Full title and description

St IEC 62424-2016 — Representation of process control engineering — Requests in P&I diagrams and data exchange between P&ID tools and PCE‑CAE tools. This international standard defines how process control engineering (PCE) requests are represented on Piping & Instrumentation Diagrams (P&IDs) and specifies a neutral data‑exchange format (CAEX v3.0) for automatic import/export between P&ID tools and PCE/CAE tools to avoid misinterpretation of graphical symbols and to support interoperable toolchains.

Abstract

IEC 62424:2016 (Edition 2.0) is a technical revision of the 2008 edition that provides updated definitions, a reference‑designation approach, expanded PCE categories and process functions, and an electronic data model including normative and informative attribute libraries. The standard adopts CAEX version 3.0 features (multiple role support, nested interfaces, life‑cycle meta information) to enable robust, standardized exchange of PCE request data between engineering tools.

Scope

IEC 62424:2016 specifies the graphical and data representation rules for process control engineering requests on P&ID drawings and the corresponding electronic data model and libraries required to transfer those requests automatically between P&ID tools and PCE‑CAE tools. It applies to export/import functions of such tools and defines the use of the CAEX data transfer language (CAEX v3.0) for that purpose. The edition cancels and replaces the 2008 edition and constitutes a compatible technical extension.

Key topics and requirements

• Representation rules for PCE requests on P&ID diagrams (reference designation, category and function semantics).
• Definition of an electronic data model for PCE requests, including a normative attribute library for basic attributes and an informative extended attribute library.
• Use of CAEX (Computer Aided Engineering Exchange) version 3.0 as the neutral exchange format — supporting native multiple role assignments, nested interfaces and lifecycle meta information.
• Requirements to ensure semantic integrity during automated import/export of P&ID ↔ PCE tool data.
• Updated examples and guidance for tool implementers to map graphical P&ID elements to PCE data structures.

Typical use and users

Primary users include process control engineers, instrumentation and control designers, plant engineering teams, P&ID and CAE tool vendors, systems integrators and automation software developers. The standard is used when exchanging P&ID information with process control engineering applications to reduce manual re‑entry, eliminate ambiguity in symbol interpretation, and support consistent attribute transfer across toolchains. European and national standards bodies have adopted the IEC text as EN/BS/UNE editions for use in procurement and tool conformity activities.

Related standards

Relevant and related standards include: IEC 62424:2008 (previous edition, withdrawn/replaced by the 2016 edition); EN 62424:2016 / national adoptions; standards in the AutomationML/AML family such as IEC 62714‑1 (Automation Markup Language) which references CAEX 3.0 concepts and interoperable engineering data exchange; and other TC65 publications addressing device and tool integration. These documents are commonly considered together when implementing tool interoperability in industrial automation projects.

FAQ

Q: What is this standard?

A: IEC 62424:2016 is an international standard that specifies how process control engineering requests are shown on P&ID diagrams and how the relevant request data shall be exchanged electronically between P&ID tools and PCE‑CAE tools, using CAEX as the exchange language.

Q: What does it cover?

A: It covers representation rules for PCE requests on diagrams, a normative and informative set of attribute libraries, an electronic data model for PCE requests, and rules for exporting/importing that data between engineering tools (CAEX v3.0). The 2016 edition expands definitions, updates PCE categories and adds CAEX 3.0 features (multiple roles, nested interfaces, lifecycle meta information).

Q: Who typically uses it?

A: Process control designers, P&ID and CAE tool vendors, automation engineers, systems integrators and plant engineering teams use the standard to enable automated, semantically correct transfer of P&ID information into control‑system engineering tools. National standard bodies and industry tool suppliers also reference it for conformity and product documentation.

Q: Is it current or superseded?

A: IEC 62424:2016 (Edition 2.0) cancels and replaces IEC 62424:2008; the 2016 edition is the current technical edition as published by IEC (stability information published with the IEC record). Users should verify national adoption status and check for any later revisions after the 2016 edition.

Q: Is it part of a series?

A: While IEC 62424 is a standalone standard for PCE request representation and CAEX‑based exchange, it is closely related to the AutomationML / AML family (IEC 62714 series) and other TC65 publications that together form an ecosystem for engineering data exchange in industrial automation. CAEX concepts from IEC 62424 are used by AML standards for broader tool interoperability.

Q: What are the key keywords?

A: Key keywords include P&ID, PCE, CAEX, CAEX 3.0, AutomationML, attribute library, reference designation, data exchange, interoperability, PCE‑CAE.
