About point actions
Writable points have actions, which, by default appear in a right-click menu when you select a point in a Workbench view or in the Nav tree.
An action is a slot that activates a behavior. Other control objects and extensions also have actions.
In the case of the four writable control points, default actions include the ability to:
Often, you modify a writable point’s value using actions.
Override actions
The actions that override a point’s value include Emergency Active, Emergency Inactive, Emergency Active, and Inactive.
You override a point’s value at priority levels In1 (emergency override) and In8 (override). This is where control can be independently set or automatically initiated at either level. A level In8 override may last for a defined (or custom) length of time, as specified in the action’s window.
Whenever a writable point is controlled from an action issued at either override level, it has an override status. By default, override status color is violet. A manual (level 8) override action to a point (not auto) prompts for an override duration
By default, a Permanent override is the first choice in the drop-down
list—the override value will remain effective until the next
time this action is auto’ed. Other timed durations are available,
including a Custom selection in which a user specifies
a duration in hours, minutes, and seconds.
If needed, you can limit the maximum duration of manual override using facets.
After clicking OK, the override action is issued to the point—if this is the highest effective priority level, the writable point operates under this control. If this is a timed override, the action is automatically auto’ed upon expiration of the override period.
The Set action
Set the value of the point’s Fallback property.
