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 IP networks 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 configuration A 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 10k Ω 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 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. 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
