ABB 1TGC910241M0201 MNS iS Interface Manual Profibus, Release 7.0

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.

The described functions are designed but may not be fully implemented in all details. 

Please refer to the current system guides and release notes regarding possible restrictions.

Web Server

A Web Server can be activated inside MLink. Through network connection web interface

information can be displayed on MView or a PC using web browser software. For details about

Web Interface see the document:

MNS iS Interface Manual Web Interface.

OPC Server

With MNS iS an OPC Server (DA & AE) is available. The software is typically installed on a

server as part of the automation control system. The software installation program is delivered

separately. If activated, the MLink functions as a data provider for the MNS iS OPC Server. For

details about OPC Server see the document:

MNS iS Interface Manual OPC Server.

Software Modules

MLink contains different software modules depending on its initial configuration. The software

modules are available on request.

Following software modules are available:

· Web Server

· OPC Server (DA & AE)

· Fieldbus

· Time Synchronization

· Redundant Operation

If a specific module is not available on the MLink, please contact your local ABB LVS Sales

organization should this be required.

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:

The EL operating mechanism of the Advac circuit breakers (in all versions) is fitted with a mechanical anti-pumping 

device which prevents re-closing due to either electrical or mechanical commands. 

Should both the closing command and any one of the opening commands (local or remote) be active at the same time, 

there would be a continuous succession of opening and closing operations.

The anti-pumping device avoids this situation, ensuring that each closing operation is only followed 

by a single opening operation and that there is no closing operation after this. 

To obtain a further closing operation, the closing command must be released and then re-launched.

Furthermore, the anti-pumping device only allows circuit-breaker closure if the following conditions 

are present at the same time:

 1. Closing spring fully charged

 2. Opening mechanical pushbutton and/or opening release coils (-MO1/-MO2) are not active.

 3. The circuit breaker is in the Open position.
