lonworks-LocalLonDevice

This component represents the local interface to the Lonworks fieldbus. Component-wise, it is modeled similar to any other Lon device. As a frozen slot under the LonNetwork, it always appears in the network. There is only one Local Lon Device. You cannot delete it or duplicate it.

Figure 15. Local Lon device properties

You access these properties by expanding the LonNetwork, right-clicking the Local Lon Device node in the Nav tree, and clicking Views > AX Property Sheet.

With a station as the network manager, you can leave Local Lon Device properties at their default settings, and do nothing else at this level in the network.

In addition to the common properties (Status, Enabled, Fault Cause, Health and Alarm Source Info), these properties are unique to this component.

Container	Value	Description
Device Data	additional properties	Identifies the Neuron chip and other information about the Local Lon device.
Points (Lon Point Device Extension)	container	Contains the points associated with this device.
Message In	additional properties	Provides a message ID. Represents a single network variable in a Lon device.
External Config	`true` or `false` (default)	Determines where network management takes place. `true` specifies that all Lonworks network management is performed externally, meaning that you do not use `LonNetwork` views like the Lon Device Manager, Lon Link Manager, and so on.
Self Doc	string of text (defaults to: &3.0@;Niagara Server Node) This property requires `External Config` to be set to `true`	Defines a text string for the host node’s self documentation up to 1024 bytes. A single asterisk () omits self documentation. NOTE:* When using self documentation, always retain the leading header portion (&3.0@) along with an additional zero (0), plus other characters.
nviRequest	additional properties	Configure an network variable input request. For property descriptions, refer to lonworks-LocalNv.
nvoStatus	additional properties	Report network variable output status. For property descriptions, refer to lonworks-LocalNv.

Actions

Figure 16. Local Lon device actions menu

To access these actions, right-click the Local Lon Device and click Actions.

Action	Description
Ping	Attempts communication with the device. If successful, the device status reports {ok}. If this fails, the system sets device status to {down}
Upload	Reads transient (nvs) and persistent (ncis and cps) data from the device and writes them to the station database (Lon device). An Upload window selects the type of data.
Download	Writes persistent data (ncis and cps) to the device from values in the station database (Lon device). A Download window selects recursive writes.
Reset	Issues a reset command to the device.
Service Pin	Issues a Lonworks service pin message for the host node. This action is unique to Local Lon Device, and is useful if installing the host using an external Lonworks network management tool (station as a Lon node only).

NOTE: In general, you should not invoke actions on the Local Lon Device, except a Service Pin
