IEC 61784-5-2:2018

Overview

IEC 61784-5-2:2018 (consolidated with Amendment 1, 2024) defines installation profiles for CPF 2 (CIP™) used in industrial communication networks. It specifies how the communication profiles (CP) in CPF 2 - notably ControlNet™ (CP 2/1), EtherNet/IP™ (CP 2/2) and DeviceNet™ (CP 2/3) - shall be installed, tested and maintained by referencing IEC 61918 and by providing annexes that supplement, modify or replace applicable requirements. This edition is a technical revision that includes updates such as referencing ISO/IEC 11801‑3, support material for 1 000 Mb/s 4‑pair Ethernet, and clarifications on dual power supplies.

Key topics and technical requirements

• Installation profiles per CP/CPF: Normative annexes for CP 2/1, CP 2/2 and CP 2/3 cover device- and media-specific installation rules.
• Cabling planning and selection: Guidance on choosing cabling components, drop cables, connectors, shielding and earthing/bonding practices aligned with IEC 61918 conventions.
• Installation implementation: Procedures for cable routing, connector and terminator installation, device mounting, labelling and documentation of “as‑implemented” cabling.
• Verification and acceptance testing: Requirements for installation verification and acceptance tests to validate cabling, connectivity and network capabilities.
• Maintenance and troubleshooting: Recommended administration, maintenance routines and troubleshooting steps specific to each CP.
• Network topologies and extension: Advice on repeaters, star/line/ring topologies, node limits and redundant media configurations.
• Updates and technical changes: Replacement of ISO/IEC 24702 references with ISO/IEC 11801‑3, added tables for 1 000 Mb/s 4‑pair Ethernet, and dual‑power supply clarifications.

Practical applications and users

IEC 61784-5-2 is aimed at professionals deploying and maintaining industrial communication networks in factory automation, process control and machine systems. Typical users include:

• Network and automation engineers designing fieldbus and CIP-based systems
• System integrators implementing ControlNet, EtherNet/IP and DeviceNet installations
• Installation contractors and cabling specialists responsible for field wiring, connectorization and shielding
• Maintenance teams and commissioning engineers performing acceptance tests and troubleshooting
• Standards or procurement specialists creating vendor/contract specifications to ensure interoperability and compliance

Related standards and integration

• IEC 61918 (referenced as the baseline for communication profile requirements)
• ISO/IEC 11801‑3 (referenced for structured cabling aspects in this edition)
• Other IEC 61784 parts (for additional CPF families and profile relationships)
