Assigning nvs using a Lon Xml file

The Lon Xml file (extension .lnml) for each device specifies its Program Id and the types of messages and variables (nvs = network variables) it is capable of sending and receiving. This procedure associates a Lon Xml file with a dynamic device that is already in the station database.

Prerequisites: The dynamic device exists in the station database. The Lon Xml file exists.

Right-click the dynamic device node in the Nav tree, and do one of the following:
- Click the ImportXml command, click the folder icon to the right of the Xml File property, and select File Ord Chooser from the drop-down list.
- Click Views > Property Sheet, click the folder icon to the right of the Xml File property, and click the File Ord Chooser from the drop-down list.
The File Chooser opens.
Click My Modules in the File Spaces pane, scroll down to the files that begin with “lon,” and double-click the Lon module for your device.
The list of available modules opens in the center pane. This list includes Lon Xml file previously made using the Lon Xml Tool.
Double-click the module file.
The File Chooser opens a list of the available .lnml files for the selected device. For example, lonSiebe includes these .lnml files: Mnlrh2.lnml, Mnlrh3.lnml, and so on. Each file name corresponds to the known xif file name for a device.
Use the device manufacturer’s documentation to determine which file to choose.
Click an .lnml file, then click Open.

The File Chooser closes, and the Import Xml window shows the selected .lnml file.
To import the .lnml file into the dynamic device component, click OK.

The property sheet lists the Network Variable inputs and outputs (nvis and nvos) that are associated with the device.

Now that the available data items are known, you can use the Lon Point Manager under that device to add (offline) proxy points.
