A handheld field maintenance tool with improved diagnostic functions is provided. The tool includes a process communication module configured to interact with a field device. A controller is coupled to the process communication module. The controller is configured to execute a number of improved diagnostic functions relative to the field device. The controller may obtain contextual information relative to a current field maintenance operation and preload at least one resource relative to a next field operation step. The controller may obtain process alarm information through a wireless communication module, and field device alert information through the process communication module and provide an indication on a display relative to both process alarm information and field device alert information. The controller may execute a sequence of field device maintenance operations on the field device in response to a signal from a user input device. The controller may obtain snapshot information in response to a signal from a user input device.

A handheld field maintenance tool is provided. The handheld field maintenance tool includes a process communication module configured to communicate with a field device. The handheld field maintenance tool also includes a display and a user input device. A controller is coupled to the process communication module, the user input device and the display and is configured to generate a listing of task-based field maintenance operations on the display and receive a user input selecting a task-based field maintenance operation. The controller is configured to automatically traverse a menu of the field device using a fast-key sequence relative to the selected task. A method of creating a task-based field maintenance operation is provided. A method of interacting with a field device menu is also provided.

In responsive to receiving a user interaction with a map graphical user interface (GUI) of a client device, the system identifies an origin, and determines a map zoom level and map position based on the interaction. The system identifies and ranks candidate destinations for the origin. The system automatically selects destinations from the ranked candidates for inclusion in the map based on the zoom level and the position. Each selected destination for which a destination location indicator would be obscured in the map by an indicator of a higher ranked destination is automatically determined by the system. The system then deselects each destination for which a location indicator has been determined to be obscured by an indicator of a higher ranked destination, forming a revised set of destinations. The system transmits instructions to display a location indicator for each destination in the revised set to the client device.

An intrinsically-safe handheld field maintenance tool includes a controller, a process communication module, and a display. The process communication module is configured to communicate with a field device using a process communication protocol. The display is coupled to the controller. A user interface module is also coupled to the controller and is configured to receive user input. The controller is configured to detect a user input help request and provide a video output on the display in response to the user input help request.
