UR Family Firmware 5.83 - Release Notes
Events and records
R
The “Real Time Clock” element has been modified to ensure that the events-timestamp is correct
when the DST function is active and power is cycled
Products: B30, B90, 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: The Real Time Clock element has Daylight Saving Time (DST) functionality that allows the
device to follow the DST local rules. Previous FW versions show that if the DST function is active and the
device auxiliary power is cycled, the events timestamp can shift one hour from the actual time. This FW
version ensures the DST time is preserved when the auxiliary power is removed from the relay.
Furthermore, the DST function setting is correctly applied to the timestamp that is shown on the fault
report summary page when accessed through UR Setup Software or web browser.
GE tracking number: 590-14
P
The timestamp routine has been changed to prevent timestamp discrepancies and a longer
protection pass period when daylight savings time (DST) is enabled
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 5.91
Workaround: None
Description: When the DST function is enabled, the timestamp routine checks whether the timestamp
needs to be updated according to DST for every UR event record. On a relay generating dozens of events
within one protection pass period; this routine can make the protection pass longer than the relay
specification. Therefore, the communication elements running at the end of the protection pass use the
latest protection pass time, which forces a discrepancy between the internal event recorder and
communication protocol time stamp. A UR relay generating dozens of events within one protection pass
period can also lead protection and control elements to operate out of specification. This firmware version
prevents timestamp discrepancies and allows a longer pass period when DST is enabled.
GE tracking number: 591-1
R
UR Event recorder to avoid events flooding when there is an Ethernet port failure
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: The UR Event Recorder registers all UR self-test events that include Ethernet Port Failures “Pri
Ethernet Fail/Sec Ethernet Fail”. Relays with previous firmware versions show the event recorder properly
registers Ethernet Failure events when they appear. However, as long as the Ethernet failure condition
remains, this event is generated every two seconds, which floods the event recorder. This firmware
version fixes the event recorder to prevent event flooding by registering only one event per Ethernet port
failure. UR devices with no Ethernet ports are not affected by this issue.
GE tracking number: 601-6
E
Event description added to distinguish event types in an Event Report
Products: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 7.20
Workaround: None
Description: Event descriptions of contact inputs and outputs, virtual inputs and outputs, direct inputs and
outputs, remote inputs, double point inputs, field contact inputs and outputs, field latching outputs, shared
inputs and outputs, FlexElements, and digital elements now include added abbreviated text to distinguish
among various event types with the same name. For example, Contact Input 1 ON with default settings is
presented as Cont Ip 1 ON(CI1)
