In the ultra-flexible factory, production machines reconfigure themselves ad-hoc depending on incomingproduction orders. Consequently, the IFF institute has developed a modular cyber-physical system (CPS)that consists of configurable robotic components. This paper is motivated by the need to reduce the effortand time associated with the CE conformity process for manufacturing systems with frequentreconfigurations, thus minimizing non-value adding machine downtime and increasing Overall EquipmentEffectiveness (OEE). It presents an approach for an automated assistant system for the required riskassessment process using a database of previous CE conform system configurations and a reasoner that isable to verify the existence of a CE conform configuration that supersedes the hazards and risks of the newconfiguration. This allows the protective measures listed in the previous CE conform configuration to bereused, as well as a large part of the respective CE documentation.
