A network is defined as a collection of components with their parameters. There are a number of object types available in Vision:
•Node
Definition of characteristics (attributes)
All objects are specified through forms with multiple tabs. All electrical properties, among others, are specified on these tabs.
Most objects have predefined types available. The electrical properties of these object types are predefined, so the user does not have to specify them each time.
Five tabs are present for all objects. These tabs are Specifics, Note, Presentation (graphic), Selection and Variations.
Specifics
For all components the user may input on or multiple specific characteristics. A specific characteristic consists of a Characteristic and a Value.
Note
A note can be added to almost all objects. This note is shown in a yellow frame near the object. The size of the note is independent of the zoom level.
Presentation
The graphical presentation of an object can be defined in this tab. See also: Presentation Components.
Selection
A component can be present in a number of selections.
Variations
An object that does not exist in the base situation, but only in a variant from a specific date, is a Variant object. This is indicated on the Variations tab by means of a checkmark at Variant object. The object has then become a variant object. If the object is not yet included in a variant, it will no longer be visible in the standard view after the Variant object box has been checked.
The form also indicates the variant in which the object appears and the date on which the object is taken into or out of service. Active variant items are displayed selected.
The form also specifies the scenario in which the object appears and possibly the date on which the change takes place. Active scenario items are displayed selected.
