360 Appendix B – Glossary
OpenLNS Commissioning Tool (CT)
An OpenLNS network tool that uses Visio as its graphical user interface. OpenLNS CT is used to
design, commission, maintain, and document distributed control networks comprised of both
L
ON M ARK and other L ON W ORKS devices.
OpenLNS CT Layers
Separate views for the physical, logical, and data components in an OpenLNS CT network that can be
used to hide and show parts of an OpenLNS CT drawing. The physical layer includes devices, routers,
channels; the logical layer contains the functional blocks, network variables, and unmonitored
connections; and the data layer consists of monitored connections. Subsystems and supernodes belong
to both the physical and logical layers.
OpenLNS CT Network Design
An OpenLNS network database and an associated OpenLNS CT drawing.
OpenLNS CT Shape
A reusable drawing object related specifically to a L ON W ORKS device, connection, channel, or
subsystem.
OpenLNS CT Style
A SmartShape style indicating the state of a device, functional block, connection, or network
variable/message tag.
OpenLNS Plug-in
An OpenLNS application that implements the OpenLNS Plug-in API. OpenLNS plug-ins provide a
standard way to extend and customize the functionality of OpenLNS applications and tools such as the
OpenLNS Commissioning Tool. For example, OpenLNS plug-ins allow device manufacturers to
provide customized software that simplifies the configuration, monitoring, or control of their devices
that work seamlessly with the OpenLNS Commissioning Tool and other OpenLNS tools. OpenLNS
plug-ins that are specific to a particular type of device are sometimes referred to as device plug-ins.
OpenLNS plug-ins can also add new functionality to OpenLNS applications such as alarming, logging,
and trending. The OpenLNS Plug-in API is compatible with the LNS Plug-in API, and LNS plug-ins
are typically compatible with OpenLNS tools and application that support plug-ins.
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 containing the network variables. 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 OpenLNS.
PCC-10
A type II PC (formerly PCMCIA) network interface card network that includes an integral TP/FT-10
transceiver. Other transceiver types can be connected to the PCC-10 via external transceiver pods.
PCLTA-10/20
A ½ size ISA network interface card.
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
