Dynamic redeployment of control software in distributed industrial automation systems during runtime

Current research on the reconfiguration of automated industrial manufacturing systems focuses mainly on the reconfiguration of the production process. For uninterrupted operation also the distributed control system has to allow for reconfiguration during runtime. In this paper a method for dynamic redeployment of control software during runtime is presented, comprising a structural and behavioral concept. To enable this dynamic redeployment, control hardware faults are detected and the control software deployment is adjusted to the smaller number of controllers. Likewise, additional hardware resources are integrated to the system. An implementation and evaluation within a demonstration scenario shows the feasibility of the concept.
