UR Family Firmware 5.83 - Release Notes
17
C
The UR real time clock element has been changed to correctly calculate UTC when receiving IRIG-B
time code signal with IEEE1344 extension
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83
Workaround: None
Description: UR devices do support receiving IRIG-B signals with or without IEEE1344 extension. The
IEEE1344 extension adds additional information (such as year, DST, and time zone) to the IRIG-B signal.
Prior firmware versions have evidenced that UR devices receiving IRIG-B signals with IEEE1344 extension
may not accurately calculate UTC, which directly affects GOOSE messages time stamp (must use UTC
reference). This FW version ensures UTC is correctly calculated under the described conditions. For more
details on the UR real time clock functionality, see the UR instruction manual of any applicable device.

Cyber security – CyberSentry
TM
C
The UR operating system debug port has been changed to reject Ethernet traffic
Products: B30, B90, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Corrected firmware: 5.83, 5.92
Workaround: None
Description: All UR devices equipped with an Ethernet port support the logical port #17185. This logical
port is a debug port dedicated to the device operating system. This port is used for factory service only.
Any port scanner connected to a UR Ethernet port detects that port as “open,” however UR devices with
this firmware version do support a data filter that discards any data for the debug port. The debug port
traffic is only allowed when a factory service password requirement is met. End users having UR devices
with an Ethernet port and concerned about cyber security in their substation LAN can upgrade their
devices with this UR firmware version. UR devices with no Ethernet port are not affected.
GE tracking number: 592-1
N New keyboard command for password reset and default settings aligned to NERC-CIP requirements
Products: B30, B90, C30, C60, C70, D30, D60, F35, F60, G30, G60, L30, L60, L90, M60, N60, T35, T60
Impacted firmware: 5.82
Corrected firmware: 5.83, 5.92
Workaround: None
Description: UR devices have an encrypted version of the “Setting” and “Command” passwords that can
be used to retrieve the actual password when users forget any of the passwords. To use the previous
encrypted passwords, users have to contact GE Multilin’s technical support team and provide their
encrypted passwords (one or more per relay), then technical support provides a decrypted version for
each submitted password. This firmware version introduces a new mechanism for password reset (not
password retrieval) that gives users independence and complete ownership of the password reset
procedure. One key code can be used on all UR devices. To reset the password, users must now submit a
key via the front panel (users can obtain their key by contacting GE technical support). This “password
reset command” also clears all settings and event records, which is actually aligned to the NERC-CIP R7.1
and R7.2 requirement. Users are advised backup the relay data previous to submitting the password reset
command. For details, see any UR instruction manual.
