of LonWorks
Option Card
Resource
files A LonMark interface file (.XIF extension)
provides the host processor with device
information. With this, it is possible to design a
LonWorks network without the adjustable
frequency drive being physically present.
The resource files (VLTLON.XIF and
DanfossVSD_03.*) can be downloaded from
the Internet site www.danfoss.com/drives.
Echelon Corporation has also developed a set
of free plug-ins available through their web site
at www.echelon.com/plugin/default.htm. Also
intended for network design, these plug-ins
provide easy access to screens which simplify
the process of manually setting up the drive,
testing, and monitoring operation.
The LonWorks option card contains a N
EURON
chip with a unique address. After hardware
installation, initialize the LonWorks option card.
Addressing nodes on the LonWorks network
is performed at installation time by an
installation tool or network management tool.
Addressing requires the retrieval of a node’s
N
EURON
ID. The N
EURON
ID is a 48 bit number
that identifies every manufactured N
EURON
chip. There are several methods by which the
network software will initialize the drive
automatically. The network can recognize the
drive without action beyond proper
installation. The card is then ready to be
programmed for network operation. The VLT
LonWorks option supports three additional
methods of addressing a node:
1. Ser vice Pin - There are two
momentary-contact service switches that
send the N
EURON
ID over the network. If the
network software prompts the action, press
either service pin (SW1 or SW3) to transmit
the N
EURON
ID over the network. The service
pin locations are shown in the illustration in
Terminator and Service Switch Locations in
this manual.
2. Query and Wink - The LonWorks option
card is shipped with a domain of “0” and
subnet of “1.” Upon receiving the wink
command, the on-board green status LED
flashes so that the installer can locate the
node. The chip sends out its Neuron ID over
the network in response to the query
command.
3. N
EURON
ID Label - The VLT LonWorks
option card has a N
EURON
ID label that
displays the N
EURON
ID as a 12 digit
hexadecimal number. The installer can
manually enter the N
EURON
ID during
installation.
The drive may also be added to the network
upon initialization.
The VLT LonWorks network interface
consists of
SNVTs and SCPT. The SNVTs
support the LonMark Controller Profile along
with VLT configuration, control and moni-
toring capabilities. Any combination of SNVTs
can be used to operate the VLT.
We also support the Functional Profile for
Variable Speed Drives version 1.1 from the
LonMark organisation.This profile defines a
set of Network variables (SNVT) and
configuration properties (SCPT).
