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.

Multi-protocol field device in process control systems

A process control system coordinates with an associated asset management system to implement a plant safety mechanism and, in particular, to prevent unintended changes to, or otherwise undesired operation of, one or more process control equipment resources in a process plant. A maintenance technician uses the asset management system to request access to one or more of the process control equipment resources. A process operator receives the request via the process control system and grants or denies the request. Process control equipment resources for which a process operator grants a request are inoperable, in part or in whole, by the process control system. Upon completion of the maintenance task, the maintenance technician requests to return control of the process control equipment resource to the process operator. The return is complete when the process operator acknowledges the return of the resource to the process control system.

Software lockout coordination between a process control system and an asset management system

Example methods and apparatus to display process control information are disclosed. A disclosed example method includes receiving in a processor a first status of a first mode element, the first mode element indicating a current operating condition of an object of a process control device, receiving in the processor a second status of a second mode element, the second mode element indicating a desired operating condition of the object of the process control device, determining a mode of the object based on the first status and the second status, the mode indicating a condition of the object of the process control device, and displaying the mode of the object of the process control device within a user interface as a graphic.

Methods and apparatus to display process control device information

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.

Intrinsically-safe handheld field maintenance tool with image and/or sound capture

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.

Handheld field maintenance tool with improved locational awareness functionality

A method of interacting with a process control system is provided. The method includes bringing a mobile electronic device into physical proximity of a field device. The mobile electronic device is coupled to a digital process communication channel of the field device. A client software application is initiated on the mobile electronic device. The digital process communication channel is used to communicatively couple the client software application to a host application remote from both the mobile electronic device and the field device.

Handheld field maintenance tool with process communication tunnel

Field devices on a communication network can be configured using a configuration device that stores a configuration data for each of the field devices in a network configuration domain in nonvolatile memory. Each field device includes a configuration domain associated with configuration data stored in nonvolatile memory of the field device. In response to commands from the configuration device, the field devices upload configuration data to or download configuration data from the configuration device. Field devices receive configuration data from the configuration device and store the received configuration data in the nonvolatile memory to define the configuration of the field device.

Configuration of field devices on a network

An interface module for use in a process monitoring and control system has an Ethernet port, a controller, and at least one segment I/O module. The Ethernet port is adapted to send and receive signals in an Ethernet protocol over a cable comprising a plurality of wires and to receive a voltage potential from at least one pair of the plurality of wires. The controller is coupled to the Ethernet port and powered from the received voltage potential. The at least one segment I/O module is coupled to the controller and is adapted to couple to an associated field device segment with at least one attached field device. The at least one segment I/O module is adapted to interact with the at least one attached field device on the associated field device segment.

Interface module with power over Ethernet function

A device for diagnosing operation of an industrial process control or monitoring system includes an input configured to receive an input related to a process signal. A first statistical parameter module provides a first statistical parameter output related to a statistical parameter of the process signal. A filter provides a filter output related to a filtered value of the process signal. A second statistical parameter module provides a second statistical parameter output related to a statistical parameter of the filter output. A diagnostic module diagnoses operation of the industrial process based upon the first and second statistical parameters.

Diagnostics in industrial process control system

A diagnostic field device for coupling to a two-wire process control loop of an industrial process control or monitoring system includes digital communication monitoring circuitry which is configured to couple to a two-wire process control loop. The digital communication monitoring circuitry is configured to receive a digital communication signal from the two-wire process control loop. Timing circuitry in the diagnostic field device provides a timing output. Diagnostic circuitry provides a diagnostic output based upon the digital communication signal and the timing output.

Field device for digital process control loop diagnostics

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.

Two-wire process control loop diagnostics

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.
