Dear Reader,
This second edition of BACnet Middle East Journal comes to
you at a time when the construction industry is shifting gears
across the region. As we all know not all countries were
equally affected by the recent recession. Nations fortunate
enough to come through unscathed are witnessing strong
new construction activity, whereas those that were impacted
are having to come up with new strategies to stay in the race
for economic superiority.
Whether new construction or retro fit, one cannot get away
from the reality of multi-vendor environments as building
owners and contractors continuously strive for economical
and best-of-breed solutions in this era of austerity. This
approach is naturally resulting in a multitude of product
brands that are using a variety of communication protocols
within any given project.
BACnet as a systems integration technology is being
successfully deployed in both scenarios. In new construction,
BACnet products are being installed right at the field or
zone level on HVAC and Electrical equipment. In retrofit
buildings, a variety of BACnet gateways are allowing legacy
products to become part of a new overarching automation
system that uses BACnet at the building’s IP layer.
BACnet is also doing its part in the drive for sustainable
environments by nations across the region. By facilitating
the integration of various utilities into a larger energy
management system, BACnet is becoming a technology
of choice to deliver sustainable ideals across the buildings
industry.
To a large extent all this was possible due to product
manufacturers that want to offer a choice to their customers
by getting away from monopolistic or proprietary
technologies. This is no mean feat – it calls for immense
resolve to deliver ultimate customer satisfaction to be able
to adopt open standards such as BACnet. We salute these
valiant leaders of our industry.
Happy reading of the Second BACnet Middle East Journal!

Hanover Airport with BACnet-Certified
Automation System
Rising energy prices and a change in environmental awareness call for the
ecological, energy saving operation of buildings and property. For this, an
essential precondition is intelligent building management with fully integrated
building automation across all plant groups. In practice, however, the solutions
encountered are vendor-specific islands with different communications
protocols that can only be tied up to a central management system with great
difficulty. These «old woes» of the sector are increasingly unaffordable and
unmanageable. Today, the demand is for integrated concepts that, with one
click, can give operators an overview of all plant in a building or property.
An example is BACnet, the vendor-neutral protocol standard for unified
communication across different plant groups. There is a particular challenge if
BACnet-compatible devices only gradually come into use and if old, proprietary
systems have to be tied into a central BMS within a defined period. The
following article describes how such a challenge was successfully overcome in
building automation and management technology at Hanover Airport.
The company Flughafen
H a n nove r - L a n g e n h a g e n
GmbH took the decision
to install a BMS fit for
future needs to manage and
control all facilities like i.e.
HEVAC, cooling, sanitation,
electrical, combined heat
and power, boiler house,
aircraft deicing and ground
filter systems. At the same
time they started the
planning for the new Airport
Plaza shopping center. It was
the right moment to specify
the entire project around an
open BMS. Therefore, the
decision to go for an open and
recognized communication
standard like BACnet was
obvious.
In the new Airport Plaza shopping centre at Hannover-Langenhagen
Airport, all building management plant groups are controlled by
BACnet®-compatible automation stations of the Saia®PCD3 type.
In search of BACnet-­
compatible controllers
The aim was to build the
new Airport Plaza shopping
centre
with
BACnetcompatible
automation
stations and simultaneously
integrate pre-existing plant
groups within the new
BACnet. The first step was
to find a suitable controller.
This involved a tender call
and multi-stage qualification
process to determine the
adequate suppliers for the
management and process
levels.
To
check
that
the
BACnet-compatible
controllers actually delivered
in practice what they
promised in theory, four
suppliers were invited to
an on-site test set-up. All
stations were programmed
with a room-air system

