Supervision-based reconfiguration of industrial control systems

Current automation systems demand flexibility enough to meet the challenging requirements of applications in terms of complexity, extensibility or dynamism. From a global perspective the whole automation system must meet quality of service (QoS) requirements which can be, for instance, energy efficiency, load balance or full availability. This paper presents a reconfiguration-based architecture triggered by a higher level supervision that makes use of a component based middleware. The first step of the supervisory architecture is presented aiming at achieving the availability of the control system even in presence of control equipment failures.
