Enterprise models

The section provides an introduction to enterprise models. Enterprise models provide

structure to support:

nOrganizing your system.

nStructuring your view of alarms.

nDefining the scope of user views and control rights.

This section also includes guidelines for designing enterprise models, as well as examples that

illustrate 'best practice' design principles.

About enterprise models

An enterprise model provides a means of organizing your system around key entities in your

enterprise, such as plant equipment.

An enterprise model provides:

nA hierarchical structure that makes it easier for users to navigate their way through your

system.

nA simple and intuitive means of implementing scope of responsibility—that is,

systematically managing the access rights of operators (or Stations) to various parts of

your system.

nThe mechanism to enable and disable alarming for selected equipment.

An enterprise model is a framework that includes a set of specialized models, such as the asset

and system models, each of which represents one aspect of your system.

About asset models

An asset model forms the core of an enterprise model: it is a hierarchical representation of

your assets, similar to the one shown in the figure below.

An asset represents a particular physical item, such as a piece of plant equipment, a

production line or a building.

About assignable assets and scope of responsibility

An asset model is not just a logical representation of your physical assets and how they relate

to each other. It also provides a framework for defining scope of responsibility (SOR)—that

is, assigning specific assets to specific operators (or Stations).

An asset that you can assign to an operator (or Station) is called an assignableasset. By

default, all top level assets in your asset model are assignable assets. If appropriate, you can

also define assets at other levels as assignable assets.

When you give an operator (or Station) access to an assignable asset, you also give access to

its child assets (except those which have been defined as assignable assets).

If an asset is changed from non-assignable to assignable, any scope of responsibility that was

previously inherited is cleared. As a result, control of this asset is temporarily lost until the

asset is included in the operator's or Station's scope of responsibility.
