  • Pointbus architecture and automatic sequential addressing
    Patent number: 7721079
    Abstract: A system for automatically configuring I/O devices is provided in accordance with the present invention. The system includes a plurality of I/O devices operatively coupled to each other and a sub-system for determining physical locations of the I/O devices with respect to one another. The sub-system assigns node addresses to each I/O device—each assigned node address corresponds to the physical location of the respective I/O devices.
    Type: Grant
    Filed: April 25, 2007
    Date of Patent: May 18, 2010
    Assignee: Rockwell Automation Technologies, Inc.
    Inventors: David S. Wehrle, Carl R. Schumaker, Gregg M. Sichner, John P. Caspers
  • Pointbus architecture and automatic sequential addressing protocol
    Patent number: 7412530
    Abstract: A protocol for configuring I/O devices is provided in accordance with the present invention. The protocol includes a first protocol for enabling at least one I/O module to receive network communications, and a second protocol for providing the network communications to the at least one I/O module. The first protocol enables at least one I/O module to enable at least one other I/O module to form an I/O group.