The automation stations

all
specifications to customers’
entire
satisfaction
and
were selected for the
project. In addition, users
liked the system’s easy,
intuitive operability and
were won over by its very
comprehensive
BACnet
implementation, which far
exceeds the standard and is
unique in the market. The
entire Saia®PCD automation
system family is BTL
certified and compliant to
BACnet Building Controllers
(B-BC)
according
to

building automation, plus
23 data objects in line with
the ANSI / ASHRAE 1352004 standard for data
exchange, BACnet programs
and
BACnet
services.
Saia®PCDs include support
for numerous interfaces,
an integral web server and
the ability to add extra
IT memory modules. Last
but not least, the family’s
modular structure makes
for flexibility in adapting to
individual solutions. Thanks
to the automation library
DDC-Suite Version 2.0,
all the necessary BACnet
objects for an application are
generated automatically.
Finding a suitable
management system
Even with the use of BACnet
in the airport’s new building,
a central management system
is necessary to monitor
and control both new
and existing installations.
Implementation
of
the
management
level
was
awarded to INGA after it too
had proved itself against four
competitors. This involved
integrating the test set-ups
into the management system
and then demonstrating
numerous
compulsory
func­tions: e.g. device and
network management, data
sharing between substations,
event-oriented alarm for­
warding, scheduling, at
least six priority levels for
messages, trend plotting in
five-minute increments, plus
implementation of a defined,
30-character address key.
INGA won approval with
its economical proposal
both for integration and any
subsequent work arising.
Additional advantages were
the modern control concept
based on web technology,
the use of standard tools for
operation and maintenance,
and the excellently matched
INGA-IBS
management
soft­ware.
The present ­
meets the future
At the start of this upgrade
to the new communications
standard there were barely
70 automation stations from
a variety of manufacturers in
the entire premises. One way
of integrating these stations
into BACnet was to retrofit
appropriate
interfaces.
However, that would involve
much work and considerable
costs. A crucial advantage of
the vendor-neutral INGAIBS management software
and Saia®PCD automation
system used at Hanover
Airport is the capacity for
simultaneous
connection
of different automation
devices and bus systems
from various manufacturers
on a uniform user interface.
Thanks to an integral
interface, it is possible to
integrate BACnet objects,
new PCD3 controllers, and
conventional
automation
stations directly.
The management system
now connects 73 automation
stations and a total of 866
installations, 136 different
system images have been
implemented and seven
operator positions created.
The complete system now
manages over 17,000 data
points. This means that
the management software
also offers a good solution
for systems that are being
upgraded
to
BACnet
step by step.The example
described here shows that
this will also work in
practice. For some time now,
new
BACnet-compatible
Saia®PCD3 controllers to­
gether with pre-existing
automation sta­tions from
various manufacturers have
been reliably monitored by a
central process ma­nagement
system. At Hanover ­A irport,
a future-proof solution is
in use that can easily be
expanded and adapted to
every new requirement.

Achmea Centraal Beheer:
Revitalization and Redevelopment
with Future Oriented Technology
At the end of the Veluwe nature reserve in the middle of
the Netherlands lies the town of Apeldoorn. Famous for
Paleis Het Loo, one of the Dutch royal family’s residences,
but also known for accommodating one of the largest
branches of the Dutch insurance giant, Achmea.
The present office has 4
towers, each with 5 floors.
The towers are linked to
each other by a cross-shaped
atrium and offer enough
space for more than 2,500
employees. In the middle of
the 1990s the then called
Centraal Beheer moved
into the almost 27,000m²
building.
At that time the building
had constructional and
mechanical novelties in­
stalled in order to optimize
the use of energy needed
for heating and cooling.
In 2008 the need arose to
replace the old-fashioned
lighting control system. In
2009 after some research
and studies it was decided
to procure an integral
system
for
controlling
the lighting and the air
conditioning.
Important
issues were the need to
arrange spaces freely and
achieve effective flexibility
for internal movement, and

