  • Publication number: 20220053074
    Abstract: 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.

  • Patent number: 9201414
    Abstract: 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.

  • Patent number: 8766794
    Abstract: 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.

  • Patent number: 7321846
    Abstract: A diagnostic device for coupling to a process control loop includes digital communication circuitry configured to receive a digital communication signal from the process control loop. The digital communication signal is a digitally modulated analog signal on the process control loop which is modulated to a plurality of discrete analog signal levels representative of digital values. Diagnostic circuitry diagnoses operation of the process control loop which may include field devices of the process control loop based upon the digitally modulated analog signal.

  • Patent number: 7246193
    Abstract: 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.
