“…A proper designed period of the feed back message will benefit the real-time performance of the system. Moreover, the real-time performance, reliability and robustness of the novel fiber-CAN-based communication system is comparatively better than the traditional wire-CAN network, in which the probability of deadline missing is expected at the range of 10-4 [8]. The improvement attributes to the good capability in resisting the EMI, both from the new network structure and the optical fiber.…”

The voltage increment in MV-ASD systems deteriorates the electromagnetic environment, therefore the communication system is facing a formidable challenge in the attempt to achieve the numerous real-time interactivities among those subsystems under such electromagnetic circumstance. This paper focuses on the real-time communication system for the MV-ASD systems, in which electromagnetic compatibility (EMC), real-time performance and system reliability are considered simultaneously. A novel fiber-CAN network is designed and implemented, which remarkably increases EMC compared to the conventional ones. The CAN system that serves in the multiprocessor control system for the MV-ASD system with the rated power of 1MW is implemented. From the experiment results in the MV-ASD system with a 690kW motor, it can be verified that the requests of timing performance and the reliability for the communication system are well accomplished.

“…For example, Hansson et al used the probability of missing the packet transmission deadline to indicate the dependability of the network communication link [7]. Hu et al proposed a fault scanning scheme for online failure diagnosis [8], similarly, Winstead et al proposed an observer that uses transmission delays for fault detection in CAN [9].…”

Fieldbus technology plays an important role in manufacturing systems. Hence the reliability of the network is critical to the performance and the safety of the system. Among various factors that affect the reliability of the network, the intermittent connection (IC) of the network cable is a common but challenging troubleshooting problem since its location is difficult to identify. IC problems may result in degraded network performance, or system level failures in severe cases. In this paper, a novel model based fault location method is developed for IC problems on controller area networks (CAN). By passively capturing IC induced network errors, two sets of error events are defined for each node, based on which generalized zero inflated Poisson models are used to describe the patterns of the error events. A two-step IC fault location procedure is proposed by examining the statistical significance of the corresponding error events using the fitted models. Case studies are conducted to demonstrate the proposed method on different IC location scenarios. Experiment results show that the locations of the IC problems identified by the proposed method agree well with the experiment setup conditions.

“…The bounded transmission delay and worst‐case deadline analysis on controller area network (CAN)‐based networks have been comprehensively addressed in References4–6. Hasson et al 7 analyzed the CAN node timing responses in a noisy setup, and used the probability of missing the transmission deadline as a reliability indicator. The packet transmission delay analysis on other network structures was also studied in the literature.…”

Since the 1990s, the increasing deployments of networked automation systems led to increased manufacturing productivity, improved interchangeability of devices from different vendors, facilitated flexibility and reconfigurability for various applications and improved reliability, while reducing installation and maintenance costs. However, the reliability of a network has great impact on the reliability of a networked automation system. This paper presents a novel network reliability assessment method that provides diagnostic and prognostic information for DeviceNet. This work proposes a hybrid network error analysis method using combined physical and datalink layer features to provide complete communication log information. Furthermore, a network/node time to failure (bus-off) prediction algorithm was developed based on the analysis of the patterns of the interrupted packets on the network. The method developed in this study can be used for network reliability evaluation and diagnosis, facilitating better network maintenance decision making. A laboratory testbed was constructed and the experiments on network and node time to failure were conducted to demonstrate the concept. Experimental results show that the proposed method can fully reconstruct the communication log, and predict the network/node bus-off time successfully.
