ABB 1TGC910261M0201 MNS iS Interface Manual Redundancy, Release 7.0

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. 

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.

System Overview

Product Concept

The MService device implements an innovative approach to condition monitoring: 

The supervision of the performance and health status of a MNS and MNS iS switchgear are made

possible with a small-scale and easy-to-use embedded industrial PC.

The MService implements the whole condition monitoring concept from collecting field level

real-time data to performing assessment algorithms. 

Based on that, it is possible to work out a prognosis of developing situations and prompting the operator for action. 

However, if the situation continues and results in a tripping or failure, the MService offers clear diagnosis for fast problem resolution.

MService targets two main application scenarios:

 Customer’s staff can use the device for performance analysis and continuous support of

maintenance planning for MNS and MNS iS system, with MService installed as permanent part of the switchgear.

 ABB’s service personnel uses the device to place it in a customer’s switchgear to

support customer decisions in keeping the switchgear in good condition by collecting

data for a certain time and derive an assessment on the switchgear performance and operational status.

To fit to these scenarios, the MService employs a small-scale, compact approach to enable fast

commissioning and ease of use.

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.)
