Automatic restart of the Easylon Link Power Supply at failures increases
the usability of the device. The possibility to set the type of bus termination by a switch is comfortable.
Link Power Networks
In Link Power Networks the twisted pair line not only transmits messages
but also supplies the devices. One link power supply can energize a bus
length of up to 320 m. For the network nodes a supply of 100 mA at 5 V is
available. Several link power segments can be connected. Concerning their
structure link power networks have to follow the rules for free topology
networks. Mixed networks with link power (TP/LP) and free topology (TP/
FT) transceivers can be realized.

Some Information About LonWorks
Some Information About LonWorks®
The Elements of LonWorks
LonWorks is a control network for universal use developed by
Echelon Corporation, USA. It is a distributed automation system
where free programmable intelligent nodes communicate using the
standardized LonTalk® protocol (CEA-709.1). The nodes exchange
status and control messages in any topology and via various media
realizing the desired control applications by interacting. Thereby
the entire system remains modular and flexible. Furthermore the
software of a node remains slight and manageable.
The Neuron Chip is the core of the node intelligence, where arbitrary
applications can be loaded. If required, external memory can be added.
Each Neuron and herewith each network node can be identified by its
unique, 48 bit Neuron-ID. In addition the Neuron ensures communication handling by the implemented LonTalk protocol.
Interoperability, meaning the seamless integration of products from
several manufacturers, is a major subject of LonWorks technology.
This was reached by using a single microprocessor –the Neuron Chip®–
not only providing a standardized communication interface but also
realizing the basic communication. Disclosure of the communication
protocol in the ANSI/CEA-709.1 standard and continuative standards
defined an open standardized system, for which components are
available from manufacturers all over the world.
Following the disclosure of the LonTalk protocol in the CEA-709.1 standard
it is possible to develop devices for this network technology using different
processors. Normally an FPGA or ASIC is used on the device to access the
network; the higher protocol layers are then realized in PC software. This
allows, further to higher performance, to overcome other resource restrictions. PC–network interfaces, routers and nodes with special performance
requirements are typical fields of application. The Easylon + products, for
instance, make use of these possibilities.
Network Nodes
What Makes the Difference?
The difference in comparison with other field bus systems becomes
obvious in the technological approach: Distributing the control task
by using rules partly realized in hardware is a general approach not
emerging from the solution for a single area of application. This results
in a universal usability for a general and very broad range of requirements. For extreme requirements and special challenges LonWorks
often is inappropriate. There specific solutions are unbeatable, however
rarely transposable.
In building automation this becomes apparent. LonWorks crosses
the traditional barriers between different building sections (heating,
lighting, …) to the advantage of a cross-functional building automation.
LonWorks devices complete the control tasks in their application
section but, at the same time, make available information to devices
dedicated to other application sections, thus increasing the effectiveness of the whole automation system. The important thing in this is
not being open for information transfer but the integrated operation of
the networked system. Without any change in technology all tasks can
be solved using products from different manufacturers. The message
from the access control at the gate is just a data point, which next to
granting access can as well be used by the room heating resulting in a
comfortable office temperature as soon as the staff member reaches
the office. Separate presence detection is not required. Initial costs
of such integrated solutions may be higher than those for traditional
ones, total cost of ownership will soon make up for it.
LonWorks Characteristics
• Standardized and already implemented communication
• Manageable software by distribution of the control task
• Easy modification and scalability
• Free choice of topology
• Safe local operation by independence from a central instance
• Variety of transmission media
• Communication distance
• Flexible addressing
• Interoperability
A transceiver couples the node to the network. As large as the variety of
the media is which LonWorks can use (the technology is by definition not
restricted to certain media) as large is the number of different transceivers. Very common is the FTT-10A transceiver, as twisted pair lines in free
topology are frequently used (TP/FT networks).
LonTalk Protocol
This is the LonWorks “language”. It is used with all nodes and is already
implemented in the Neuron Chip.

