具有改进诊断的手持现场维护工具
摘要：
本发明提供了一种具有改进诊断功能的手持现场维护工具(52，102)。所述工具(52，102)包括：过程通信模块(121，138)，被配置为与现场设备(22，23，104)交互。控制器(130)耦合至过程通信模块(121，138)。所述控制器(130)被配置为执行与现场设备(22，23，104)相关的多个改进诊断功能。所述控制器(130)可以获得与当前现场维护操作相关的上下文信息(206)，并预加载与下一现场操作步骤相关的至少一个资源(208)。所述控制器(130)可以通过无线通信模块(123)获得过程警报信息(254)，通过过程通信模块(121，138)获得现场设备警告信息(254)，并在显示器(120)上提供与过程警报信息和现场设备警告信息相关的指示。所述控制器(130)可以响应于来自用户输入设备(122)的信号，对现场设备执行现场设备维护操作序列。所述控制器(130)可以响应于来自用户输入设备(122)的信号，获得快照信息(304)。
摘要（英）：

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).