the building-related facilities
and links to other buildings.
Opportunities for linking
other buildings and the
integration of buildingrelated
provisions
were
important
issues
for
Achmea because of the
intended expansion of the
headquarters into a campuscomplex of 6 buildings.
After a selection procedure,
Achmea chose the openness
of BACnet for both the
revitalisation
of
the
present building and the
construction of the new
Campus. To achieve the
highest performance and to
realise the most forwardlooking
communications,
Ethernet (IP) was chosen as
the information carrier for
the building automation,
with
BACnet
Building
Controller (B-BC) as deviceprofile.
Present offices
The new BACnet / IP station
for local automation ‘ecos’
from the EY-modulo 5 family
from SAUTER has been
used for the post-regulation.
The freely programmable
functionality for linking up
the HF-lighting, controlling
the sun blinds and regulating
the climate is standardly
available on the station. The
combination, along with
the fact that the regulator is
BTL-certified in accordance
with the highest BACnet
device profile B-BC, make
the ecos the perfect solution
for giving form to Achmea’s
requirements.
The phased rebuilding of
the floors was a logistic
process planned in great
detail
beforehand.
The
local station regulates and
controls the electrical and
mechanical installations on
two constructional plans
at the same time. This
means that the number of
places where a secondary
automation station is fitted
is halved, but that each plan
can be regulated separately;

the technical automation for
these buildings.
Several data centres are
housed in the building.
Eventually the function of
the data centres will elapse
owing to the new building.
The decision to keep the data
centres in the building for
longer fell even before the
revitalisation of the postregulation was commenced.
The automation of the
primary installations must
also be replaced to comply
with the newest demands.
The choice of BACnet / IP,
which had already been made
for the local automation,
gave the data centres the
advantage of relatively easy
realisation of redundancy of
the primary automation and
communications. The data
centres and other primary
installations were rebuilt
within a few weekends via a
strict protocol, in which FAT
and SAT were part of the
automation.

BACnet Unlocks Full Interoperability, Total
Scalability and Real Vendor Independence
As a Facility Manager you run a continuous process of
service provision to every single worker in your building
and your performance will be measured by his satisfaction
at the lowest possible service cost. If you only could,
would you like to operate from the same enterprise
dashboard or would you prefer to spend your time
in learning and running many different systems with
different concepts and different languages?
It sounds like a defiant
question with an obvious
answer, but ironically this
is what is still happening in
many buildings around the
world. Thank goodness,
the world is changing and
facility managers are masters
of this evolution demanding
more and more integrated
systems.
BACnet can be considered
as an Integration platform
and Interoperability is its
main feature. Integrating a
proprietary sub-system, a
“gateway” device translates
the existing proprietary
protocol in BACnet. Pro­
prietary functionalities are
preserved taking advantage
of BACnet interoperability.

Focus on Building Applications –
An Introduction to BACnet-Routing
Frank Schubert1
The media in BACnet
BACnet supports a total of 7
different media. Routers are
devices to connect the media and
provide the transport from and to
the connected layers. This article
explains the BACnet routing and
the project requirements for a
correct setup.
BACnet in the ISO / OSI model
As shown in figure 1 BACnet
is
designed
according
to
the
ISO / OSI
model
for
communication.
Each
layer
provides a special functionality
and maintains interfaces to higher
and lower layers. This assures
independence from certain layer
requirements and allows interconnecting different media. Just
as information, BACnet does
not support the layers 4-6; those
are not required for BACnet
communication. In Addendum
135-2008q Zigbee is additionally
specified as a wireless medium to
be used with BACnet.
The advantage to use multiple
media in a project is to achieve
the best possible speed (e.g.
Ethernet connections, which are
limited to 100m between two
active components using CATcable but with a bandwidth up
to Gigabit / s) or cheapest possible
wiring (e.g. using LonTalk or
MS / TP on cheap wires and
high distances, but with a lower
bandwidth below 100 kbit / s), or
using public phone-lines to setupdial-up connections or using
Zigbee for wireless connections.
The network layer 3 is used to
connect the different media.
BACnet routers are devices
connecting the different media
and are intended to transport
the messages from and to the
connected layers. Router devices
1
may or may not have a BACnet
application associated but it is
a good recommendation to use
routers supporting an application.
This allows to determine BACnet
routers using BACnet application
services like “Who-Is” or to read
the routers’ device object.
BACnet network numbers
To distinguish the different
networks, each BACnet network
shall be assigned a unique
BACnet
network
number
within the entire BACnet internetwork. The network number
is known to the router devices
for each of the connected media.
The network number range is
specified in the range from 1 to
65534, while 65535 specifies a
broadcast destination. A value
of zero is sometimes used to
specify a connection to the local
network if a device doesn’t know

