La CEI 61784-3-12:2010 spécifie une couche de communication relative à la sécurité (services et protocole) fondée sur la CPF 12 de la CEI 61784-2 et le type 12 de la CEI 61158. Elle identifie les principes applicables aux communications de sécurité fonctionnelle définies dans la CEI 61784-3, et appropriés à cette couche de communication de sécurité. La présente version bilingue (2012-02) correspond à la version anglaise monolingue publiée en 2010-06.

Industrijska komunikacijska omrežja - Profili - 3-12. del: Funkcijska varnost procesnih vodil - Dodatne specifikacije za CPF 12 (IEC 61784-3-12:2010)

Ta del serije IEC 61784-3 določa varnostno komunikacijsko plast (storitve in protokol) na osnovi CPF 12 IEC 61784-2 in IEC 61158 tipa 12. Določa načela za funkcijsko varnost komunikacij, opredeljena v IEC 61784-3, ki so pomembna za to varnostno komunikacijsko plast. Ta del 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.
