IEC 61784-5-12:2024

Overview

IEC 61784-5-12:2024 defines the installation profile for CPF 12 (EtherCAT™) within the IEC 61784-5 series for industrial communication networks. Published as Edition 3.0 (March 2024), this standard specifies how to apply the general installation requirements of IEC 61918:2018 (including AMD1:2022 and AMD2:2024) specifically for EtherCAT-based fieldbus installations. The detailed CPF 12 profile is provided as Annex A (normative) and is intended to be read together with IEC 61918.

Note: EtherCAT™ is a Beckhoff trade name; IEC provides this information for convenience and does not endorse the trademark holder. Compliance with the profile does not require use of the trade name.

Key topics and technical requirements

The standard focuses on practical installation and verification requirements for CPF 12 networks. Primary technical topics covered in Annex A include:

• Installation planning

  • Planning requirements and network capability considerations
  • Selection and use of cabling components (balanced copper and optical fibre)
  • Documentation and verification of cabling plans

• Installation implementation

  • Cable, connector and terminator installation practices
  • Device installation, coding and labelling
  • Earthing, bonding and shield cabling requirements

• Verification and acceptance testing

  • Installation verification procedures
  • Installation acceptance test criteria and documentation

• Administration, maintenance and troubleshooting

  • As‑implemented documentation
  • Maintenance and fault‑finding guidance

Supporting material in the annex includes tables for network characteristics (balanced cabling and optical fibre), cable and connector information, and guidance distinguishing fixed, flexible and special cables. Recent technical changes include the addition of four-pair twisted cables and consolidation of references to CPF 12.

Practical applications and users

IEC 61784-5-12 is intended for organizations deploying EtherCAT fieldbus systems in industrial automation and control environments. Typical users include:

• Network planners and system architects - to select cabling, connectors and network topologies consistent with CPF 12
• Installers and commissioning teams - to implement cabling, terminators, earthing and device mounting per the profile
• Verification and validation personnel - to perform installation acceptance tests and document compliance
• Maintenance and administration staff - to maintain as‑implemented records, troubleshoot and manage changes

The standard helps ensure interoperability, predictable performance and reliable installation of EtherCAT-based industrial networks.
