format also specifies how data entered by a user or application is translated to the raw data to be
transmitted on a L
ON W ORKS network.
Network Variable/Configuration Property Types
A network variable or configuration property type defines the structure and contents of the 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 can be a standard configuration
property type (SCPT) or a user-defined configuration property type (UCPT)
Neuron Chip
A family of VLSI components that implements the Control Network Protocol. The Neuron Chip can
manage I/O devices and execute user-written application code, or alternatively it can be used to create
a network interface to a host processor.
Neuron Firmware
Firmware required to implement the ISO/IEC 14908-1 Control Network Protocol, I/O drivers, and
other system functions on a Smart Transceiver or Neuron Chip. This firmware is contained in the
VERxxx subdirectories of the L
ON W ORKS
images folder in files with the name S*.NX*. Other custom
firmware images are available for special purposes. Use of the Neuron Chip firmware is subject to
terms and conditions defined in the NodeBuilder and Mini software license agreements and the
L
ON W ORKS OEM license agreement.
Neuron ID
A 48-bit number assigned to each Neuron Chip at manufacture time. Each Neuron Chip has a unique
Neuron ID, making it like a serial number.
Network Explorer
An auto-hide window that displays a hierarchical view of your OpenLNS CT network and supports all
of the commands available within the drawing pages. The Network Explorer can be used in an
OpenLNS CT drawing as a navigational tool or as a network management tool.
Network Merge
Process in which one OpenLNS CT network design is merged into another existing network design.
Network Navigator
A dialog displaying a hierarchal view of the subsystems in a network that can be used to expand,
select, and deselect items when viewing or configuring an OpenLNS CT network.
Network Recovery
Process in which a new OpenLNS CT drawing and OpenLNS network database are created from an
existing L
ON W ORKS network. Network recovery is useful for networks that were installed with legacy
tools not based on OpenLNS, self-installed networks, and installed networks in which the OpenLNS
network database has been lost
Node Address
A unique 15-bit logical identifier for each device in a domain. The node address consists of two parts:
a 7-bit subnet address and an 8-bit Node ID. The Node ID is unique within the subnet.
Node ID
The third part of the LonTalk addressing hierarchy of domain/subnet/node. At installation time, each
device is assigned a unique node ID within its subnet by the OpenLNS Server.
