390 Appendix G – Glossary
LonMaker tool OnNet. If the LonMaker tool is OffNet and attached to the network, you can still
perform read operations on the network.
OnNet
A management mode in which network configuration changes are propagated immediately to the
devices on the network.
Override
A management command used on a functional block that causes output network variables to send their
configured override values. The override values are set using the configuration properties in the
functional block. The override values are sent even if part of the network is not yet operating or there
is no input to the functional block.
Passive Configuration Mode
A mode in which changes to configuration property values are manually propagated to one or more
devices without affecting the network configuration of the devices. Passive configuration mode
enables a plug-in to be used on devices installed by network tools not based on LNS.
PCC-10
A type II PC (formerly PCMCIA) card network services interface (NSI) that includes an integral
FTT-10 transceiver. Other transceiver types can be connected to the PCC-10 via external transceiver
"pods". The PCC-10 is the best NSI to use with laptop, notebook, or embedded PCs.
PCLTA-10/20
A ½ size ISA card network services interface (NSI). Unlike the PCNSI, it includes a twisted pair
transceiver onboard, eliminating the need to attach a separate SMX transceiver assembly. The PCLTA-
10 also supports the Windows plug-and-play standard. The PCLTA-10/20 is the best NSI to use on a
host computer attached to a twisted-pair channel.
PCNSI
A half-length ISA card network services interface (NSI). Requires an SMX transceiver to interface to
any L
ON W ORKS communications channel. The PCNSI has two modes of operation – NSI mode and
network interface mode. In NSI mode, the host treats the PCNSI card as a smart peripheral device that
provides access to an NSS either locally on the PC or remotely via the L
ON W ORKS network. In
network interface mode, the host uses the PCNSI card as a standard L ON W ORKS network interface.
Peer-To-Peer
A control strategy in which independent intelligent devices share information directly with each other
and make their own control decisions without the need or delay of using an intermediate, central, or
master controller. Because of the enhanced system reliability introduced by eliminating the master (a
single point of failure) and the reduced installation and configuration cost inherent in peer-to-peer
designs, L
ON W ORKS technology is intended to implement a peer-to-peer control strategy.
Physical Medium
A communication environment that carries the modulated signals from sources to destinations in a
network. L
ON W ORKS supports many media types, including twisted pair, power line, fiber optic cable,
radio frequencies, infrared, and coax.
Plug-in
An easy-to-use ActiveX automation server (*.EXE) that is compatible with LNS and implements the
LNS Plug-in API. It is an application that can be launched by an LNS director application and adds
functionality to that application. Typically, LNS plug-ins add device-specific functionality to an LNS
tool, but they can also add system level functionality. Device-specific plug-ins are usually graphical
software tools for configuring an application program in a L
ON W ORKS device.
