摘要： Methods and systems for integrating external and/or enterprise data into a process control system are disclosed. A user interface may be provided to enable browsing and selection of a data item from an external and/or enterprise data source. The selected data item may be associated with a process control entity. At run time, independent of a configuration of the process control entity, an external data integration server or instance of an external data integration service at a process control computing device may periodically communicate with the data source to obtain an updated current value and updated current status for the selected data item for use by the process control entity. The external data integration server and/or external data integration service may consolidate access of external/enterprise data across process control entities, optimize communications with various data sources, and maintain a status of communication with each various data source.

摘要： Disclosed are systems and methods for on-line monitoring of operation of a process in connection with process measurements indicative of the operation of the process. In some cases, the operation of the process is simulated to generate model data indicative of a simulated representation of the operation of the process and based on the process measurements. A multivariate statistical analysis of the operation of the process is implemented based on the model data and the process measurements. The output data from the multivariate statistical analysis may then be evaluated during the operation of the process to enable the on-line monitoring of the process involving, for instance, fault detection via classification analysis of the output data.

摘要： A process control system element for use in a process plant includes a process module, which represents a logical unit in the process plant, integrated with an expert module capable of detecting and/or mitigating abnormal situations associated with the logical unit. The process module may include a plurality of process objects, each process object representing a corresponding physical entity in the process plant. At least some of the process objects may include simulation capabilities to simulate the corresponding physical entities. The expert module may be adapted to detect at least one abnormal situation associated with the logical unit, and may be communicatively coupled to the process module to receive data from the process module during operation of the process module. Because the expert module is integrated with the process module, a user can more easily configure the expert module to detect and/or mitigate abnormal situations associated with the logical unit.

摘要： A method of routing a data packet between a first node and a second node on a communication network includes defining a first graph through the first node and the second node and zero or more intermediate nodes, associating several nodes which belong to the communication network with the first graph, associating a first unique graph identifier with the first graph and providing at least partial definitions of the first graph and the first unique identifier to at least some of the nodes associated with the first graph. The method then sends data packet with the graph identifier from the first node, and directs the data packet to the second node via the zero or more intermediate nodes using the graph identifier. This method may include forwarding the packet to a neighbor node of an intermediate node if the intermediate node and the neighbor node are nodes associated with the first graph and if the intermediate node and the neighbor node are connected by at least one direct communication connection.

摘要： A mesh communication network for use in, for example, process control plants includes a plurality of network devices transmitting and receiving data according to a network schedule defined as a set of concurrent overlapping superframes, and along a set of graphs defining communication paths between pairs of network devices. A network manager residing in or outside the communication network develops a routing scheme for the network by analyzing the topology of the network and defining a set of graphs for use in routing or transmitting data between various nodes of the network, each graph including one or more communication paths between pairs of network devices. Concurrently or consequently, the network manager defines the network schedule in view of at least transmission requirements, power availability, and signal quality at each network device. If desired, the network manager may begin to define the network schedule upon completing the definition of the graphs of the communication network, so that the network manager may define the network schedule in view both the defined graphs and the transmission, power, etc. parameters associated with each network device.

摘要： The present invention is a block oriented control system that allows interoperability between devices made by different manufacturers. A block oriented control system is a system which includes a plurality of field devices incorporating a physical layer, communication stack, and user layer, with the field devices being connected by a transmission medium, such as a bus. The physical layer receives signals from the bus and translates the signals into a message for the communications stack, and receives messages from the communications stack and translates the messages into signals for the bus. The communication stack controls the communications between devices operating in the control system. The user layer is a block oriented approach to the system's control functions, and includes function blocks and system management. The function blocks are standardized encapsulations of control functions, such as analog input or proportional/derivative. The system management allows synchronization of the device applications and the network processing.

摘要： A technique for controlling a process using non-periodically received process variable measurements enables more robust controller responses to setpoint changes. The control technique implements iterations of a control routine to generate a control signal using a reset or rate contribution component that produces an expected process response to the control signal. When a new measurement of the process variable is unavailable to the controller, the reset or rate contribution component that was generated in response to the receipt of the previous process variable is maintained when generating the control signal. However, the reset contribution component is iteratively recalculated during each controller execution cycle so that the output of the reset contribution component incorporates expected process changes that occur as a result of a setpoint change.

摘要： In order to reduce or eliminate aliasing in a process control network, filtering of a measurement signal may be set based on the module execution rate in a process control system. A Nyquist frequency for the module may be determined based on the module execution rate where the Nyquist frequency may be twice the execution rate. Filtering after an analog to digital convertor may be set based on the module execution rate. In the analog to digital convertor, digital filtering after the converter may be set based on the module execution rate and the frequency content of the analog signal may be attenuated by a filter at and above the Nyquist frequency for the module execution rate.

The method then sends data packet with the graph identifier from the first node, and directs the data packet to the second node via the zero or more intermediate nodes using the graph identifier. This method may include forwarding the packet to a neighbor node of an intermediate node if the intermediate node and the neighbor node are nodes associated with the first graph and if the intermediate node and the neighbor node are connected by at least one direct communication connection.
