Other AbstractThe invention relates to an apparatus capable of carrying out information interaction with a wired field bus device, particularly to a wireless networks for industrial automation (WIA)-PA wireless network adapter device oriented at HART equipment. With the device, the field bus device can be connected to the WIA. The positive terminal of the wireless network adapter device is used for being connected with a power supply; and the negative terminal is used for connecting a positive terminal of a wired instrument. The wireless network adapter device comprises a filtering amplifying circuit, a power supply circuit, a WIA wireless communication module, a microprocessor, a modulation-demodulation module, and a bypass protection circuit. According to the invention, the device, together with the wired instrument, is connected in series to a current loop, so that the wired instrument can be accessed to the WIA by the wireless network adapter device.
