Refer to the Appendix at the end of this document for a description of the categories displayed.
Security Enhancements
N
Dual – Permission Access Control
Applicable: All URPlus products
The URPlus products have been enhanced with added security measures to ensure explicit permission
is granted from the controlling authority.
With the implementation of the Dual Permission Access Control in the URPlus, extra measures have
been taken to ensure incorrect changes are not made to the relays. With this enhancement, before
the user can make any changes to the relay settings, the system operator must first ‘surrender’ the
relay to grant the local operator the ability to make changes to the settings.
When the system operator ‘surrenders’ the relay, the local personnel may additionally be required to
enter a ‘Setting Level’ password before making any changes to the relay.
This enhancement to the Security features in the URPlus prevents legitimate users from making setting
changes on the incorrect relay. This also prevents unauthorized users from making any changes to
the relays settings even if the password is known.
E
Enhanced Security Audit Log
Applicable: All URPlus products
The security log in URPlus products has been enhanced to record the history of user commands
executed by the relay in the Security Audit Log. The Security Audit Log resides in a protected area of
memory that cannot be cleared by user action (either intentional or accidental) and provides a
powerful tool for cybersecurity policy auditing and analysis requirements.
Communication Enhancements

IEC 61850 Enhancements
Applicable: All URPlus products
IEC 61850 Enhancements have been made to the URPlus line, providing additional functionality to the
URPlus:
o

o
o
Performance of GOOSE messaging has been enhanced with a fixed scanning rate for
transmitted datasets regardless of the number of data items. The transmit latency for GOOSE
messages has been improved to be consistently 2 ms or less.
Logical nodes for XSWI (disconnect switch) and CSWI (control of switching elements) have been
implemented. The D90Plus now supports two (2) XCBR and six (6) XSWI and the C90Plus supports
six (6) XCBR and thirty (3) XSWI logical nodes, respectively. Individual CSWI logical nodes are
provided for each XCBR and XSWI logical node.
The control of circuit breakers and disconnect switches can now use Select-Before-Operate with
enhanced security.
The capability to map DPS (double-point-status) information in the URPlus has been implemented.
C90Plus Controller
E
Increased Number of control objects
Applicable: C90Plus
The C90Plus is now capable of providing individual control and monitoring of up to six (6) individual circuit
breakers and up to thirty (30) individual disconnect switches. These control elements have been mapped
to XCBR and XSWI
E
User-configurable Single Line Diagrams
Applicable: C90Plus
The C90Plus now features six (6) fully user configurable single line diagram display for the Graphical HMI
front panel option. This allows for the C90Plus to be used as a centralized bay controller for buses with up
to six individual bays.
D90Plus Line Distance Protection
E
Enhanced Subcycle Quadrilateral Distance Elements
Applicable: D90Plus
The D90Plus Quadrilateral (reactance) distance element comparators have been enhanced to provide
subcycle distance element operation for phase and ground faults for a wide variety of fault cases and
system conditions. The quad distance elements now use both the traditional phasor-based distance
algorithm in parallel with the new sample-based subcycle distance algorithm.
E
Tuned Digital CCVT Filter
Applicable: D90Plus
In release 1.60, a novel digital filter has been added to the input processing of voltage signals provided to
the D90Plus subcycle distance elements. This filter models the transient behavior of the connected CCVT
and applies a correction to each sample that numerically erases the error introduced by CCVT transients.

UR revision 5.60 release notes
This allows for fast distance element operating times over the zone of protection in the presence of CCVT
transients without intentional delays or reduced fault coverage, allowing operating time approaching
applications using magnetic VTs.
E
User-configurable Single Line Diagrams
Applicable: D90Plus
The D90Plus now features a fully user configurable single line diagram display for the Graphical HMI front
panel option.
URPlus Platform Enhancements
E
New High Density Digital I/O Module Options
Applicable: All URPlus products
Two new Digital I/O modules have been developed to provide the required I/O for many large-scale bay
control applications. This enhancement provides users with additional flexibility with digital I/O.
The new digital I/O modules available are:
o Type ‘E’ – 23 individual externally-wetted contact inputs
o Type ‘F’ – 12 Individual Form-A contact outputs
N
Ambient Temperature Monitoring
Applicable: All URPlus products
The URPlus products have been enhanced to include ambient temperature monitoring and alarming. With
the implementation of ambient temperature monitoring and alarming, the URPlus product family provides
the ability to alarm the user in conditions where the ambient temperature exceeds predetermined hot
extremes. With this enhancement, indication of air conditioning failure or improper ventilation can be
communicated by URPlus relays to the control room.

EnerVista Setup Software Enhancements
E
Support for URPlus release 1.60
Applicable: All URPlus products
The EnerVista URPlus Setup Program version 1.60 has been enhanced to support the additional features
and functions that are now implemented in the URPlus Release version 1.60.
N
Dual – Permission Access Control
Applicable: All URPlus products
The EnerVista URPlus Setup program has been enhanced to support added the security measures
implemented in the URPlus Release 1.60.
With the implementation of the Dual Permission Access Control in URPlus products, extra measures have
been taken to ensure incorrect changes are not made to the relays. With this enhancement, before the
user can make any changes to the relay settings, the operator must first ‘surrender’ the relay to grant the
user the ability to make changes to the settings.
N
Windows Vista Operating Environment
EnerVista URPlus Setup version 1.60 Setup software is compatible to operate in the Windows Vista
operating environment. In addition to supporting Windows Vista, version 1.60 set-up software also
supports Windows XP and Windows 2000.
EnerVista Viewpoint URPlus Engineer
N
EnerVista Viewpoint URPlus Engineer
EnerVista Viewpoint URPlus Engineer version 1.60 has been introduced to support all functionality of the
URPlus release 1.60. URPlus Engineer is a software package to allow graphical editing and real-time
monitoring of both Protection FlexLogic and Automation FlexLogic in URPlus products.
Upgrade paths
It is our recommendation that all customers upgrade to the latest version of URPlus firmware to take advantage
of the latest developments and feature enhancements. Firmware upgrades can be easily preformed using the
EnerVista URPlus Setup software. This software can also convert settings files from an older version to the latest
version and provides a Difference Report once the conversion has been completed. This Difference Report
identifies new settings and additional information to assist the user during the upgrade.
