This standard provides requirements for the software of computer-based I%C systems supporting functions of safety categories B and C as defined by DIN EN 61226 (VDE 0491-1). It is not a general-purpose software engineering guide but is aimed to provide requirements that the software of I&C systems of safety classes 2 and 3 must meet to achieve the systems safety objectives. For requirements which are not specific to software the standard refers to DIN EN 61513 (VDE 0491-2), for hardware aspects to DIN EN 60987 (VDE 0491-3-1).
