摘要： A device description language (DDL) converter is provided for converting a first DDL file into one or more second DDL files. The DDL files may be associated with wireless field devices that are or could be used in a process control system, such as wireless sensors or wireless actuators. The DDL files may contain information associated with parameters of the field devices, such as tunings, performance statistics, statuses, measurements, and other data of interest. The first DDL file could be associated with a non-standard DDL. The one or more second DDL files could be associated with standard DDLS, such as HART, Foundation Fieldbus, and Profibus DDLs.

摘要： An apparatus is provided for facilitating integration of a wireless field device (such as a wireless sensor or actuator) and a wired protocol that is used in a process control system. The apparatus supports a wireless field device protocol for communicating with the wireless field device. The apparatus also supports a wired field device protocol for communicating with other components of the process control system over a network.

摘要： An alarm recovery method and device for regenerating a list of alarm state values of a device after loss of communication or other discontinuity in processing is disclosed. The method and device are implemented in a control system for the control of a process. In normal operation the device sends notification messages on a high priority basis to a computer to update the alarm state values of a list. When communication is lost and then resumed, or other discontinuity of processing occurs and is restored, the recovery procedure begins by notifying the notification manager of the start of the notification process, saving alarm condition disable states, disabling each enabled alarm condition, allowing the device to generate return-to-normal notifications, restoring the original alarm condition disable states, allowing the device to generate appropriate current active alarm notifications, and notifying the notification manager of the end of the notification process. The notification manager reliably re-synchronizes the alarm states since the re-generated alarms are communicated at the same priority as the new alarm state changes, preventing mis-matches possible with other alarm state-access methods.

摘要： A method for improving a link schedule used in a communications network is disclosed. While the method applies generally to networks that operate on a scheduled communications basis, it is described in the context of a Foundation FIELDBUS. The method includes: scheduling sequences and their associated publications according to their relative priority, per application; minimizing delays between certain function blocks, and between certain function blocks and publications; and grouping certain publications. Accordingly, advantages such as latency reduction, schedule length reduction, and improved communications capacity are gained.

摘要： A system for integrating a wireless network with wired field devices includes a field unit that communicates with the wired field devices using a first wired field device protocol. A gateway wirelessly communicates with the field unit and communicates over a network using one or more second wired field device protocols. The gateway also converts between the first wired field device protocol and the one or more second wired field device protocols. The gateway could further permit access to the wired field devices by a component of the process control system (such as a process controller, asset management tool, or configuration tool) that does not support the first wired field device protocol. At least one of the field unit and the gateway could appear as a multiplexer or linking device to the component of the process control system, such as a HART multiplexer or a Foundation Fieldbus or Profibus linking 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.
