IEC 61784-5-19:2024

Overview - IEC 61784-5-19:2024 (CPF 19 | MECHATROLINK)

IEC 61784-5-19:2024 specifies installation profiles for CPF 19, covering fieldbus installation requirements for MECHATROLINK™ technologies (CPF 19). The standard organizes detailed guidance in normative annexes and is to be read in conjunction with IEC 61918:2018 and its amendments (AMD1:2022, AMD2:2024). It focuses on practical, on‑site topics such as cabling selection, connector and terminator installation, earthing, verification and acceptance testing, and ongoing maintenance.

Note: MECHATROLINK™ and Σ‑LINK™ II are trade names of YASKAWA ELECTRIC CORPORATION; use of the trade name requires permission from the trade name holder. Compliance to this profile does not require use of those trade names.

Key topics and technical requirements

• Installation planning: network topology options (including repeaters), planning requirements and documentation needed for CPF 19 deployments.
• Cabling and components: selection and use of cable types, cable structure considerations, shielded cabling, and recommended cabling practices.
• Connectors and terminators: installation requirements for single‑ and dual‑port device connectors, cable connectors with/without inductors, and correct terminator placement.
• Device installation: mechanical and electrical installation guidance for field devices and ports.
• Earthing and bonding: grounding practices for equipment, devices and cable shields to minimize interference and ensure reliable communications.
• Verification and acceptance testing: procedures for installation verification and installation acceptance tests to validate cabling, connectivity and network capability.
• Documentation and administration: requirements for cabling planning records, “as‑implemented” documentation, coding/labeling and installation administration.
• Maintenance and troubleshooting: recommended maintenance practices and specific troubleshooting steps for CPF 19 networks.

Practical applications - who uses this standard

• System integrators and automation engineers deploying MECHATROLINK fieldbus networks.
• OEMs and machine builders specifying reliable fieldbus installations and acceptance criteria.
• Installation technicians and electrical contractors implementing cabling, connectors and terminators.
• Maintenance teams and technical support staff performing verification, diagnostics and long‑term upkeep.
• Procurement and compliance teams referencing installation profiles for conformance and quality assurance.
