Embodiment Construction

[0056] While the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words and equivalents of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment, since describing every possible embodiment would be impractical. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims.

[0057] figure 1 A process control system 100 is shown that includes a process control device 105, which in some embodiments may be a FOUNDATION field equipment, Transmitters or locators, or other devices according to embodiments of the present disclosure. The process control device may be communicatively coupled to a handheld field maintenance (F...

Abstract

Multi-functional field maintenance (FM) tools that connect to process control devices, such as FOUNDATION Fieldbus and Highway Addressable Remote Transducer devices, can automatically detect and simultaneously identify communications, troubleshoot connections, and supply power in a process control plant. Simplifying the troubleshooting process, by guiding a user of a multi-functional FM tool through recommended troubleshooting steps, while simultaneously detecting and correcting issues reduces the number of tools required to maintain process control devices, reduces the risk of damage, and improves efficiency by minimizing production downtime.

Description

technical field [0001] The present disclosure relates generally to field maintenance tools for process control systems and, more particularly, to field maintenance tools optimized to operate in the presence of hazardous conditions in process control systems. Background technique [0002] Process control systems, like those used in chemical, petroleum processes, typically include communicatively coupled via analog, digital, or combined analog / digital communication links to at least one host or operator workstation and one or more field One or more process controllers of the equipment. [0003] Field devices are typically or include actuators, sensors, or some combination thereof. Field devices perform functions within a process plant, such as opening or closing valves and measuring process parameters. Example field devices include valves, valve positioners, switches, pumps, and transmitters (eg, for transmitting measurements obtained via temperature, pressure, or flow senso...
