Conference Object The Implementation of Dynamic Distributed Real Time Industrial Communication Protocol (D 2rip)(2012) Gözcü, A.K.; Turan, U.; Schmidt, E.G.; Schmidt, K.W.Ethernet is a popular technology for industrial networking thanks to its low cost and high bandwidth. The current proposals to achieve real-time communication over Ethernet do not consider the determinism of the control applications resulting in inefficient use of bandwidth resources. We proposed a protocol stack architecture that works with standard Ethernet to address this problem. This paper describes the implementation of this architecture over Real-time Linux operating system and the first experiments to verify the operation. The implementation and performance of IEEE 1588 protocol which provides the required synchronization is also presented. © 2012 IEEE.Conference Object The Verification of a Novel Framework for Real-Time Shared Medium Communication Network Protocols(2012) Kartal, Y.B.; Schmidt, E.G.; Schmidt, K.W.The subject of this work is the real-time communication of the distributed industrial control applications over shared-medium Ethernet. We developed a framework for the real-time communication protocols over shared-medium Ethernet in our previous work. The framework is designed using the Timed Input/Output Automata formalism to serve the changing real-time communication needs of the embedded control applications. In this paper we present the modeling, simulation and formal verification process of the proposed framework using UPPAAL toolbox. © 2012 IEEE.Conference Object Supervisory Control for Failure Recovery in Discrete Event Systems(2012) Schmidt, K.W.Discrete event system models are used for systems with a discrete state space and event-driven state transitions such as communication systems and manufacturing systems. This paper proposes a polynomial-time algorithm for the construction of fault-tolerant supervisors for discrete event systems. Such supervisor ensures the desired system behavior as long as no faults occur, and realizes a redundant behavior in case of faults. © 2012 IEEE.
