Patent number: 11073805Abstract: A process control system having an external data server that provides process control data to external networks via one or more firewalls implements a cost-effective security mechanism that reduces or eliminates the ability of the external data server to be compromised by viruses or other security attacks. The security mechanism includes a DMZ gateway disposed outside of the process control network that connects to an external data server located within the process control network. A configuration engine is located within the process control network and configures the external data server to publish one or more preset or pre-established data views to the DMZ gateway, which then receives the data/events/alarms as defined by the data views from the control system automatically, without performing read and write requests to the external data server.Type: GrantFiled: November 21, 2014Date of Patent: July 27, 2021Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Lee A. Neitzel, Dan H. Ussing

Patent number: 7839890Abstract: A communication technique enables the efficient transmission of data through a communication link having a large delay bandwidth product and/or a high bit error rate. The communication technique multiplexes data from one or more data sources through a plurality of communication connections to increase the overall throughput and to reduce the average data transfer delay of the communication link. Each communication connection has a set of communication connection parameters that may be uniquely configured so that each connection carries a particular type of data at a particular effective priority level. Each communication connection may be uniquely configured to have a particular sending buffer size, to deliver messages having a particular length to an underlying layer and to send the messages into the link at a particular rate to orchestrate the manner in which the communication connections send data through the link.Type: GrantFiled: November 2, 2000Date of Patent: November 23, 2010Assignee: Fisher-Rosemount Systems, Inc.Inventors: Lee A. Neitzel, Neil J. Peterson, Teresa A. Chatkoff

Publication number: 20070129820Abstract: A new and improved control system architecture with a single server interface for application software that eliminates manual intervention by providing online, immediate access to information needed for plant/enterprise optimization, operation, configuration, maintenance and diagnostic application software. The control system architecture provides a method of dynamically creating a server directory to enable automatic access in an integrated control system. The method includes accessing a live list of fieldbus devices, building/updating a browse tree structure, the browse tree structure defining a branch and leaf node organization and naming for and data from the fieldbus devices, copying AP directories and FF objects from active fieldbus devices into a FF directory and mapping the FF Directory into the server directory.Type: ApplicationFiled: November 16, 2006Publication date: June 7, 2007Inventors: David Glanzer, Lee Neitzel, Donald Goff

Publication number: 20050240287Abstract: A distributed control system architecture (HSE) provides an open, interoperable solution optimized for integration of distributed control systems and other control devices in a high performance backbone, provides an open, interoperable solution that provides system time synchronization suitable for distributed control applications operable over a high performance backbone, and provides an open, interoperable solution that provides a fault tolerant high performance backbone as well as fault tolerant devices that are connected to the backbone. The distributed control system architecture comprises a High speed Ethernet Field Device Access (HSE FDA) Agent, which maps services of a distributed control system, e.g., a fieldbus System, to and from a standard, commercial off-the-shelf (COTS) Ethernet/Internet component.Type: ApplicationFiled: June 22, 2004Publication date: October 27, 2005Inventors: David Glanzer, Colin Corles, Steven Brodman, William Hawkins, Michael Hirst, Tony Kozlik, Lee Neitzel, Raymond Sawyer, Johan Tegnell

Patent number: 6594530Abstract: 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.Type: GrantFiled: June 4, 2002Date of Patent: July 15, 2003Assignee: Fieldbus FoundationInventors: David A. Glanzer, Terrence L. Blevins, Ram Ramachandran, Kenneth D. Krivoshein, Patricia E. Brett, Jack Elias, William R. Hodson, Frank Lynch, Ashok K. Gupta, Lee A. Neitzel, Thomas B.
