Handheld maintenance tool

A portable field maintenance tool system for performing a plurality of different functional tasks on one or more equipment assets in a plant includes a handheld base and a plurality of functional modules for attachment to the handheld base. Each functional module, when operatively attached to the handheld base, interacts with computer circuits on the handheld base to perform a pre-defined one or more of the functional tasks. A portable handheld field maintenance tool for performing one or more pre-selected ones of the functional tasks on an equipment asset in a plant is formed by operatively mounting any one of the functional modules to the handheld base.

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.

A platform-to-platform communication architecture for a process control messaging service in a process control system or other industrial setting allows stationary and portable industrial computing units to communicate with each other, in one-to-one and one-to-many communications, and across networks, including isolated networks inside the process control system or industrial setting and external networks. A requesting industrial computing device platform generates a message for a destination, or responding, industrial computing device in the communication protocol of the destination platform, and wraps the message in a communication protocol of the process control messaging service. The communication architecture decodes the wrapped message into the communication protocol of the destination industrial computing device and forwards the decoded wrapped message to the destination. The communication architecture allows for a variety of communication services, including, but not limited to, instant/real-time peer-to-peer messaging, time synchronization, automatic data transfer with an asset management system, communication with field devices via an asset management system and large data transfers.

A handheld field maintenance tool with improved functionality is provided. The handheld field maintenance tool includes a keypad, a display, a short-range wireless transceiver and a processor. The processor is coupled to the keypad, the display and the short-range wireless transceiver. The processor is also coupled to memory having a plurality of instructions stored therein, which instructions, when executed by the processor, cause the processor to perform at least one of remote wireless display; remote wireless keypress injection; and wireless printing.

Handheld field maintenance tool with improved functionality

A method of evaluating a potential location to add a wireless field device to an existing network of a plurality of existing wireless field devices is provided. The method includes placing a handheld field maintenance tool in the potential location and causing the handheld field maintenance tool to identify wireless field devices within communicative range of the potential location. Information related to wireless communication at the potential location is viewed. Methods are also provided for identifying a selected field device in a process installation using a handheld field maintenance tool.
