Intrinsically-safe handheld field maintenance tool with improved help function

摘要

An intrinsically-safe handheld field maintenance tool including 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. 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 502 and to access a markup based help content store in order to display markup based help content 524, such as video content 528 or content specific to a particular field device 526, via the display. The help content may be in accordance with HyperText Markup Language (HTML). By using markup based help content, help content may be appropriately formatted for the handheld tool and may help avoid a user needing to seek out additional help content.
