Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 212: Application protocol: Electrotechnical design and installation. This ISO STEP Application Protocol (AP212) defines the data concepts, EXPRESS schema and exchange semantics needed to represent electrotechnical product information including wiring, cabling, harnesses, electrical equipment and installation data for design, manufacture and installation contexts.

Abstract

ISO 10303-212:2001 (AP212) specifies an application protocol within the ISO 10303 STEP family to enable computer-interpretable representation and exchange of electrotechnical design and installation data. It provides a functional application activity model, an EXPRESS conceptual schema for electrotechnical artefacts (cables, harnesses, connectors, conductors, routing, terminal blocks, installation relationships), and guidance for interchange using STEP data constructs. The standard supports downstream uses such as manufacturing, installation planning and integration with mechanical (MCAD) and electronic (ECAD) models.

Scope

AP212 defines the information requirements and data structures required to represent electrotechnical design and installation information for product lifecycle tasks. The scope covers representation of electrical components, wiring and cable harnesses, interconnections, connection sequences, terminal blocks, routing and installation context, together with the application activity model and mapping to STEP resources required for interchange between CAx/PLM systems and installation/maintenance applications. The protocol was developed jointly with electrotechnical industry partners and aligns with other STEP APs for multi‑discipline integration.

Key topics and requirements

• Application Activity Model (AAM) specifying electrotechnical functions and data flows.
• EXPRESS conceptual schema for electrotechnical entities (cables, conductors, connectors, harnesses, terminals, harness routing and installation relationships).
• Rules for mapping electrotechnical product data to STEP integrated resources and for exchange using STEP file constructs.
• Support for representing interconnections, pin/terminal assignments, wire lists, harness bundles and installation geometry references.
• Interoperability focus to enable ECAD/MCAD/PLM integration and downstream manufacturing/installation tasks.

Typical use and users

Users include electrical design engineers, ECAD and MCAD software vendors, PLM and PDM integrators, automotive and aerospace engineering organisations, contract manufacturers, system integrators and installation/maintenance planners who need neutral, interoperable exchange of electrotechnical product and installation data across tools and lifecycle stages.

Related standards

Part of the ISO 10303 (STEP) family; commonly used alongside other APs such as AP203, AP214, AP210, AP238 and AP242 and STEP infrastructure parts (for example Part 21 for exchange files). AP212 was developed in coordination with relevant IEC electrotechnical work and industry consortia to ensure compatibility with electrical dictionaries and component catalogues.
