Abstract
In the era of Industry 4.0, manufacturing systems require essential capabilities of rapid-reconfiguration and autonomous operations. Many studies have been conducted to generate flexible plans and optimize task sequences at the shop floor system-level. However, little attention have paid on how to connect these task plans to the actual execution of field devices. Therefore, this paper proposes the concept and architecture of active driver wrapper (called linker) for improvised and interactive task execution. The linker architecture includes the definition for digital representation of devices and hardware abstraction to facilitate us to rapidly change the logical and physical configurations of manufacturing systems. In addition, each linker can proactively respond to the faulty situations of devices via peripheral intelligence. Four case studies were conducted to evaluate the potentials of the proposed architecture.
