A complete automatic monitoring of all safety aspects of a production system? This is what TÜV SÜD Product Service and the Fraunhofer IOSB-INA are striving for together with other partners under the umbrella of the Center for Industrial IT (CIIT).
In the it's OWL technology network, essential technological prerequisites for modular and flexible production systems have been created. The increasing networking of sensor, actuator and control systems beyond the physical limits of the machine enables the integration of new services and production processes. The boundaries between operational technology (OT) and information technology (IT) are softened and with it the otherwise clearly recognisable limits of a machine. However, this is the basis for already developed Self-X technologies (self-optimisation, self-configuration, artificial intelligence).
In industrial practice, these have so far been used only cautiously. A major reason for this is that a free reconfiguration of a production plant always requires a new safety assessment. The associated analyses and certifications are complex and are now carried out manually by experts.
To take advantage of the efficiency gains and time savings that can be achieved by using Self-X technologies for reconfiguration, TÜV SÜD, Fraunhofer IOSB-INA and other partners of the Center for Industrial IT (CIIT) are working on the following topics:
- Modular certification
- Extended hazard and risk assessment
- Identification of value-added business models for the machine safety sector
- Semantics, modelling, digital twin for maintaining and monitoring machine safety
- Interoperable collaborative solutions in machine safety
- Safety-related communication with OPC UA Safety
In the it's OWL technology project ‘AutoS2’ the requirements for the automation of risk assessment are determined and a possible semantics for the administrative shell is defined and implemented. The third component is the implementation of an evaluation algorithm that performs the risk evaluation automatically.
