3 Nowadays, BAS/BMS involves knowledge of many disciplines. Controls Engineering HVAC Engineering Computer Science Communication Engineering Keyword: Communicate
4 Basic Concepts Architecture (computer) [ A design. The term architecture can refer to either hardware or software, or to a combination of hardware and software. The architecture of a system always defines its broad outlines, and may define precise mechanisms as well. An open architecture allows the system to be connected easily to devices and programs made by other manufacturers. Open architectures use off-the-shelf components and conform to approved standards. A system with a closed architecture, on the other hand, is one whose design is proprietary, making it difficult to connect the system to other systems.
5 Basic Concepts A system architecture is the design or set of relations between the parts of a system It can best be thought of as a representation of an existent (or to be created) system, and the process and discipline for effectively implementing the design(s) for such a system. The set of relations (that is, embedded information) which h an architecture describes may be expressed in hardware, software, or something else
6 Basic Concepts Terminology & definitions See more info on [ Online dictionary for computer and Internet definitions Data communication standard by ISO (International Organization for Standardization) di i Open Systems Interconnection (OSI) reference model provides the guidelines for DDC systems and electronic system communications

9 OSI Seven-layer Model Level 1 Physical Layer Defines physical/actual hardware connections Purpose: electrical interconnection (e.g. wire ) Services: media-specific details, transceiver type Level 2 Data Link Layer Defines local network access methods Purpose: media access and framing Services: framing, data encoding, media access, error checking
10 OSI Seven-layer Model Level 3 Network Layer Defines destination addressing Purpose: destination addressing Services: destination addressing, packet routing Level 4 Transport Layer Defines status & two-way communication Purpose: end-to-end reliability data transfer Services: acknowledgments, service type, duplicate detection, flow control
11 OSI Seven-layer Model Level 5 Session Layer Defines types & quality of services Purpose: remote actions Services: dialogue, remote procedure calls, connection recovery Level 6 Presentation Layer Defines, coverts & decodes messages Purpose: data interpretationi Services: network variables, application messages, foreign frames
12 OSI Seven-layer Model Level 7 Application Layer Defines application network service Purpose: application program Services: standard objects & types, file transfer, network service

20 OSI Seven-layer Model How to remember the 7 layers of OSI model? All People Seem To Need Data Processing Please Do Not Throw Sausage Pizza Away
21 Key Issues DDC control system architecture: key issues Topology ( 拓 撲 ) Geometric layout (physical or logical) of the wiring between participating nodes Protocol ( 協 定 ) Agreed-upon format or standard Such as the network access method (data link layer) Mdi Media ( 媒 體 ) Physical/actual communication medium (wiring) Such as twisted pairs (TP) cable
22 Topologies or layout of control network
23 Key Issues Topologies (physical wiring) Bus topology Star topology Ring topology Free/hybrid topology What are the benefits of each? Which one is more reliable? Why?
24 Key Issues Network access method (NAC), data link layer Master/slave protocol (client/server) An architecture in which one device (the master) controls one or more other devices (the slaves) Peer-to-peer protocol (or P2P) Each workstation has equivalent capabilities and responsibilities Connection type (collision detection) Used dby Ethernet tlan standards d Token-passing type Used by ACEnet
25 Master-slave method Peer-to-peer method token-passing type
26 Key Issues LAN (local-area area network) standards Ethernet ISO by Digital Equipment Corp., Intel Xerox Peer-to-peer connection: e.g. carrier sense multiple access w/ collision detection (CSMA/CD) Speed: 10 to 100 Mbps ARCNET Developed dby Data Point tcorp. Star or bus topology, peer-to-peer token-passing Speed: 2.5 Mbps
27 Carrier Sense (CS): Before a system can start transmitting on a Network, it 'listens' on the cable for a carrier signal (very much the same as when you pick up the phone and listen to the dial-tone). Only when the cable is not busy with another data-transfer, it will start the transmission. Multiple Access (MA): As long there is no 'busy-signal signal' on the cable, any connected station can start transmitting immediately.
28 Collision Detection (CD): It can happen, that 2 or more stations start transmitting at the same time, which causes then a collision of the signal, which is then detected causing the transmitting systems to abort, wait a little (length is randomly determined) before the systems try to access the network cable again.
29 Key Issues Physical layer standards For data transfer between components Three common standards: Electronic Industries Associations Standard EIA-232 or RS-232 (RS = recommended standard) Up to 20 Kbps; max. 15 m wiring EIA-485 or RS-485 Three wire, polarity-sensitive transceiver FTT: Free Topology Transceiver Two-wire, wire unshielded, polarity insensitive transceiver
30 Key Issues Physical media Twisted pairs (TP) Twisted shielded d pairs (TSP) Coaxial cable Fibre optic cables Power line carrier (PLC) Rarely used in HVAC DDC because of noise & speed (* More info in the Networking lecture)
31 Key Issues Examples: DDC Online [ Architecture diagrams, e.g. Honeywell: Excel 5000 Johnson Controls: Metasys M-Series Siemens APOGEE Solidyne: IZAC Control and Monitoring System Product details
32 Interoperability Definitions The ability of software and hardware on different machines from different vendors to share data. [wedopedia.com] The ability of two or more systems or components to exchange information and to use the information that has been exchanged [from IEEE] The ability of equipment to work together & communicate mutually [see journal article in references] Between een different manufacturers control equipment Different versions of control equipment Equipment for different purposes (HVAC, fire, lights)
