Raising BACnet® to the Next Level

2

Our Approach to Building Automation

We believe all building automation devices including BACnet compliant

devices should be accessible from an IP Infrastructure.

3

Building Automation is Embracing IP Networks

4

Building Automation Network: Hierarchy

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.

5

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 IPnetworks

With structured wiring, the

prominent cabling is CAT 5. Fieldbus

wiring will become less attractive.

6

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 configurationA router is needed to view

BAS Remote web pages from the Internet.

7

BAS Switch – Plug & Play Ethernet Switch

Five 10/100 Mbps Ethernet ports Auto-negotiation and Auto-MDIX Intended for shallow panels 24 VAC/VDC powered DIN-rail or panel mounting

LED indicators show link, activity and data rate.

8

Skorpion – Plug & Play Switch

Five 10/100 Mbps Ethernet ports Auto-negotiation and Auto-MDIX Minimal DIN-rail space requirement 24 VAC/VDC powered DIN-rail mounting

Single-mode or multimode fibre optic versions are available.

9

Skorpion Managed – Ethernet Switch

Eight 10/100 Mbps Ethernet ports Auto-negotiation and Auto-MDIX SNMP protocol IGMP snooping with query Virtual LAN (VLAN) Quality of Service (QoS) RSTP or RapidRing®

cable redundancy Port mirroring, port

security & rate limiting Web page configuration 24 VAC/VDC powered DIN-rail mounting

Dual single-mode or multimode fibre optic versions are available.

10

Skorpion PoE Injector

Can fully power one Powered Device (PD) Mid-span Power Sourcing Equipment (PSE) Isolated 15.4 W power output IEEE 802.3af compliant 24 VAC/VDC powered DIN-rail mounting

This mid-span device will work with any 10/100 Mbps Ethernet switch.

11

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.

12

BAS Router: BACnet/IP to BACnet MS/TP

10/100 Mbps Ethernet port MS/TP EIA-485 port Opto-isolated EIA-485 transceiver Serial baud rate up to 76.8 kbps LED activity indicators on both ports 24 VAC/VDC powered DIN-rail mounted Web page configuration

Provides the means for accessing BACnet MS/TP devices from Ethernet.

13

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.

14

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.

15

BAS Router Enhancements

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

16

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.

17

BAS Remote – Versatile Web Appliance

BACnet/IP remote I/O Modbus TCP remote I/O Universal I/O points Relay output points Modbus TCP to Modbus

Serial router Modbus master to attached

Modbus ASCII or RTU Slaves 10/100 Mbps Ethernet port Web page configuration

The BAS Remote I/O count can be increased by adding expansion

modules

A 2-wire Modbus serial port provides access to a

wealth of Modbus I/O devices.

18

BAS Remote – Master Module

LED indicators relate the state of the I/O points

while identifying Ethernet activity.

BACnet/IP compliant B-ASC device profile 6 universal I/O points 2 relay outputs 24 VDC loop supply Modbus TCP Server Modbus serial gateway Expansion port 24 VAC/VDC powered DIN-rail mounted

19

Universal I/O − Analog Inputs

Voltage 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.

20

Universal I/O − Analog Outputs

Voltage 0-10 VDC 0-5 VDC 1-5 VDC 2-10 VDC

Current 0-20 mA 4-20 mA

Analog outputs source current to ground and

therefore no loop power supply is required. The output burden can be as

high as 750Ω.

Motorized actuators are typically used to position

dampers. Position feedback is sensed using an analog input on the

BAS Remote.

21

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.

22

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.

23

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.

24

Typical BAS Remote Wiring

25

Set-up is Accomplished Through Web Pages

26

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.

Expanding I/O Points in the Field

27

BAS Remote Expansion for Additional I/O

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

28

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.

29

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 noconvenient source oflow-voltage power

The BAS Remote PoE can still provide 24 VDC

power for field devices using a single PoE

connection.

Good for going Green!

30

BAS Remote Enhancements

Introduce control Sub-metering application Modbus-BACnet gateway Web Services Add more BACnet services

31

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.

32

Sedona Framework – Graphical Programming

Tridium’s Workbench can be used to program Sedona running in the BAS Remote.

33

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.

34

BAS Remote – Sub-metering Application

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

35

BAS Remote – Modbus to BACnet Gateway

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

36

BAS Remote – Web Services

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

37

BAS Remote – Add More BACnet Services

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
