ABB Condition MonitoringMService
1.1. Target Group
MService is the embedded Condition Monitoring device for ABB Low Voltage Switchgears. Audiences
of this manual are service technicians and switchgear operators on site.
The document describes how to get the device installed in a switchgear network, and how to operate
it using the web-based user interface.
The reader shall be familiar with the terms and concept of ABB MNS Low Voltage Switchgear.
1.1 Use of Warning, Caution, Information and Tip icon
This publication includes Warning, Caution, and Information icons where appropriate to point out
safety related or other important information. It also includes Tip icons to point out useful hints to the
reader. The corresponding symbols should be interpreted as follows:
The electrical warning icon indicates the presence of a hazard that
could result in electrical shock.
The warning icon indicates the presence of a hazard that could result in
personal injury.
The information icon alerts the reader to pertinent facts and conditions.
Although Warning notices are related to personal injury, and Caution notices are associated with
equipment or property damage, the operation of damaged equipment could, under certain opera tional conditions,
result in impaired process performance leading to personal injury or death. It is,
therefore, imperative that you comply fully sigh all Warning and Caution notices.

OPC Open Platform Communications
The industrial de-facto standard for exchange of
information between components and process
supervision and monitoring applications using
TCP/IP based networks.

Following cyber security-based recommendations must be considered using MService device in an in dustrial Ethernet network environment:
• MService shall be connected to an isolated network in general. If MService is connected to a
plant network a firewall shall be considered to control access to MService web-based user inter face.
• Insertion of a USB drive / pen-drive / stick into a USB port of MService shall be prevented at any
time except connecting an external hard-disk for data backup purpose. Inserting a faulty USB
drive (e.g. with faulty USB-HID(*) descriptor) can lead to a stop of MService functionality. In such
a case MService will not record any data from connected field devices any longer and a device
reboot is required.
To prevent an unrestricted access to the USB ports of MService USB Port Locks shall be used.
These port locks reduce the risk of data leakage, data theft and unauthorized uploads with a
software-free solution that physically blocks USB ports from unauthorized access. There’s even
an option to block multiple adjacent ports with one lock and allow continued secure use of au thorized USB devices.
• User must log-off from MService when leaving the workplace to prevent another person using
the active login account. The log-off button must be used in this case as closing the Web
browser will not terminate the active web-session.
2.1 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 use the device to place it in a customer’s switchgear to support cus tomer 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 com missioning and ease of use.

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 su pervised 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 communi cation 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 com munication such as MSpeed (Variable Speed drives in MNS iS) and conventional modules.
In general, MService supports all types of modules which are also accessible in MView.
MService firmware version 7.7 is extended to MNS - Intelligent Switchgear,
UMC100/UMC100.3/M10x-M/Emax/Emax2 connects to MLink. In order to config ure MService to MNS – Intelligent Switchgear, MNS Engineer, MNavigate and
MNavigate Plus version release 7.7 onwards shall be used. See more details in
