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

Abstract

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.

Methodological Approach for Developing Reconfigurable Automation Systems

“…Besides, it is not clear who decides if the failure is recoverable and how, as the domain expert is not involved. Merz et al [23] present a method for dynamic reconfiguration by means of runtime deployment. Reconfiguration times are acceptable although they are highly dependent on the control software, the underlying hardware, and the deployment algorithm.…”

Self-organizing multiagent mechatronic systems in perspective

“…Industrial adoption of agent technology has been elusive so far although several studies have reported tests in industrial setups ([1, [16][17][18] and [19] for a recent case).…”

Ingeniería conducida por modelos en sistemas de automatización flexibles

“…Este trabajo usa dicho término como la capacidad de reubicar las diferentes funcionalidades sobre el sistema de control distribuido con objeto de optimizar algún tipo de calidad de servicio. Por ejemplo: rendimiento del controlador [6], consumo de la batería [8] o la continuidad del servicio a pesar de fallo en el controlador o en la red [14], [19]. Sin embargo, la integración de los mecanismos de reconfiguración dentro de los sistemas de producción de automatización implica un aumento de su complejidad en términos de tamaño, funcionalidad y distribución, lo que hace que su diseño y desarrollo sean más complejos.…”
