Add (and Edit) points windows

This window adds device points to the station database.

Figure 73. Add points window

You open this window after double-clicking a Lon network node in the Nav tree, double-clicking the points icon under the Exts column in a device Database pane, discovering points, selecting them in the points Discovered pane and either dragging them to the points Database pane or clicking the Add button.

In addition to the standard property (Facets) this window provides these properties.

Property	Value	Description
Name	text	Provides a name for the point. This value does not affect the Lonworks node. You may change it as needed.
Type	for points: drop-down list (defaults to Numeric Writable for new points)	For new points, identifies the type of point: Numeric, Boolean, Enum, etc. Once created this value cannot be edited.
Target	read-only	Reports the Lon component represented by the proxy point, for example: nvoStatus.
Element	read-only	If the point is structured, reports the element in the structure. If the point is unstructured, reports the SNVT.
Conversion	drop-down list (defaults to Default)	Defines how the system converts proxy extension units to parent point units. `Default` automatically converts similar units (such as Fahrenheit to Celsius) within the proxy point. NOTE: In most cases, the standard `Default` conversion is best. `Linear` applies to voltage input, resistive input and voltage output writable points. Works with linear-acting devices. You use the Scale and Offset properties to convert the output value to a unit other than that defined by device facets. `Linear With Unit` is an extension to the existing linear conversion property. This specifies whether the unit conversion should occur on “Device Value” or “Proxy Value”. The new linear with unit convertor, will have a property to indicate whether the unit conversion should take place before or after the scale/offset conversion. `Reverse Polarity` applies only to Boolean input and relay output writable points. Reverses the logic of the hardware binary input or output. `500 Ohm Shunt` applies to voltage input points only. It reads a 4-to-20mA sensor, where the Ui input requires a 500 ohm resistor wired across (shunting) the input terminals. `Tabular Thermistor` applies to only a Thermistor input point and involves a custom resistance-to-temperature value response curve for Type 3 Thermistor temperature sensors. `Thermistor Type 3` applies to an Thermistor Input point, where this selection provides a “built-in” input resistance-to-temperature value response curve for Type 3 Thermistor temperature sensors. `Generic Tabular` applies to non-linear support for devices other than for thermistor temperature sensors with units in temperature. Generic Tabular uses a lookup table method similar to the “Thermistor Tabular” conversion, but without predefined output units.
Link Type	drop-down list	Configures the type of link between nodes and devices. Options are: `Unknown`, `Standard`, `Reliable`, `Critical`, `Authenticated` and `Poll Only`.
