Application Firmware
Version and Date
Change
• Setting groups can be changed during the reclosing sequence by
monitoring the 79 shot counter.
• Changed the default settings for programmable variable names.
Defaults are now all set to generic variable names with state names of
TRUE or FALSE.
• Re-ordered the output of the S command to match the order of settings
as listed in the instruction manual, Appendix C.
2.41.00, 06/99 • Added Modbus full write functionality.
• Changed version format from x.xx to x.xx.xx.
• Added Transducer Network Lite Protocol (TNP Lite).
• Improved trip circuit monitor to allow use with ac trip voltage.
2.37, 11/98 • Increased the range of breaker duty I or I 2 accumulation from 2.17e7
to 4.2e7.
2.36, 09/98 • Added Distributed Network Protocol (DNP) 3.0 with limited read and
control functions.
2.31, 02/98 • Increase the range of the programmable 51 curve, A coefficient, from 0
- 100 to 0 - 600.
2.27, 01/98 • Improved 62 timer performance.
• Changed minimum breaker failure time from 100 ms to 50 ms.
• Added functionality to enable or disable targets for each protective
function.
• Added functionality to allow HMI Alarm Reset pushbutton to be used as
a logic variable (RSTKEY).
• Improved fault recording functions as follows:
o Phase, neutral, and negative-sequence currents are recorded
one cycle after the TRIP trigger logic becomes TRUE.
o Added programmable alarm for Fault Record Time Out and
changed the error readout to show N/A for this condition with
BREAKER OPERATE TIME and FAULT CLEARING TIME.
o Change the RF-TRIP to show RF=TRIG instead of SERIAL for
EVENT TYPE and FAULT TRIGGER.
o Second oscillographic record triggering point was changed from
when the TRIP trigger logic became TRUE, to when both PU
and LOGIC trigger logic became FALSE.
o Second oscillographic record was changed to record without a
gap between the first and second records during specific
conditions.
2.15, 05/97 • Initial release
