Functional safety for Industry 4.0 production

Safety for modular dynamic production

Developing the future of machine safety together

With the research focus on machine safety (smartSafety) for adaptive modular production, Fraunhofer IOSB-INA is addressing new challenges in the field of functional safety together with partners. In the following we inform you about:

 

Initial situation

Industry 4.0 requires modular, self-optimized and small-scale production that changes continuously. Production systems with such characteristics are regarded by the Industrie 4.0 platform as a changeable factory and are considered in application scenarios such as flexible production or changeable factory. The transformable factory can be quickly reconfigured to meet new production targets. For example, production units are removed, changed or added. The change can be, for example, the playing out of new configuration parameters that have previously been automatically determined by an AI-based optimization. A machine, the production module but also the production system, in which all units interact, must always be able to be operated safely. This causes production downtime and thus costs. These arise because today a safety officer must manually perform a hazard analysis and risk assessment for every change. In this way, it is checked whether all safety requirements from the Machinery Directive and the applicable regulations are met. Subsequently, technical documentation is often prepared manually. Conversely, this manual procedure reduces the cost-effectiveness of a convertible factory. Another aspect is that the safe condition of a machine usually means production downtime and thus causes further costs.

 

Developing the future of machine safety together

Based on the situation described above, we show you the need for action, work with you to find solutions and implement them. Together, we consider how new business models in the area of functional safety can be created with the new technologies. One research question, for example, is: In the future, does a safe condition have to mean a production stop? Can more safe states than just shutdown be found through ongoing automated risk assessment?

 

In the future, interoperability will be an important aspect in the development of solutions. To achieve interoperability, we bring our partners together in research projects and develop a uniform basis for individual interoperable implementations. In addition, our employees are involved in numerous standardization and technical committees. You can find an excerpt in the following sections or get in touch with your contact person.

 

Our competencies for functional safety

When developing solutions, the interdisciplinary know-how of our research groups is combined with the requirements of machine safety.

Our vision with smartSafety: An automatic risk assessment for Safety & Security for the continuous evaluation of the current threat risk. Realize solutions for the functional safety of tomorrow together with Fraunhofer IOSB-INA. Together we bring proven Industrie 4.0 technologies into safe profitable use.

In the following, you will find an excerpt of our competencies that form the basis for future technologies in the area of machine safety.Our employees will be happy to demonstrate the technologies of the future in our Real lab SmartFactoryOWL. Arrange an appointment with your contact person right now.
