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.
摘要:
An automated event viewing method for a process control network that includes a plurality of distributed control system (DCS) servers that receive process event data from one or more industrial processes, wherein each DCS server is connected to one or more operator consoles for monitoring the one or more industrial processes. The method includes receiving process event data of the industrial processes in real time from the plurality of DCS servers and transmitting in real time the process event data of the industrial processes to one or more operator consoles that are not connected to the DCS server from which the process event data originated.

A distributed big data device in a process plant includes an embedded big data appliance configured to locally stream and store, as big data, data that is generated, received, or observed by the device, and to perform one or more learning analyses on at least a portion of the stored data. The embedded big data appliance generates or creates learned knowledge based on a result of the learning analysis, which the device may use to modify its operation to control a process in real-time in the process plant, and/or which the device may transmit to other devices in the process plant. The distributed big data device may be a field device, a controller, an input/output device, or other process plant device, and may utilize learned knowledge created by other devices when performing its learning analysis.
摘要:
System(s) and method(s) are provided for peer-to-peer exchange of data in a control system. Decentralized storage and multi-access paths provide complete sets of data without dependence on a specific or pre-defined data source or access paths. Data is characterized as data resources with disparate granularity. The control system includes a plurality of layers that act as logic units communicatively coupled through access network(s). Server(s) resides in a service layer, whereas client(s) associated with respective visualization terminal(s) are part of a visualization layer. Peer-to-peer distribution of data resource(s) can be based on available access network(s) resources and optimization of response time(s) in the control system. When client requests a data resource, all the locations of the data resource and the quickest source to retrieve it are automatically determined. The client stores copy of data resource. Peer-to-peer distribution of data resource(s) can be implemented within the service layer or the visualization layer.

摘要:
In a complex plant most of the problems or errors will occur only once. Therefore corrective maintenance and trouble-shooting staff can not go back or hark back to ready-made solutions for these problems or errors. The present invention provides a method and a computerized system which enables the corrective maintenance and trouble-shooting staff having access to experiences made on third party plants regarding these problems or errors.
摘要:
A system and method provide the creation and operation of remote real-time data monitoring and control systems. Such applications include a communications gateway coupled to real-time devices. The communications gateway transforms the real time data collected from disparate and non-interoperable systems in a single common data format. The communications gateway provides an object server with a list of the real-time devices to which the communications gateway is connected, and their attributes. The object server publishes this list. Subscribers can access this list, and request subscriptions to specific attributes of certain devices. The object server creates a data object corresponding to the requested information. A subscriber includes a service agent which accesses the object server. In addition, a subscriber may also comprise presentation cells, which provide a representation and mapping of data objects and hence underlying devices and systems, to allow a user to manage and control such systems. Subscribers including presentation cells may be personalized to function as personal agents. Such personal agents can be programmed to monitor and control certain subsystems, and to alert certain people when specific events occur in these subsystems.

The problem addressed by the invention is to operate an electrical component (16) in a cyber-physical system (22). The adapter device (36) provided according to the invention for coupling the component (16) to a data network (20) of the cyber-physical system (22) comprises: a communication unit (40) which is designed to receive defined request data (24) from the data network (20) independently of the component; an interpretation unit (50) which is designed to determine a command (68) executable using the technical features of the component (16) depending on the request data (24); an assessment unit (52) which is designed to generate a potential solution (70′) to the command (68) comprising at least one control signal (32) for the component (16) depending on operating data of the component (16); and a controller (66) which is designed to issue the at least one control signal (32) of the potential solution (70′) to a control interface (30) of the component (16).
摘要:
Various amounts of information can be beneficial to different controllers configured upon an industrial control system. Information can be retained in a distributed directory such that controllers quickly learn information concerning other controllers. The distributed directory can be automatically constructed and populated with information from different controllers. When a module enters an industrial control system, information can automatically advertise to other units through use of the distributed directory.
摘要:
A process control system includes multiple zones containing process control network communicatively interconnected to exchange information necessary to monitor the system and to perform process control. Each zone may include an inter-zone server that controls the exchange of information between the zones via communication links. In addition to controlling the routing of information between the zones, the inter-zone servers may perform additional processing on the information being exchanged, such as security monitoring, language translation and version control.
