Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1271: Application module: State characterized (ISO/TS 10303-1271:2004). This technical specification defines the STEP application module used to represent state definitions and observed states, and to assign properties and management/resource information to states within product and process data exchange models.

Abstract

ISO/TS 10303-1271:2004 specifies an application module (a reusable STEP module) called "State characterized". It defines the data constructs and definitions necessary to: assign management and resource information to a state definition and to a specific observed state; associate properties with identified states or individual state instances; and assign properties to state definitions or state types. The module is intended as a building block for STEP application protocols and other exchange schemas that need to represent state information about products, components or processes.

General information

• Status: Withdrawn (original edition withdrawn and subsequently revised by later editions).
• Publication date: December 2004 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.040.40 (Industrial process measurement and control).
• Edition / version: Edition 1 (2004). This module was later revised in subsequent editions (notably 2010/2011 and republished in 2022).
• Number of pages: 31 pages (2004 edition).

Scope

This technical specification covers the EXPRESS-based definition of an application module that models "state" information for product and process data exchange. In scope are: the definitions required to record and manage resource/management information associated with a state definition and with states observed in the real world; mechanisms to assign properties to state instances and to state definitions or types; and the modular constructs intended for inclusion in higher-level STEP application protocols or profiles that require state characterization.

Key topics and requirements

• Definition of data constructs for state definitions and observed state instances.
• Assignment of management and resource metadata to state definitions and observed states.
• Mechanisms for assigning properties to identified states and to state types/definitions.
• EXPRESS schema elements (application module) designed for reuse within ISO 10303 STEP APs and application modules.
• Interoperability considerations for exchanging state information across CAD, PDM, PLM and process-control systems.

Typical use and users

Implementers of STEP (ISO 10303) application protocols, developers of CAD/PDM/PLM software, system integrators working on product lifecycle and process-control data exchange, and organizations needing to represent, record or exchange the state of products, components or processes. Typical scenarios include asset/state tracking, maintenance records, process monitoring, change-state reporting, and integration between engineering and operational systems.

Related standards

This module is part of the ISO 10303 (STEP) family. Closely related documents include other STEP application modules in the 1260–1280 range (for example ISO/TS 10303-1270, ISO/TS 10303-1278) and the integrated resources and application protocol parts of ISO 10303 (parts in the 40–62 and 201–299 ranges). Later revisions of this module were published in subsequent editions of ISO/TS 10303-1271 (published in later years and incorporated into the STEP Module and Resource Library used by APs).

FAQ

Q: What is this standard?

A: ISO/TS 10303-1271:2004 is a STEP application module titled "State characterized" that defines data constructs for representing states (definitions and observations) and assigning properties and management information to those states in product/process data exchanges.

Q: What does it cover?

A: It covers EXPRESS-schema definitions and rules for: creating state definitions, recording observed states, assigning properties to states or state types, and attaching management/resource metadata to states for use within STEP-based data exchange solutions.

Q: Who typically uses it?

A: CAD/PDM/PLM software vendors, systems integrators, data modelers, and organizations that exchange lifecycle, maintenance or status information about products and processes using STEP-based formats.

Q: Is it current or superseded?

A: The 2004 edition is withdrawn and has been superseded by later revisions of ISO/TS 10303-1271 published in subsequent years (later editions were published in the 2010/2011 timeframe and a further, current edition was published in December 2022). Users should adopt the most recent published edition (check the current ISO catalog for the latest edition and status).

Q: Is it part of a series?

A: Yes. It is one application module within the ISO 10303 (STEP) family of standards. Application modules in the 1260–1280 range and the broader ISO 10303 parts (integrated resources and application protocols) are intended to be combined to build complete data exchange schemas.

Q: What are the key keywords?

A: State, state characterized, state definition, observed state, property assignment, application module, STEP, ISO 10303, EXPRESS, product data exchange.
