IEC 62657-2:2022

Overview

IEC 62657-2:2022 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on the coexistence management of wireless systems in industrial networks. It defines fundamental assumptions, concepts, parameters, and procedures essential for managing wireless communication coexistence within industrial automation environments. This edition emphasizes practical strategies and guidelines to ensure robust wireless communication availability and performance throughout the lifecycle of industrial wireless networks.

This standard serves as a common framework that addresses the complexity of multiple wireless systems operating simultaneously within an industrial plant, mitigating interference and optimizing performance. It is applicable to all stakeholders responsible for wireless coexistence, including plant designers, operators, maintenance teams, and regulatory bodies.

Key Topics

• Wireless Communication Coexistence: Detailed explanation of coexistence concepts, including manual, automated non-collaborative, and automated collaborative coexistence management mechanisms.

• Lifecycle Management: Guidance spans all wireless coexistence phases-planning, design, installation, implementation, operation, maintenance, administration, and training to ensure ongoing system resilience.

• Coexistence Parameters: Specification of technical parameters critical to wireless system performance, such as adjacent channel selectivity, antenna gain, communication availability, frequency usage, power levels, interference types, network topology, and device density.

• Interference Management: Identification and handling of interference potentials and ancillary conditions affecting wireless network stability within industrial settings.

• Best Practices and Guidelines: Recommendations aimed at optimizing coexistence management strategies to maintain industrial automation communication reliability and security.

• Operational Aspects: Consideration of both static organizational factors (human, tools) and dynamic network self-organization impacting coexistence.

• Regulatory Framework Support: Contribution toward harmonizing wireless coexistence with national and regional regulations, ensuring compliance without exemption from local requirements.

Applications

• Industrial Automation Plants: Ensures seamless coexistence of multiple wireless systems, improving operational efficiency and minimizing communication disruptions.

• Wireless Network Planning and Design: Provides engineers and planners with comprehensive criteria and assessment models for deploying wireless communication technologies in complex industrial environments.

• Maintenance and Administration: Supports maintenance teams in monitoring, adapting, and troubleshooting wireless systems to prevent interference issues.

• Training and Operational Management: Equips personnel with essential knowledge and methodologies for managing coexistence, contributing to enhanced operational reliability and safety.

• Regulatory Compliance Assessment: Assists organizations in aligning wireless system implementations with mandatory regulations and standards to facilitate certification and market access.

Related Standards

• IEC 62657 Series: Covers additional parts addressing other facets of industrial wireless networks and coexistence.

• IEC 61158 / IEC 61784: Standards related to industrial communication networks and protocols, providing complementary guidelines for network implementation.

• Regional Radio Regulations: National and regional regulatory standards that govern frequency use, power limits, and other wireless communication requirements, which IEC 62657-2 references but does not supersede.

• IEEE 802.11 and 802.15 Standards: Technical standards underpinning many wireless communication technologies relevant to industrial networks.
