Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1674: Application module: Functional assignment to part. Specifies an application module to represent the information needed to assign functional model terminals to physical part terminals and to represent terminals on a physical part that are internally shorted.

Abstract

ISO/TS 10303-1674:2006 defines the EXPRESS application module for “functional assignment to part.” It covers the data constructs required to map usage-view (functional) model terminals to piece‑part model terminals and to record terminals on a physical part that are internally shorted, enabling interoperability of functional-to-physical assignment information within the STEP family of standards.

Scope

This Technical Specification provides the EXPRESS application module definitions and data concepts needed to: (1) support mapping of functional-model usage‑view terminals to piece‑part model terminals, and (2) represent terminals on a physical part that are internally shorted. The module is intended to be used within STEP application protocols and derived implementations where functional-to-physical terminal assignment and shorted-terminal representation are required.

Key topics and requirements

• Application module for functional assignment to part (EXPRESS schema elements and logical model).
• Representation of usage-view/functional terminals and their mapping to piece-part terminals.
• Representation of terminals that are internally shorted on a physical part.
• Data requirements for integrating functional models with physical part models in STEP-based exchange.
• Compatibility and reuse within ISO 10303 application protocols and other related application modules.

Typical use and users

Used by CAD/ECAD/PLM tool developers, integration engineers, systems engineers, and data exchange specialists who need to exchange or persist functional-to-physical terminal assignment information. Typical scenarios include electronic and electromechanical product design, assembly definition, connector/interface specification, and automated translation between functional models and part-level representations.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1674:2006 is a STEP Technical Specification defining an EXPRESS application module for functional assignment to part—data definitions that map functional model terminals to physical part terminals and represent internally shorted terminals on parts.

Q: What does it cover?

A: It covers the data structures and semantics required to represent and exchange assignments between functional (usage-view) terminals and piece‑part (physical) terminals, and the representation of terminals that are internally shorted on a physical part, for use within STEP/APs and other STEP-based data exchanges.

Q: Who typically uses it?

A: CAD/ECAD vendors, PLM integrators, systems and electronics engineers, and organizations that need precise mapping between functional models and physical part interfaces during design, verification, and manufacturing data exchange.

Q: Is it current or superseded?

A: The 2006 Technical Specification edition is recorded as withdrawn on the ISO record and was subsequently revised; a later edition (ISO/TS 10303-1674:2010) exists. Users should prefer the latest confirmed edition of the part for current implementations and consult ISO or national bodies for the authoritative current status and text.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10303 family (STEP). It belongs to the 16xx application module series addressing functional and interconnect representation and is intended to be reused or referenced by other STEP application protocols and modules.

Q: What are the key keywords?

A: Functional assignment, terminals, piece‑part, shorted terminals, STEP, ISO 10303, application module, EXPRESS, data exchange, ECAD, PLM.
