Kinds of Control Algorithms

• Master/Slave
• a single controller making all the control
  decisions
• Single point of failure
• Difficult to expand
• Costly to install more wiring needed to connect
  sensors and actuators
• Proprietary programming
• Proprietary solutions

14
Kinds of Control Algorithms

• Peer-to-Peer
• Distributed control intelligence
• No single point of failure
• Easy to expand and add more devices
• Less costly wiring installation
• No home I/O wiring runs

15
Open and Independent

• Robust, reliable, proven device networking
  protocol on a chip
• Manufacturers of smart devices can get to market
  quickly
• End users no longer locked into single supplier
• Integrators can choose best of breed devices
• LonTalk is media independent
• LonWorks tools operate on multiple platforms
• Multi-industry standards group ensure
  interoperability

16
Look for the LONMARK Label300 members from 17
countries ensuring plug-and-play operation

• Non-profit industry association
• Includes manufactures, integrators, application
  developers, and end-users
• Establishes technical guidelines
• Industry specific task groups
• Promotes the LONMARK standard and certifies
  product conformance
• Provides a resource of device information
• Governed by board of directors made up of
  industry members
• Includes sponsor members and elected
  representatives
• All members have a vote

17
Networking Technology

• Allows integration of device information across
  network of any size including the internet
• Requires the assignment of a logical identity for
  each device called the Domain/subnet/node address
• Assigned by the network management tool
• Allows message packets to be isolated or
  forwarded by intelligent LonWorks routers

18
LONWORKS Network Elements
Device
Network Tool

• Channel
• Media to which devices are connected

• LonMark Certified
• Network Tool
• Installation tool
• Human machine interface (HMI)

Channel
19
LonTalk Protocol

• Globally recognized standard ANSI/EIA 709.1

• Network Variables

• Network Management

• Message Service

• Addressing Routing

• Media Access

• Physical Connection

Physical Media
20
Network Variables

• The dynamic data sent or received by network
  devices
• Signal-type independent temperature, pressure,
  volume, flow, etc.
• SNVTs are standard network variable types as
  defined by the LonMark organization
• Known and documented structure, size, range, etc.
• UNVTs are manufacturer defined
• Tools may require resource files to document data
  format

21
Configuration Properties

• Define device behavior such as setpoint, high
  limits, throttle, etc.
• SCPTs are standard configuration property types
  as defined by the LonMark association
• Known and documented structure, format, range,
  etc.
• UCPTs are manufacturer defined
• Tools may require resource files to present
  values in a meaningful way.

22
LNS? is LonWorks Network Services

• Network management platform
• Foundation for open interoperable networks
• Provides a core set of management tools and
  connectivity options
• Client/Server architectures
• Supports configuration tools from multiple
  vendors
• Provides access to any point of network
  information from any point on the planet

23
LonWorks is about Distributed Control
Intelligence

• Many small devices sensors, actuators,
  controllers
• Each containing a microprocessor that implements
  the LonTalk protocol
• Each device subdivides control functionality into
  objects called functional blocks
• Could be I/O, controller, or system wide
  functions
• Each device sends/receives small message packets
  that contain control data
• Can create large, powerful, and flexible networks
  across LANs and WANs

24
LonWorks Network Program

• The network image is a collection of configured
  devices and their associated connections (aka
  network variable bindings)
• A network management tool is required to
  configure device behavior and to define the
  network variable connections
• When the tool is finished it can go away!
• LonWorks uses an event driven control process

25
Demonstration A Simple LONWORKS Network

• Create a simple LONWORKS network
• Review basic LONWORKS terminology

26
LonWorks Architectures

27
Simple Device Network

• Devices communicate with each other directly
• No network tool required after commissioning the
  devices
• Tool is required to perform network maintenance
  such as adds/moves/changes or device replacement

Portable Network Management Tool
28
Local Client Applications

• LNS database resides on same PC as the network
  tool
• LNS communicates to devices via network interface
  hardware and/or software
• Twisted Pair, Powerline, IP

Remote Client Applications
LNS Remote Client Application

• Remote client is an application that runs other
  than on an LNS Server PC
• LNS Database is accessed over the network media
  or over IP
• It can be attached to any LONWORKS channel,
  including a LONWORKS/IP channel
• Requires the LNS Server application running at
  the PC where the LNS database resides
• The LNS Server application supports up to 100
  clients and 255 LNS databases opened
  simultaneously

30
Web Based Monitoring and Control Clients

• Any PC that can support a standard web browser
  interface
• Internet Explorer, Netscape, Etc.
• Network data served up as HTML web pages from
  LonWorks webserver device
• ILON100, iLon1000, Plexus, etc
• Can perform monitoring and control of network
  variables but cannot perform network management
  functions

Netscape or Internet Explorer running at remote
client
31
Internet/Intranet IP Backbone

• Internet to LonWorks routers (i.LONs) can be used
  to create one network by connecting remote
  locations over LONWORKS/IP channels
• LNS Server is not required for day-to-day
  operation
• up to 40 i.LON routers per LONWORKS/IP channel
• Time server may be required to synchronize
  message delivery across wide area networks

LonWorks Topologies

33
Bus Topology

• A physical routing of the communication channel
  that includes a distinct beginning and end
• Must be doubly terminated at beginning and end
• Device to device wiring or short stubs
• Easiest to troubleshoot
• Difficult to expand when you need to add more
  devices

34
Free Topologies

• A flexible wiring structure of the communication
  channel that includes a ring, star, loop, or
  combination
• Can have long stubs to devices and tools, tap in
  anywhere on the channel
• Difficult to troubleshoot
• Easy to expand
• Easy to exceed media limits
• Requires one terminator installed anywhere on the
  channel segment

T

35
Backbone Topology

• Connects routers to a common backbone channel
• Typically installed in a bus topology and
  includes mostly routers, network tools, and
  systemwide control devices
• Can be high speed twisted pair XF1250
• Can be high speed IP channel
• Reserves bandwidth for network tools
