Abstract

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.

Claims

1. A method of evaluating a potential location within a process environment for addition of a wireless field device to an existing network of a plurality of existing wireless field devices, the method comprising:

placing a handheld field maintenance tool in the potential location;

causing the handheld field maintenance tool to identify wireless field devices within communicative range of the potential location;

viewing information, on a display of the handheld field maintenance tool, related to wireless communication at the potential location, wherein information related to wireless communication at the potential location comprises a device identifier and a signal strength for each identified wireless field device;

providing a recommendation of which wireless sensor network the wireless field device should join; and

wherein the handheld field maintenance tool is intrinsically safe.

2. The method of claim 1, wherein the handheld field maintenance tool communicates with each wireless field device in accordance with a process industry standard protocol.

3. The method of claim 2, wherein the process industry standard protocol is a WirelessHART protocol.

4. The method of claim 1, wherein the information related to wireless communication at the potential location includes an indication of electromagnetic interference.

5. The method of claim 1, and further comprising:

providing an indication of anticipated communication reliability for the wireless device at the potential location.

6. The method of claim 1, and further comprising:

providing a graphic representation of detected signal strength as a function of a detected position of each identified wireless field device.
