Programmable controllers - Part 6: Functional safety
IEC 61131-6:2012 specifies requirements for programmable controllers (PLCs) and their associated peripherals, as defined in Part 1, which are intended to be used as the logic subsystem of an electrical/electronic/programmable electronic (E/E/PE) safety-related system. A programmable controller and its associated peripherals complying with the requirements of this part is considered suitable for use in an E/E/PE safety-related system and is identified as a functional safety programmable logic controller (FS-PLC). An FS-PLC is generally a hardware (HW) / software (SW) subsystem. An FS-PLC may also include software elements, for example predefined function blocks.

Automates programmables - Partie 6: Sécurité fonctionnelle
La CEI 61131-6:2012 spécifie les exigences pour les automates programmables (PLC) et leurs périphériques associés, comme défini dans la Partie 1, visant à être utilisés comme sous-système logique d'un système électrique/électronique/électronique programmable relatif à la sécurité. Un automate programmable et ses périphériques associés, conformes aux exigences de cette partie, sont considérés comme appropriés dans un système électrique/électronique/électronique programmable relatif à la sécurité et sont identifiés comme un automate programmable de sécurité fonctionnelle (FS-PLC). Un FS-PLC est généralement un sous-système matériel ou logiciel. Un FS-PLC peut également inclure des éléments logiciels, par exemple des blocs fonctionnels prédéfinis.
Programirljivi krmilniki - 6. del: Funkcionalna varnost (IEC 61131-6:2012)
Ta del skupine standardov IEC 61131 določa zahteve za programirljive krmilnike (PLC) in pripadajoče periferne naprave, kot so opredeljene v 1. delu in se uporabljajo kot logični podsistem električnega/elektronskega/elektronsko programirljivega (E/E/PE) varnostnega sistema. Programirljivi krmilniki in pripadajoče periferne naprave, ki izpolnjujejo zahteve iz tega dela, so primerni za uporabo v električnem/elektronskem/elektronsko programirljivem varnostnem sistemu in opredeljeni kot funkcionalno varni programirljivi logični krmilniki (FS-PLC). Funkcionalno varni programirljivi logični krmilniki so običajno podsistem strojne (HW)/programske (SW) opreme. Funkcionalno varni programirljivi logični krmilniki lahko vključujejo tudi elemente programske opreme, na primer predprogramirane funkcijske bloke. Električni/elektronski/elektronsko programirljivi varnostni sistem je na splošno sestavljen iz senzorjev, stikal, programske opreme in logičnega podsistema. Ta del je namenjen izvajanju posebnih zahtev za izdelke iz skupine standardov IEC 61508, zato izdelki, ki so v skladu s tem delom, izpolnjujejo vse veljavne zahteve iz skupine standardov IEC 61508 v zvezi s funkcionalno varnimi programirljivimi logičnimi krmilniki. Skupina standardov IEC 61508 je sistemski standard, ta del pa določa posebne zahteve za izdelke glede uporabe načel skupine standardov IEC 61508 pri funkcionalno varnih programirljivih logičnih krmilnikih. Ta del skupine standardov IEC 61131 obravnava samo zahteve glede funkcionalne varnosti in varnostne celovitosti funkcionalno varnih programirljivih logičnih krmilnikov, kadar so del električnega/elektronskega/elektronsko programirljivega varnostnega sistema. Opredelitev zahtev funkcionalne varnosti za celotni električni/elektronski/elektronsko programirljivi varnostni sistem in zahteve funkcionalne varnosti za končno uporabo električnega/elektronskega/elektronsko programirljivega varnostnega sistema ne spadajo na področje uporabe tega dela, vendar so podlaga zanj. Informacije, specifične za uporabo, so navedene v standardih, kot je skupina standardov IEC 61511, standard IEC 62061 in skupina standardov ISO 13849. Ta del ne zajema splošnih varnostnih zahtev za funkcionalno varne programirljive logične krmilnike, kot so zahteve v zvezi z nevarnostjo električnega udara in požara, ki so navedene v standardu IEC 61131-2. Ta del se uporablja za funkcionalno varne programirljive logične krmilnike, ki lahko dosežejo največ 3. stopnjo varnostne celovitosti (SIL).
