Echelon IzoT BACnet Developes - Manual (Page 26)

OpenLNS Server Computer
A computer running the OpenLNS Server software. The OpenLNS Server computer contains the
OpenLNS global database, which includes the group of L
ON W ORKS networks being managed by the
OpenLNS Server, plus a network database for each network managed by the server.
Out-Of-Service
A BACnet Object can be marked Out-Of-Service, which then allows writes to the Present Value to
take place. However, this value is not allowed to be transferred to the hardware output itself. This is
used for testing.
Local Client
An OpenLNS application running on the same computer as the OpenLNS Server.
Local Device
An Echelon Series 6000 EVB board running the NcMultiSensorExample application that receives
SNVT_lux and/or SNVT_temp_p output network variable updates from another device (a remote
device). The local device displays the temperature and light level values received from the remote
device in the Remote Info Mode panel on its LCD. A remote device may be another Echelon Series
6000 EVB board running the NcMultiSensorExample application.
OpenLNS Commissioning Tool (OpenLNS CT) Browser
An OpenLNS plug-in that provides a table view of the network variables and configuration properties
of selected devices and/or functional blocks. The OpenLNS Brower can be used to monitor and
control the network variables and configuration properties in a network.
OpenLNS CT Drawing
An OpenLNS drawing contains the graphical representation of a L ON W ORKS network.
OpenLNS Commissioning Tool
An OpenLNS network tool that uses Visio as its graphical user interface. The 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.
LonMark
A distinctive logo applied to L ON W ORKS devices that have been certified to the interoperability
standards of the L ON M ARK Interoperability International.
LonTalk Protocol
Echelon’s implementation of the ISO/IEC 14908-1 Control Network Protocol (CNP). The LonTalk
protocol provides a standard method for devices on a L
ON W ORKS network to exchange data. The
LonTalk protocol defines the format of the messages being transmitted between devices, and it defines
the actions expected when one device sends a message to another. The protocol normally takes the
form of embedded software or firmware code in each device on the network.
L ON W ORKS Network
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.
L ON W ORKS Technology
The technology that allows for the creation of open, interoperable control networks that communicate
with the ISO/IEC 14908-1 Control Network Protocol. L
ON W ORKS technology consists of the tools
and components required to build intelligent device and to install them in control networks.
