Zastosowanie techniki RFID w związanych z bezpieczeństwem elementach systemów sterowania maszyn, zgodnie z wymaganiami zasadniczymi dyrektywy 2006/42/WE, wymaga odpowiedniego uwzględnienia właściwości tej techniki w procesie projektowania. Istotne jest uwzględnienie zaleceń i ograniczeń dotyczących stosowania techniki RFID i parametrów charakterystycznych urządzeń bezpieczeństwa stosujących tę technikę. Należy określić wymagania w obszarze zarządzania bezpieczeństwem funkcjonalnym, opracować specyfikację funkcji bezpieczeństwa, sformułować wymagania dotyczące projektowania i integracji odpowiednich elementów systemu sterowania, a następnie zrealizować proces projektowania. W końcu należy sporządzić informację dla użytkownika oraz przeprowadzić walidację całości projektu w celu potwierdzenia spełnienia wymagań.

The application of RFID technology in the safety elements of machinery control systems according to the essential requirements of directive 2006/42/EC requires to comply respectively the properties of this technology in the development process. It is important to comply the recommendations and restrictions of RFID technology application and the characteristic parameters of safety devices using this technology. The requirements in the area of functional safety management should be specified together with the safety function specification, the specification of requirements for design and integration of the suitable control system elements. Then the development process should be performed. At the end of this process the information for use should be elaborated and the validation should be performed to confirm the compliance with the requirements.

In the article the ProSIL software for computer aided functional safety management is presented. The software consists of three modules for the determination of the required SIL level (ProSILen) and verification of the SIL level (ProSILver). In the ProSIL the calibrated knowledge-based risk graph method for determining the required safety integrity level (SIL) of the safety functions identified in hazard analysis is implemented. The SILs are then verified for safety-related control and protection systems implementing relevant functions with regard to random failures and potential systematic failures. The assessment methods are compatible with international standards IEC 61508 and IEC 61511. Some current challenges and methodological issues concerning knowledge-based functional safety management in life cycle are also discussed.

The functional safety management in life cycle is a complex process starting with identifying hazards and defining safety-related functions (SRFs) with regard to the results of risk assessment oriented at determining the safety integrity level of consecutive functions. Another element of such process is a verification of required SIL for considered architectures of safety-related system that implements given safety function. Due to complexity of the problem, to overcome difficulties in safety-related decision making often under considerable uncertainties, usually without taking into account security aspects, we propose to apply the RIDM methodology oriented on functional safety management of programmable control and protection systems in life cycle taking into some more important risk-related factors identified.
