This paper presents a novel approach to automation of flexible manufacturing systems with mechatronic intelligence and distributed control. The mechatronic intelligence layer is implemented using a combination of wireless sensor/actuator networks with service-oriented architecture, where services are located at the device level, as well as in local and global Clouds following the Arrowhead framework.
Time-driven and event-driven control models are two fundamental design paradigms applied in distributed control systems for synchronizing decentralized activities. This paper proposes a unified architecture for combining both approaches. The combination offers the best of both worlds’ properties, such as the expressiveness of event-driven programming and the determinism of time-driven logic. The foundations...
Distributed control systems are widely deployed to all areas in industrial automation. However, a systematic approach to the design and programming of distributed automation and control systems is not clearly defined. This paper analyzes the differences between two control system architectures defined in IEC Standards — IEC 61131-3 for centralized control with programmable controllers (PLCs) vs. IEC...
