    Abstract: To cause multiple field devices to operate together in coordination in accordance with a predetermined program through a network allowing periodic communication, a control device includes an estimator that calculates, based on a position of a first field device in a first cycle, a position of the first field device operable in accordance with a first program in a second cycle following the first cycle, and a processor that determines, based on the first program, a first command value to cause the first field device to operate, transmits the first command value to the first field device through an interface allowing communication with the field devices, determines, based on the estimated position and a second program, a second command value to cause a second field device to operate in coordination with the first field device, and transmits the second command value to the second field device through the interface.

    Abstract: Different devices or subsystems, including programmable industrial controllers, are connected to a common network. Each connected device has the capability for autonomous or quasi-autonomous action based on a common pool of information accessible on the network. For example, all or a subset of devices connected to the network may periodically broadcast status data over the shared network medium; status data may include the current state of the controller and/or environmental conditions that the controller monitors.

    Abstract: A PLC communication system includes a PLC; a plurality of devices; three or more communication processing nodes that are provided respectively in the PLC and the devices to allow the PLC to communicate with each of the devices; and a plurality of communication lines that connect the communication processing nodes to each other to allow data communication. The PLC detects an incommunicable state between two of the communication processing nodes. The PLC communication system further includes a display device, and in a case where there are a plurality of types of incommunicable states detected by the PLC, the display device displays a portion where communication lines constituting the incommunicable states among the plurality of communication lines overlap with each other, as a line failure portion.

    Abstract: A system for storing data in an industrial production environment includes a distributed database stored on a plurality of intelligent programmable logic controller devices. Each respective intelligent programmable logic controller device includes a volatile computer-readable storage medium comprising a process image area; a non-volatile computer-readable storage medium; a control application; an input/output component; a historian component; and a distributed data management component. The control application is configured to provide operating instructions to a production unit. The input/output component is configured to update the process image area during each scan cycle with data associated with the production unit. The historian component is configured to store automation system data comprising the operating instructions and contents of the process image area on the non-volatile computer-readable storage medium. The distributed data management component is configured to facilitate distributed operations involving the automation system data by the plurality of intelligent programmable logic controller devices.