the Advisory Board and Working Group Technique of the BIG-EU
as well as training-leader of the BACnet Interest Group Europe,

the number of the network it is
connected to.
Note: BACnet allows only
one single route through the
entire network. If the same
network number is assigned to
different networks and is not
unique anymore, routers cannot
determine the correct route to the
devices which leads to erroneous
or missing communication.
Routers vs. Half-Routers
BACnet routers are devices that
interconnect two or more BACnet
networks to form a BACnet
internetwork. PTP (Point-toPoint using EIA-232) connections
are always established between
two half-routers that together
form a single router (temporary
connection). A network number
is not assigned to half-router
connections, the half-routers
always route to connected
physical or virtual networks.
The network layer messages
Router devices maintain their
routing tables by exchanging
messages on the network layer.
BACnet specifies a total of 10
different messages as explained
below:
X’00’: Who-Is-Router-To-Net­
work: This message requests the
router to a specific network or
may be sent as a general query to
request all routers in the net­
work.
X’01’ : I -A m- Router -To - N e t­
work: This message is sent at
start-up to introduce to the net­
work or as a response to a WhoIs-Router-To-Network message.
X’02’: I- Could-Be-Router-ToNetwork: This message is sent
by a half-router which knows the
requested network and is able to
establish a connection (e.g. dial
over a public phone line to an­
other half-router).
X’03’: Reject-Message-To-Net­
work: This response is sent by a
router in case the message can­

not be relayed to the destination
network.
Table 6-1. Maximum NPDU Lengths When Routing Through
Different BACnet Data Link Layers
Each network has a unique
network number assigned.
X ’ 0 4 ’ : Rout e r - B u s y-To - N e t­
work: This message is sent if the
router is temporarily unable to
process routing messages to the
specified network.

B-PAT
To provide a network overview
to facility managers or project
engineers the BACnet Interest
Group Europe developed an Excel
spreadsheet file format called
B-PAT (BACnet Project Address
Table). Using this file allows an
overview about all media and
devices installed within an entire
BACnet network. Additionally
some macro functions check for
duplicate addresses, instances
numbers, network numbers, etc.
The B-PAT file and description
can be downloaded from www.
big-eu.org without cost.
X’06’: Initialize-Routing-Table:
This message is used to send a
new routing table to a router or
to query the content of the rout­
ing table from a router.
X’07’: Initialize-Routing-TableAck: This message is used as a
response to an Initialize-Rout­
ing-Table message.
X’08’: Establish- ConnectionTo-Network: This message is
used to command a half-router to
establish a connection to the re­
quested network, e.g. over public
phone lines.
connection is involved the
maximum APDU size needs to
be restricted to 501 octets for all
BACnet devices.
MAC-Address sizes
While in ISO 8802-2 Type 1
and BACnet / IP 6 octets are
used, MS / TP uses 1 octet only,
LonTalk may use 2 octets or 7
octets depending on the mode.
For the future BACnet devices
shall be capable of supporting
up to 18 octets (for the next
generation of the Internet
X’09’: Disconnect-ConnectionTo-Network: This message is
used to command a half-router to
disconnect a connection to the
network, e.g. by hanging up the
modem-line.
Connecting different applications
When
connecting
BACnet
devices using different media
a few restrictions need to be
considered network-wide.
APDU length
The maximum length of APDUs
(Application Protocol Data Units
= application messages) of the
different media is specified in the
BACnet standard.
Router devices in BACnet are
not specified to segment and reassemble messages. This means
the maximum size needs to be
specified project-wide for all
devices communicating over
BACnet routers. So if a MS / TP

