A disclosed example method includes transmitting via a first wireless communication path to a first portion of a process control system associated with one of the field device or the process controller, a command signal from a verification controller. In response to receiving the command signal in the first portion of the process control system, transmitting a verification signal via a first wired communication path from the first portion of the process control system to a second portion of the process control system associated with the other one of the field device or the process controller. Then, in response to receiving the verification signal in the second portion of the process control system, transmitting a reception signal via a second wireless communication path from the second portion of the process control system to the verification controller and in response to receiving the verification signal in the verification controller, verifying the communication path between the field device and the process controller.
