What is BS EN 61131-6 - Programmable controllers for functional safety about?

BS EN 61131-6 is the sixth part of the multiple series document that 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. Note 1: BS EN 61131-6 does not cover general safety requirements for an FS-PLC such as requirements related to electric shock and fire hazards specified in IEC 61131-2. Note 2: BS EN 61131-6 applies to an FS-PLC with a Safety Integrity Level (SIL) capability not greater than SIL 3.