Protocol IPv6 which uses 16
octets for the address plus 2
octets for the port).
Example network
Figure 2 shows an example
network using four different
media: IP, LonTalk, MS / TP and
a PTP-connection to a foreign
BACnet / IP network. Router R1
and R2 appear in two networks
(R1 is in BACnet / IP network #45
and LonTalk network #998 while
R2 is in BACnet / IP network #45
and MS / TP network #65125).
Conclusion
The flexibility of BACnet sup­
porting multiple media allows costefficient usage of different media.
As always a good speci­fication and
documentation of the network in
a project is required. B-PAT or a
similar project database can help
keeping the overview.

Keep in touch
with the new Thermokon Thanos
Thermokon Sensortechnik GmbH is currently presenting
its new multifunctional room operating unit Thanos. With
this, the German company is pursuing a new path towards
intuitive and high design-oriented room control combined
with high quality and engineering Made in Germany.
Thanks
to
the
new
Thermokon Thanos an­
other top quality product
will be available in the
portfolio of room operating
units by the end of 2010.
Thanos is completing the
range of the current series
WRF04, WRF06, WRF07
WRF08
especially
and
convincing with its except­
ional design. Under an overall
glass front, a high-resolution
3.5”-TFT display is placed,
so that an optical display
of the executed functions
is shown with every input
made. Typical applications
for room automation can
be customized. The control
of HVAC elements such
as temperature set point
adjustment, blind and light
controls or fan stages can be
easily realized by a simple
touch. Combined with a
common operating structure,
the touch technology already
enables an intuitive operation
of the devices with its first
use. Thanos has an integrated
t e m p e r a t u r e / h u m i d i t y
sensor. The value is displayed
directly.
The new operating unit
Thanos is available in the
basic colors black and white.
With up to 12 buttons, a
larger version called “Thanos
L” is additionally available.
The lower operating area
is designed as a typical
rocking function. This type
is also available in landscape
version, model “Thanos
LQ”. Type “S” stands for
a smaller design unit. The
rocking function is realized
with a second menu level.
A brushed stainless steel clip
is designed as touch sensitive
presence
button
which
realizes a typical switch
function in the room.
The Thanos type “S” stands for a smaller
design unit. The rocking function is realized with a
second menu level.
Individual specifications are
also an important object
for the Thermokon Thanos.
Therefore, several button
fields can have a customized
legend. Via a software
application
the
devices
can be easily configured
with regards to operating
functions, button symbols
and display options.
The use of the standardized
BACnet MS / TP protocol
enables the connection to
corresponding distant ends
such as automation stations
or BACnet operating working
stations.
As an interface standard the
digital data transmission RS485 is used.
The device operates with the
BACnet Application Specific
Controller (B-ASC) device
profile and places a number
of BACnet objects at your
disposal. The addressing of
Thanos for identification in
the network is made via an
integrated DIP switch.
Optionally, the Thermokon
Thanos BACnet can be
extended with an EnOcean
based transceiver module.
Thereby, a gateway function
of BACnet to an energyoptimized EnOcean based
wireless system is realized.
Furthermore, a direct and
wireless communication to
EnOcean based acutuators
can be made. Possibilities and
applications are unlimited.
The new multifunctional
room operating unit Thanos
once again emphasizes the
high demand for design &
technology by Thermokon.

