PREFACE-2SX5L COMMUNICATION TERMINAL USER’S MANUAL
This chapter describes general information about the LONWORKSnetwork system and provides the features and functions
of the SX5L communication terminals.
LONWORKS Network
LONWORKS refers to the whole multi-purpose network technology de veloped by Echelon Corporation to provide solutions
for building and home automation, industrial, transportation, and public utility control networks. LONWORKS is a fieldlevel open network that enables to build open, multi-vendor control systems of the peer-to-peer distributed control configuration.

Example of LONWORKS Network for Building Automation (BA)
In the above control system, LONWORKS devices are connected to the LONWORKS network, such as air-conditioner, control valve, digital data loader, thermometer, fluorescent light, blind, illumination meter, intrusion detector as well as SX5L
communication terminals. These LONWORKS devices contain a microprocessor called Neuron Chip and a LONWORKS
transceiver to communicate with other devices using the LonTalk protocol.
In the centralized control system, the network consists of one host controller, such as a PLC or computer, and multiple terminals, such as sensors and actuators, connected in the 1:N configuration. The host takes care of almost all processing for
intended control operations while terminals work as instructed by the host through the network communication. Therefore,
the host alone contains the control program and network settings.
In contrast to the centralized control system, LONWORKS is a distributed control system with each device containing an
application program. Operation of each device can be programmed by changing configuration parameters. The destination
and contents of communication can be designated for each device using a network management tool.

LONWORKS Device and Functional Block
The following figure illustrates examples of LONWORKS devices. Device A consists of switches to send the ON/OFF status
signals of three switches to the network when they are operated. Device B consists of two lamps which go on or off when
receiving ON/OFF signals from the network.

network to send the operation results and receive commands is the network variable.
In the next figure, the operation performed by device A is represented by functional block A, which contains three network
variables to send the statuses of three switches. The operation performed by de vice B is represented by functional block B,
which has two network variables to receive commands to turn on and off the lamps. Network variables to send data are
called output network variables, and those to receive data are input network variables.
When network variable D is designated as the destination of network variable A, it is made possible for the device A
switches to turn on or off the device B lamps. This procedure is called binding.

Standard Network Variable Type and Standard Configuration Property Type
As shown in the figure of the example of LONWORKS Network on the preceding page, the LONWORKS network can deal
with various types of data in addition to ON/OFF statuses, such as angle, temperature, illuminance, voltage, and current.
Unlike other field-level networks which transmit data without physical units, LONWORKS can send data with physical
units. The LONMARK Interoperability Association defines Standard Network Variable Types (SNVTs) to facilitate interoperability by providing a well-defined interface for communication between devices made by different manufacturers. The
association also defines Standard Configuration Property Types (SCPTs) to further facilitate interoperability by providing
a well-defined compact mechanism for handling large amounts of configuration information on a device
Address and Table
The LonTalk protocol usually uses a combination of domain ID, subnet ID, and node ID to identify the address of the
receiving device. Each L
store the addresses to send data to (destination addresses). All SX5L communication terminals can store 2 addresses in the
domain table and 15 addresses in the address table, or the maximum quantities allowed for a LONWORKS device.
To identify each network variable contained in a L
selector address. Mutually bound network variables are assigned the same selector address. When the value of a network
variable is sent to multiple network variables, the network variable of the transmitting device sometimes require another

place, called an alias table, to store the second and subsequent selector addresses. The allowable quantity of selector
address entries for the alias table depends on the type of the device. The maximum quantity is 62 according to the LON-
WORKS specifications. For the quantity of address table entries of the SX5L, see page 4-1.
When using the LonMaker Integration Tool for binding, the tool automatically assigns the selector addresses. Therefore,
users do not have to consider the selector addresses. However, if the device use up the alias table and more binding is
attempted, the tool indicates an error. The network must be designed to keep the selector address quantity within the alias
table entry capacity.
Network Building Procedures
A network management tool is needed to build a LONWORKS network. The most widely used tool is the LonMaker Integration Tool from Echelon. The basic procedures are illustrated below. For detailed procedures, see the user’s manual for
each tool you use.
(1) Understand the functionality of the device.
Confirm the built-in functional blocks and network variables to understand the functionality.
(2) Determine device arrangement (addresses).
A management tool is available which automatically assigns an address when a device is placed.
(3) Place functional blocks and bind network variables.
Connect the transmitter and receiver for each network variable.
(4) Download the programmed network configuration to corresponding devices.
Identify devices by their Neuron ID and write the configuration data to the devices.

Network Building Procedures
(1) Understand the functionality of the device.
Before proceeding with building the network, it is necessary to understand the types and quantities of functional blocks
contained in the device you are using, the details of the functionality, and the network variables. F or details about the functional blocks contained in the SX5L, see Chapter 4: Software Specifications.
(2) Determine device arrangement (addresses).
From this step, a network management tool is used. The LONWORKSnetwork identifies the logical location of a device by
its domain ID, subnet ID, and node ID. The LonMaker Integration Tool automatically assigns these three IDs when a
device symbol is placed on the data base. For step (2) and after, the information about the device must be sent to the network management tool. One method is using a XIF file, and another is uploading from the device through the network.
(3) Place functional blocks and bind network variables.
As shown in the figure of functional blocks on the preceding page, bind network variables as many as required for the
entire network. Generally, steps (2) and (3) are performed offline.
(4) Download the programmed network configuration to corresponding devices.
Connect the network management tool to the network, and download the information concerning addresses and binding
specified in steps (2) and (3) to each LONWORKS device through the network. Then use the Neuron ID (hexadecimal 12digit number) contained in the Neuron Chip to identify the download destination device. The SX5L communication terminal is attached with a label indicating the Neuron ID. The Neuron ID can also be sent to the network by pressing the SERVICE REQUEST button on the SX5L.

SX5L Communication Terminal Models and Features
The SX5L is a terminal block type LONWORKS I/O device available in a variety of models designed for multi-vendor
building automation and industrial control networks.
All SX5L communication terminals contain Standard Network Variable Types (SNVTs) defined by the L
Interoperability Association.
Output network variables can be made to be sent only when the input status changes in order to reduce the network traf fic,
and also can be made to be sent at regular intervals (heartbeat) while the input status does not change.
When the network is powered up, each node sends the initial values of the output network variables at different timing.

Finger-safe Spring-up Terminal Block Features
Time saving
The innovative terminals on the SX5L series use special,
spring-loaded screws. This makes installation as easy as pushing down and turning with a screwdriver. Installation time is
cut in half since the screws do not need to be backed out to
install wiring.
Screw terminals accept bare wire or ring or spade connectors.
Finger-safe
The screws are held captive once installed and are 100% fin-
ger-safe.

screw.
Insertion pin
Detachable
The terminal block can be removed simply by squeezing both
latches on top of the block inward to unlock the block from
the socket. To reattach the terminal block, place the block in
the socket with the latches opened and press the block until it
bottoms in the socket, then the latches snap outward to lock
the terminal block.
Wiring can be done with the terminal block removed, so
installation in narrow areas is quite easy. When replacing the
SX5L modules, simply remove the terminal blocks and reinstall the terminal blocks into the new SX5L module, without
disconnecting wires.
Insertion pins
Insertion pins are positioned on the base of the terminal block
and inside the socket to prevent insertion of invalid terminal
blocks into the socket. The pins are keyed to make sure of
correct matching of terminal block and socket, and to prevent
swapping of upper and lower terminal block.
