GB/T 37085.308-2025 Industrial communication network—Profiles—Part 3-8:Functional safety communication profile of CC-Link family

Scope

This document specifies the safety communication layer (services and protocols) for CPF 8 based on IEC 61784-1, IEC 61784-2, and IEC 61158 types 18 and 23, and identifies the functional safety communication principles defined in IEC 61784-3 as relevant to the safety communication layer in this document. This safety communication layer is implemented only in safety devices.
Note 1: It does not include content related to electrical safety and intrinsic safety. Electrical safety involves risks such as electric shocks. Intrinsic safety relates to hazards associated with potentially explosive environments.
This document defines mechanisms for transmitting safety-related messages between participants in distributed networks using fieldbus technology, which comply with the functional safety requirements of the IEC 61508 series of standards. These mechanisms can be used in various industrial applications, such as process control, manufacturing automation, and machinery.
This document provides guidance for developers and evaluators of devices and systems that comply with this document.
Note 2: The final SIL declaration for a system depends on the implementation of the functional safety communication protocols selected within the system—implementing functional safety communication protocols in standard devices is not sufficient to prove that the device qualifies as a safety device.
