    摘要: A system (100) and method for remotely monitoring and controlling time variant data in an industrial plant (400). The system (100) includes a local server (102) and at least one remote server (104). The local server (102) includes a local server cache (206), a local controller (308), and a local operator station (1001). Each remote server (104) includes a remote server cache (901) and a remote controller (903). Wherein the local server cache (206) stores a plurality of data units (304), and the local controller (308) provides updated units (902) to the local server cache (206). Each remote server cache (901) stores a plurality of data units (902), and each remote controller (903) provides updated data units (902) to its corresponding remote server cache (901). The method operates such that each cache (206, 901) buffers controllers (308) and other servers (104) from unnecessary data requesting transactions, minimizing the data traffic in the system (100). A communication network hardware in the form of a Wide Area Network (WAN) (106) interconnecting all the servers (102, 104), and a unique data point identifier (204) associated with the at least one remote server (104) are also disclosed.

    摘要: The present invention provides systems and methods for controlling processes of a process facility and, in particular, for distributing data among nodes of a real time process control system controlling such a facility. An exemplary process control system includes a plurality of sensors, controllable devices, and communication paths, and a computer system. The sensors and controllable devices are associated with various ones of the processes of the process facility, and the communication paths couple the sensors and controllable devices to the computer system. The computer system operates on data related to the process facility, and distributes the data among both client and process nodes. The client nodes desire data associated with processes of the facility and the process nodes control such process data. The computer system includes (i) a cache having a short access time for retrieving records, and (ii) a supervisory controller, associated with the client and process nodes, that controls storage of the process data in the cache and selectively transfers the process data from the cache to the client nodes.
