Abstract-Today's manufacturing industries are undertaking efforts to further increase the flexibility of their facilities. One way to achieve this goal is the development of distributed, serviceoriented architectures (SOA). A challenge for SOAs is the continued support of the real-time requirements imposed by industrial control tasks. This paper presents an approach for executing service choreographies with strong real-time guarantees without a central point of control. Engineers can design the automation workflow as a graph of communicating tasks which are then assigned to devices in the network. Our method generates a cyclic, non-preemptive schedule for each device to achieve global cooperation between them. Using an approach that combines several heuristics, a valid solution for over 99% of the 1.2 million test cases was found. On average, this method was over two orders of magnitude faster than an approach based on MIP-solvers.

“…Traditional manufacturing plants do not scale well under these new requirements because the cost for installation and setup are constituting a considerable portion of their total life-cycle costs [1]. The problem stems from the inflexible design of traditional manufacturing systems: Centralized, monolithic and scan-based control systems are optimized for a given physical and network configuration.…”

Abstract-Today's manufacturing industry is under pressure to increase the flexibility of its factory lines. One approach to achieve this goal is the shift from centralized control systems towards distributed, service-oriented architectures (SOA). To fully leverage the benefit of this new paradigm, the SOA should extend down to the device level and even include resource-constrained devices, such as smart sensors and actuators. In this paper, we present our approach for a lightweight distributed service choreography without a central point of control. It is based on networkaware precalculation of a static, non-preemptive schedule for each device and is thus suitable even for constrained devices. In contrast to previous work, our focus lies on the planning components required for achieving a service choreography. Since scheduling is a central part of our architecture, and we expect it to be executed many times during the planning process, we evaluate different heuristics for this task.

Recently, new technologies have emerged in industrial automation platforms. A rapid modeling and simulation environment is required to integrate these new technologies with existing devices and platforms to reduce the design effort and time to market. System-level modeling is a popular design technique that provides early simulation, verification, and architectural exploration. However, integration of real devices with system models is quite challenging due to synchronization and hard real-time constraints in industrial automation. SystemC is the most commonly used system-level language in hardware-software codesign. However, SystemC lacks interfaces for the integration of system (virtual) models with real (physical) devices. We introduce the hybrid channel concept to clearly define the integration interface. Hybrid channel incorporates both real-tovirtual and virtual-to-real communication functions by solving synchronization issues while satisfying the real-time constraints.We successfully demonstrated the usability of our framework in industrial systems that utilize BACNet and Ethernet. We also developed a mathematical model that correctly estimates the results of our experiments. To the best of our knowledge, this is the first framework and mathematical model for SystemC in industrial automation domain.
