Industrijska komunikacijska omrežja - Profili - 3-8. del: Funkcijska varnost procesnih vodil - Dodatne specifikacije za CPF 8 (IEC 61784-3-8:2010)
Ta del serije IEC 61784-3 določa varnostno komunikacijsko plast (storitve in protokol) na osnovi CPF 8 IEC 61784-1 in IEC 61158 tipa 18. 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.
