CENELEC - EN 61784-3-6

Industrial communication networks - Profiles - Part 3-6: Functional safety fieldbuses - Additional specifications for CPF 6

active, Most Current
Organization: CENELEC
Publication Date: 1 August 2010
Status: active
Page Count: 92
ICS Code (Industrial process measurement and control): 25.040.40
ICS Code (Multilayer applications): 35.100.05
scope:

This part of the IEC 61784-3 series specifies a safety communication layer (services and protocol) based on CPF 6 of IEC 61784-1, IEC 61784-2 and IEC 61158 Type 8. It identifies the principles for functional safety communications defined in IEC 61784-3 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 IEC 61508 series2 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.

1 In the following pages of this standard, "this part" will be used for "this part of the IEC 61784-3 series".

2 In the following pages of this standard, "IEC 61508" will be used for "IEC 61508 series".
