control-BooleanWritable

This component extends BooleanPoint to include 16 levels of command priority control. The highest priority active command is reflected in the Out property. Commands at the emergency and manual levels (1 and 8) are stored persistently.

This point is available in the Points folder of the control palette and usually resides in a device’s Points folder.

Figure 206. Boolean Writable properties

You can access these properties by double-clicking the component wherever a Boolean point is used. The point’s characteristic green circle icon with a B in the middle identifies Boolean writable points in the Nav tree and Wire Sheet.

Property	Value	Description
Facets	Config Facets window	Define the text to display for the Boolean values: `trueText` is the text to display when output is true `falseText` is the text to display when output is false. For example, the facet trueText could display “ON” and the facet falseText “OFF.” You view Facets on the Slot Sheet and edit them from a component Property Sheet by clicking the >> icon to display the Config Facets window.
Proxy Ext, Out	message	Provides a current binary value, facets (text descriptors) and data status, such as `fault`, `overridden`, `alarm`, and so on. If no status flag is set, status is considered normal and reports `{ok}.` The station itself originates the point’s default `Out` value.
Proxy Ext, In1–16	values	Indicate from where the point’s value originates, including details specific to the parentage of the point’s network and communications (driver). null indicates that the point is an empty placeholder.
Proxy, Fallback	value	Configures a default `Out` value for a point when a priority scan of inputs `In2` – `In7` and `In9` – `In16`returns a null or invalid value, and no emergency action (`In1`) or manual action (`In8`) has occurred.
Override Expiration	read-only	Reports how long a value that has been set manually (using an action) remains valid.
Min Active Time	hours minutes seconds (defaults to 00000h 00m 00s)	Defines a minimum up time. This property works independently of `Min Inactive Time`. You typically use this property to prevent the short-cycling of equipment controlled by the point. The default disables the timer.
Min Inactive Time	hours minutes seconds (defaults to 00000h 00m 00s)	Defines a minimum down time. This property works independently of `Min Active Time`. You typically use this property to prevent the short-cycling of equipment controlled by the point. The default disables the timer.
Set Min Inactive Time On Start	`true` or `false` (default)	Determines if the minimum inactive time applies at station start.

Actions

This component supports the following actions:

Emergency Active: sets an active output at the emergency level.
Emergency Inactive: sets an inactive output at the emergency level.
Emergency Auto: clears any active or inactive output at the emergency level.
Active: sets an active output at the manual level.
Inactive: sets an inactive output at the manual level.
Auto: clears any active or inactive output at the manual level.
Set: opens the Set window with true and false options, which you can use to manually configure the point’s value.
