Overview

EN IEC 61784-2-14:2023 (IEC 61784-2-14:2023) defines Communication Profile Family 14 (CPF 14) - a set of additional real‑time fieldbus profiles based on ISO/IEC/IEEE 8802-3 (Ethernet) and the IEC 61158 series (Type 14). The standard specifies Real‑Time Ethernet (RTE) communication profiles (CP 14/1 … 14/4), related network components, and the RTE performance indicators and their dependencies required to achieve deterministic, time‑sensitive communications in industrial networks. CPF 14 may reference or amend standards such as IEC 61588 (precision clock synchronization) and IEEE 802.1 family protocols to provide real‑time features.

Key topics and technical requirements

• CPF 14 scope: Defines RTE communication concepts, network topologies, and EPA (Ethernet‑based Process Automation) device roles.
• Profile set: Includes individual communication profiles (CP 14/1, CP 14/2, CP 14/3, CP 14/4). For each profile the standard addresses:
  • Physical layer requirements
  • Data‑link layer (DLL) services and protocol choices
  • Network, transport and application layer considerations
  • Selection and mapping of application layer (AL) services and protocols
• Performance indicators (PIs): Specifies relevant RTE PIs (e.g., latency, jitter, availability) and defines dependency matrices and consistent PI sets so system designers can validate deterministic behavior.
• Interoperability and amendments: Profiles are based on IEC/ISO/IEEE publications (IEC 61158, IEEE 802.1, ISO/IEC/IEEE 8802‑3) and may include normative references and permitted amendments to achieve required RTE characteristics.
• Documentation and conformity: Includes normative references, terminology, symbols and tables to guide implementation and testing.

Applications and who uses it

EN IEC 61784-2-14:2023 is intended for:

• Industrial automation architects designing deterministic Ethernet networks for process and factory automation.
• Device and switch manufacturers implementing RTE features and ensuring compliance with CPF 14 profiles.
• System integrators and OEMs selecting communication profiles to meet application latency, jitter and availability targets.
• Test labs and certification bodies verifying conformity, interoperability and performance indicator compliance. Typical applications: time‑sensitive control loops, distributed I/O, real‑time process automation, and any industrial systems requiring predictable Ethernet communications.

Related standards

• IEC 61158 series (Fieldbus specifications, Type 14)
• ISO/IEC/IEEE 8802-3 (Ethernet)
• IEC 61588 / IEEE 802.1AS (time synchronization)
• IEEE 802.1Q (bridging/vlan), IEEE 802.1AB (LLDP)
• IEC 61784-2-0 (general concepts for RTE profile families)

EN IEC 61784-2-14:2023 is a practical reference for implementing Real‑Time Ethernet and CPF 14 profiles to achieve deterministic, interoperable industrial network solutions.
