XILON HANDHELD TOOL - USER GUIDE

GLOSSARY

AI: analog input.
ALTOhandheld: The original name of the XILON Handheld (which is based on
SysMik's ALTOhandheld).
AO: analog output.
binding: The process of defining the connections between different NV's;
specifically: the process of defining the data which nodes share with one another.
Binding is performed during the commissioning phase using a L W network
ON ORKS
management node or tool.
database: The XILON database is the repository for all data about the nodes
present in the L W network. Using XILON, the database can be updated and
ON ORKS
the entire database can be cleared.
DI: digital input.
DO: digital output.
domain: A domain is a logical collection of nodes (on one or more channels) that
can communicate with each other over shared resources such as transmission
media. Only nodes configured so as to belong to the same domain can
communicate with each other; a domain thus forms a virtual network. Multiple
domains can occupy the same channels, so domains may be used to prevent
interference between nodes in different networks. Each network must have at least
one domain. A single domain can contain up to 256 groups (q.v.). A domain is
identified by a domain ID (q.v.).
domain ID: A domain is identified by a domain ID consisting of 0,1,3, or 6 bytes.
Six-byte domain IDs can be used to ensure that the domain ID is unique. Larger
domain IDs increase network overhead since the domain ID is sent with every
message packet.
group: A group is a logical collection of nodes within a domain. A group can
contain up to 64 nodes.
menu, toolbar: The menu on the XILON Handheld Tool for Wiring Checks when
displayed in the form of icons. Menu entries can be selected either using cursor
keys, or by pressing <F1>..<F9> or <SHIFT><F1>..<SHIFT><F9>. The upper row
of eight menuscan be selected from anywhere in the operation sequence. By
pressing <ESC>, you can switch from the toolbar menu to the tree menu and vice-
versa.
menu, tree view: The menu on the XILON Handheld Tool for Wiring Checks when
displayed with a tree structure. <ENTER> is used to expand and <ESC> to
collapse a sub-tree.
MIP (Microprocessor Interface Program): An application running on the Neuron
Chip and used to build customized network interfaces.
network variable (NV): High-level data objects that L W application nodes
ON ORKS
use to communicate with one another. The types, functions, and number of network
variables are determined by the application code within the node.
node: Any device present in the L W network (e.g. controllers, Distributed
ON ORKS
I/O modules, Excel Smart I/O modules, third-party devices, etc.) including XILON
itself.
node, gateway: A node serving as an access between two or more subsystems in
a control system.
parameter: The I/O function used in conjunction with Compact ACU controllers
shows, inter alia, the configuration parameters.
receive timer: More properly referred to as the "group receive timer". One of the
numerous LonTalk protocol timers referred to collectively as the "Layer 4 Timers"
which are typically configured automatically by a network management tool.
LonBuilder and NetMaker automatically calculate and configure these timers.
