UR Family Firmware 5.83 - Release Notes
15
R
IRIG-B clock synchronization to properly update time when time is set on Dec-31st of a leap year
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 6.01
Workaround: None
Description: If the date and time settings were provided to an UR devices on December 31st of a leap
year, the relay showed the “Maintenance Alert: IRIG-B error” and did not update its date and time. This FW
version ensures the relay’s date and time are properly updated regardless when these parameters are set
and the type of year.
GE tracking number: 601-8
C
Breaker and switch elements have been changed to ensure they show the right status when there is
no feedback from the breaker/switch auxiliary contacts and to comply with the IEC61850 standard
Products: B30, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 5.90
Workaround: None
Description: “Breaker” and “Switch” elements declare status depending on the breaker’s / Switch’s
auxiliary contact feedback (normally open and normally close contacts). This FW version introduces
changes to the Breaker and Switch elements logic that ensure the proper status indication when there is
no feedback from the auxiliary contacts (no DC voltage on both normally open and normally close
contacts). In addition, the logic related to both “Bad” and “Intermediate” status was modified to comply
with the IEC61850 standard (00 = ”intermediate”, 11 = “Bad”). For further information, see the UR device
instruction manual.
GE tracking number: 590-12
C
UR IEC6870-5-104 implementation has been changed to prevent slave devices from issuing start
request command
Products: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 5.72
Workaround: None
Description: IEC60870-5-104 determines that only master devices are to issue StartDT requests. UR relays
are 60870-5-104 slave devices and are not issue this request.
Previous FW versions allow UR devices to issue a StartDT request when receiving a connect request from
the IEC60870-5-104 master.
If the IEC60870 protocol is not being used or your relay’s FW version matches any of the listed below no
action is required.
GE tracking number: 572-7
E
UR IEC6870-5-104 implementation has been enhanced to support “Test command with Date/Time”
Products: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 5.72
Workaround: None
Description: IEC60870-5-104 determines that slave devices are to respond with a 16-bit value (test
sequence counter) and its corresponding timestamp when a test command is received. This firmware
version enhances the UR IEC60870-5-104 protocol implementation to the described test command.
GE tracking number: 572-3
C
The “IEC104 Point Lists” element has been changed to properly display analog values when only one
analog point is programmed
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.72, 5.83
