ABB Modbus Communication Protocol Manual 1MAC057386-MB

REF611 is a dedicated feeder protection relay designed for the protection, control, 

measurement and supervision of utility substations and industrial power systems.

The feeder protection relay REF611 can be supplied either with directional or non-directional overcurrent and earth-fault protection. 

Directional earth-fault protection is mainly used in isolated neutral or compensated networks, 

whereas the non-directional earth fault protection is intended for directly or low-impedance earthed neutral networks.

REF611 is a member of ABB’s Relion® product family and part of its 611 protection and control series of relays.

Product Description

REM615 HCMJAEADNEC2BNN11E is a motor protection measurement and control device in the ABB Relion 615 series. 

This device is designed to protect, control, measure and monitor asynchronous motors in the manufacturing and processing industries.

Main features:

Integrated protection, control, measurement and monitoring.

Provides motor start, load loss monitoring, thermal overload, motor reversal protection with sensors or traditional CT/PT.

With pre-configured standard configurations, you can also quickly and easily meet different application requirements through functional configuration.

Pluggable design for quick installation and testing.

Large LCD display with editable single line charts, accessible locally or via an easy-to-use HMI based Web browser.

Provide thoughtful product life cycle service.

Product parameter

In addition, the REF543KM127AAAA feeder terminal unit has a fault location function to locate short circuit faults in various networks. 

It also offers a large number of PLC functions, allowing multiple automation and sequential logic control functions to be integrated in one unit,

thereby reducing the need for hard wiring between feeder terminals.

Specific product information, such as product ID, type naming, product description, weight, dimensions, etc., can be found in ABB’s official data sheets. 

The REF543KM127AAAA feeder terminal unit has a net weight of 7.7 kg and is sold as spare parts

This includes:

 Motor starter and feeder modules (all sizes), which are equipped with measuring and

communication electronic device MControl

 Motor starter and feeder modules (all sizes), which are equipped with intelligent device,

UMC and M10x, communicates to MLink.

 Circuit breakers connected to the switchgear communication with the interface MConnect

 Circuit breakers connected to the switchgear communication with the interface MLink

Excluded from supervision in MService are all modules not connected to the internal switchgear

communication such as MSpeed (Variable Speed drives in MNS iS) and conventional modules.

Fieldbus

MLink can include Fieldbus communication to DCS. The type of Fieldbus must be selected

before ordering the MLink type. The Fieldbus specific information (PROFIBUS, MODBUS etc.)

can be found in the following documents:

MNS iS Interface Manual Profibus

MNS iS Interface Manual Modbus

MNS iS Interface Manual Profinet IO

Supported Functions

MService Condition Monitoring covers the following main functions:

 Collection of operational data of the supervised modules

 Collection of all alarms and trips generated in the supervised modules

 Collection of maintenance warnings derived from additional assessment logic related to the supervised modules.

 Display of the MNS or MNS iS system structure highlighting modules signaling problems

 Display of historical data in trend displays

 Detailed information on the identification, location, and type of supervised modules

 Online supervision of temperature or power loss related problems within individual cubicles.

MService can supervise all modules in MNS and MNS iS, which are connected to the internal

switchgear communication bus.
