A storage module may store at least a portion of the real-time digital recording. A real-time digital recording may contain at least a portion of the display image, wherein, at any particular time, the real-time digital recording includes information from the control system for a predetermined duration proximate the particular time, and at least a portion of the real-time digital recording may be stored. A desired portion of the digital recording may be played back, optionally with process control system event and/or continuous history.

摘要： A process plant includes a process control system having a safety system embedded therein. The integrated process control and safety system includes a host computer arranged to send and receive process level messages and safety level messages, a controller operatively connected to the host computer by a first communication network, at least one first input/output device adapted for operative communication with at least one process control field device, and at least one second input/output device adapted for operative communication with at least one safety-related field device. The first and second input/output devices are operatively connected to the controller via a second communication bus. The second input/output device includes a processor programmed to monitor both the process level messages and the safety level messages, to distinguish the process level messages from safety level messages, to select the safety level messages and to communicate with the safety-related field device based on the safety level messages.

摘要： A process control system integrates the collection and analysis of process control data used to perform certain computationally expensive process control functions, like adaptive model generation and tuning parameter generation, in the same control device in which one or more of the process control routines are implemented, to thereby provide for faster and more efficient support of the process control routines. This system replaces a layered approach using multiple processing devices by integrating an analytical server which performs computationally expensive analyses used by one or more control routines directly into the real-time control device in which the one or more control routines are located. This integration provides the ability to analyze large quantities of data for multiple process loops controlled by a particular device in a fast and efficient manner.

摘要： A controller includes a control module to control operation of a process in response to control data, a plug-in module coupled to the control module as a non-layered, integrated extension thereof, and a model identification engine. The plug-in detects a change in the control data, and a collects the control data and data in connection with a condition of the process in response to the detected change. The model identification engine executes a plurality of model parameter identification cycles. Each cycle includes simulations of the process each having different simulation parameter values and each using the control data as an input, an estimation error calculation for each simulation based on an output of the simulation and based on the operating condition data, and a calculation of a model parameter value based on the estimation errors and simulation parameter values used in the simulation corresponding to each of the estimation errors.
