Echelon IzoT NodeBuilder - Manual (Page 274)

Device
A device that communicates on a L ON W ORKS network. A device may be an application device,
network service device, or a router. Devices are sometimes referred to as nodes in L ON W ORKS
documentation.
Device Interface
The logical interface to a device. A device’s interface specifies the number and types of functional
blocks; number, types, directions, and connection attributes of network variables; and the number of
message tags. The program ID field is used as the key to identify each external interface. Each
program ID uniquely defines the static portion of the interface. However, two devices with identical
static portions may differ if dynamic network variables are added or removed, or if the types of
changeable network variables are changed. Thus it is possible to have devices with the same program
ID but different external interfaces.
Device Interface File (XIF)
A file that documents a device’s interface with a network. The file can be a text file (.XIF extension),
or it can be a binary file (.XFB extension).
Device-Specific Configuration Property
A configuration property that has values that can be modified independent of the network database.
Changes made to a device-specific configuration property are not updated in the network database.
Device Template
A device template contains all the attributes of a given device type, such as its functional blocks,
network variables, and configuration properties. You can create a device template by importing a
device interface (XIF) file supplied by the device manufacturer, or by uploading the device interface
definition from the physical device. A device template is identified by its name and its program ID.
Both must be unique within a network—you cannot have two device templates with the same name or
the same program ID in a single network.
Download
An installation process in which data, such as the application program, network configuration, and/or
application configuration, is transferred over the network into a device.
Free Topology
A connection scheme for the communication bus that removes traditional transmission line restrictions
of trunks and drops of specified lengths and at specified distances, and terminations at both ends. Free
topology allows wire to be strung from any point to any other, in bus, daisy chained, star, ring, or loop
topologies, or combinations thereof. It only requires one termination anywhere in the network. This
can reduce the cost of wiring by a factor of two or more.
FT 5000 EVB
A L ON W ORKS evaluation board that uses Echelon’s FT 5000 Smart Transceiver. It features a compact
design that includes the following I/O devices that you can use to develop prototype devices and run
the FT 5000 EVB examples: 4 x 20 character LCD display, 4-way joystick with center push button, 2
push-button inputs, 2 LED outputs, digital light sensor, and digital temperature sensor.
FT 5000 Smart Transceiver
A chip that integrates a Neuron 5000 processor core and a TP/FT-10 transceiver. See Neuron 5000
Processor for more information about the key features of the Neuron 5000 processor.
