Overview
IEC 61784-1-16:2023 is an international standard published by the International Electrotechnical Commission (IEC) focusing on industrial communication networks. It defines Communication Profile Family 16 (CPF 16), a set of communication profiles specifically for fieldbus technologies used in factory manufacturing and process control. CPF 16 builds upon protocol definitions from the IEC 61158 series-particularly Type 16 and Type 19 protocols-and other relevant standards.
This standard provides detailed protocol-specific communication profiles (CPs) that guide the design and implementation of devices communicating over industrial networks. These profiles specify consistent subsets of services and protocol functions, including any constraints on parameter values to ensure interoperability and reliable communication.
Key Topics
-
Communication Profile Family 16 (CPF 16): CPF 16 encapsulates a family of protocol-specific communication profiles relevant to fieldbus technology implementations in industrial settings.
-
Protocol Basis: CPF 16 relies on protocols defined in IEC 61158 (Types 16 and 19), ensuring standardized and interoperable communication layers.
-
Profile Definition: Each communication profile selects an appropriate subset of services and protocols from the larger IEC 61158 protocol family and details necessary constraints to maintain compatibility and performance.
-
Standards Integration: CPF 16 profiles reference other IEC International Standards or open standards developed by IEC or other standards bodies, maintaining broad acceptance and compliance.
-
Focus on Factory Automation and Process Control: The profiles in CPF 16 are tailored for industrial automation systems, including factory manufacturing and process industries where reliable, real-time communication is crucial.
-
Technical Structure: CPF 16 encompasses definitions for physical layers (PhL), data-link layers (DLL), and application layers (AL), providing a comprehensive protocol stack specification.
