Raising BACnet® to the Next Level
Our Approach to Building Automation
We believe all building automation devices
including BACnet compliant devices should be
accessible from an IP Infrastructure.
2
Building Automation is Embracing IP Networks
3
Building Automation Network: Hierarchy
4
We see three layers plus the Internet. Sensors and actuators at the bottom,
MS/TP and Modbus fieldbuses in the middle, and Ethernet at the top.
Our Strategy – Put Everything up on IP




Raising communication up to Ethernet is key to our strategy
Wireless would represent
the next step
PoE may become the
preferred method when
powering BAS devices in
the field
We produce automation
products that attach to IP
networks
With structured wiring,
the prominent cabling
is CAT 5. Fieldbus
wiring will become less
attractive.

Internet Connectivity

We can connect to the Internet with a Skorpion IP Router
 Four-port LAN-side switch
 WAN-side Ethernet port
 WAN-side DHCP client
 LAN-side DHCP server
 Port Address Translation
 Network Address Translation
 Port Forwarding
 Stateful Firewall
 PPPoE protocol for DSL
 Web page configuration
A router is needed to view BAS
Remote web pages from the
Internet.

BAS Router: BACnet/IP to BACnet MS/TP
In order to communicate between BACnet/IP and BACnet
MS/TP a special router is needed. A standard IP router will
not do. That is why we designed the BAS Router.
11



10/100 Mbps Ethernet port

Provides the means for
accessing BACnet MS/TP
devices from Ethernet.
12
BAS Portable Router
The same functionality as the BAS Router can be
gained in the BAS Portable Router which is
intended for connection to a laptop. It is useful
for troubleshooting and commissioning a BACnet
MS/TP network.
13
BAS Portable Router: BACnet/IP to BACnet MS/TP



Same functionality as the BAS Router
Receives power from a USB port on a laptop computer
Ideal for tools that commission or troubleshoot BACnet networks
Although powered from USB,
communication is through
Ethernet.

BAS Router Enhancements



15
Add BACnet/IP Broadcast Management Device (BBMD)
 Allows BACnet/IP systems to cross IP routers
 Receives Foreign Device Registration requests
Add support for BACnet/Ethernet to MS/TP routing
 Companies such as Alerton could use Ethernet and not IP
 This feature allows for a greater range of applications
Add support for BACnet/IP to BACnet/Ethernet routing
 Supports companies like Alerton with their BACnet/Ethernet
equipment
 Called a “one-arm router” since only one RJ-45 connector is used
BAS Remote – Versatile Web Appliance
One capability of the BAS Remote is that
it can function as a Modbus master to
attached Modbus serial devices such as
power meters and drives.

 0-10 VDC
 0-5 VDC
 1-5 VDC
 2-10 VDC
Current
 0-20 mA
 4-20 mA
Type II or III 10kΩ thermistor
The BAS Remote provides
a 24VDC loop supply to
power transmitters.

Voltage
 0-10 VDC
 0-5 VDC
 1-5 VDC
 2-10 VDC
Current
 0-20 mA
 4-20 mA
Motorized actuators are
typically used to position
dampers. Position feedback
is sensed using an analog
input on the BAS Remote.
Analog outputs source
current to ground and
therefore no loop power
supply is required. The
output burden can be as
high as 750Ω.
20
Universal I/O – Digital Inputs


Dry contact closure
Pulse inputs
Pulse input rates can be as
high as 40 Hz. A typical
application is meter reading
or flow rate measurement.
The BAS Remote will
accumulate counts or
determine pulse rate.
21
Relay Contact Outputs



Two form “C” contacts
Contacts rated at 2 A and 30 VAC/VDC
Intended for Class 2 circuits
In order to switch higher loads
or interface with Class 1
circuits, interposing relays are
required. However, with a 2 A
contact many loads can be
driven directly.
22
BAS Remote Power Requirements



