    摘要： A clustered automation platform includes a plurality of distributed autonomous junction boxes connected to a master autonomous junction box, wherein each of the distributed autonomous junction boxes is configured to connect to one or more process measurement and control devices. The clustered automation platform also includes a fault-tolerant local area Ethernet network configured to interconnect the master autonomous junction box with a fault-tolerant input/output system server and a fault-tolerant control server. The clustered automation platform also includes a plurality of virtual local area networks partitioned from the fault-tolerant local area Ethernet network, a plurality of virtual control modules virtualized from the fault-tolerant control server, and a plurality of virtual operation areas virtualized from the fault-tolerant input/output system server. The clustered automation platform also includes real-time DDS middleware configured to interconnect hardware components with virtual components of the clustered automation platform.

    摘要： A collaborative automation platform includes a control server connected to a local area control network, and a plurality of distributed autonomous process interface systems. Each distributed autonomous process interface system is configured to receive measurement data from one or more field instruments and forward converted measurement data via an uplink to subscribers. Each distributed autonomous process interface system includes a standalone data distribution system-enabled input/output system and associated hardware for connection to the one or more field instruments. The collaborative automation platform also includes real-time DDS middleware configured to interconnect process control applications of the control server with the plurality of distributed autonomous process interface systems. The collaborative automation platform is configured with circuitry to determine unmeasured process properties required for higher level process control applications, publish changed values of the converted measurement data to the subscribers, and publish the unmeasured process properties to the subscribers.
