Industrial communication networks - Profiles - Part 3-1: Functional safety fieldbuses - Additional specifications for CPF 1 (IEC 61784-3-1:2007); English version EN 61784-3-1:2008
This part of the IEC 61784-3 series specifies a safety communication layer (services and protocol)
based on CPF 1 of IEC61784-1 and IEC61158 Type 1 and 9. It identifies the principles for
functional safety communications defined in IEC61784-3 that are relevant for this safety
communication layer.
NOTE 1 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as
electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.
This part1 defines mechanisms for the transmission of safety-relevant messages among participants
within a distributed network using fieldbus technology in accordance with the requirements of
IEC61508 series for functional safety. These mechanisms may be used in various industrial
applications such as process control, manufacturing automation and machinery.
This part provides guidelines for both developers and assessors of compliant devices and systems.
NOTE 2 The resulting SIL claim of a system depends on the implementation of the selected functional safety
communication profile within this system - implementation of a functional safety communication profile according to this
part in a standard device is not sufficient to qualify it as a safety device.
