Glossary ATEX ATEX is an abbreviation of the French term "Atmosphère explosible" (potentially explosive atmosphere). ATEX stands for both EC directives in the area of explosion protection: ATEX product directive 94/9/EC and ATEX operating directive 1999/92/EC. Auxiliary power supply Auxiliary power supply refers to an electrical supply or reference voltage which some electrical circuits require apart from the standard supply.
Page 254 Glossary Fingerprint Numerical value generated by the device when you start safety validation via the "Functional Safety" wizard. By comparing the fingerprint, you determine whether or not the device and the safety-related parameters have changed erroneously during activation of the functional safety.
Page 255 Glossary Safety function Defined function executed by a safety-instrumented system with the objective of attaining or maintaining a safe system state by taking a defined hazardous incident into account. Example: Limit pressure monitoring Safety Integrity Level → Safety-instrumented system A safety-instrumented system (SIS) executes the safety functions that are required to achieve or maintain a safe state in a system.
