Overview
IEC 61784-2-11:2023 is an international standard developed by the International Electrotechnical Commission (IEC) that defines Communication Profile Family 11 (CPF 11). This standard focuses on additional Real-Time Ethernet (RTE) communication profiles and network components based on ISO/IEC/IEEE 8802-3 standards. It complements the IEC 61784 series by specifying real-time industrial network profiles tailored for robust, high-performance automation applications.
CPF 11 profiles leverage IEC 61158 Type 11 protocols and incorporate amendments to existing standards, such as IEC 61588, to deliver real-time communication features over Ethernet networks. The document also outlines relevant performance indicators (PIs) and their relationships, enabling manufacturers and engineers to optimize and assess real-time communication networks effectively.
