Many studies have been conducted to generate flexible plans and optimize task sequences in the shop floor system-level. However, little attention has paid on how to connect these task plans to the actual execution of field devices. Therefore, this study proposes the concept and architecture of active driver wrapper (to be called Linker hereafter) for improvised and interactive task execution. The Linker architecture defines the way of digital representation of devices and hardware abstraction that are essential to minimize turnover time to change logical instructions and physical configuration of manufacturing systems. In addition, each Linker can proactively respond to the abnormal situations of devices via peripheral intelligence. The potentials of the proposed architecture are demonstrated by three case studies of rapid factory reconfiguration and two industrial use cases of autonomous factory operation
