Embodiment Construction

[0015] An improved intrinsically safe field maintenance tool in accordance with embodiments of the present invention is capable of operating with at least two industry standard device descriptions. The tool comprises at least two power islands electrically isolated in a manner that satisfies intrinsic safety requirements. In a specific embodiment, the improved intrinsically safe field maintenance tool implements a HART  and Fieldbus Device Description Language (DDL). Improved field maintenance tools are used to maintain both two-wire and four-wire (ie, externally powered) field devices using these protocols. Configuration and calibration are preferably supported by DDL techniques. DDL technology is known and additional reading on Device Description Language can be found in US Patent 5,960,214 to Sharp Jr. et al.

[0016] The improved intrinsically safe field maintenance tool facilitates convenient display of diagnostic information (ie, status bits) from individual field de...

Abstract

An intrinsically safe field maintenance tool includes terminals selectively connectable to a process communication ring having a process industry standard communication protocol. At least one medium access unit is configured to communicate in accordance with a first process industry standard communication protocol. The battery pack connector is adapted to be removably connected to a removable battery pack and to provide power to circuits in the intrinsically safe field maintenance tool. An intrinsically safe battery pack is also proposed.

Description

technical field [0001] The present invention relates to an intrinsically safe field maintenance tool with a removable battery pack. Background technique [0002] Intrinsically safe field maintenance tools are known. Such tools are particularly useful in the process control and measurement industries to allow operators to conveniently communicate with and / or interrogate field devices in a given process installation. Examples of such process installations include: petroleum, pharmaceutical, chemical, pulp and other process installations. In such installations, process control and measurement networks may include dozens or even hundreds of various field devices that periodically require maintenance to ensure proper operation of such devices and / or to calibration. Furthermore, when one or more faults in a process control and measurement installation are detected, the use of an intrinsically safe handheld field maintenance tool enables a technician to quickly diagnose such fau...
