Overview
EN IEC 61784-2-6:2023 is a European standard that defines additional real-time fieldbus profiles for industrial networks, specifically focusing on Communication Profile Family 6 (CPF 6). Part of the IEC 61784 series, this standard extends real-time Ethernet (RTE) communication capabilities based on ISO/IEC/IEEE 8802-3, widely known as Ethernet, and the IEC 61158 series (Types 8 and 10). CPF 6 largely relates to INTERBUS® technologies and their integration with Ethernet-based fieldbus systems. The main objective of EN IEC 61784-2-6:2023 is to ensure predictable, reliable, and synchronized real-time communication in automation and process control environments.
Key Topics
- Communication Profile Family 6 (CPF 6): Defines a set of real-time Ethernet communication profiles and related network components, ensuring standardized data exchange and interoperability between automation devices.
- INTERBUS and PROFINET Integration: Supports the mapping and connectivity between INTERBUS architectures and Ethernet (ISO/IEC/IEEE 8802-3) networks.
- Real-Time Communication: Provides mechanisms for precise, synchronized actions and high-speed data exchange between controllers and field devices.
- Profile Specifications: Outlines profiles 6/4, 6/5, and 6/6, detailing service and protocol selections for linking devices that bridge Type 8 (INTERBUS) and Type 10 (Ethernet-based) communication systems.
- Performance Indicators: Establishes requirements for key performance metrics such as delivery time, throughput, network topology, redundancy recovery, and synchronization accuracy.
- Normative References: Relies on a range of related standards, including IEC 61158, IEC 61784-1-6, IEC 61784-2-0, and numerous IEEE and IETF protocols for Ethernet communication.
