Analysis of industrial Ethernet POWERLINK multimaster redundancy
WIT Transactions on Information and Communication Technologies, 2014This paper describes the Managing Node (MN) realization method of redundancy in the Ethernet POWERLINK network. Through the monitoring network and control information updating to achieve the MN redundancy function. We give priority algorithm of redundant switching.

Virtual industrial Ethernet devices for testing purposes
Proceedings of 2012 IEEE 17th International Conference on Emerging Technologies & Factory Automation (ETFA 2012), 2012In this article an approach towards a modular generic field device, running on standard PC-hardware is presented. The work focusses on generating large numbers of software devices to be employed in stress test scenarios. The concept is based upon open source operating systems and virtualization.

Implementing Ethernet in the industrial environment
Forty-Second Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries, 2002It is pointed out that Ethernet or IEEE Std 802.3 CSMA/CD (carrier sense multiple access with collision detection) network technology has migrated from the research lab to the office to the factory floor. The factory floor challenges the integrity of this LAN (local area network) standard with high levels of noise, interference, and other environmental

Performance Analysis and Evaluation of Industrial Ethernet
2010 International Conference on Electrical and Control Engineering, 2010Because of a wide range of Industrial Ethernet and the great difference between them, it is a difficult problem to select which one is proper when designing an automation system. The huge advantages of Industrial Ethernet are discussed, so are the protocol model and technologic characteristics. The usage patterns and the usage percentages of industrial

Standardization of industrial Ethernet - the next battlefield?
IEEE International Workshop on Factory Communication Systems, 2004. Proceedings., 2005Roughly two years after the end of the fieldbus war, the IEC TC65 has started a new standardization project. The definition of a real-time Ethernet standard is a logical consequence of the introduction of Ethernet in industrial automation. Currently, several vendors have already introduced their approaches on the market or have at least finished ...

Redundancy enhancements for Industrial Ethernet ring protocols
2010 IEEE 15th Conference on Emerging Technologies & Factory Automation (ETFA 2010), 2010Ethernet ring redundancy is becoming a commodity in Industrial Ethernet environments. There are many ring redundancy protocols in existence, both standardized and proprietary. They all share the common disadvantage, that they can sustain only one fault in the network structure. A second fault results in parts of the network being unavailable.

Industrial Ethernet Protocol Wars: Fieldbus Revisited
2003Industrial Ethernet continues its march to lower levels of the plant hierarchy as both standards organizations and automation suppliers address criticisms of its suitability for plant floor applications. While Ethernet is an international standard, IEEE 802.3 specifies only the physical and data link layers of the 7-layer network stack. TCP/IP adds the
