Honeywell 2017 8 Enterprise models Enterprise models The section provides an introduction to enterprise models. Enterprise models provide structure to support: n Organizing your system. n Structuring your view of alarms. n Defining 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: n A hierarchical structure that makes it easier for users to navigate their way through your system. n A 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. n The 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. Honeywell 2017 9 Enterprise models A typical asset model Raw Materials * Digestion * Precipitation * Thickeners * Ball Mill Train 1 Thickener 1 Rod Mill Digestor Thickener 2 Flash Vessel 1 Train 1 Flash Vessel 2 Precipitator 1 Train 2 Agitator Cyclone Precipitator 2 Train 2 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. Honeywell 2017 10 Enterprise models By assigning assets to operators, you not only restrict what assets they can control, you also restrict what they see. For example, if an operator calls up the Alarm Summary it will only display alarms related to assets that have been assigned to that operator. The associated asset on system components can also be used to control which system alarms are displayed to operators, based on their SOR. Attention: Scope of responsibility does not apply to point data on custom displays. If you want to limit the visibility and use of point data on custom displays, you should
