1. A method of automatically generating a maintenance route in a process control system, wherein the process control system includes a wireless gateway network device and a plurality of process devices in wireless communication with the wireless gateway network device, the method implemented via one or more processors, the method comprising:

  • for each process device, beginning with the first process device, in an initial list of process devices in direct wireless communication with the wireless gateway network device, where the process devices of the initial list are ranked therein according to a signal strength of a wireless connection with the wireless gateway network device, iteratively selecting the process devices from the initial list; and

    with each iteration, appending the initial list with the remaining process devices from the plurality of process devices until the plurality of process devices are included in the appended initial list by;

    creating a subsequent list of process devices in direct wireless communication with the process device selected from the initial list, wherein the process devices of the subsequent list are ranked therein according to a signal strength of a wireless connection with the process device selected from the initial list; and

    appending the initial list with the process devices in the subsequent list, wherein each process device appended to the initial list is ranked therein after the process device selected from the initial list according to the signal strength of its wireless connection with the process device selected from the initial list, unless the process device from the subsequent list is already ranked in the initial list ahead of the selected process device from the initial list.
