IEC 61784-5-8:2024

Overview

IEC 61784-5-8:2024 - Industrial networks - Profiles - Part 5-8: Installation of fieldbuses - Installation profiles for CPF 8 (CC-Link™) - defines installation profiles for the CPF 8 family (CC-Link, CC‑Link/LT, CC‑Link IE variants). The standard provides normative annexes for specific CPF 8 variants and is intended to be read in conjunction with IEC 61918:2018 and its amendments (AMD1:2022, AMD2:2024). It focuses on practical installation rules, planning, verification and conformance for fieldbus deployments that use CC‑Link technologies.

Key topics and technical requirements

The standard organizes installation guidance into systematic, normative profiles covering:

• Installation planning - scope, planning requirements and documented cabling plans.
• Network capabilities - topology, performance constraints and device/network capability descriptions.
• Selection and use of cabling components - guidance on choosing appropriate cabling, connectors and shielding practices for CPF 8.
• Installation implementation - cable routing/installation, connector and terminator installation, device mounting and labelling.
• Earthing and bonding - requirements for equipment earthing, shield termination and grounding practices.
• Verification and acceptance testing - procedures for installation verification, acceptance tests and criteria to confirm compliance.
• Installation administration, maintenance and troubleshooting - as‑implemented documentation, maintenance routines and fault isolation guidance.
• Conformance and profile conventions - how to claim compliance to CPF 8 installation profiles and interpret annex requirements.

Annexes are CP 8/1 & CP 8/2 (CC‑Link V1/V2), CP 8/3 (CC‑Link/LT), CP 8/4 (CC‑Link IE Controller Network), CP 8/5 (CC‑Link IE Field Network) and CP 8/6 (CC‑Link IE TSN), each providing tailored installation profiles.

Practical applications

IEC 61784-5-8:2024 is used where reliable, repeatable installation of CC‑Link fieldbuses is required:

• Industrial plant automation deployments using CC‑Link families
• New-build or retrofit factory networks
• Commissioning and site acceptance testing of fieldbus cabling and devices
• Defining installation contracts, specifications and quality criteria for system integrators and installers

Who should use this standard

• Automation engineers and system integrators specifying CC‑Link networks
• Installation contractors and cabling technicians performing fieldbus installation
• OEMs and machine builders designing CC‑Link-enabled equipment
• Test & validation teams responsible for acceptance testing and conformance checks
• Specifiers and asset owners writing procurement and maintenance documentation
