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 L
ON-
W ORKS 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 L ON W ORKS network. The most widely used tool is the LonMaker Inte-
gration 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.
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. For details about the func-
tional 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 L ON W ORKS network 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 net-
work 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 L
ON W ORKS device through the network. Then use the Neuron ID (hexadecimal 12-
digit number) contained in the Neuron Chip to identify the download destination device. The SX5L communication termi-
nal is attached with a label indicating the Neuron ID. The Neuron ID can also be sent to the network by pressing the SER-
VICE REQUEST button on the SX5L.
(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.
