Industrial communication networks - Profiles - Part 3-3: Functional safety fieldbuses - Additional specifications for CPF 3 (IEC 61784-3-3:2010)
This part of the IEC 61784-3 series specifies a safety communication layer (services and protocol) based on CPF 3 of IEC 61784-1, IEC 61784-2 (CP 3/1, CP 3/2, CP 3/4, CP 3/5 and CP 3/6) and IEC 61158 Types 3 and 10. It identifies the principles for functional safety communications defined in IEC 61784-3 that are relevant for this safety communication layer. 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.

Ta del serije IEC 61784-3 določa varnostno komunikacijsko plast (storitve in protokol) na osnovi CPF 3 IEC 61784-1, IEC 61784-2 (CP 3/1, CP 3/2, CP 3/4, CP 3/5 in CP 3/6) in IEC 61158 tipov 3 in 10. Določa načela za funkcijsko varnost komunikacij, opredeljena v IEC 61784-3, ki so pomembna za to varnostno komunikacijsko plast. Ta del 1 opredeljuje mehanizme za prenos sporočil, pomembnih za varnost, med udeleženci znotraj porazdeljenega omrežja z uporabo tehnologije vodil v skladu z zahtevami IEC 61508 serije 2 za funkcijsko varnost. Ti mehanizmi se lahko uporabljajo v različnih industrijskih aplikacijah, kot je procesni nadzor, proizvodna avtomatizacija in stroji. Ta del zagotavlja smernice za razvijalce in ocenjevalce skladnih pripomočkov in sistemov.
