1. GB - Product information
General All VEX units with EXact2 control have an integrated Modbus RTU interface, so they can
communicate with other modbus-enabled devices in the building.
Modbus communication that must operate via TCP/IP, must use a MTCP module or a
third party module. MTCP is a gateway that coverts data between the Modbus RTU and
the Modbus TCP protocol. MTCP acts as a Modbus/TCP slave on an Ethernet network.
Start-up and
commissioning
If communication is implemented via a Modbus network, it works in parallel with the
unit's HMI panel. That is, settings made via the HMI panel can be changed via the mod-
bus network and vice versa. The latest change made will be the valid change.
Warning! Switch off power to the unit before opening the doors. If the unit has
been stopped via the HMI panel, it can be started later via the modbus
network.
Specialist
knowledge
Certain settings require specialist knowledge and therefore cannot be set directly via the
Modbus network. EXHAUSTO recommends commissioning is carried out by qualified
professionals, directly via the HMI panel.
Monitoring The most important parameters for monitoring daily operations can be set.
If the unit is monitored from a main workstation, the screen display used for monitoring
should be kept as simple as possible, so that it is manageable for the user.
Alarms All alarms can be monitored and accessed via modbus. All alarms can be saved on the
main workstation (PC) to give an overall view of the installation. There may be up to 16
current alarms listed on the "Current list" in the EXact2 control Menu 4.5. All 16 alarm
register addresses are listed at the back of this instruction.
See "EXact2 Control System Basic Instructions" for a description of the alarms.
Data collection Post-commissioning, the set points on the ventilation system must to be optimised. It is
advisable to have the temperature and airflow curves and other operating values avai-
lable. These values can be read from the unit via the modbus network and must be log-
ged and saved on the main workstation (PC).

1.1.1 Interaction with other technical installations
Interaction with
other technical
installations
To achieve comfort and the most energy-efficient operation, the VEX unit is designed to
interact with other technical installations, e.g. heating installations, motion sensors and
window switches.
There are a wide range of components available on the market for this purpose, also for
altering or expanding the installation at a later date.
2. Assembly
2.1.1 Factory fitted
If MTCP is ordered as factory fitted, no mechanical assembly is necessary. MTCP is
located in the control system box on the unit. (Photo: example VEX240).

2.1.2 Retrofitting of MTCP - general
When MTCP-AS is ordered for retrofitting, the module must be mounted on a DIN rail in
the control system box. See the following sections for locations on the various VEX mo-
dels. The accompanying shield terminal block must always be fitted to shield the cables
on the MTCP module cable.
The MTCP module is mounted on the DIN rail as shown on the illustration:

2.2.3 Description of network type, speed, topology, etc.
• EXact2 Modbus uses the Modbus RTU protocol over the RS-485 bus topology
with 120 ohms termination resistors in every termination point. The modules
have built-in termination resistors.
• MTCP uses Modbus over the TCP protocol over the Ethernet network.
Termination Check that the termination resistor is connected via jumper JP2 on the webserver.
2.2.4 Connection to Ethernet network
The Ethernet is con-
nected to the front of
the MTCP module. It

1. DK - Produktinformation
Generelt Alle VEX-aggregater med EXact2-styring kan leveres med Modbus RTU interface for
kommunikation med andre Modbus enheder i bygningen, såfremt aggregatet er forsynet
med en webserver.
Skal Modbus kommunikationen køre via TCP/IP, kan/skal der anvendes et MTCP mo-
dul.
MTCP er en gateway, som konverterer data mellem Modbus RTU og Modbus TCP pro-
tokollen. MTCP optræder på Ethernet netværket som en Modbus/TCP slave.
Opstart og
indregulering
Hvis der er kommunikation via et modbus-net, virker dette parallelt med aggregatets
HMI-panel. Det vil sige, at indstillinger foretaget på HMI-panelet kan ændres via mod-
bus-nettet og omvendt. Den sidst foretagede ændring vil være gældende.
Advarsel! Afbryd spændingsforsyningen til aggregatet, inden lågerne åbnes.
Hvis aggregatet er stoppet på HMI-panelet kan det senere blive startet
via modbus-netværket.
Specialist-
kendskab
Visse indstillinger, som kræver specialistkendskab, kan ikke indstilles direkte via mod-
bus-netværket. EXHAUSTO anbefaler, at idriftsættelse foretages af faguddannede folk,
direkte på aggregatets HMI-panel.
Overvågning Til overvågning af daglig drift stilles de vigtigste driftsparametre til rådighed.
Hvis anlægget overvåges fra en hovedstation, anbefales det, at skærmbilleder,
der anvendes til overvågning, holdes så simple som muligt for at bevare overblikket.
Alarm Til overvågning af alarmer stilles alle alarmpunkter til rådighed via modbus.
Alle alarmer kan gemmes på en hovedstation (PC), og giver et fælles overblik over
installationen. Der kan være op til 16 aktuelle alarmer på listen i EXact2-styringen menu
4.5 “Aktuel liste”. Se registeradresselisten bagerst i denne vejledning for at se de tilsva-
rende 16 registrenumre for alarmerne.
For beskrivelse af alarmer se “EXact2 Automatik Basisvejledning”.
Dataopsamling Når et ventilationssystem efter idriftsættelsen skal optimeres med hensyn til setpunkter,
er det til stor gavn at have trendkurver for temperaturer, luftmængder og andre driftsvær-
dier. Disse værdier kan hentes fra aggregatet via modbus-nettet, og skal logges og gem-
mes på en hovedstation (PC).

1.1.1 Samspil med andre tekniske installationer
Samspil med
andre tekniske
installationer
For at opnå komfort og energimæssig optimal drift, er det en fordel at VEX-aggregatet
har et samspil med andre tekniske bygningsinstallationer - f.eks. varmeinstallationer,
bevægelsesmeldere eller vindueskontakter.
På markedet findes der et stort antal komponenter, som kan sikre dette samspil, også
hvis installationen senere skal ændres eller udbygges.

2.1.1 Fabriksmontage
Hvis MTCP er bestilt som fabriksmonteret, skal der ikke laves nogen montage.
MTCP er placeret i automatikboksen på aggregatet. (Foto: eksempel VEX240)

2.1.2 Eftermontage af MTCP - generelt
Når MTCP-AS er bestilt for eftermontage, skal MTCP modulet monteres på DIN skinnen
i automatikboksen, se de følgende afsnit for placering i de forskellige VEX-modeller.
Den medleverede skærmbøjle skal altid monteres for at skærme MTCP-modulets kabel.
MTCP modulet monteres på DIN-skinnen som vist på illustrationen:
