How to Configure the LonWorks Network
The LonWorks option card contains a Neuron chip with a unique address. This Neuron ID is a 48 bit number that
identifies each Neuron chip manufactured.
Addressing nodes on the LonWorks network is performed at the time of installation using an installation tool
or network management tool (e.g., LonMaker). Addressing requires the retrieval of the Neuron ID for the node.
There are several methods by which the network software can retrieve the Neuron ID and address the node:
1.
Service Pin – The push-button service switch sends the Neuron ID over the network.
If the network software prompts the action, press the Service Pin switch (O400) to transmit the Neuron ID
over the network. Please refer to the How to Install section for the location of the Service Pin switch.
2.
Query and Wink
- Upon receiving a wink command, both LEDs flash (½ Hz for 20 sec.) so the installer can
locate the node. The option sends out its Neuron ID over the network in response to the query command.
3.
Neuron ID Label
– The installer can manually enter the Neuron ID during installation. The Neuron ID can
be found on the label of the option in text and barcode.
Resource Files
A LonMark interface file (.XIF file extension) provides the host processor with device information. Using this file
it is possible to design a LonWorks network without the adjustable frequency drive being physically present.
Other resource files are:
•
Type file (.typ file extension)
•
Format file (.fmt file extension)
•
Language description file (.eng, .enu and other file extensions)
The resource files can be downloaded from the web site www.trane.com/vfd.
Here you will also find a free download of an LNS plug-in for the use in the LonMaker tool.
Functional Profiles
LonMark functional profiles are used to describe in detail the application layer interface, including the network
variables, configuration properties, and commonly used control functions.
