das Managementsystem
ControlMaestro 2008 übergeben“,
lautet das überzeugende
Fazit des erfahrenen
A u t o m a t i o n s p r a k t i k e r s
Alexandre Mottas von PDC
SA. Auch komplexe Kommunikationsaufgabenlassen
sich schnell und fehlerfrei
bewältigen. Ein BACnet
Building Controller verarbeitet
bis zu 1.200 BACnet-Objekte.
Neben den üblichen
Objekten wie Analog, Digital,
Mittelwert, Zähler und
Pulskonverter stehen auch
komplexe Objekte wie Scheduler
und Kalender, Alarm,
Event und Trendlog zur Verfügung.
Somit verfügt das
Krankenhaus von La Chauxde-Fonds
über ein leistungsfähiges
und offenes Gebäudemanagement.
La Chaux-de-Fonds is situated
around 1,000 metres
above sea level, placing it
among Europe’s highest cities.
It is one of Switzerland’s
best known centres for the
clock and watch-making industry.
The town has a 150
bed hospital which, since
2006, has belonged to the
Neuchâtel Hospital Group.
The existing main building
was constructed in 1966.
Ever greater demands are
placed on hospital buildings
with regard to their technical
facilities. Integral building
and room automation allows
comprehensive control of
the considerable energy consumption
in a hospital, while
increasing comfort and improving
many processes. Luciano
Vermot, the Technical
Manager of Neuchâtel Hospital
Group, had a clear objective
for the complete renovation
of the building automation.
The new platform had
to be based on an open standard.
In 2008 when he attended
the Hilsa Exhibition and
learned about the new BACnet
solution, SCADA, from
Saia Burgess in conjunction
with ControlMaestro 2008,
he was ready to place a corresponding
contract with the
co-exhibitor DPC SA as the
system integration company.
Renovation while hospital
business proceeds
The challenge included,
among other things, carrying
out the entire renovation in
stages while business proceeded
as usual, with exactly two
days changeover time available
per switchgear combination.
All function descriptions
and diagrams had to be reedited.
For each stage, DPC
creates the entire switchgear
combination in its own workshop.
The installations are
fully programmed and tested
before they are assembled on
site. By the end of 2009, renovation
should be complete,
comprising arround 3000 data
points and 1500 messages
and alarms.
Anwendungen Solutions
Prinzipschema der neuen Gebäudeautomationsanlage
mit BACnet im Krankenhaus La Chaux-de-Fonds samt
Integration aller Energiemessungen.
Pictorial schematic of the new building automation
system with BACnet in La Chaux-de-Fonds Hospital,
including the integration of all energy measurement.
PCD3 type PLCs from Saia-
Burgess are used, together
with 5.7-inch web panels
as local control elements.
Saia BACnet Building Controllers
are general purpose,
open automation stations
and can be seamlessly integrated
into a BACnet network.
The application is
produced as usual with the
PG5 Controls-Suite programming
tool. It includes
a BACnet configurator that
allows complete freedom
to set the parameters of all
BACnet objects. As a result,
a smart solution can be
found for any conceivable
task.

Simple BACnet
engineering
Alexandre Mottas of DPC
SA, an experienced automation
practitioner, convincingly
sums it up this way:
“With the BACnet configurator
in the PG5, EDE files
are very easy to edit and
import. We can therefore
transfer all BACnet objects
from substations electronically
to the ControlMaestro
2008 management system.”
Even complex communications
tasks can be handled
speedily and without errors.
A BACnet Building Controller
processes up to 1200
BACnet objects. Alongside
the usual ones (such as
analogue, digital, average,
counter and pulse converter),
complex objects are also
available, e.g. scheduler
and calendar, alarm, event
and trendlog. As a result,
La Chaux-de-Fonds Hospital
has powerful, open
building management at its
disposal.
