HANDHELD FIELD MAINTENANCE TOOL WITH IMPROVED DIAGNOSTICS

摘要

A handheld field maintenance tool (52, 102) with improved diagnostic functions is provided. The tool (52, 102) includes a process communication module (121, 138) configured to interact with a field device (22, 23, 104). A controller (130) is coupled to the process communication module (121, 138). The controller (130) is configured to execute a number of improved diagnostic functions relative to the field device (22, 23, 104). The controller (130) may obtain contextual information (206) relative to a current field maintenance operation and preload at least one resource relative to a next field operation step (208). The controller (130) may obtain process alarm information (254) through a wireless communication module (123), and field device alert information (254) through the process communication module (121, 138) and provide an indication on a display (120) relative to both process alarm information and field device alert information. The controller (130) may execute a sequence of field device maintenance operations on the field device in response to a signal from a user input device (122). The controller (130) may obtain snapshot information (304) in response to a signal from a user input device (122).
