international organization that develops guidelines and
certification procedures for L ON W ORKS products. Devices
that carry the L ON M ARK logo are able to interoperate even
if they are made by different manufacturers. Only devices
that adhere to the L ON M ARK guidelines and have passed a
conformance review may carry the L ON M ARK logo.
L ON W ORKS Message Application data contained within a LonWorks packet.
LonWorks messages are used to exchange data between
application devices on a L ON W ORKS network. A LonWorks
message includes a message code that identifies the type of
message. The interpretation of the remainder of the
message depends on the message type specified by the
message code. Also called a LonTalk message.
L ON W ORKS Protocol The protocol used on L ON W ORKS networks to standardize
communication between application devices. This protocol
is defined by the EIA-709.1 standard. Also called the
LonTalk protocol.
L ON W ORKS System A set of tools and components for implementing control
networks using the LonWorks protocol.
Message Code A message type identifier within a LonWorks message. The
message code identifies the message as an application
message, foreign frame message, network variable message,
network management message, or network diagnostic
message.
Message Tag
Input and output ports that devices use to send and receive
LonWorks messages.
Neuron Chip A family of VLSI components that implements the
LonWorks protocol. The Neuron Chip can manage I/O
devices and execute user-written application code, or
alternatively be used to create a network interface to a
host processor.
Network Services
Interface (NSI)
See LNS network interface.
Network Variable
High-level objects that application devices use to
communicate with one another. The types, functions, and
number of network variables in each device are
determined by the application code within the device.
Network variable update messages are a special type of
LonWorks message.
PCC-10 PC Card
LonTalk Adapter
The PCC-10 is a type II PC Card (formerly known as
PCMCIA) LNS network interface. It has an on-board
