1. General
1.1. Target Group
Thisdocument describes communication and control interfacesusedinMNS Digital andMNS
DigitalUpgrade(upgradefrom INSUM 1 / 2) projects utilizing ABBmotorcontrollerM10x
[M101 / M102].
Themanual is primarily intendedfor thoserequiring informationon howto access infor-
mation and data provided from MNS Digital Gateway.
Furthermorethe document provides information for control system and application engi-
neers how to integrateMNS Digital [Upgrade] as Fieldbus component into PLC or higher level
Process Control Systems.
It isassumed thatthe reader of this manual is familiar with basictermsof Fieldbus andcon-
trol communication (e.g.basicknowledge about Modbus etc.).
1.2. Use of Warning, Caution, Information and Tip
icon
This publication includes Warning, Caution, and Information icons where appropriateto
point out safety relatedor 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 warningicon indicates thepresence of a hazard that couldresult in
electrical shock .
The warning icon indicates thepresence of ahazardthat could result in personal
injury
The caution icon indicates important information or warnings relatedto the con-
cept discussed in the text. It might indicate the presence of a hazard that could re-
sult in corruption of softwareor damageto equipment/property
The information icon alerts the reader to pertinent facts and conditions
Thetip icon indicates advice on, for example,howto design your project or howto
use a certain function
Although Warning notices are related to personal injury, andCaution notices are associated
with equipmentor property damage,it should beunderstoodthat theoperationof damaged
equipment could,under certainoperational conditions, result in impaired process
performance leadingtopersonalinjuryor death. It istherefore,imperative that you comply
fullywith all Warning and Caution notices.

Listof theterms, acronyms,abbreviations and definitions that thedocument uses.
Abbreviation
Term
Description
Alarm Alarm is definedas status transition from any
state to abnormal state. Status transition to
abnormalstate can be datacrossingover 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 onthemarket, ready
to use
DCS Distributed Control
System See also PCS
Eth. Ethernet Ethernet isa local area network (LAN)technol-
ogy. The Ethernet standard specifies the physical
medium, access control rules and the message
frames.
Event An event is a status transition from one state to
another. It can be definedas alarm, ifthestate
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 controlunits or circuit breaker pro-
tection)
GPS Global Positioning
System System to detect local position, universaltime and time zone, GPS technology providesaccu-
ratetimeto a system
Hardware Local A Control Access term describingthat the M10x
accepts its commands from the Hardwiredin-
puts, when the respective Local control input is
set to true.
