Appendix B – Glossary

devices use network variables to communicate with one another since they are interoperable and
produce more efficient code. Message tags are similar to network variables except that they do not
have pre-defined types.

Monitor Set

A group of data points that OpenLNS CT uses to monitor and control network variables or message
tags.

Monitored Connection

A connector SmartShape or reference connection on which network variable values are displayed and
updated.

Network Configuration

The process of converting a network design into the data elements required by the Control Network
Protocol in each device of the network. This includes:

• Assigning domain ID and logical addresses to all devices and groups of devices.
• Binding network variables to create logical connections between devices.
• Configuring the various Control Network Protocol parameters in each device for the desired

features and performance, including channel bit rate, acknowledgement, authentication, priority
service, etc.

Network Image

A device's network address and connection information. For Neuron Chip hosted devices, the device's
network image is stored in EEPROM on the Neuron Chip. For host-based devices, the entire network
image except the network variable configuration table is stored in EEPROM on the Neuron Chip.

Network Interface

A L

ON

W

ORKS

device that provides a layer 6 LonTalk interface to an external host computer such as a

computer or a handheld maintenance tool. Network interfaces include IP-852 interfaces (SmartServer,
i.LON 100 e3 Internet Server, and i.LON 600 IP-852 Router); U10/U20 USB network interfaces; and
PCC-10 and PCLTA-10, 20, and 21 PCI network interface cards.

Network Service Device (NSD)

A device representing a local or remote client that connects the client to the L

network.

Network Services Interface (NSI)

The component in the OpenLNS architecture that provides the physical connection to the L

ON

W

ORKS

network, manages transactions with the NSS, and provides transparent remote access to the NSS.

Network Services Server (NSS)

The component in the OpenLNS architecture that processes network services, maintains the network
database, and enables and coordinates multiple points of access.

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 Format

The network variable or configuration property format specifies how the raw data contained within a
network variable or configuration property is translated for display or for use by an application. The
