This paper has a discussion on the new industrial protocol – EtherNet/IP protocol (EIP), which is a new standard of field bus standard. It is an open industrial networking standard that supports real-time I/O messaging, explicit message exchange. It uses commercial off-the-shelf Ethernet communication chips and physical media. In this paper we have done a detailed study on the composition of EIP packet, EIP command of its application, EIP message transfer and it industrial implementation architecture.

“…Network redundancy can be provided at different layers with respect to the ISO-OSI reference model and thus applied to different communication technologies. While for example [3] introduces a redundancy concept applied on transport layer, many other redundancy mechanisms are located at data-link layer. For industrial automation, highly reliable and real-time capable communication systems are required.…”

Reliability in automation networks is an important topic. Thus, redundant communication is fundamental in this context. In contrast to other automation domains, building automation networks facilitate Ethernet and IP communication and require reliable and predictable communication that are ideally based on standard network technologies. Since automation components are often based on commonly used operating systems, software-based solutions come into play. However, pure software-based solutions are inefficient and often infeasible due to limited processing resources. Thus, a hybrid redundancy concept is proposed that facilitates standard hardware components in combination with lightweight software modules. This paper presents a new redundancy mechanism for Ethernet networks based on a ring topology. This approach makes use of VLAN-capable Ethernet switches in combination with software modules for controlling the network traffic. Thereby, VLANs are used to provide physical redundancy by preventing from Ethernet loops. The proposed concept can therefore be used on different platforms and provides a transparent and reliable communication channel for automation applications. The concept is theoretically analyzed. Finally, a proof-of-concept shows the feasibility.

This paper describes the components and an addressing scheme for a sensor network in which the number and location of sensor nodes change dynamically. A sensor network is a network composed of various sensor nodes, and a sensor node consists of one or more CPUs, sensors, and a network interface. A sensor network, an organization of sensor nodes that are embedded in a wall, floor, electrical equipment, and nonelectrical equipment, can be used to support human action, the navigation of mobile robots, and other purposes. In comparison with a closed sensor network in a factory, they have the possibility to be moved somewhere without any notice given to the network management system. In order to operate such networks effectively and correctly, changes of the number and location of sensor nodes must be detected. In this paper, we discuss some fundamental components of such a network, and we call a network having these components an adaptive sensor network. They include position‐based addressing, an addressing scheme that can be generally applicable to the construction of such sensor network systems. With this addressing scheme, a data value is requested by using not an identifier but a location. The client that requests the data does not care whether there is a real sensor node at the location or not. We created a prototype of an adaptive sensor network system. It consists of a node management system, a node positioning system, and a human interface system for the sensor network. Through performance evaluation of the prototype, we concluded that it could follow dynamic changes due to either node failures or the motion of nodes. © 2000 Scripta Technica, Electron Comm Jpn Pt 3, 84(3): 62–71, 2001
