Channel
The physical media between devices upon which the devices communicate. The LonTalk protocol is
media independent; therefore, numerous types of media can be used for channels: twisted pair, power
line, fiber optics, IP, and RF, and other types.
Clock Multiplier
For 5000 Series chips, you can select the frequency at which the Neuron Chip runs to modify the
internal system clock speed. You can select multipliers of ½, 1, 2, 4, and 8 to adjust the internal
system clock speed from 5 MHz to 80 MHz (based on a crystal running at 10 MHz).
Commissioning
The process in which the LonMaker tool downloads network and application configuration data into a
physical device. For devices whose application programs are not contained in ROM, the LonMaker
tool also downloads the application program into non-volatile RAM in the device. Devices are usually
either commissioned and tested one at a time, or commissioned and then brought online and tested
incrementally.
Code Wizard Template
Defines the general infrastructure and layout of a Neuron C application generated with the
NodeBuilder Code Wizard. Code templates supply many utility functions for managing device and
functional block status, which you can use in your application, as needed.
Configuration Properties (CPs)
Configuration properties define the behavior of an application device by determining the manner in
which data is manipulated and when data it is transmitted. Configuration properties can be applied at
the device, functional block, or network variable level. Configuration properties determine the
functions to be performed on the values stored in network variables. For example, a configuration
property may specify a minimum change that must occur on a physical input to a device before the
corresponding output network variable is updated.
Configured
A device state where the device has both an application image and a network image. This indicates
that the device is ready for network operation.
Connector Shape
A single connector used to connect a pair of network variables within the same subsystem.
Control Network Protocol (CNP)
Echelon’s implementation of the ISO/IEC 14908-1 standard. The CNP provides a standard method for
devices on a LonWorks network to exchange data. The CNP defines the format of the messages being
transmitted between devices, and it defines the actions expected when one device sends a message to
another. The protocol normally takes the form of embedded software or firmware code in each device
on the network.
Data Point
A network variable, configuration property, or functional block state (enabled or in override) that the
LonMaker tool can monitor and/or control.
Data Point Shape
A shape in the LonMaker Basic Stencil of the LonMaker tool that you can use to monitor and control
the values of network variables and configuration properties, and the states of functional blocks
(enabled or in override).
