Review

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

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

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

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

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

Network Variables

• The dynamic data sent or received by network devices

• Signal-type independent – temperature, pressure, volume, flow, etc.

• SNVT’s are standard network variable types as defined by the LonMark organization Known and documented structure,

size, range, etc.

• UNVT’s are manufacturer defined Tools may require resource files to

document data format

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

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 LAN’s and WAN’s

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

Demonstration: A Simple LONWORKS Network

• Create a simple LONWORKS network

• Review basic LONWORKS terminology

LonWorks Architectures

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

PortableNetwork Management Tool

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

LNS Application andLNS Server PC

Remote Client Applications

• 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

LonWorks Topologies

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

T T

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

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
