The safety of machines, plants and systems employed in industry depends more than ever before on the correct functioning of electronic control systems.
Malfunctioning of control systems can lead to unaccaptable risk, jeopardising both capital investments and people. To eliminate such risks as far as possible, the relevant control systems must meet exacting requirements in terms of functional safety.
For example we talk about "functional safety" when safety depends on the correct function of an electrical (E), electronic (E) and programmable electronic (PE) system (in short: E/E/PE systems). The following standards are used in this area.
