EN 62026-3:2015/A11:2020

Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 3: DeviceNet

IEC 62026-3:2014 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two conductor pairs within one cable - one of these pairs provides a differential communication medium and the other pair provides power to the devices. This part establishes requirements for the interoperability of components with such interfaces. This third edition of IEC 62026-3 cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. The main changes with respect to the previous edition are the followings: - specification of group 4 messages (5.1.2); - clarifications on messaging protocol (5.2); - addition of I/O multicast poll messages (5.5.2 and 5.5.8); - clarifications on slave behaviour (5.5.4 and 5.5.9); - clarifications on physical layer (transceiver) in 5.7; - miscellaneous corrections/clarifications on cable (8.2); - clarifications on EMC testing (9.2.10) and logical testing (9.3).

Overview

EN 62026-3:2015/A11:2020 is a crucial European standard developed by CLC (European Committee for Electrotechnical Standardization) that addresses the interface requirements between low-voltage switchgear and controlgear devices and their controllers. Specifically, this amendment updates Part 3 of the IEC 62026 series, focusing on DeviceNet controller-device interfaces (CDIs). It ensures reliable interoperability, communication, and power supply via a two-pair cable system-one pair for differential communication and the other for powering devices.

This document replaces the previous 2008 edition by introducing technical enhancements such as refined messaging protocols, added multicast polling, and clarified behavior of slave devices. The amendment supports manufacturers and integrators in designing compliant equipment that meets modern interoperability and EMC (electromagnetic compatibility) requirements.

Key Topics

• Controller-Device Interface (CDI) System
  Defines a communication and power interface system using two conductor pairs, essential for single or multiple controllers to interact effectively with control circuit devices.

• DeviceNet Protocol Enhancements
  Updates include group 4 message specifications, improvements in messaging protocols, and addition of I/O multicast poll messages, enabling better network management and communication efficiency.

• Slave Device Behavior Clarifications
  Detailed guidance on how slave devices should behave to ensure expected communication cycles and system reliability.

• Physical Layer (Transceiver) Specifications
  Clarifies hardware requirements needed for underlying communication signals, ensuring data integrity and robustness in device networking.

• Cable and EMC Testing Improvements
  Incorporates corrections and clarifications on cable specifications and electromagnetic compatibility tests to guarantee compliance with EU Directive 2014/30/EU.

• Interoperability Requirements
  Standardizes component interactions within the CDI network, fostering consistency across various manufacturers and reducing integration issues.

Applications

• Industrial Automation Systems
  Enables seamless connectivity between controllers and devices such as sensors, actuators, and switches in factory automation and process control.

• Building Management Systems
  Supports reliable control and communication in HVAC, lighting, and security systems relying on low-voltage equipment.

• Machinery Control Panels
  Assists in designing control panels where multiple devices communicate via DeviceNet interfaces, ensuring compliance with safety and EMC regulations.

• Energy Management and Distribution
  Facilitates implementation of networked control devices for monitoring and managing low-voltage electrical distribution.

• OEM and Equipment Manufacturer Design
  Provides a standardized interface guideline for embedded device design, reducing time-to-market and enhancing product compatibility.

Related Standards

• IEC 62026 Series
  The broader series governing controller-device interfaces in various industrial environments.

• EN 55011
  Pertains to electromagnetic noise, referenced within EMC compliance clauses for emissions testing.

• Directive 2014/30/EU (EMC Directive)
  Harmonizes electromagnetic compatibility requirements across the EU, supported by conformity to EN 62026-3.

• ISO/IEC/IEEE 11179
  Although not directly referenced, it often complements device-level standards by managing metadata registries critical in industrial device communications.

• EN 61131
  Relevant for programmable controllers interfacing through DeviceNet networks, thus related for integrated control solutions.

---

By adopting EN 62026-3:2015/A11:2020, manufacturers and system integrators ensure robust, standardized communication interfaces for low-voltage switchgear and controlgear. This supports improved system interoperability, greater reliability, and compliance with European regulatory requirements-essential for modern industrial and commercial electrical control applications.
