A network of intelligent devices (such as sensors, actuators, and controllers) that
communicate with each other using a common protocol over one or more communications

channels.

technology consists of the tools and components required to build intelligent device and

to install them in control networks.
Mandatory Network Variable/Configuration Property

A network variable/configuration property that must be implemented by the functional

block, as specified by the functional profile that the functional block is instantiating.
Mini FX Evaluation Kit

A tool for evaluating the development of control network applications with the ISO/IEC

14908-1 standard. You can use the Mini FX to develop a prototype or production control

system that requires networking, particularly in the rapidly growing, price-sensitive
mass markets of smart light switches, thermostats, and other simple devices and

sensors. You can also use the Mini FX to evaluate the development of applications for

such control networks using the L

Mini Gizmo I/O Board
A board that can be connected to a PL 3150 or 3170 EVB. The Mini Gizmo I/O board
contains the following I/O devices for testing device application running on a PL EVB:

eight push buttons, eight LEDs, a temperature sensor, and a piezo buzzer.
Monitored Connection

A network variable connection in which the current values are being monitored, typically

by an HMI. The connector shape and reference connection in a LonMaker drawing

demonstrate monitored connections.

Network Variable (NV)

Network variables allow a device to send and receive data over the network to and from

other devices. Network variables are data items (such as temperature, the state of a

switch, or actuator position setting) that a particular device application program expects
to receive from other devices on the network (an input network variable) or expects to

make available to other devices on the network (an output network variable).

Network Variable/Configuration Property Types
A network variable or configuration property type defines the structure and contents of a

data object. A network variable type can be either a standard network variable type
(SNVT) or a user-defined network variable type (UNVT). A configuration property type
