Direct I/O Messaging

Direct I/O allows for the sharing of

high-speed digital information between

multiple UR relays via direct back-to-back

connections or multiplexed through a

standard DS0 multiplexer channel bank.

Regardless of the connection method,

direct I/O provides continuous real

time channel monitoring that supplies

diagnostics information on channel health.

Direct I/O provides superior relay-to-relay

communications that can be used in

advanced interlocking and blockingschemes.

• Communication with up to 16 UR relays

in single or redundant rings rather than

simplistic point-to-point configurations

• Connect to standard DS0 channel

banks through standard RS422. G.703

or IEEE C37.94 interfaces or via direct

fiber optic connections

• Built-in continuous loop and channel

monitoring provides real-time

diagnostics of your communication

channels with no external or handheld

tester required

Communications

The M60 provides advanced commun

ications technologies for remote data and

engineering access, making it the easiest

and most flexible motor protection relay

to use and integrate into new and existing

infrastructures. Direct support for fiber

optic Ethernet provides high-bandwidth

communications allowing for low-latency

controls and high-speed file transfers of

relay fault and event record information.

The available three independent Ethernet

ports, redundant Ethernet option and the

embedded managed Ethernet switch

provide the means of creating fault tolerant

communication architectures in an easy,

cost-effective manner without the need for

intermediary communication hardware.

The M60 supports the most popular industry

standard protocols enabling easy, direct

integration into DCS and SCADA systems.

• DNP 3.0

• Ethernet Global Data (EGD)

• IEC 60870-5-103 and IEC 60870-5-104

• IEEE 1588 for time synchronization

• Modbus RTU, Modbus TCP/IP

• PRP as per IEC 62439-3

Interoperability with Embedded

IEC 61850

Use the M60 with integrated IEC 61850

to lower costs associated with substation

protection, control and automation.  GE

Digital Energy’s leadership in IEC 61850

comes from thousands of installed devices

and follows on extensive development

experience with UCA 2.0.

• Replace expensive copper wiring

between devices with direct transfer of

data using GOOSE messaging

Role Based Access Control (RBAC)

Efficiently administrate users and roles

within UR devices. The new and advanced

access functions allow users to configure

up to five roles for up to eight configurable

users with independent passwords.

The standard “Remote Authentication

Dial In User Service” (Radius) is used for

authentication.

Event Recorder (Syslog for SEM)

Capture all cyber security related events

within a SOE element (login, logout, invalid

password attempts, remote/local access,

user in session, settings change, FW

update, etc), and then serve and classify

data by security level using standard

Syslog data format. This will enable

integration with established SEM (Security

Event Management) systems.

Fault and Disturbance Recording

The advanced disturbance and event

recording features within the M60 can

significantly reduce the time needed for

postmortem analysis of power system

events and the creation of regulatory

reports. Recording functions include:

• Sequence of Event (SOE)  – 1024 time stamped events

• Oscillography – 64 digital & up to 40 analog channels – Events up to 45s in length

• Data Logger and Disturbance Recording –  16 channels up to 1 sample/cycle/channel

The very high sampling rates and the large

amount of storage space available for

data recording in the M60 can eliminate

the need for installing costly stand-alone

recording equipment.

Cyber Security –

CyberSentry UR

CyberSentry UR enabled UR devices deliver

full cyber security features that help

customers to comply with NERC CIP and

NIST® IR 7628 cyber security requirements.

This software option delivers the following

core features:

AAA Server Support (Radius/LDAP)

Enables integration with centrally

managed authentication and accounting

of all user activities and uses modern

industry best practices and standards that

meet and exceed NERC CIP  requirements

for authentication and password management.

Advanced Motor Diagnostics

The Multilin M60 provides advanced motor

diagnostics including a broken rotor bar

detection function.  The broken rotor bar

detection is a condition maintenance

function that continuously monitors the

motor’s health while in operation.  The

advanced Motor Current Signature Analysis

(MCSA) continuously analyzes the motor

current signature and based on preset

algorithms, will determine when a broken

rotor bar is present in the motor. With fully

programmable alarms, the broken rotor bar

function will provide early detection of any

rotor problems and advise maintenance

personnel of the impending issue, allowing

for predictive maintenance of the motor and

prevention of catastrophic motor failures.

By providing early indication of potential

rotor problems, serious system issues,

such as reduced starting torque, overloads,

torque and speed oscillation and bearing

wear, can be avoided.  With the advanced

broken rotor bar detection system,

advanced warning of impending problems

reduces catastrophic failures, maximizing

motor life and system uptime.

Advanced Device Health

Diagnostics

The M60 performs advanced motor health

diagnostics and records this information

for each of the last 250 consecutive motor

starts.  Analyzing this diagnostic information

for operating parameters that have changed

over these successive starts can indicate

maintenance requirements before damage

occurs and costly repairs are required.

For each motor start, the M60 will provide

a record that contains the following information:

• Date of each motor start

• Motor acceleration time

• Motor starting current

• Motor thermal capacity used during starts

• Average motor load

• Running time after a start

Scalable Hardware

The M60 is available with a multitude

of I/O configurations to suit the most

demanding application needs. The

expandable modular design allows for

easy configuration and future upgrades.

• Multiple CT/VT configurations allow for

the implementation of many protection

schemes, including applications with

high-impedance machine grounding

• RTD inputs allow biasing of the

motor thermal model, as well as

overtemperature protection of the

stator, bearings, and other heat

sensitive components of the motor

• Types of digital outputs include trip

rated Form-A and Solid State Relay

(SSR) mechanically latching, and

Form-C outputs

• DCmA inputs are available to monitor

equipment and process parameters

Monitoring and Metering

The M60 includes high accuracy metering

and recording for all AC signals. Voltage,

current, and power metering are built into

the relay as a standard feature. Current and

voltage parameters are available as total

RMS magnitude, and as fundamental

frequency magnitude and angle.

FlexLogic

FlexLogic is the powerful UR-platform

programming logic engine that provides

the ability to create customized protection

and control schemes, minimizing the

need and associated costs of auxiliary

components and wiring. Using FlexLogic,

the M60 can be programmed to provide

the required tripping logic along with

custom scheme logic for motor breaker

control (including interlocking with internal

motor start supervision and synchrocheck),

interlocking schemes with adjacent

protections (for example, preventing

sympathetic tripping of healthy feeders),

and dynamic setting group changes.

IEC 61850 Process Bus

The IEC 61850 Process Bus module is

designed to interface with the Multilin

HardFiber System, allowing bi-directional

IEC 61850 fiber optic communications. The

HardFiber System is designed to integrate

seamlessly with existing UR applications,

including protection functions, FlexLogic™,

metering and communications. The Multilin

HardFiber System offers the following benefits:

• Communicates using open standard

IEC 61850 messaging

• Drastically reduces P&C design,

installation and testing labor by

eliminating individual copper terminations

• Integrates with existing M60’s by

replacing traditional CT/VT inputs with

the IEC 61850 Process Bus module

• Does not introduce new cyber security concerns

Advanced Automation

The M60 incorporates advanced automation

features including powerful FlexLogic

programmable logic, communication, and

SCADA capabilities that far surpass what is

found in the average motor protection relay.

The M60 integrates seamlessly with other

UR relays for complete system protection,

including the adjacent motors, feeders and

other balance of plant protection.
