1. General
1.1. Target Group
This document describes communication and control interfaces used in LVS Digital (includes
MNS Digital and NeoGear Digital switchgear) and LVS Digital Upgrade (upgrade from INSUM1
/ 2) projects utilizing ABB motor controller M10x [M101 / M102].
The manual is primarily intended for those requiring information on how to access infor-
mation and data provided from Digital Gateway.
Furthermore, the document provides information for control system and application engi-
neers how to integrate MNS Digital [Upgrade] as Fieldbus component into PLC or higher-level
Process Control Systems.
It is assumed that the reader of this manual is familiar with basic terms of Fieldbus and con-
trol communication (e.g. basic knowledge about Modbus etc.).
1.2. 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 caution icon indicates important information or warnings related to the con-
cept discussed in the text. It might indicate the presence of a hazard that could re-
sult in corruption of software or damage to equipment/property
The information icon alerts the reader to pertinent facts and conditions
The tip icon indicates advice on, for example, how to design your project or how to
use a certain function
Although Warning notices are related to personal injury, and Caution notices are associated
with equipment or property damage, it should be understood that the operation of damaged
equipment could, under certain operational conditions, result in impaired process
performance leading to personal injury or death. It is therefore, imperative that you comply
fully with all Warning and Caution notices.

1.3. Terminology
List of the terms, acronyms, abbreviations and definitions that the document uses.
Abbreviation
Term
Description
Alarm
Alarm is defined as status transition from any
state to abnormal state. Status transition to ab-
normal state can be data crossing over the pre-
defined alarm limit.
Bus Local
A Control Access term describing that the M10x
accepts its commands from a device on the
switchgear control network, e.g. the Web Inter-
face, MView.
COTS
Commercial off the
shelf
Commercial off the shelf product, term to de-
scribe products available on the market, ready to
use
DCS
Distributed Control
System
See also PCS
Eth.
Ethernet
Ethernet is a local area network (LAN) technology.
The Ethernet standard specifies the physical me-
dium, access control rules and the message frames.
Event
An event is a status transition from one state to
another. It can be defined as alarm, if the state is
defined as abnormal or as warning as a pre-alarm
state.
FD
Field Device
Term for devices connected to the Fieldbus (e.g.
motor control units or circuit breaker protection)
GPS
Global Positioning
System
System to detect local position, universal time
and time zone, GPS technology provides accurate
time to a system
Hardware Local
A Control Access term describing that the M10x
accepts its commands from the Hardwired inputs,
when the respective Local control input is set to
true.
HMI
Human Machine In-
terface
Generic expression
LVS
Low voltage switch-
gear
A factory-built assembly built to conform with IEC
61439-1
