5. Configuration of the system5.1. Configuring the System5.1.1. How to Configure the LonWorks NetworkThe LonWorks option card contains a Neuron chip with a unique address. This Neuron ID is a 48bit number that identifies each Neuron chip manufactured.Addressing nodes on the LonWorks network is performed at the time of installation using an in-stallation tool or network management tool (e.g. LonMaker). Addressing requires the retrieval ofthe Neuron ID for the node.There are several methods by which the network software can retrieve the Neuron ID and addressthe 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 theNeuron ID over the network. Please refer to the How to Install section for the location of theService Pin switch.2. Query and Wink - Upon receiving a Wink command, both LED’s flashes (½ Hz for 20 sec.)so the installer can locate the node. The option sends out its Neuron ID over the network inresponse to the query command.3. Neuron ID Label – The installer can manually enter the Neuron ID during installation. TheNeuron ID can be found on the label of the option in text and barcode.Resource FilesA 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 con-verter 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 sitewww.danfoss.com/BusinessAreas/Driv-esSolution.Here you will also find a free download of an LNS plug-in for the use in the LonMaker tool.5.1.2.
