Channel Segment
A portion of a channel. A single segment can be comprised of multiple sections connected by physical
layer repeaters.
Channel Type
Channels are categorized into channel types, which are characterized by the device transceiver.
Common channel types include the following: TP/FT-10 (ISO/IEC 14908-3 twisted pair free topology
channel), TP/XF-1250 (high-speed twisted pair channel), PL-20 (ISO/IEC 14908-2 power line
channel), FO-20 (ANSI/CEA-709.4 fiber optics channel), and IP-852 (ISO/IEC 14908-4
IP-communication).
Client/Server Architecture
In a L ON W ORKS network, the OpenLNS Server provides a set of directory, installation, management,
monitoring, and control services for computers running IzoT Commissioning Tool and other OpenLNS
tools, applications, and plug-ins (clients). The client/server architecture of OpenLNS allows multiple
users running OpenLNS tools, applications, and plug-ins on separate computers to access the
OpenLNS Server simultaneously. This means that managers, system integrators, installers, and
maintenance personnel can all work on the same L
ON W ORKS network at the same time.
Commissioning
The process in which IzoT Commissioning Tool determines and downloads network and application
configuration data into a physical device. For devices whose application programs are not contained in
ROM, IzoT Commissioning Tool can also download the application program into non-volatile memory
in the device. Devices are usually either commissioned and tested one at a time, or commissioned and
then brought online and tested incrementally.
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.
Connection
The implicit addressing established during binding. A connection links one or more logical outputs
(network variables or message tags) to one or more logical inputs. A connection may be represented
with a connector SmartShape or a reference connection.
Connection Description
A set of properties, namely the message service type and addressing mode, that apply to a network
variable connection.
Connector Shape
A single IzoT Commissioning Tool connector used to connect a pair of network variables (or message
tags) within the same subsystem.
Controller
A high-level component that takes one or more sensor values and selects an appropriate setting on one
or more actuators to achieve a desired function.
