Connected worlds - but safe! Functional safety under Industry 4.0

Systems consisting of electrical and electronic components have been used for many years to perform the safety functions in a wide variety of applications. Computer-aided systems (programmable electronic systems, abbreviated to PES) are now in use in all areas with safety-relevant applications. These systems often perform not only safety-relevant functions but also functions without safety classification. The conception and proof of the independence of safety-relevant components from uncritical functions is very important.

The beginning of any safety-related development is the hazard and risk analysis. This is used to determine the performance level (machine safety), integrity levels (vehicles) or an assurance level (aerospace). The selection of the safety standard relevant to you and the methodological determination of the safety classification and formulation and quantification of the safety objectives in expert workshops are services that are performed by the consultants of the AVQ.

Project Managers and Engineers have an obligation and responsibility to comply with the requirements of the Standards for Functional Safety Management (FSM) for all phases of the safety lifecycle.

Thus, in the development of safety-related components and systems as well as in their application, organizational and error-avoiding measures must be repeatedly verified or validated. This requires special methods and organizational procedures, which must be fulfilled from an economic and schedule point of view. It makes sense to integrate these methods as part of an FSM system not only project-related but fundamentally in a company.

Functional safety methodologies provide concepts and evidence that the safety-related systems provide the required risk minimization.

In principle, a distinction must be made in systems with additional safety functions and so-called intrinsically safe systems. From the introduction of a security layer into the system architecture to the most diverse forms of redundancy, there is a wide range of possibilities to increase the security integrity of a system.

In addition to the creation of individual work products up to the entire safety case according to the industry or application-specific safety standard, AVQ supports throughout the safety lifecycle and offers both Functional Safety Engineering and Functional Safety Management of your safety-related project.