Some Information About LonWorks
Tools for Operation and Development
Network Topology and Media
A network management tool is required to design and maintain a LonWorks network. Almost all current tools are based on the LNS (LonWorks
Network Services) platform by Echelon. A network management tool
serves for planning the network and establishing the logical connections
between the nodes – the binding. Furthermore it allows network diagnosis
and provides information visualization systems can use.
LonWorks allows for various network topologies and free selection
between bus, star, ring or tree structure. In practice free topologies
often are realized, oriented to the existing structures in buildings or
installations. For segmentation of such free topologies routers can
be used to control the data transfer.
For the development of the nodes themselves Echelon provides the “NodeBuilder” software. This program allows application writing using the
Neuron-C programming language. Similar to C this language contains
special extensions with respect to the LonWorks communication protocol
and enables a quick implementation of control applications.
The standardized protocol in itself is not sufficient. Standard network
variable type tables (SNVT) are part of the LonWorks technology. With
respect to applications, LonMark International coordinates the definition
of functional profiles existing for many areas of application.
Bus (line)
Free Topology
The Network Structure
The LonWorks network can be structured in domain, subnet and node.
A domain can comprise up to 255 subnets, a subnet a maximum of 127
nodes. In total this makes up to 32 385 nodes in one domain. Several
domains can be connected. However, in principle only nodes within the
same domain can directly communicate. Each node in the network has a
distinct logical address consisting of the three hierarchical levels domainid, subnet-id and node-id.
A LonWorks network uses infrastructure components such as routers,
bridges and repeaters.
Routers are devices offering two or more network connections. They are
used to connect different subnets. Messages received from the network
on one side will usually be transmitted to the other
side and vice versa. Additionally the router can
filter messages, distribute messages or find and
route into the correct subnet.
Bridges connect different domains. They transmit
data from one domain to another and vice versa.
Repeaters just are physical signal amplifiers regardless of the message contents. They are used
to realize long communication distances or if the
maximum permissible number of 64 nodes per
2-wire-segment (FTT-10 transceiver) is exceeded.
LonWorks is specially flexible with respect to the transmission media:
• Twisted pair
• Radio
• Infra-red
• Fiber optic cable
• COAX cable
• Power supply system
• IP-networks
Even larger distances can be connected. Networks (in bus topology)
can be extended up to more than 2000 m using twisted pair lines.
By using physical star couplers for instance, the length of the individual branch lines is 1.3 km maximum. By using repeaters, routers or
gateways the structures of the network can be extended to an almost
unlimited length. Further to those transmission media the LonTalk protocol can also use
the IP-protocol for transmission. Thus the LonTalk protocol becomes
Intranet and Internet enabled.

Some Information About LonWorks
Who is Addressing Whom?
The Network is the Control
Further to the mere physical connection the control task requires
a logical connection. Data exchange in LonWorks networks takes
place between network variables (NV). A special group among these
is the SNTVs (Standard Network Variable Type). Defined by LonMark
International every developer can use them to maintain interoperability. Network variables are of special importance:
A LonWorks network consists of up to 32 385 intelligent network nodes
communicating via LonTalk. Time-critical messages can be prioritized; a
safe transmission is granted, amongst others, by end-to-end control and
• Information from one node to another is exclusively “transmitted” by NVs.
• NVs are the logical interface from one node to every other node.
• Binding the NVs of the network nodes is the main task of the
system integrator while commissioning the network.
• NVs are, along with configuration parameters, the essential
information, which can be seen of a node.
A network management tool is used to define the control logic of the
network. The following definitions are made:
• Who communicates with whom?
• Which information is exchanged?
• In which way is the information exchanged?
Wherever input and output signals (I/O) are required, distributed and
intelligent sensor or actor devices can be placed. Those application specific nodes control and manage themselves and mutually. They only need
status or modification messages from other network nodes to take action,
which they receive via the LonWorks network. Transmission speeds up
to 1.25 Mbps can be reached.
Standardized data types, so-called SNVTs and functional profiles are the
basis for the interoperability of the network nodes. The interoperability
between modules from different vendors provides the user with freedom of
choice and considerably facilitates a cross-functional building automation.
By distributing the intelligence or, respectively, the application LonWorks
networks can be operated at low cost without host computer or PLC (for
central capturing and processing). No host computer is required for control
and monitoring tasks. For visualization purposes and further processing
of LonWorks data in other systems usually PCs are used.
LonWorks offers a flexible field bus system provided with distributed intelligence that can cover
large distances using most different media on a
high level of reliability and safety. The modular
structure allows for modification and extension of
the network; at any time and without large effort.
