Maintenance of an industrial process sensor network may present various challenges. One problem may be the ability to obtain real or near-real time control and monitoring of machines that carry on processes and sensors for monitoring or tracking the performance of these machines. Conventional solutions include constructing and commissioning wired transmitters, which are electrically connected to a control system, e.g., a Distributed Control System (DCS), a programmable logic controller (PLC), etc., in the field. Such solutions include the following two approaches: (a) configuring a database of wired transmitters from the control system, or (b) creating an off-line database of transmitters in the control system at an engineering facility and downloading the database to transmitters following wired connection in the field.
Various wireless network technologies are known and used for measurement data collection. Advantages of wireless sensor network technology include the lack of wiring and thus reduce cost of cabling, junction boxes, trenches, and I/O connections. In addition, wireless sensor network technology may reduce the commissioning time of field sensors. However, wireless sensor networks and wireless handheld devices may utilize different communication protocol. For example, wireless sensor network may employ wireless sensor network standards such as Wireless HART ISA100.11a, and other standard or proprietary wireless protocols. Further, current solutions require significant on-site installation activity by maintenance personnel. For example, maintenance personnel may have to spend significant time programming a device on-site based on variances in signal strength, accessibility, wiring and/or power requirements, etc. These and other difficulties make existing solutions for on-site or field sensor commissioning unattractive.

A “process” as used herein with respect to computer components is generally conceived to be a sequence of processor or computer-executable steps leading to a desired result. These steps generally require physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical, magnetic, or optical signals capable of being stored, transferred, combined, compared, or otherwise manipulated. It is convention for those skilled in the art to refer to these signals as bits, values, elements, symbols, characters, terms, objects, numbers, records, files or the like. It should be kept in mind, however, that these and similar terms should be associated with appropriate physical quantities for computer operations, and that these terms are merely conventional labels applied to physical quantities that exist within and during operation of the computer.
It should also be understood that manipulations within the computer are often referred to in terms such as adding, comparing, moving, etc., which are often associated with manual operations performed by a human operator. It is understood that no such involvement of a human operator is necessary or even desirable in the present invention. The operations described herein are machine operations performed in conjunction with human operators) or users) who interact with the computer(s). The machines used for performing the operation of the present invention include general digital computers or other similar processing devices.
In addition, it should be understood that the programs, processes, methods, etc., described herein are not related or limited to any particular computer or apparatus.