24 VAC/VDC
10VA
Half-wave rectified power
Although half-wave rectified
power is less efficient, it
allows for the sharing of
power with other
equipment. Interfacing of
equipment is much easier
since most equipment is not
isolated from their power
source. With full-wave
rectified equipment, a
dedicated transformer is
required.
23
Typical BAS Remote Wiring
24
Set-up is Accomplished Through Web Pages
25
Expanding I/O Points in the Field
In order to increase the
I/O count without adding
another Ethernet drop, up
to three expansion
modules can attach to
one master module.
Communications between
master and expansion is
done through a
proprietary serial bus.
Master modules carry a BASR-8M part designation while
expansion modules are identified as BASR-8X.
26
BAS Remote Expansion for Additional I/O



27
Same I/O count as the
master – six universal I/O
and two relay outputs
Instead of a MB Modbus
serial gateway port there is
an UP port that connects to
the master
The DN port connects to
and next downstream
expansion module
The One-Cable Solution: Power over Ethernet
Simply make a connection
from a PoE compliant
Ethernet switch port to
the Ethernet port on the
BAS Remote.
Both the BAS Remote and field devices
can be powered from the data cable.
Saves from purchasing proprietary BAS
cabling and the associated cost of
installation. May gain you points towards
“green” certification.
28
BAS Remote PoE to Reduce Wiring



Same functionality as
BAS Remote Master
except no input power
requirement!
Used to promote our
“One Cable Solution”
Ideal when there is no
convenient source of
low-voltage power
The BAS Remote PoE can
still provide 24 VDC power
for field devices using a
single PoE connection.
29
Good for going Green!
BAS Remote Enhancements

Introduce control
Sub-metering application
Modbus-BACnet gateway
Web Services
Add more BACnet services
BAS Remote – Introduce Control

As a remote I/O device the BAS Remote cannot make control
decisions on its own. Control functionality can be gained by
incorporating Sedona from Tridium.
 Utilizes a graphical programming scheme similar to Niagara Framework
 We are allowed to market the product as Niagara Ready after a
certification process
 Allows customers familiar with Niagara the ability to implement
control loops within the BAS Remote
 No additional programming tools needed if the system integrator
already has Tridium’s Workbench
With Sedona, the BAS Remote can
communicate using the SOX protocol
with a JACE running Niagara Framework.
31
Sedona Framework – Graphical Programming
Tridium’s Workbench can be
used to program Sedona running
in the BAS Remote.
32
Building Controller Client Residing on Ethernet
You need a client such as a B-BC in the system
since the BAS Remote is only a server.
Fibre is recommended between buildings and copper within buildings.
33
BAS Remote – Sub-metering Application



34
Sub-metering will become an important application as owners bill
individual tenants for energy usage
Two ways of handling power measurement
 Pulse meters that provide a pulse per each unit of energy
 Modbus interface where calculations only need to be read
Modify the BAS Remote to directly handle sub-metering
 Incorporate the new BACnet object for meter reading
 Allow the customer to scale the meter through a web page
 Handle multiple pulse or Modbus meters
 Provide retentive memory in the event of a power outage
 Maintain profiles of common Modbus meters in memory
BAS Remote – Modbus to BACnet Gateway




35
Currently the BAS Remote can function as a Modbus TCP to
Modbus serial router
Add Modbus serial to BACnet gateway in order to allow Modbus
register to BACnet object mapping
Configuration through web page or product selection menu
Allows Modbus devices to be seamlessly treated as BACnet objects
such as BO, BI, AO and AI
BAS Remote – Web Services




36
BACnet is great for those familiar with building automation systems
but what about IT personnel?
Add web services functionality to the BAS Remote based upon
BACnet/Web Services
Allows IT personnel to access BAS data using XML
Investigate a competing web services technology called oBIX
BAS Remote – Add More BACnet Services



37
Add Foreign Device Registration which allows the BAS Remote to
communicate through IP routers
Add Change-of-Value (COV) that will allow the BAS Remote to only
report to a client any change in value of a point by more than a
preset amount
Add Read-Property-Multiple (RPM) which allows for more efficient
transfer of data
