    摘要： A data communications system is disclosed which uses a passive communications medium such as coaxial cable for communication between multiple stations connected to the bus. A token concept is employed such that when the token is owned by a station, it allows that station to transmit high level messages over the bus and to command, if desired, other stations to transmit high level messages to it. The communications system is primarily masterless with each station capable of token ownership using the same set of rules to determine the circumstances when perceived events by the station cause that station to change state. Improvements are presented in the initialization of a token list, the addition of stations to an existing token list, duplicate station address protection through random numbers associated with each station, power down patch out of a station from the token list, the joining of two networks (two token lists), timer period randomization, and the use of redundant communication mediums.

    摘要： The present invention is directed to an apparatus for communication with at least one device which resides on a standard communications network using a standard communications protocol. The apparatus has a scanner for scanning the device, a device scan table for storing data relating to the device, and a standard communications interface for interfacing between the device scanner and the standard communications network using the standard communication protocol. The present invention is also directed to a device scanner for a first device located on a first node of a standard communications network. The device scanner is provided for scanning devices on the standard communications network, and for identifying a second device on a second node of the standard communications network. The device scanner has an initiator for initiating a first communications command in a peer protocol format to the second node, a receptor for receiving from the second node a second communications command in the peer protocol format, in response to the first communications command, and an identifier for identifying the second device on the second node as a peer device. This apparatus and device can be used within a control system for monitoring input devices and for controlling output devices which reside on the standard communications network. The standard communications network can be an Ethernet network, and the standard communications protocol used therein can TCP using Modbus.
