Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1679: Application module: Functional specification. This technical specification defines an ISO 10303 (STEP) application module for representing functional specifications and related behavioural information for functional elements.

Abstract

Specifies the application module for Functional specification. It covers the representation of information needed to describe the behaviour of a functional element under a set of controlled conditions, including signal specification, component data sheet functional-performance representation, and functional specification constructs used within the STEP (ISO 10303) framework.

General information

• Status: Withdrawn (original 2006 edition withdrawn and later revised).
• Publication date: December 2006 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control).
• Edition / version: Edition 1 (2006). A later revision was published as ISO/TS 10303-1679:2018.
• Number of pages: 40 (2006 edition).

Scope

Defines the EXPRESS-based application module(s) needed to represent functional behaviour information for product components within the STEP family. In scope are signal specifications, functional-performance data as might appear on component data sheets, and formal functional specifications that describe behaviour under controlled conditions. The module is intended to support exchange of functional-specification data between engineering and lifecycle systems.

Key topics and requirements

• Representation of functional behaviour and behavioural constraints for a functional element.
• Signal specification constructs for inputs/outputs and timed/event behaviour.
• Component data‑sheet functional performance representation (parameters, ratings, performance curves).
• Formalisation of functional specifications to enable data exchange across CAD/CAM/PDM/PLM systems (STEP application module).
• Compatibility and integration with other ISO 10303 application modules for functional decomposition and interconnect design.

Typical use and users

Used by systems- and hardware-engineers, CAD/CAM/PLM integrators, component and subsystem suppliers, and organizations implementing STEP-based data exchange for functional requirements and performance data. Typical use cases include exchanging functional specifications between design and verification tools, carrying functional data in component datasheets for downstream systems, and integrating functional behaviour into product data models.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1679 (2006) is a STEP technical specification defining an application module for formal representation of functional specifications and related behavioural information for product components.

Q: What does it cover?

A: It covers the EXPRESS application-module constructs needed to describe behaviour of functional elements under controlled conditions, including signal specifications and functional-performance information commonly found on component data sheets.

Q: Who typically uses it?

A: Systems and hardware engineers, CAD/PLM integrators, component suppliers and anyone exchanging functional requirements or functional-performance data using STEP-based formats.

Q: Is it current or superseded?

A: The 2006 edition is listed as withdrawn and has been superseded by a later revision; the newer published version is ISO/TS 10303-1679:2018 (published November/December 2018). For current work use the 2018 revision.
