適用范圍：This part of the IEC 61784-3 series specifies a safety communication layer (services andprotocol) based on CPF 18 of IEC 61784-2 and IEC 61158 Type 22. It identifies the principlesfor functional safety communications defined in IEC 61784-3 that are relevant for this safetycommunication layer.NOTE 1 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards suchas electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.This part1 defines mechanisms for the transmission of safety-relevant messages amongparticipants within a distributed network using fieldbus technology in accordance with therequirements of IEC 61508 series2 for functional safety. These mechanisms may be used invarious industrial applications such as process control, manufacturing automation andmachinery.This part provides guidelines for both developers and assessors of compliant devices andsystems.NOTE 2 The resulting SIL claim of a system depends on the implementation of the selected functional safetycommunication profile within this system – implementation of a functional safety communication profile according tothis part in a standard device is not sufficient to qualify it as a safety device.
