CIM ADAPTER

The CIM Adapter for the OSIsoft PI System combines the power of the world's leading real-time historian, PI, with the power system modeling capabilities of the IEC 61970 and IEC 61968 Common Information Model (CIM). The CIM Adapter for the OSIsoft PI System will import XML based data model definitions into the PI Analysis Framework (AF) so that access to data within the PI System can be done within the context of the data model eliminating the need for applications to be pre-programmed with tag names. The result is reusable applications that can access data in the context of a central system model and discover the data they need without having to be pre-programmed with knowledge of all the available data.

OVERVIEW

The CIM Adapter for use with the PI System™ combines the power of OSIsoft's world-leading infrastructure for real-time performance management with the application integration and common information exchange model capabilities of the IEC CIM.

The CIM Adapter processes modeling information, such as a network connectivity model, and automatically configures the PI Asset Framework™ (PI AF) for those points that are being historized by the PI Server™. The CIM Adapter organizes the PI Tags within the context of models familiar to the user such as the IEC Common Information Model (CIM) per IEC 61970/61968 or a user-defined data model. The adapter can also be integrated with the Utility Integration Bus (UIB) to synchronize the PI AF models with changes made to the model in external systems.

The CIM Adapter provides a solution for electric utilities that enables them to leverage their existing power system models to better manage the complexity of their smart grid systems while minimizing manual reconfiguration and data handling. 

FEATURES

• Works with customer-defined models, models derived from other applications, or industry standard models such as CIM, IEC61970 (for EMS), IEC61968 (for DMS), IEC 61850, ISA, etc.
• Imports model information and network connectivity information into PI AF using CIM-XML files
• Can auto-create PI tag names based upon the model definitions
• Enables the use of an enterprise semantic model based on your power system model to be used for developing PI applications without tag name dependencies
• Simplifies management of tag naming changes by supporting incremental change process that updates tag names without manual configuration
• The UIB interface supports model synchronization between AF and the power system models in other systems to enable historization of these external model changes within the PI environment

BENEFITS

• View and search for PI Tags within the context of familiar power system models
• Facilitates the development of reusable analysis and display application for PI ProcessBook™ and PI WebParts™
• Ability to provide automatic configuration updates when changes are made to external models
• Supports a common integration framework that eliminates unwieldy point-to-point data transformations and integration links
• Leverages existing Enterprise Application Integration (EAI) and middleware products (such as IBM WebSphere) to provide maximum performance and flexibility for integration with other enterprise applications

HOW IT WORKS

The CIM Adapter consists of the adapter itself and an import tool. The software allows for model creation and maintenance in PI AF automatically enabling standardized or customer defined models to be used.

Model creation and maintenance is performed through the import of eXtensible Markup Language (XML), Resource Description Format (RDF) and Web Ontology Language (OWL) file formats, which have been standardized by the International Electro-technical Committee (IEC). These formats enable the schema/ model definitions and object instance information to be exchanged.

Model synchronization and maintenance can be enabled through the use of the Utility Integration Bus (UIB). Using the UIB with the CIM Adapter allows changes made in an external model to be automatically delivered to PI AF and to other applications as well (e.g. network applications, GIS, EMS, and others). The model repository can contain model information relating to standard models (e.g. CIM, IEC, ISA, etc.), Customer defined models or models residing in other applications such as GIS, EMS, PSS/ODMS, CIMDE and other network modeling applications and tools.

THE RESULT

Users of PI AF, and other PI AF application tools, will have the ability to view the relationship between measurements and equipment based on the model.

The CIM Adapter creates and maintains the various relationships specified by the model definition. As a result, it is now possible for a PI AF application to locate a transformer that is contained within a substation without having to know the PI Tag names in advance.
