Publication number: 20220053074Abstract: A field device includes components to communicate with a control and/or asset management system of a process control system or with other field devices using any of several different communication protocols such as several different internet protocol (IP) protocols. This architecture allows for a single version of a field device to be provided in automation or plant control systems that use any of these communication protocols, thus saving on inventory and product development costs. Moreover, the multi-protocol field device or a system using the multi-protocol field device can manage the asset (read and write parameterized data from and to the asset) using one protocol while at the same time communicating real-time process/factory automation information using a second and different protocol. Moreover, the field device may be able to communicate to other devices including other field devices and host devices using both of these protocols or other protocols for different purposes.Type: ApplicationFiled: August 30, 2021Publication date: February 17, 2022Inventors: Martin Zielinski, Donald R.

Patent number: 9201414Abstract: An intrinsically-safe handheld field maintenance tool includes a process communication module configured communicatively couple to a field device. A camera is configured to obtain at least one image relative to the field device. A controller is coupled to the process communication module and operably coupled to the camera. The controller is configured to store the at least one image relative to the field device. The handheld field maintenance tool may also include or employ an audio input device to capture audio files.Type: GrantFiled: July 27, 2011Date of Patent: December 1, 2015Assignee: Fisher-Rosemount Systems, Inc.Inventors: Christopher P. Kantzes, Brad N. Mathiowetz, Todd M. Toepke, Kun Yang, Adam E. Lund, Donald R. Lattimer, Brian A. Franchuk

Patent number: 8766794Abstract: A handheld field maintenance tool is provided. The tool includes, among other things, a wireless process communication protocol module configured to communicate in accordance with a wireless process communication protocol. The tool also includes a display and an input device. A controller is coupled to the wireless process communication protocol module, the display, and the input device. The controller is configured to generate a map on the display indicating a position of the handheld field maintenance device relative to at least one asset, such as a field device. The controller is further configured to determine a position of the handheld field maintenance device by triangulating using wireless process communication with a number of known, fixed-position wireless field devices.Type: GrantFiled: July 27, 2011Date of Patent: July 1, 2014Assignee: Fisher-Rosemount Systems, Inc.Inventors: Anthony D. Ferguson, Christopher P. Kantzes, Brad N. Mathiowetz, Todd M. Toepke, Kun Yang, Adam E. Lund, Donald R. Lattimer, Brian A. Franchuk

Patent number: 7246193Abstract: An interface module is operatively coupled to a Fieldbus process control network and a Modbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a register map database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to register numbers of the Modbus process control network. Once the Fieldbus process control parameters are mapped to the Modbus registers, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the register map database.Type: GrantFiled: January 30, 2003Date of Patent: July 17, 2007Assignee: Rosemount, Inc.Inventors: Eric D. Rotvold, Donald R. Lattimer, Michael J. Green, Robert J. Karschnia, Marcos A. V. Peluso
