An elevator group control system(EGCS) based on industrial network is introduced. Three layer networks of EtherNet/IP,ControlNet,and DeviceNet are employed in it. Elevator group control is implemented.
Due to adopting technology of socket and multithread, it makes information of Modbus protocol to be transmited in Internet and Intranet of TCP/IP protocol, more expanded application of Modbus protocol, and realized remote network communication in Modbus network that is made up of circuit breaker, it will be great operation significance in industry network of Modbus protocol.
In this paper, the development and applications of industrial communication and open industrial networks are discussed. In addition,key features of physical layer and communication stack of DeivceNet,DeviceNet deveice profile,DeviceNet objects,and DeviceNet interface are researched and clarified.
Drawing from flexible production literature on industrial networks, this research pays particular attention to the socially embedded nature of firm linkages in a distribution sector.
This paper is based on the knowledge gained from working with two industrial networks from the county of ?stfold in Norway.
The theme is innovation processes in industrial networks, with special attention on how it is possible to enhance the innovation capacity of the networks.
We discuss innovation processes in industrial networks as a part of regional innovation systems, because innovation processes in industrial networks cannot be fully understood without understanding how this also relates to the surroundings.
It indicates that not only is the ``regional advantage'' sufficiently sustained, but also the global industrial networks are continuously expanded to maintain the openness and dynamics of the region.
This paper describes the communication and industrial network between computer system levels and some of the current network tech -nologies that can be applied to improve system integration within iron and steel works, and presents individual requirements of networks between each two levels.
This paper discusses the structure and technical feature of read-time F-NET network designed for a advanced hicrarchical and distributed computer-based monitoring and control system. It also introduces the F-NET oriented BSJ-2200 integraled substation automation system.
A distributed process computer system using public telephone line as its telecommunication media is introduced. The hardware configuration of the system and software programming for telecommunication are described. The operational principles of common industrial networks and modems for distributed systems are discussed.
