Abstract: A handheld maintenance tool operates to detect the existence of a fault in a communication line or bus, including detecting short circuit or other low impedance faults, open circuit or other high impedance faults, etc. Additionally, the handheld maintenance tool may operate to detect an approximate location of a fault within the communication line with respect to the handheld device, to thereby enable an operator or maintenance person to more easily find and repair a detected fault.

Abstract: A portable field maintenance tool may perform one or more tasks, such as communicating with a field device, powering a field device, diagnosing a field device, or diagnosing a communication link in a plant environment to which a field device is connected. The portable field maintenance tool may interact with field devices configured according to a number of different communication protocols, such as the HART protocol and the Fieldbus protocol. The portable field maintenance tool may be energy limited and fault tolerant, and may operate in compliance with Intrinsic Safety standards, enabling use of the portable field maintenance tool in hazardous areas.

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.

Abstract: A field device includes a controller and a process communication module. The controller is configured to perform at least one operation related to process control and is also configured to perform at least one self-recovery operation relative to the field device. The process communication module is coupled to the controller and is configured to couple to a process communication segment and communicate in accordance with a process communication protocol. The controller is configured to detect an erroneous condition and selectively apply the at least one self-recovery operation in response to the detected erroneous condition.