Universal Gateway
for BMS
Standard Protocols
Made in Germany.
Ruling the world.
Building Management Systems (BMS) are handling a
growing amount of information through several standard
protocols. A centralized solution is highly limited in term of
speed, evolution and performance. A better solution is to
decentralize field data management and serve information
to supervision through BACnet. doGate is a Building
Controller that acquires field information from several
protocols, proposes gateway function between protocols,
includes a scheduling engine and behaves as a BACnet
server to connect SCADA systems. It also proposes an
OPC interface.
doGate is a multi-protocol
data collector including
Scheduling, Gateways and
serving
information
to
BACnet. Nowadays quite a
few standards protocols coexist: BACnet, LonWorks,
KNX, M-Bus but also de
facto standards such as
Modbus, OPC ... Systems
are becoming multi protocol
and BACnet is the standard
to oversee information.
doGate embeds doMoov
– an operating system to
manage BMS standards –
and gets the benefit of the
entire enhanced functions of
that OS.
An improved data
acquisition server
for BMS Standards
BMS networks are becoming
larger and larger and the
amount of information to
acquire through an HMI or
a SCADA system is always
increasing. A good system has
to optimize data acquisition
and decentralize functions.
doGate allows such a
decentralized
acquisition:
it includes an innovative
multi protocol data server
engine (LonWorks, BACnet,
KNX, Modbus, M-Bus,
OPC). That multi thread
engine dramatically reduces
SCADA initialization time
and significantly improves
performances.
A true BACnet server
mapping every BMS
standard protocol
Field information has to
be forwarded to SCADA
system. BACnet is the real
interoperable standard way
to perform that important
operation. doGate proposes
an easy mapping from every
field data point coming from
any BMS standard protocol
to a native BACnet interface.
In case the monitoring
system does not support
BACnet,
doGate
also
proposes a standard OPC
server interface.
A universal BMS
gateway between
every field protocol
We
broadly
need
to
exchange
information
between field protocols and
doGate natively includes
that function. It includes
a connectivity platform
between the BMS Standards
protocols
(LonWorks,
BACnet, KNX, Modbus,
M-Bus,
OPC).
doGate
proposes a 1 to 1 or n to
n mapping. It embeds the
complete catalogue types and
manages standard types for
you. doGate also includes a
scheduling engine to manage
calendars and schedulers on
any data point.

Universal BACnet-Router
The UBR-01 supports routing between the three most
important BACnet layers IP, Ethernet and MS / TP but
additionally allows special infrastructure functions for
BBMD and Slave Proxy.
The UBR-01 is designed to
allow various routing and
infrastructure
functions
for BACnet combined in a
small box ready for cabinet
mounting.
The
routing
options
include BACnet / IP, MS / TP
acting as a master node
and
BACnet / Ethernet.
All three layers can be
activated separately. The
configuration and diagnostic
functions are provided by an
integrated web-server using
your preferred browser.
International language packs
can be uploaded as an option.
Project
documentations
can be uploaded, a total of
200MB free flash memory
is available to store any kind
of documents, even preferred
mp3 files if you like. All
factory help files are available
using the web-server as well.
The
integrated
DHCP
server
(=Dynamic
Host
Configuration
Protocol,
active only if specifically
set into this configuration)
allows dynamic address
provision e.g. for easy service
access.
The UBR-01 is a fully func­
tional B-ASC BACnet device
including DCC (= Device
Communication
Control)
and RD (= Reinitialize De­
vice) functionality. This al­
lows observing the device
using the standard BACnet
communication. The device
object properties like objectname, description, location,
etc. can be freely defined
using the web-server.
Network
Biasand
Termination resistors are
integrated and can be easily
activated by three separate
DIP-switches.
The UBR-01 is designed to allow various routing and infrastructure functions for BACnet here: Screenshot of UBR-01
shows a sample configuration.
22 BACnet Middle East Journal 2 11/10
Using BACnet / IP supports
BBMD (BACnet Broadcast
Management Device) and FD
(Foreign Device) operation
modes as well.
Using MS / TP automatic
slave detection and slave
proxy functionality can be
used to provide Dynamic
Device Binding on behalf
of slave nodes, which by
nature cannot support this
functionality.
Even
w / o
routing
functionality the UBR-01
may be used as a stand-alone
infrastructure component to
provide BBMD functionality
to the local sub-network
or to provide slave proxy
functionality for slave nodes
in a MS / TP network.
Conclusion:
The
UBR
is not only a powerful
BACnet router. This device
can be used for a variety
of applications acting as
a flexible infrastructure
component as well.
The device is available from
stock.
