Patent number: 10018997Abstract: An on-line data analytics device can be installed in a process control system as a standalone device that operates in parallel with, but non-intrusively with respect to, the on-line control system to perform on-line analytics for a process without requiring the process control system to be reconfigured or recertified. The data analytics device includes a data analytics engine coupled to a logic engine that receives process data collected from the process control system in a non-intrusive manner. The logic engine operates to determine further process variable values not generated within the process control system and provides the collected process variable data and the further process variable values to the data analytics engine. The data analytics engine executes statistically based process models, such as batch models, stage models, and phase models, to produce a predicted process variable, such as an end of stage or end of batch quality variable for use in analyzing the operation of the on-line process.Type: GrantFiled: June 28, 2013Date of Patent: July 10, 2018Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Christopher J. Worek, Terrence L. Blevins, Robert B. Havekost, Dirk Thiele

Patent number: 9760651Abstract: A web services-based communication system and technique uses an information server to facilitate the communication of process control data and analysis results between a plurality of web services coupled to a communication network. A graphical user interface coupled to the network enables users to store user profile information and configuration information in a database within the information server. The information server uses the configuration information and the profile information to control the operations of a scheduler and a router within the information server to enable users to selectively view process control information via the graphical user interface and to route process control information to appropriate ones of the web services.Type: GrantFiled: June 16, 2015Date of Patent: September 12, 2017Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Neil J. Peterson, David L. Deitz, Grant Wilson, Ling Zhou, Ebtesam S. Tanyous, Christopher J. Worek, Mark J. Nixon

Patent number: 9323234Abstract: Example methods, apparatuses and systems to correlate candidate factors to a predicted fault in a process control system are disclosed. Techniques may include obtaining a value associated with a particular factor corresponding to a process, and predicting a fault based on the value. A set of candidate factors corresponding to the predicted fault may be determined, and a correlation between the predicted fault and at least one factor from the set may be displayed. Different sections of the display may respectively correspond to the predicted fault and to the at least one factor, and the correlation may be indicated by time aligning the different sections. Modifications to one displayed section may result in automatic modification of other sections to maintain the correlation. A user may select one or more candidate factors to be displayed, and may indicate a particular point of a particular section to obtain additional details.Type: GrantFiled: October 24, 2011Date of Patent: April 26, 2016Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Ling Zhou, Paul K. Daly, Robert B. Havekost, Terrence L. Blevins, Wilhelm K. Wojsznis, Mark J. Nixon, Christopher J. Worek, Paul R. Muston

Patent number: 9182752Abstract: In a batch process control system employing storage tanks without mixers, properties of the storage tank pump out feedstock may be modeled to more accurately control the quality of a process. This model may not require the measurement of input or pump out flow or assume perfect blending. Rather, the developed model may assume that feedstock input into a storage tank may remain layered with some mixing due to continuous convection, turbulence during loading, or other factors. The model may include a projection of the properties describing a storage tank layer of input material into the model. For each new load of storage tank input feedstock, model zones may be shifted and the zone from which the feedstock is drawn may be updated with the properties from the new load.Type: GrantFiled: May 9, 2011Date of Patent: November 10, 2015Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Terrence L. Blevins, Wilhelm K. Wojsznis, Christopher J. Worek

Patent number: 9086695Abstract: A data collection and viewing application associated with a batch process control system used within a process plant provides a user interface that allows a user to quickly and easily examine a particular batch process or a batch run, to compare separate batch runs and/or to determine whether the particular batch run deviates from a norm, without having to perform a lot of manual data manipulation. To this end, the user interface provides or creates a compact graphical representation of a batch, illustrating a number of different types of batch-related data in relation to one another in a manner that enables a user to easily view or understand the operation of the batch run, either alone or as compared with one or more other batch runs. Generally speaking, the compact batch view includes a number of graphical layers which are juxtaposed or interleaved on a display, with each of the layers providing different types of information about the operation of the batch, time synchronized with one another.Type: GrantFiled: May 6, 2011Date of Patent: July 21, 2015Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Christopher J. Worek, Bruce Hubert Campney, William G. Irwin, Christopher J. Felts
