Abstract: An interface module according to one aspect of the invention includes an interface and a local communication device. The interface, which is connected to a field device, receives a first wireless signal from the field device. The local communication device wirelessly transmits the first signal to a wireless module by first local communications. The local communication device receives, from the wireless module by second local communications, a second signal destined for the field device that is wirelessly transmitted from an external device and wirelessly received by the wireless device. The interface device outputs the second signal to the field device.
