LonMaker User’s Guide 391
Priority
A LonTalk protocol service for messages sent from L ON W ORKS devices that allow a message priority
access to a channel. Priority traffic is delivered before other traffic. Priority is a resource of the
channel.
Protocol Analyzer
A tool that can read every packet on a L ON W ORKS channel. A protocol analyzer is different from a
device containing the complete LonTalk protocol stack in that it can receive every packet on the
network, not just packets that are addressed to it. Protocol analyzers allow users to observe, analyze,
and diagnose the behavior of installed L
ON W ORKS networks. Both the LonBuilder Protocol Analyzer
and the LonManager Protocol Analyzer include the following tools for network analysis and diagnosis:
• Packet monitor tool
• Network traffic statistics tool
• Network diagnostics tool
Recommissioning
Process in which the LonMaker tool downloads network and application configuration data into a
physical device without a Neuron ID being specified (the Neuron ID has already been stored in the
network database).
Reference Connection
A connection represented by a pair of identically named shapes attached to both ends of the
connection. Reference connection shapes can be used to simplify a LonMaker drawing and connect
functional blocks and supernodes in different subsystems.
Remote Full Client
A LonMaker computer that communicates with the LNS Server (running on a separate computer) over
a LonWorks channel (an IP-852 or TP/XF-1250 channel). On a remote full client, network
management tasks are routed through the LNS Server, but monitoring and controlling tasks are sent
directly to the network without going through the LNS Server.
Remote Lightweight Client
A LonMaker computer that communicates with the LNS Server (running on a separate computer)
using an LNS/IP interface. On a remote lightweight client, network management, monitoring, and
controlling tasks are all routed through the LNS Server.
Repeated Service
A service of the LonTalk protocol with which a message is sent more than once to help ensures
message delivery to the addressee(s). The message is sent with a configurable number of retries. There
is no acknowledgement from the addressee(s) that the message has been delivered.
Reset
Management command that stops a device application, terminates all incoming and outgoing
messages, sets all temporary settings to their initial values, and then restarts the device application. If a
device was offline, it is placed online.
Resource File
A file included with a L ON W ORKS device that defines the components of the device interface to be
used by the LonMaker tool. Defined components include network variable types, configuration
property types, and functional profiles implemented by the device application. Resource files allow for
the correct formatting of the data, and they are necessary for L
ON M ARK certification of a device.
