel synchronization to prevent misalignment
on C37.94 and EIA-422 serial cards that have not been
synchronized to a multiplexer which provides a correct external
clock signal.
➤ Improved warm start initialization to prevent inadvertent
operation of the differential element during a settings change or
group switch while load currents are applied.

SEL-411L-R114-V0-Z007002-D20140429
SEL-411L-1-R114-V0-Z007002-D20140429
Note: Firmware versions R112 and R113 did
not production release.
➤ Added setting EFID to enable/disable Fault Identification Logic.
➤ Added setting EWDSEC to enable/disable the 87L Watchdog
counters for testing purposes.
➤ Modified how 10-cycle analog quantities are initialized.
➤ Added MIRRORED BITS Group Protocol Setting (MBG).
➤ Improved 87L channel delay calculation to reduce channel
alarms when the channel delay is constantly changing.
➤ Changed the 87L time fallback modes to ensure proper fallback
to channel-based synchronization mode in the presence of
intermittent IRIG signals.
➤ Changed the 87L time fallback modes to ensure proper fallback
and operation during a settings change. In previous firmware,
the relay could lose channel synchronization with other relays
when it was set to time-based synchronization (87CHnSN = T)
and while it was in time fallback to channel-based
synchronization mode and a setting change occurred.
