type of medium. The LonManager Protocol Analyzer includes three tools for network analysis and
monitoring:
• Packet monitor tool
• Network traffic statistics tool
• Network diagnostics tool
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 Association.
LonTalk File Transfer Protocol
An interoperable way for devices to share data files. The file types— 0, 1, and 2—are defined by the
LonMark program for specifying configuration parameters.
LonTalk Protocol
Echelon’s implementation of the ANSI/ CEA-709.1 (EN14908) standard. The LonTalk protocol
provides a standard method for devices on a LonWorks network to exchange data. The 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.
LonWorks-IP Configuration Server (Config Server)
The LonWorks-IP Configuration Server maintains an IP routing table database required for IP-852
channels. It is used for networks using an IP-852 channel. Only one Config Server is required or
allowed per LNS server or IP network.
L ON W ORKS Technology
The technology that allows for the creation of open, interoperable control networks that communicate
with the LonTalk protocol. L
ON W ORKS technology consists of the tools and components required to
build intelligent device and to install them in control networks.
Message Tag
Logical input and output ports that devices use to send and receive explicit messages. Message tags are
used for standard data transfer mechanisms such as the L
ON W ORKS file transfer protocol and the
L ON W ORKS data log transfer protocol. In addition, they are used as a proprietary interface to devices
such as factory calibration interfaces. Message tags can only be added to the virtual functional block
of a device that supports message tags. A device always contains a msg_in tag and may contain
declared message tags as well. Declared message tags are bi-directional (the device can both send and
receive messages with them). The msg_in tag can only be used to receive messages. Generally,
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 the LonMaker tool uses to monitor and control network variables.
Monitored Connection
A connector shape 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 LonTalk protocol in
each device of the network. This includes:
• Assigning domain ID and logical addresses to all devices and groups of devices.
