Usage

STEP Part 21 data exchange files

Scope

ISO 10303-221 is an application protocol for "Functional Data and Schematic Representation for Process Plant", dealing with the 2-D world of process design involving piping and instrumentation diagrams (P&IDs) and datasheets.

Considers the representation and exchange of process-plant functional data and its 2D schematic representation. The core of the functional data is the identification and description of the equipment and components within the plant (i.e. identification of systems and equipment)

Characteristics

See Interoperability Tutorial for details on terms used below.

Domain

Industrial Process Facilities

Standard Type

Traditional

Standards Process

Standardize then Implement.

Intellectual Property (IP)

Royalty-free usage of international standard purchased from ISO.

Cost of one interface

Unknown

File Format

STEP Part 21 files

Focus

Comprehensive approach to data exchange and sharing.

Scope

Very generic data model to support multiple domains with the same generic terminology

Scalability

Intended to be used with exchanging information between large data warehouses.

Extensibility

Dynamically extensible between two agreeable parties.

Model Content

Broad on classifications of things, shallow in depth of detail (properties).

Usage

Primary usage is exchange of data in large data warehouses.

Exchange Content

Exchange files contain first the data model and then the data.

Data model approach

Data model uses abstract domain approach which requires application mapping to abstract terminology.

Benefits

Increases the cost efficiency of process plant facilities.

• Significant cost savings are expected from standardization of component specifications
• Design can be progressed in parallel with other engineering, planning, and logistical activities
• Improved efficiency and effectiveness of the operational phase of the plant
• Allows for statistical analysis resulting in discovery of knowledge
