Abstract
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.
Claims19
An intrinsically-safe handheld field maintenance tool comprising:
- a controller configured to automatically obtain context information prior to detecting a user input help request;
- a process communication module communicating with a field device using a process communication protocol;
- a display coupled to the controller;
- a user interface module coupled to the controller and receiving user input;
- and
- wherein, upon detecting the user input help request, the controller is configured to use the context information to responsively accesses help video content that is tagged as video content in a markup language to obtain help video content results and to apply a statistical weight to rank the help video content results to identify selected video content, and pre-processes the selected video content to render a video output on the display, the video output being in response to the user input help request.
An intrinsically-safe handheld field maintenance tool comprising:
- a controller configured to automatically obtain context information prior to detecting a user input help request;
- a process communication module communicating with a field device using a process communication protocol;
- a display coupled to the controller;
- a user interface module coupled to the controller and receiving user input;
- and
- wherein the controller, upon detecting the user input help request, is configured to use the context information to engage a help system to access a markup based help content store to obtain markup-based help content including video help content tagged as video content in a markup language to obtain video help content results and to apply a statistical weight to rank the video help results to identify selected video content and pre-process the selected video content to render the markup-based help content on the display.
A method of providing help content on an intrinsically-safe handheld field maintenance tool, the method comprising:
- communicatively coupling the intrinsically-safe handheld field maintenance tool to a field device;
- obtaining context information automatically to make relevant help information accessible to a user;
- receiving a user input requesting help;
- using the context information to access video help content tagged as video content in a markup language to obtain video help content results and to apply statistical weight to rank the video help content results to identify selected video content;
- and
- pre-processing the selected video content to render the tagged video help content on a display of the intrinsically-safe handheld field maintenance tool.
