Overview
IEC 62591:2016, titled Industrial networks - Wireless communication network and communication profiles - WirelessHART™, is an international standard developed by the International Electrotechnical Commission (IEC). This standard specifies a comprehensive wireless communication network designed for industrial automation and process control environments. It complements Type 20 elements in IEC 61158 and the Communication Profile CP 9/2 in IEC 61784-1, focusing specifically on WirelessHART™, a secure and reliable wireless sensor networking protocol widely used in industrial applications.
The 2016 edition is a technical revision of the original 2010 publication. It introduces significant enhancements such as advanced performance statistics including key performance indicators (KPIs), "stale data" detection mechanisms, extended CCA modes aligned with IEEE 802.15.4 standards, added gateway commands, and more precise definitions related to network joining and device management. Additionally, the corrigendum from March 2021 has been incorporated in this edition.
Key Topics
IEC 62591:2016 covers essential layers and functions critical to the wireless communication network, structured as follows:
- Physical Layer: Defines service specifications and protocol for wireless communication, ensuring robust and reliable signal transmission.
- Data-Link Layer: Details services and protocol for message handling, media access control, scheduling, and network topology management tailored for wireless industrial environments.
- Network and Transport Layers: Outline protocols for routing, network management, and data transport with considerations for security and performance.
- Application Layer: Specifies data types, communication models, and protocol services to facilitate efficient and standardized data exchange in industrial networks.
- Network Management: Provides procedures for device onboarding, configuration, fault detection, and maintenance.
- Security: Specifies encryption, authentication, and key management techniques ensuring secure wireless communication in sensitive industrial settings.
- Communication Profile: Defines WirelessHART-specific profiles and operational procedures, including gateway interfacing and network optimization.
- Wireless Procedures and Gateway: Enhancements to network performance monitoring, stale data detection, quarantine states, whitelist and blacklist management, and gateway command support.
These detailed specifications cover everything from logical link control and medium access control to QoS (Quality of Service) parameters, error detection, and state machine behaviors vital for seamless industrial wireless communication.
Applications
IEC 62591:2016 serves as a crucial reference for industries deploying wireless instrumentation and control systems, particularly those seeking to leverage WirelessHART™ technology. Key application areas include:
