Increasing Flexibility and Availability of Manufacturing Systems - Dynamic Reconfiguration of Automation Software at Runtime on Sensor Faults

Design, modelling, simulation and integration of cyber physical systems: Methods and applications

“…In case real time is required PLCs are chosen here [USV14]. Dependability is guaranteed using a safety shell that allows only safe and non-destructive decisions of the agent to be conducted [WaVo08] during runtime. The agents' knowledge has instead been modelled [VGL15] during engineering as Parameter Diagram, but may also be learned during runtime.…”

Real-time capable software agents on IEC 61131 systems – Developing a tool supported method

“…The evaluation of a technical resource is done by the implementation of the operation "precision_tree" of a resource agent. Based on concept for a Fault-Tree-Analysis proposed by (Wannagat et al, 2008b), in this operation the ability of a resource agent to satisfy the process requirements can be evaluated. Due to the fact, that process requirements will also be represented by corresponding parameters of a resource agent, the evaluation consists of the calculation of these parameters inside the implementation of the operation "precision_tree".…”
