  • Patent number: 8966028
    Abstract: A modular distributed I/O system for an industrial automation network that allows one or more modules of an island to be omitted without requiring reconfiguration of the system by maintaining a consistent I/O image representation of the distributed I/O network for various physical distributed I/O configurations, and managing reconfiguration changes using Virtual Placeholder objects.

  • Patent number: 8904074
    Abstract: The invention described herein provides a system and method for distributing and applying a configuration file from a master device (102) to a slave device (104) in a distributed control system (100). According to aspects of the invention, a configuration file is saved at a master device (102) and distributed to the slave device (104) via the data payload of a fieldbus protocol, such as the CANopen protocol. Aspects of the present invention may be used to further configure an I/O island or sub-network (108) that is attached to the slave device (104). Further aspects of the present invention may be used to repair or replace failed devices in a distributed control system (100).

  • Patent number: 8634325
    Abstract: Each device in an industrial automation system network or other network may have its own associated one or more performance characteristics, such as response time and/or reset time of the network device. Data may be stored representing a plurality of performance characteristics each associated with a different one of a plurality of devices in the network including a first device and a second device. The stored data may be retrieved, representing the performance characteristic of the second device. The first device may communicate over the network with the second device in accordance with the performance characteristic of the second device.

  • Publication number: 20130198408
    Abstract: An enhanced Internet Protocol (IP) parameter device may aid in configuring and/or determining the IP parameters of a device. The enhanced IP parameter device may first wait for a message requesting a network address from the device. This message may be sent using a variety of communication protocols, including Bootstrap Protocol (BOOTP) and Dynamic Host Configuration Protocol (DHCP). Once this message is received, a handshaking procedure may be completed and the enhanced IP parameter device may then transmit IP parameters to the device. Alternatively, the device may also transmit a message using Address Resolution Protocol (ARP) to allow the enhanced IP parameter device to determine the IP address assigned to the device. Finally, if the device does not transmit any message, the enhanced IP parameter device may search a predetermined range of IP addresses or use Inverse Address Resolution Protocol (IARP) or Reverse Address Resolution Protocol (RARP).
