Reference EN 61784-3:2010
Title Industrial communication networks - Profiles - Part 3: Functional safety fieldbuses - General rules and profile definitions
Project Number 22195
Abstract/Scope IEC 61784-3:2010(E) series explains some common principles than can be used in the transmission of safety-relevant messages among participants within a distributed network using fieldbus technology in accordance with the requirements of IEC 61508 series for functional safety. These principles can be used in various industrial applications such as process control, manufacturing automation and machinery. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. The main changes with respect to the previous edition are: - clarifications and additional explanations for requirements, updated references; - updates of definitions and requirements in relation with the new edition of IEC 61508; - addition of a new informative Annex D providing an assessment guideline; - addition of new parts for CPF 8, CPF 12, CPF 13, CPF 14; - in CPF parts, addition of an annex to provide information about test laboratories for testing and validating conformance of FSCP products.
