IEC 61158-6-10:2014

Overview

IEC 61158-6-10:2014 is an international standard developed by the International Electrotechnical Commission (IEC) that defines the application layer protocol specification for Type 10 elements in industrial communication networks. Specifically, it is part 6-10 of the IEC 61158 series which focuses on fieldbus specifications - a crucial technology in industrial automation for real-time distributed control.

This third edition, published in 2014, revises and replaces the second edition from 2010. It establishes the protocol for wire-representation of service primitives defined in IEC 61158-5-10 and specifies externally visible behaviours during their data transfer. The standard aligns with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545), ensuring broad interoperability and consistent network communication.

IEC 61158-6-10:2014 incorporates numerous technical advancements, enhancing performance and reliability for Type 10 fieldbus applications in industrial environments.
