New Point Properties Window

This window configures the point properties.

Figure 26. New point properties

Type	Value	Description
Name	text	Shows the name of the point as reported by the device.
Type	drop-down list	Selects the type of point.
Href	text	Reports the URI of the point on the oBIX server.
Facets	`true` or `false` (defaults to `true`)Please Confirm	Displays point’s value in the station
Device Facets	Read only	Reflects the read-only device facets used in the point’s proxy extension.
Enabled	`true` or `false`	Activates (`true`) and deactivates (`false`) the object (network, device, point, component, table, schedule, descriptor, etc.).
Conversion	drop-down list	Selects the units to use when converting values from the device facets to point facets. `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.
Tuning Policies	additional properties	Configures network rules for evaluating both write requests to writable proxy points as well as the acceptable freshness of read requests.
