GE Multilin™ M60 Motor protection system ​IEC 61850 Process Bus

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.

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.
